Energy offers rebates to customers who use solar systems in residential and commercial applications.

Mark Stutz, Xcel spokesman, said the company has paid nearly $31.3 million in rebates and purchases of Renewable Energy Credits through its Solar Rewards Program. Those payments went to 1,525 consumers, Stutz said, adding the company has received nearly 2,300 applications.

Xcel will rebate customers $2 per watt of solar panels installed on customer premises, up to 10,000 watts - or 10 kilowatts. Also as part of the program, the company will buy Renewable Energy Credits generated by customer systems for $2.50 per watt. These credits then will be counted toward the company's Renewable Energy Standard requirements, which were approved by voters in November 2004 under Amendment 37 and subsequently clarified by the legislature in the 2005 session.

The combination of the rebates and the credits will generate a total return to customers of $4.50 per watt under the Solar Rewards program.

Total payments to customers through Solar Rewards would be in the $9,000 to $13,500 range, depending on two or three kilowatts of demand. Consumers also may pursue federal government tax credits for about $2,000, which covers about half the installation cost.

In total, more than 5.84 megawatts of capacity has been added to the grid from the Solar Rewards Program for less than 10 kilowatts of demand. One megawatt-hour typically serves about 750 homes in Colorado, Stutz said.

Is tidal energy the surge remote coastal communities need?

BC Tidal Energy Micro-Grids harness predictable tidal currents to replace diesel in remote Indigenous coastal communities, integrating marine renewables, storage, and demand management for resilient off-grid power along Vancouver Island and Haida Gwaii.

 

Key Points

Community-run tidal turbines and storage deliver reliable, diesel-free electricity to remote B.C. coastal communities.

✅ Predictable power from tidal currents reduces diesel dependence

✅ Integrates storage, demand management, and microgrid controls

✅ Local jobs via marine supply chains and community ownership

 

Many remote West Coast communities are reliant on diesel for electricity generation, which poses a number of negative economic and environmental effects.

But some sites along B.C.’s extensive coastline are ideal for tidal energy micro-grids that may well be the answer for off-grid communities to generate clean power, suggested experts at a COAST (Centre for Ocean Applied Sustainable Technologies) virtual event Wednesday.

There are 40 isolated coastal communities, many Indigenous communities, and 32 of them are primarily reliant on diesel for electricity generation, said Ben Whitby, program manager at PRIMED, a marine renewable energy research lab at the University of Victoria (UVic).

Besides being a costly and unreliable source of energy, there are environmental and community health considerations associated with shipping diesel to remote communities and running generators, Whitby said.

“It's not purely an economic question,” he said.

“You've got the emissions associated with diesel generation. There's also the risks of transporting diesel … and sometimes in a lot of remote communities on Vancouver Island, when deliveries of diesel don't come through, they end up with no power for three or four days at a time.”

The Heiltsuk First Nation, which suffered a 110,000-litre diesel spill in its territorial waters in 2016, is an unfortunate case study for the potential environmental, social, and cultural risks remote coastal communities face from the transport of fossil fuels along the rough shoreline.

A U.S. barge hauling fuel for coastal communities in Alaska ran aground in Gale Pass, fouling a sacred and primary Heiltsuk food-harvesting area.

There are a number of potential tidal energy sites near off-grid communities along the mainland, on both sides of Vancouver Island, and in the Haida Gwaii region, Whitby said.

Tidal energy exploits the natural ebb and flow of the coast’s tidal water using technologies like underwater kite turbines to capture currents, and is a highly predictable source of renewable energy, he said.

Micro-grids are self-reliant energy systems drawing on renewables from ocean, wave power resources, wind, solar, small hydro, and geothermal sources.

The community, rather than a public utility like BC Hydro, is responsible for demand management, storage, and generation with the power systems running independently or alongside backup fuel generators — offering the operators a measure of energy sovereignty.

Depending on proximity, cost, and renewable solutions, tidal energy isn’t necessarily the solution for every community, Whitby noted, adding that in comparison to hydro, tidal energy is still more expensive.

However, the best candidates for tidal energy are small, off-grid communities largely dependent on costly fossil fuels, Whitby said.

“That's really why the focus in B.C. is at a smaller scale,” he said.

“The time it would take (these communities) to recoup any capital investment is a lot shorter.

“And the cost is actually on a par because they're already paying a significant amount of money for that diesel-generated power.”

Lisa Kalynchuk, vice-president of research and innovation at UVic, said she was excited by the possibilities associated with tidal power, not only in B.C., but for all of Canada’s coasts.

“Canada has approximately 40,000 megawatts available on our three coastlines,” Kalynchuk said.

“Of course, not all this power can be realized, but it does exist, so that leads us to the hard part — tapping into this available energy and delivering it to those remote communities that need it.”

Challenges to establishing tidal power include the added cost and complexity of construction in remote communities, the storage of intermittent power for later use, the economic model, though B.C.’s streamlined regulatory process may ease approvals, the costs associated with tidal power installations, and financing for small communities, she said.

But smaller tidal energy projects can potentially set a track record for more nascent marine renewables, as groups like Marine Renewables Canada pivot to offshore wind development, at a lower cost and without facing the same social or regulatory resistance a large-scale project might face.

A successful tidal energy demo project was set up using a MAVI tidal turbine in Blind Channel to power a private resort on West Thurlow Island, part of the outer Discovery Islands chain wedged between Vancouver Island and the mainland, Whitby said.

The channel’s strong tidal currents, which routinely reach six knots and are close to the marina, proved a good site to test the small-scale turbine and associated micro-grid system that could be replicated to power remote communities, he said.

The mooring system, cable, and turbine were installed fairly rapidly and ran through the summer of 2017. The system is no longer active as provincial and federal funding for the project came to an end.

“But as a proof of concept, we think it was very successful,” Whitby said, adding micro-grid tidal power is still in the early stages of development.

Ideally, the project will be revived with new funding, so it can continue to act as a test site for marine renewable energy and to showcase the system to remote coastal communities that might want to consider tidal power, he said.

In addition to harnessing a local, renewable energy source and increasing energy independence, tidal energy micro-grids can fuel employment and new business opportunities, said Whitby.

The Blind Channel project was installed using the local supply chain out of nearby Campbell River, he said.

“Most of the vessels and support came from that area, so it was all really locally sourced.”

Funding from senior levels of government would likely need to be provided to set up a permanent tidal energy demonstration site, with recent tidal energy investments in Nova Scotia offering a model, or to help a community do case studies and finance a project, Whitby said.

Both the federal and provincial governments have established funding streams to transition remote communities away from relying on diesel.

But remote community projects funded federally or provincially to date have focused on more established renewables, such as hydro, solar, biomass, or wind.

The goal of B.C.’s Remote Community Energy Strategy, part of the CleanBC plan and aligned with zero-emissions electricity by 2035 targets across Canada, is to reduce diesel use for electricity 80 per cent by 2030 by targeting 22 of the largest diesel locations in the province, many of which fall along the coast.

The province has announced a number of significant investments to shift Indigenous coastal communities away from diesel-generated electricity, but they predominantly involve solar or hydro projects.

A situation that’s not likely to change, as the funding application guide in 2020 deemed tidal projects as ineligible for cash.

Yet, the potential for establishing tidal energy micro-grids in B.C. is good, Kalynchuk said, noting UVic is a hub for significant research expertise and several local companies, including ocean and river power innovators working in the region, are employing and developing related service technologies to install and maintain the systems.

“It also addresses our growing need to find alternative sources of energy in the face of the current climate crisis,” she said.

“The path forward is complex and layered, but one essential component in combating climate change is a move away from fossil fuels to other sources of energy that are renewable and environmentally friendly.”

Texas utilities struggle to restore power as Harvey hampers progress

Texas Gulf Coast Power Outages from Harvey continue as flooding, high winds, and downed lines paralyze Houston and coastal utilities, while restoration crews from out-of-state work to repair infrastructure and restore electricity across impacted communities.

 

Key Points

Power disruptions across Houston and the Gulf Coast from Harvey, driven by flooding, wind damage, and blocked access.

✅ CenterPoint warns multi-day outages in flooded zones.

✅ AEP Texas aided by crews from Kentucky, Illinois, Missouri.

✅ Entergy expects more outages as storm nears Galveston.

 

Hundreds of thousands of Texans were without power along the Gulf Coast as Tropical Storm Harvey left parts of the Houston area under water, with extended Houston outages compounding response efforts.

There were roughly 280,000 customers without power along the Texas's coast and in Houston and the surrounding areas on Monday, according to reported outages by the state's investor-owned utilities. Harvey, which made landfall on Friday, caused devastating flooding and knocked out power lines along its destructive path, similar to the Louisiana grid rebuild after Laura that required weeks of restoration.

CenterPoint Energy reported more than 100,000 outages earlier on Monday, though that figure was down to 91,744 shortly after 1 p.m. on Monday.

The company said it was unable to access hard-hit areas until floodwaters recede and electric infrastructure dries out, a challenge that, as seen in Florida power restoration efforts elsewhere, has taken weeks to resolve. Outages in the most flooded areas could last for several days, CenterPoint warned.

AEP Texas's coverage area south of Houston had 150,500 customers without electricity as of 11 a.m. ET on Monday. That was down from the peak of its outages on Saturday afternoon, which affected 220,000 customers.

Former FEMA deputy director: Texas has already begun recovery from storm  1:54 PM ET Mon, 28 Aug 2017 | 05:57

Corpus Christi and the surrounding areas along the Gulf Coast were still experiencing the most outages, while persistent Toronto outages after a spring storm underscored how long recovery can take in urban areas. AEP credited assistance from out-of-state workers for helping to get the lights back on.

"Thousands of resources have arrived from across the country to help AEP Texas with restoration efforts following this historic weather event. Crews from Kentucky, Illinois, Missouri and other states have arrived and are working on restoring power to those impacted by Hurricane Harvey," AEP said in a statement.

Entergy reported 29,500 customers were without power on Monday in areas north of Houston. The company warned that additional outages were expected if Harvey moves inland near the island city of Galveston on Wednesday as anticipated, a pattern similar to New Orleans during Ida where electricity failed despite levees holding.

Houston, Beaumont and Victoria are expected to see continued periods of torrential rain through Tuesday, before Harvey begins to move north on Wednesday and out of the flood zone by Thursday.

"Our crews are safely restoring power as quickly as possible, but the continued wind, rain and flooding are having an impact on restoration efforts," Entergy said in a statement.

South of Houston, about 7,500 Texas New Mexico Power Company customers were still experiencing outages, according to the company's outage map.

Grid coordination opens road for electric vehicle flexibility

Smart EV Charging orchestrates vehicle-to-grid (V2G), demand response, and fast charging to balance the power grid, integrating renewables, electrolyzers for hydrogen, and megawatt chargers for fleets with advanced control and co-optimization.

 

Key Points

Smart EV charging coordinates EV load to stabilize the grid, cut peaks, and integrate renewable energy efficiently.

✅ Reduces peak demand via coordinated, flexible load control

✅ Enables V2G services with renewables and battery storage

✅ Supports megawatt fast charging for heavy-duty fleets

 

As electric vehicle (EV) sales continue to rev up in the United States, the power grid is in parallel contending with the greatest transformation in its 100-year history: the large-scale integration of renewable energy and power electronic devices. The expected expansion of EVs will shift those challenges into high gear, causing cities to face gigawatt-growth in electricity demand, as analyses of EV grid impacts indicate, and higher amounts of variable energy.

Coordinating large numbers of EVs with the power system presents a highly complex challenge. EVs introduce variable electrical loads that are highly dependent on customer behavior. Electrified transportation involves co-optimization with other energy systems, like natural gas and bulk battery storage, including mobile energy storage flexibility for new operational options. It could involve fleets of automated ride-hailing EVs and lead to hybrid-energy truck stops that provide hydrogen and fast-charging to heavy-duty vehicles.

Those changes will all test the limits of grid integration, but the National Renewable Energy Laboratory (NREL) sees opportunity at the intersection of energy systems and transportation. With powerful resources for simulating and evaluating complex systems, several NREL projects are determining the coordination required for fast charging, balancing electrical supply and demand, and efficient use of all energy assets.


Smart and Not-So-Smart Control
To appreciate the value of coordinated EV charging, it is helpful to imagine the opposite scenario.

"Our first question is how much benefit or burden the super simple, uncoordinated approach to electric vehicle charging offers the grid," said Andrew Meintz, the researcher leading NREL's Electric Vehicle Grid Integration team, as well as the RECHARGE project for smart EV charging. "Then we compare that to the 'whiz-bang,' everything-is-connected approach. We want to know the difference in value."

In the "super simple" approach, Meintz explained that battery-powered electric vehicles grow in market share, exemplified by mass-market EVs, without any evolution in vehicle charging coordination. Picture every employee at your workplace driving home at 5 p.m. and charging their vehicle. That is the grid's equivalent of going 0 to 100 mph, and if it does not wreck the system, it is at least very expensive. According to NREL's Electrification Futures Study, a comprehensive analysis of the impacts of widespread electrification across all U.S. economic sectors, in 2050 EVs could contribute to a 33% increase in energy use during peak electrical demand, underscoring state grid challenges that make these intervals costly when energy reserves are procured. In duck curve parlance, EVs will further strain the duck's neck.

Meintz's "whiz-bang" approach instead imagines EV control strategies that are deliberate and serve to smooth, rather than intensify, the upcoming demand for electricity. It means managing both when and where vehicles charge to create flexible load on the grid.

At NREL, smart strategies to dispatch vehicles for optimal charging are being developed for both the grid edge, where consumers and energy users connect to the grid, as in RECHARGEPDF, and the entire distribution system, as in the GEMINI-XFC projectPDF. Both projects, funded by the U.S. Department of Energy's (DOE's) Vehicle Technologies Office, lean on advanced capabilities at NREL's Energy Systems Integration Facility to simulate future energy systems.

At the grid edge, EVs can be co-optimized with distributed energy resources—small-scale generation or storage technologies—the subject of a partnership with Eaton that brought industry perspectives to bear on coordinated management of EV fleets.

At the larger-system level, the GEMINI-XFC project has extended EV optimization scenarios to the city scale—the San Francisco Bay Area, to be specific.

"GEMINI-XFC involves the highest-ever-fidelity modeling of transportation and the grid," said NREL Research Manager of Grid-Connected Energy Systems Bryan Palmintier.

"We're combining future transportation scenarios with a large metro area co-simulationPDF—millions of simulated customers and a realistic distribution system model—to find the best approaches to vehicles helping the grid."

GEMINI-XFC and RECHARGE can foresee future electrification scenarios and then insert controls that reduce grid congestion or offset peak demand, for example. Charging EVs involves a sort of shell game, where loads are continually moved among charging stations to accommodate grid demand.

But for heavy-duty vehicles, the load is harder to hide. Electrified truck fleets will hit the road soon, creating power needs for electric truck fleets that translate to megawatts of localized demand. No amount of rerouting can avoid the requirements of charging heavy-duty vehicles or other instances of extreme fast-charging (XFC). To address this challenge, NREL is working with industry and other national laboratories to study and demonstrate the technological buildout necessary to achieve 1+ MW charging stationsPDF that are capable of fast charging at very high energy levels for medium- and heavy-duty vehicles.

To reach such a scale, NREL is also considering new power conversion hardware based on advanced materials like wide-bandgap semiconductors, as well as new controllers and algorithms that are uniquely suited for fleets of charge-hungry vehicles. The challenge to integrate 1+ MW charging is also pushing NREL research to higher power: Upcoming capabilities will look at many-megawatt systems that tie in the support of other energy sectors.


Renewable In-Roads for Hydrogen

At NREL, the drive toward larger charging demands is being met with larger research capabilities. The announcement of ARIES opens the door to energy systems integration research at a scale 10-times greater than current capabilities: 20 MW, up from 2 MW. Critically, it presents an opportunity to understand how mobility with high energy demands can be co-optimized with other utility-scale assets to benefit grid stability.

"If you've got a grid humming along with a steady load, then a truck requires 500 kW or more of power, it could create a large disruption for the grid," said Keith Wipke, the laboratory program manager for fuel cells and hydrogen technologies at NREL.

Such a high power demand could be partially served by battery storage systems. Or it could be hidden entirely with hydrogen production. Wipke's program, with support from the DOE's Hydrogen and Fuel Cell Technologies Office, has been performing studies into how electrolyzers—devices that use electricity to break water into hydrogen and oxygen—could offset the grid impacts of XFC. These efforts are also closely aligned with DOE's H2@Scale vision for affordable and effective hydrogen use across multiple sectors, including heavy-duty transportation, power generation, and metals manufacturing, among others.

"We're simulating electrolyzers that can match the charging load of heavy-duty battery electric vehicles. When fast charging begins, the electrolyzers are ramped down. When fast charging ends, the electrolyzers are ramped back up," Wipke said. "If done smoothly, the utility doesn't even know it's happening."

NREL Researchers Rishabh Jain, Kazunori Nagasawa, and Jen Kurtz are working on how grid integration of electrolyzers—devices that use electricity to break water into hydrogen and oxygen—could offset the grid impacts of extreme fast-charging. Credit: National Renewable Energy Laboratory
As electrolyzers harness the cheap electrons from off-demand periods, a significant amount of hydrogen can be produced on site. That creates a natural energy pathway from discount electricity into a fuel. It is no wonder, then, that several well-known transportation and fuel companies have recently initiated a multimillion-dollar partnership with NREL to advance heavy-duty hydrogen vehicle technologies.

"The logistics of expanding electric charging infrastructure from 50 kW for a single demonstration battery electric truck to 5,000 kW for a fleet of 100 could present challenges," Wipke said. "Hydrogen scales very nicely; you're basically bringing hydrogen to a fueling station or producing it on site, but either way the hydrogen fueling events are decoupled in time from hydrogen production, providing benefits to the grid."

The long driving range and fast refuel times—including a DOE target of achieving 10-minutes refuel for a truck—have already made hydrogen the standout solution for applications in warehouse forklifts. Further, NREL is finding that distributed electrolyzers can simultaneously produce hydrogen and improve voltage conditions, which can add much-needed stability to a grid that is accommodating more energy from variable resources.

Those examples that co-optimize mobility with the grid, using diverse technologies, are encouraging NREL and its partners to pursue a new scale of systems integration. Several forward-thinking projects are reimagining urban mobility as a mix of energy solutions that integrate the relative strengths of transportation technologies, which complement each other to fill important gaps in grid reliability.


The Future of Urban Mobility
What will electrified transportation look like at high penetrations? A few NREL projects offer some perspective. Among the most experimental, NREL is helping the city of Denver develop a smart community, integrated with electrified mobility and featuring automated charging and vehicle dispatch.

On another path to advanced mobility, Los Angeles has embarked on a plan to modernize its electricity system infrastructure, reflecting California EV grid stability goals—aiming for a 100% renewable energy supply by 2045, along with aggressive electrification targets for buildings and vehicles. Through the Los Angeles 100% Renewable Energy Study, the city is currently working with NREL to assess the full-scale impacts of the transition in a detailed analysis that integrates diverse capabilities across the laboratory.

The transition would include the Port of Long Beach, the busiest container port in the United States.

At the port, NREL is applying the same sort of scenario forecasting and controls evaluation as other projects, in order to find the optimal mix of technologies that can be integrated for both grid stability and a reliable quality of service: a mix of hydrogen fuel-cell and battery EVs, battery storage systems, on-site renewable generation, and extreme coordination among everything.

"Hydrogen at ports makes sense for the same reason as trucks: Marine applications have big power and energy demands," Wipke said. "But it's really the synergies between diverse technologies—the existing infrastructure for EVs and the flexibility of bulk battery systems—that will truly make the transition to high renewable energy possible."

Like the Port of Long Beach, transportation hubs across the nation are adapting to a complex environment of new mobility solutions. Airports and public transit stations involve the movement of passengers, goods, and services at a volume exceeding anywhere else. With the transition to digitally connected electric mobility changing how airports plan for the future, NREL projects such as Athena are using the power of high-performance computing to demonstrate how these hubs can maximize the value of passenger and freight mobility per unit of energy, time, and/or cost.

The growth in complexity for transportation hubs has just begun, however. Looking ahead, fleets of ride-sharing EVs, automated vehicles, and automated ride-sharing EV fleets could present the largest effort to manage mobility yet.


A Self-Driving Power Grid
To understand the full impact of future mobility-service providers, NREL developed the HIVE (Highly Integrated Vehicle Ecosystem) simulation framework. HIVE combines factors related to serving mobility needs and grid operations—such as a customer's willingness to carpool or delay travel, and potentially time-variable costs of recharging—and simulates the outcome in an integrated environment.

"Our question is, how do you optimize the management of a fleet whose primary purpose is to provide rides and improve that fleet's dispatch and charging?" said Eric Wood, an NREL vehicle systems engineer.

HIVE was developed as part of NREL's Autonomous Energy Systems research to optimize the control of automated vehicle fleets. That is, optimized routing and dispatch of automated electric vehicles.

The project imagines how price signals could influence dispatch algorithms. Consider one customer booking a commute through a ride-hailing app. Out of the fleet of vehicles nearby—variously charged and continually changing locations—which one should pick up the customer?

Now consider the movements of thousands of passengers in a city and thousands of vehicles providing transportation services. Among the number of agents, the moment-to-moment change in energy supply and demand, and the broad diversity in vendor technologies, "we're playing with a lot of parameters," Wood said.

But cutting through all the complexity, and in the midst of massive simulations, the end goal for vehicle-to-grid integration is consistent:

"The motivation for our work is that there are forecasts for significant load on the grid from the electrification of transportation," Wood said. "We want to ensure that this load is safely and effectively integrated, while meeting the expectations and needs of passengers."

True Replacement without Caveats

Electric vehicles are not necessarily helpful to the grid, but they can be. As EVs become established in the transportation sector, NREL is studying how to even out any bumps that electrified mobility could cause on the grid and advance any benefits to commuters or industry.

"It all comes down to load flexibility," Meintz said. "We're trying to decide how to optimally dispatch vehicle charging to meet quality-of-service considerations, while also minimizing charging costs."

Climate Solution: Use Carbon Dioxide to Generate Electricity

Methane Hydrate CO2 Sequestration uses carbon capture and nitrogen injection to swap gases in seafloor hydrates along the Gulf of Mexico, releasing methane for electricity while storing CO2, according to new simulation research.

 

Key Points

A method injecting CO2 and nitrogen into hydrates to store CO2 while releasing methane for power.

✅ Nitrogen aids CO2-methane swap in hydrate cages, speeding sequestration

✅ Gulf Coast proximity to emitters lowers transport and power costs

✅ Revenue from methane electricity could offset carbon capture

 

The world is quickly realizing it may need to actively pull carbon dioxide out of the atmosphere to stave off the ill effects of climate change. Scientists and engineers have proposed various carbon capture techniques, but most would be extremely expensive—without generating any revenue. No one wants to foot the bill.

One method explored in the past decade might now be a step closer to becoming practical, as a result of a new computer simulation study. The process would involve pumping airborne CO2 down into methane hydrates—large deposits of icy water and methane right under the seafloor, beneath water 500 to 1,000 feet deep—where the gas would be permanently stored, or sequestered. The incoming CO2 would push out the methane, which would be piped to the surface and burned to generate electricity, whether sold locally or via exporters like Hydro-Que9bec to help defray costs, to power the sequestration operation or to bring in revenue to pay for it.

Many methane hydrate deposits exist along the Gulf of Mexico shore and other coastlines. Large power plants and industrial facilities that emit CO2 also line the Gulf Coast, where EPA power plant rules could shape deployment, so one option would be to capture the gas directly from nearby smokestacks, keeping it out of the atmosphere to begin with. And the plants and industries themselves could provide a ready market for the electricity generated.

A methane hydrate is a deposit of frozen, latticelike water molecules. The loose network has many empty, molecular-size pores, or “cages,” that can trap methane molecules rising through cracks in the rock below. The computer simulation shows that pushing out the methane with CO2 is greatly enhanced if a high concentration of nitrogen is also injected, and that the gas swap is a two-step process. (Nitrogen is readily available anywhere, because it makes up 78 percent of the earth’s atmosphere.) In one step the nitrogen enters the cages; this destabilizes the trapped methane, which escapes the cages. In a separate step, the nitrogen helps CO2 crystallize in the emptied cages. The disturbed system “tries to reach a new equilibrium; the balance goes to more CO2 and less methane,” says Kris Darnell, who led the study, published June 27 in the journal Water Resources Research. Darnell recently joined the petroleum engineering software company Novi Labs as a data scientist, after receiving his Ph.D. in geoscience from the University of Texas, where the study was done.

A group of labs, universities and companies had tested the technique in a limited feasibility trial in 2012 on Alaska’s North Slope, where methane hydrates form in sandstone under deep permafrost. They sent CO2 and nitrogen down a pipe into the hydrate. Some CO2 ended up being stored, and some methane was released up the same pipe. That is as far as the experiment was intended to go. “It’s good that Kris [Darnell] could make headway” from that experience, says Ray Boswell at the U.S. Department of Energy’s National Energy Technology Laboratory, who was one of the Alaska experiment leaders but was not involved in the new study. The new simulation also showed that the swap of CO2 for methane is likely to be much more extensive—and to happen quicker—if CO2 enters at one end of a hydrate deposit and methane is collected at a distant end.

The technique is somewhat similar in concept to one investigated in the early 2010s by Steven Bryant and others at the University of Texas. In addition to numerous methane hydrate deposits, the Gulf Coast has large pools of hot, salty brine in sedimentary rock under the coastline. In this system, pumps would send CO2 down into one end of a deposit, which would force brine into a pipe that is placed at the other end and leads back to the surface. There the hot brine would flow through a heat exchanger, where heat could be extracted and used for industrial processes or to generate electricity, supporting projects such as electrified LNG in some markets. The upwelling brine also contains some methane that could be siphoned off and burned. The CO2 dissolves into the underground brine, becomes dense and sinks further belowground, where it theoretically remains.

Either system faces big practical challenges, and building shared CO2 storage hubs to aggregate captured gas is still evolving. One is creating a concentrated flow of CO2; the gas makes up only .04 percent of air, and roughly 10 percent of the smokestack emission from a typical power plant or industrial facility. If an efficient methane hydrate or brine system requires an input that is 90 percent CO2, for example, concentrating the gas will require an enormous amount of energy—making the process very expensive. “But if you only need a 50 percent concentration, that could be more attractive,” says Bryant, who is now a professor of chemical and petroleum engineering at the University of Calgary. “You have to reduce the [CO2] capture cost.”

Another major challenge for the methane hydrate approach is how to collect the freed methane, which could simply seep out of the deposit through numerous cracks and in all directions. “What kind of well [and pipe] structure would you use to grab it?” Bryant asks.

Given these realities, there is little economic incentive today to use methane hydrates for sequestering CO2. But as concentrations rise in the atmosphere and the planet warms further, and as calls for an electric planet intensify, systems that could capture the gas and also provide energy or revenue to run the process might become more viable than techniques that simply pull CO2 from the air and lock it away, offering nothing in return.

Quebec authorizes nearly 1,000 megawatts of electricity for 11 industrial projects

Quebec Large-Scale Power Connections allocate 956 MW via Hydro-Québec to battery, bioenergy, and green hydrogen projects, including Northvolt and data centers, advancing grid capacity, industrial electrification, and Quebec's energy transition.

 

Key Points

Allocations of 956 MW via Hydro-Québec to projects in batteries, bioenergy, and green hydrogen across Quebec.

✅ 11 projects approved, totaling 956 MW across Quebec

✅ Focus: batteries, bioenergy, green hydrogen, data centers

✅ Selection weighed grid impact, economics, environmental criteria

 

The Quebec government has unveiled the list of 11 companies whose projects were given the go-ahead for large-scale power connections of 5 megawatts or more, for a total of 956 MW, even as planned exports to New York continue to factor into supply.

Five of the selected projects relate to the battery sector, reflecting EV battery investments by Canada and Quebec, and two to the bioenergy sector.

TES Canada's plan to build a green hydrogen production plant in Shawinigan, announced on Friday, is on the list.

Hydro-Québec will also supply 5 MW or more to the future Northvolt battery plant at its facilities in Saint-Basile-le-Grand and McMasterville.

Other industrial projects selected are those of Air Liquide Canada, Ford-Ecopro CAM Canada S.E.C, Nouveau monde Graphite and Volta Energy Solutions Canada.

Bioenergy projects include Greenfield Global Québec, in Varennes, and WM Québec, in Sainte-Sophie.

There's also Duravit Canada's manufacturing project in Matane, Quebec Iron Ore's green steel project in Fermont, Côte-Nord, and Vantage Data Centers CanadaQC4's data center project in Pointe-Claire.

All projects were selected las August "according to defined analysis criteria, such as technical connection capacities and impact on the Quebec power grid operations, economic and regional development spinoffs, environmental and social impact, as well as consistency with government orientations," states the press release from the office of Pierre Fitzgibbon, Quebec's Economy, Innovation and Energy Minister.

"With energy balances tightening and the electrification of our economy on the rise, we need to choose the most promising projects and allocate available electricity wisely," said Fitzgibbon.

Cross-border capacity expansions, including the Maine transmission corridor now approved, are also shaping regional power flows.

"These 11 projects will accelerate the energy transition, while creating significant economic spinoffs throughout Quebec."

The government is continuing its analysis of other energy-intensive industrial projects to help make the transition to a greener economy, even as experts question Quebec's EV strategy in policy circles, until March 31.

Electricity Shut-Offs in a Pandemic: How COVID-19 Leads to Energy Insecurity, Burdensome Bills

COVID-19 Energy Burden drives higher electricity bills as income falls, intensifying energy poverty, utility shut-offs, and affordability risks for low-income households; policy moratoriums, bill relief, and efficiency upgrades are vital responses.

 

Key Points

The COVID-19 energy burden is the rising share of income spent on energy as bills increase and earnings decline.

✅ Rising home demand and lost wages increase energy cost share.

✅ Mandated shut-off moratoriums and reconnections protect health.

✅ Fund assistance, efficiency, and solar for LMI households.

 

I have asthma. It’s a private piece of medical information that I don’t normally share with people, but it makes the potential risks associated with exposure to the coronavirus all the more dangerous for me. But I’m not alone. 107 million people in the U.S. have pre-existing medical conditions like asthma and heart disease; the same pre-existing conditions that elevate their risk of facing a life-threatening situation were we to contract COVID-19. There are, however, tens of millions more house-bound Americans with a condition that is likely to be exacerbated by COVID-19: The energy burden.

The energy burden is a different kind of pre-existing condition:
In the last four weeks, 22 million people filed for unemployment. Millions of people will not have steady income (or the healthcare tied to it) to pay rent and utility bills for the foreseeable future which means that thousands, possibly millions of home-bound Americans will struggle to pay for energy.

Your energy burden is the amount of your monthly income that goes to paying for energy, like your monthly electric bill. So, when household energy use increases or income decreases, your energy burden rises. The energy burden is not a symptom of the pandemic and the economic downturn; it is more like a pre-existing condition for many Americans.

Before the coronavirus outbreak, I shared a few maps that showed how expensive electricity is for some. The energy burden in most pronounced in places already struggling economically, like in Appalachia, where residents in some counties must put more than 30 percent of their income toward their electric bills, and in the Midwest where states such as Michigan have some families spending more than 1/5 of their income on energy bills. The tragic facts are that US families living below the poverty line are far more likely to also be suffering from their energy burden.

But like other pre-existing conditions, the impacts of the coronavirus pandemic are exacerbating the underlying problems afflicting communities across the country.

Critical responses to minimize the spread of COVID-19 are social distancing, washing hands frequently, covering our faces with masks and staying at home. More time at home for most will drive up energy bills, and not by a little. Estimates on how much electricity demand during COVID-19 will increase vary but I’ve seen estimates as high as a 20% increase on average. For some families that’s a bag of groceries or a refill on prescription medication.

What happens when the power gets turned off?
Under normal conditions, if you cannot pay your electric bill your electricity can get turned off. This can have devastating consequences. Most states have protections for health and medical reasons and some states have protections during extreme heat or cold weather. But enforcement of those protections can vary by utility service area and place unnecessary burdens on the customer.

UCS
Only Florida has no protections of any kind against utility shut-offs when health or medical reasons would merit protection against it. However, when it comes to protection against extreme heat, only a few states have mandatory protections based on temperature thresholds.

The NAACP has also pointed out that utilities have unceremoniously disconnected the power of millions of people, disproportionally African-American and Latinx households.

April tends to be a mild month for most of the country, but the South already had its first heat wave at the end of March. If this pandemic lasts into the summer, utility disconnects could become deadly, and efforts to prevent summer power outages will be even more critical to public health. In the summer, during extreme summer heat families can’t turn off the A/C and go to the movies if we are following public health measures and sheltering in place. Lots of families that don’t have or can’t afford to run A/C would otherwise gather at local community pools, beaches, or in cooling centers, but with parks, pools and community groups closed to prevent the virus’s spread, what will happen to these families in July or August?

But we won’t have to wait till the summer to see how families will be hard hit by falling behind on bills and losing power. Here are a few ways electricity disconnection policies cause people harm during the pandemic:

Loss of electricity during the COVID-19 pandemic means families will lose their ability to refrigerate essential food supplies.
Child abuse guidance discusses how unsanitary household conditions are a contributing factor to child protective services involvement. Unsanitary household conditions can include, for example, rotting food (which might happen if electricity is cut off).

HUD’s handbook on federally subsidized housing includes a chapter on termination, which says that lease agreements can be terminated for repeated minor infractions including failing to pay utilities.
Airway machines used to treat respiratory ailments—pre-existing conditions in this pandemic—will not work. Our elderly neighbors in particular might rely on medicine that requires refrigeration or medical equipment that requires electricity. They too have fallen victim to utility shut-offs even during the pandemic.

Empowering solutions are available today

Decisionmakers seeking solutions can look to implement utility shut off moratoriums as a good start. Good news is that many utilities have voluntarily taken action to that effect, and New Jersey and New York have suspended shut-offs, one of the best trackers on who is taking what action has been assembled by Energy Policy Institute.

But voluntary actions do not always provide comprehensive protection, and they certainly have not been universally adopted across the country. Some utilities are waiving fees as relief measures, and some moratoriums only apply to customers directly affected by COVID-19, which will place additional onerous red tape on households that are stricken and perhaps unable to access testing. Others might only be an extension of standard medical shut off protections. Moratoriums put in place by voluntary action can also be revoked or lifted by voluntary action, which does not provide any sense of certainty to people struggling to make ends meet.

This is why the US needs mandatory moratoriums on all utility disconnections. These normally would be rendered at the state level, either by a regulatory commission, legislative act, or even an emergency executive order. But the inconsistent leadership among states in response to the COVID-19 crisis suggests that Congressional action is needed to ensure that all vulnerable utility customers are protected. That’s exactly what a coalition of organizations, including UCS, is calling for in future federal aid legislation. UCS has called for a national moratorium on utility shut-offs.

And let’s be clear, preventing new shut-offs isn’t enough. Cutting power off at residence during a pandemic is not good public policy. People who are without electricity should have it restored so residents can safely shelter in place and help flatten the curve. So far, only Colorado and Wisconsin’s leadership has taken this option.

Addressing the root causes of energy poverty
Preventing shut-offs is a good first step, but the increased bill charges will nevertheless place greater economic pressure on an incalculable number of families. Addressing the root of the problem (energy affordability) must be prioritized when we begin to recover from the health and economic ramifications of the COVID-19 pandemic.

One way policymakers can do that is to forgive outstanding balances on utility bills, perhaps with an eligibility cap based on income. Additional funds could be made available to those who are still struggling to pay their bills via capping bills, waiving late payment fees, automating payment plans or other protective measures that rightfully place consumers (particularly vulnerable consumers) at the center of any energy-related COVID-19 response. Low-and-moderate-income energy efficiency and solar programs should be funded as much as practically possible.

New infrastructure, particularly new construction that is slated for public housing, subsidized housing, or housing specifically marketed for low- and moderate-income families, should include smart thermostats, better insulation, and energy-efficient appliances.

Implementing these solutions may seem daunting, let us not forget that one of the best ways to ease people’s energy burden is to keep a utility’s overall energy costs low. That means state utility commissions must be vigilant in utility rate cases and fuel recovery cost dockets to protect people facing unfathomable economic pressures. Unscrupulous utilities have been known to hide unnecessary costs in our energy bills. Commissions and their staff are overwhelmed at this time, but they should be applying extra scrutiny during proceedings when utilities are recovering costs associated with delivering energy.

What might a utility try to get past the commission?
Well, residential demand is up, so for many people, bills will increase. However, wholesale electricity rates are low right now, in some cases at all-time lows. Why? Because industrial and commercial demand reductions (from social distancing at home) have more than offset residential demand increases. Overall US electricity demand is flat or declining, and supply/demand economics predicts that when demand decreases, prices decrease.

At the same time, natural gas prices have set record lows each month of this year and that’s a trend that is expected to hold true for a while.

Low demand plus low gas prices mean wholesale market prices are incredibly low. Utilities should be taking advantage of low market prices to ensure that they deliver electricity to customers at as low a cost as possible. Utilities must also NOT over-run coal plants uneconomically or lean on aging capacity despite disruptions in coal and nuclear that can invite brownouts because that will not only needlessly cost customers more, but it will also increase air pollution which will exacerbate respiratory issues and susceptibility to COVID-19, according to a recent study published by Harvard.
