General Motors Corp. has joined with more than 30 utility companies across the U.S. to help work out electricity issues that will crop up when it rolls out new electric vehicles in a little more than two years.

The Detroit automaker said the partnership, which includes the Electric Vehicle Research Institute and large utilities such as Southern California Edison and Duke Energy Corp., will deal with issues from tax incentives for the vehicles to where and when they can be plugged in for recharging.

GM is working to bring the Chevrolet Volt rechargeable car to showrooms in late 2010. It's being designed to run on an electric motor powered by lithium-ion batteries. When fully charged, it will be able to go 40 miles on battery power. For longer trips, a small internal combustion engine will recharge the batteries to keep the Volt moving.

"This vehicle is real. It's coming into production," said Britta Gross, a GM engineer who is helping to build the infrastructure for cars of the future. "We know that when the vehicle is in the showroom and ready for sale, it's got to work seamlessly with the infrastructure. It's the whole picture. We've got to make sure the infrastructure is ready."

GM and the utilities planned to announcement the partnership at a conference on plug-in hybrid electric vehicles in San Jose.

The consortium will work on everything from policy issues including tax incentives for purchasing what is likely to be an expensive car to whether the electric generation system can handle the increased power demand.

The cars will have to be designed so recharging them can be timed to low-demand periods for electricity, Gross said. The speed of the recharging, voltage, amperage and other issues all have to be worked out, she said. The group also will address issues such as how apartment dwellers can charge their cars and where the vehicles will be charged at work or on trips - and who pays for the electricity, Gross said.

"We want this to sell in just huge volumes, so we want to get it right," she said.

A team of GM engineers and designers is working on the Volt, hoping to be the leader in plug-in electric vehicles. Other automakers, including Toyota Motor Corp., also are working on similar vehicles.

GM already is showing Volt prototypes to focus groups and is testing a new generation of batteries that can carry enough juice to run the vehicles 40 miles. It is being designed so it can be recharged from a conventional household electrical outlet.

But the car will be priced anywhere from $30,000 to $40,000, far more expensive than most conventional cars.

The group, Gross said, likely will seek government tax incentives for buyers because of the benefits the car brings to society, such as lowered greenhouse gas emissions and reduced dependence on foreign oil.

"The price to the consumer has got to be affordable," she said.

Utilities, she said, can benefit from the cars because they will sell more electricity during off-peak hours when they have idle generating capacity.

But automakers and utilities will have to work out ways to decide how to stagger recharging so local substations do not become overloaded, Gross said.

The Volt likely will need about 8 kilowatt-hours of energy to recharge, Gross said. The average U.S. utility charges about 10 cents per kilowatt-hour, so it would cost the consumer about 80 cents to go the 40 miles, she said.

$453M Manitoba Hydro line to Minnesota could face delay after energy board recommendation

Manitoba-Minnesota Transmission Project faces NEB certificate review, with public hearings, Indigenous consultation, and cross-border approval weighing permit vs certificate timelines, potential land expropriation, and Hydro's 2020 in-service date for the 308-MW intertie.

 

Key Points

A cross-border hydro line linking Manitoba and Minnesota, now under NEB review through a permit or certificate process.

✅ NEB recommends certificate with public hearings and cabinet approval

✅ Stakeholders cite land, health, and economic impacts along route

✅ Hydro targets May-June 2020 in-service despite review

 

A recommendation from the National Energy Board could push back the construction start date of a $453-million hydroelectric transmission line from Manitoba to Minnesota.

In a letter to federal Natural Resources Minister Jim Carr, the regulatory agency recommends using a "certificate" approval process, which could take more time than the simpler "permit" process Manitoba Hydro favours.

The certificate process involves public hearings, reflecting First Nations intervention seen in other power-line debates, to weigh the merits of the project, which would then go to the federal cabinet for approval.

The NEB says this process would allow for more procedural flexibility and "address Aboriginal concerns that may arise in the circumstances of this process."

The Manitoba-Minnesota Transmission Project would provide the final link in a chain that brings hydroelectricity from generating stations in northern Manitoba, through the Bipole III transmission line and, like the New England Clean Power Link project, across the U.S. border as part of a 308-megawatt deal with the Green Bay-based Wisconsin Public Service.

When Hydro filed its application in December 2016, it had expected to have approval by the end of August 2017 and to begin construction on the line in mid-December, in order to have the line in operation by May or June 2020.  

Groups representing stakeholders along the proposed route of the transmission line had mixed reactions to the energy board's recommendation.

A lawyer representing a coalition of more than 120 landowners in the Rural Municipality of Taché and around La Broquerie, Man., welcomed the opportunity to have a more "fulsome" discussion about the project.

"I think it's a positive step. As people become more familiar with the project, the deficiencies with it become more obvious," said Kevin Toyne, who represents the Southeast Stakeholders Coalition.

Toyne said some coalition members are worried that Hydro will forcibly expropriate land in order to build the line, while others are worried about potential economic and health impacts of having the line so close to their homes. They have proposed moving the line farther east.

When the Clean Environment Commission — an arm's-length provincial government agency — held public hearings on the proposed route earlier this year, the coalition brought their concerns forward, echoing Site C opposition voiced by northerners, but Toyne says both the commission and Hydro ignored them.

Hydro still aiming for 2020 in-service date

The Manitoba Métis Federation also participated in those public hearings. MMF president David Chartrand worries about the impact a possible delay, as seen with the Site C work halt tied to treaty rights, could have on revenue from sales of hydroelectric power to the U.S.

"I know that a lot of money, billions have been invested on this line. And if the connection line is not done, then of course this will be sitting here, not gaining any revenue, which will affect every Métis in this province, given our Hydro bill's going to go up," Chartrand said.The NEB letter to Minister Carr requests that he "determine this matter in an expedited manner."

Manitoba Hydro spokesperson Bruce Owen said in an email that the Crown corporation will participate in whatever process, permit or certificate, the NEB takes.

"Manitoba Hydro does not have any information at this point in time that would change the estimated in-service date (May-June 2020) for the Manitoba-Minnesota Transmission Project," he said.

The federal government "is currently reviewing the NEB's recommendation to designate the project as subject to a certificate, which would result in public hearings," said Alexandre Deslongchamps, a spokesperson for Carr.

"Under the National Energy Board Act, an international power line requires either the approval by the NEB through a permit or approval by the Government of Canada by a certificate. Both must be issued by the NEB," he wrote in an email to CBC News.

By law, the certificate process is not to take longer than 15 months.

Should California Fund Biofuels or Electric Vehicles?

California Biofuels vs EV Subsidies examines tradeoffs in decarbonization, greenhouse gas reductions, clean energy deployment, charging infrastructure, energy security, lifecycle emissions, and transportation sector policy to meet climate goals and accelerate sustainable mobility.

 

Key Points

Policy tradeoffs weighing biofuels and EVs to cut GHGs, boost energy security, and advance clean transportation.

✅ Near-term blending cuts emissions from existing fleets

✅ EVs scale with a cleaner grid and charging buildout

✅ Lifecycle impacts and costs guide optimal subsidy mix

 

California is at the forefront of the transition to a greener economy, driven by its ambitious goals to reduce greenhouse gas emissions and combat climate change. As part of its strategy, the state is grappling with the question of whether it should subsidize out-of-state biofuels or in-state electric vehicles (EVs) to meet these goals. Both options come with their own sets of benefits and challenges, and the decision carries significant implications for the state’s environmental, economic, and energy landscapes.

The Case for Biofuels

Biofuels have long been promoted as a cleaner alternative to traditional fossil fuels like gasoline and diesel. They are made from organic materials such as agricultural crops, algae, and waste, which means they can potentially reduce carbon emissions in comparison to petroleum-based fuels. In the context of California, biofuels—particularly ethanol and biodiesel—are viewed as a way to decarbonize the transportation sector, which is one of the state’s largest sources of greenhouse gas emissions.

Subsidizing out-of-state biofuels can help California reduce its reliance on imported oil while promoting the development of biofuel industries in other states. This approach may have immediate benefits, as biofuels are widely available and can be blended with conventional fuels to lower carbon emissions right away. It also allows the state to diversify its energy sources, improving energy security by reducing dependency on oil imports.

Moreover, biofuels can be produced in many regions across the United States, including rural areas. By subsidizing out-of-state biofuels, California could foster economic development in these regions, creating jobs and stimulating agricultural innovation. This approach could also support farmers who grow the feedstock for biofuel production, boosting the agricultural economy in the U.S.

However, there are drawbacks. The environmental benefits of biofuels are often debated. Critics argue that the production of biofuels—particularly those made from food crops like corn—can contribute to deforestation, water pollution, and increased food prices. Additionally, biofuels are not a silver bullet in the fight against climate change, as their production and combustion still release greenhouse gases. When considering whether to subsidize biofuels, California must also account for the full lifecycle emissions associated with their production and use.

The Case for Electric Vehicles

In contrast to biofuels, electric vehicles (EVs) offer a more direct pathway to reducing emissions from transportation. EVs are powered by electricity, and when coupled with renewable energy sources like solar or wind power, they can provide a nearly zero-emission solution for personal and commercial transportation. California has already invested heavily in EV infrastructure, including expanding its network of charging stations and exploring how EVs can support grid stability through vehicle-to-grid approaches, and offering incentives for consumers to purchase EVs.

Subsidizing in-state EVs could stimulate job creation and innovation within California's thriving clean-tech industry, with other states such as New Mexico projecting substantial economic gains from transportation electrification, and the state has already become a hub for electric vehicle manufacturers, including Tesla, Rivian, and several battery manufacturers. Supporting the EV industry could further strengthen California’s position as a global leader in green technology, attracting investment and fostering growth in related sectors such as battery manufacturing, renewable energy, and smart grid technology.

Additionally, the environmental benefits of EVs are substantial. As the electric grid becomes cleaner with an increasing share of renewable energy, EVs will become even greener, with lower lifecycle emissions than biofuels. By prioritizing EVs, California could further reduce its carbon footprint while also achieving its long-term climate goals, including reaching carbon neutrality by 2045.

However, there are challenges. EV adoption in California remains a significant undertaking, requiring major investments in infrastructure as they challenge state power grids in the near term, technology, and consumer incentives. The cost of EVs, although decreasing, still remains a barrier for many consumers. Additionally, there are concerns about the environmental impact of lithium mining, which is essential for EV batteries. While renewable energy is expanding, California’s grid is still reliant on fossil fuels to some degree, and in other jurisdictions such as Canada's 2019 electricity mix fossil generation remains significant, meaning that the full emissions benefit of EVs is not realized until the grid is entirely powered by clean energy.

A Balancing Act

The debate between subsidizing out-of-state biofuels and in-state electric vehicles is ultimately a question of how best to allocate California’s resources to meet its climate and economic goals. Biofuels may offer a quicker fix for reducing emissions from existing vehicles, but their long-term benefits are more limited compared to the transformative potential of electric vehicles, even as some analysts warn of policy pitfalls that could complicate the transition.

However, biofuels still have a role to play in decarbonizing hard-to-abate sectors like aviation and heavy-duty transportation, where electrification may not be as feasible in the near future. Thus, a mixed strategy that includes both subsidies for EVs and biofuels may be the most effective approach.

Ultimately, California’s decision will likely depend on a combination of factors, including technological advancements, 2021 electricity lessons, and the pace of renewable energy deployment, and the state’s ability to balance short-term needs with long-term environmental goals. The road ahead is not easy, but California's leadership in clean energy will be crucial in shaping the nation’s response to climate change.

U.S. Department of Energy Announces $110M for Carbon Capture, Utilization, and Storage

DOE CCUS Funding advances carbon capture, utilization, and storage with FEED studies, regional deployment, and CarbonSAFE site characterization, leveraging 45Q tax credits to scale commercial CO2 reduction across fossil energy sectors.

 

Key Points

DOE CCUS Funding are federal FOAs for commercial carbon capture, storage, and utilization via FEED and CarbonSAFE.

✅ $110M across FEED, Regional, and CarbonSAFE FOAs

✅ Supports Class VI permits, NEPA, and site characterization

✅ Enables 45Q credits and enhanced oil recovery utilization

 

The U.S. Department of Energy’s (DOE’s) Office of Fossil Energy (FE) has announced approximately $110 million in federal funding for cost-shared research and development (R&D) projects under three funding opportunity announcements (FOAs), alongside broader carbon-free electricity investments across the power sector.

Approximately $75M is for awards selected under two FOAs announced earlier this fiscal year; $35M is for a new FOA.

These FOAs further the Administration’s commitment to strengthening coal while protecting the environment. Carbon capture, utilization, and storage (CCUS) is increasingly becoming widely accepted as a viable option for fossil-based energy sources—such as coal- or gas-fired power plants under new EPA power plant rules and other industrial sources—to lower their carbon dioxide (CO2) emissions.

DOE’s program has successfully deployed various large-scale CCUS pilot and demonstration projects, and it is imperative to build upon these learnings to test, mature, and prove CCUS technologies at the commercial scale. A recent study by Science of the Total Environment found that DOE is the most productive organization in the world in the carbon capture and storage field.

“This Administration is committed to providing cost-effective technologies to advance CCUS around the world,” said Secretary Perry. “CCUS technologies are vital to ensuring the United States can continue to safely use our vast fossil energy resources, and we are proud to be a global leader in this field.”

“CCUS technologies have transformative potential,” said Assistant Secretary for Fossil Energy Steven Winberg. “Not only will these technologies allow us to utilize our fossil fuel resources in an environmentally friendly manner, but the captured CO2 can also be utilized in enhanced oil recovery and emerging CO2-to-electricity concepts, which would help us maximize our energy production.”

Under the first FOA award, Front-End Engineering Design (FEED) Studies for Carbon Capture Systems on Coal and Natural Gas Power Plants, DOE has selected nine projects to receive $55.4 million in federal funding for cost-shared R&D. The selected projects will support FEED studies for commercial-scale carbon capture systems. Find project descriptions HERE. 

Under the second FOA award, Regional Initiative to Accelerate CCUS Deployment, DOE selected four projects to receive up to $20 million in federal funding for cost-shared R&D. The projects also advance existing research and development by addressing key technical challenges; facilitating data collection, sharing, and analysis; evaluating regional infrastructure, including CO2 storage hubs and pipelines; and promoting regional technology transfer. Additionally, this new regional initiative includes newly proposed regions or advanced efforts undertaken by the previous Regional Carbon Sequestration Partnerships (RCSP) Initiative. Find project descriptions HERE. 

Elsewhere in North America, provincial efforts such as Quebec's and industry partners like Cascades are investing in energy efficiency projects to complement emissions-reduction goals.

Under the new FOA, Carbon Storage Assurance Facility Enterprise (CarbonSAFE): Site Characterization and CO2 Capture Assessment, DOE is announcing up to $35 million in federal funding for cost-shared R&D projects that will accelerate wide-scale deployment of CCUS through assessing and verifying safe and cost-effective anthropogenic CO2 commercial-scale storage sites, and carbon capture and/or purification technologies. These types of projects have the potential to take advantage of the 45Q tax credit, bolstered by historic U.S. climate legislation, which provides a tax credit for each ton of CO2 sequestered or utilized. The credit was recently increased to $35/metric ton for enhanced oil recovery and $50/metric ton for geologic storage.

Projects selected under this new FOA shall perform the following key activities: complete a detailed site characterization of a commercial-scale CO2 storage site (50 million metric tons of captured CO2 within a 30 year period); apply and obtain an underground injection control class VI permit to construct an injection well; complete a CO2capture assessment; and perform all work required to obtain a National Environmental Policy Act determination for the site.

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."

Mercury in $3 billion takeover bid for Tilt Renewables

Mercury Energy Tilt Renewables acquisition signals a trans-Tasman energy push as PowAR and Mercury split assets via a scheme of arrangement, offering $7.80 per share and a $2.96b valuation across Australia and New Zealand.

 

Key Points

A PowAR-Mercury deal to buy Tilt Renewables, splitting Australian and New Zealand assets via a court-approved scheme.

✅ $7.80 per share, valuing Tilt at $2.96b

✅ PowAR takes AU assets; Mercury gets NZ business

✅ Infratil and Mercury to vote for the scheme

 

Mercury Energy and an Australian partner appear to have won the race to buy Tilt Renewables, an Australasian wind farm developer which was spun out of TrustPower, bidding almost $3 billion, amid wider utility consolidation such as the Peterborough Distribution sale to Hydro One.

Yesterday Tilt Renewables announced that it had entered a scheme implementation agreement under which it was proposed that PowAR would acquire its Australian business and Mercury would acquire the New Zealand business, mirroring cross-border approvals where U.S. antitrust clearance shaped Hydro One's bid for Avista.

Conducted through a scheme of arrangement, Tilt shareholders will be offered $7.80 a share, valuing Tilt at $2.96b.

Yesterday morning shares in Tilt opened about 18 per cent up at $7.65, though regulatory outcomes can swing valuations as seen when Hydro One-Avista reconsideration of a U.S. order came into play.

In early December Infratil, which owns around two thirds of Tilt's shares, announced it was undertaking a review of its investment after receiving approaches, with investor sentiment sensitive to governance shifts as when Hydro One shares fell after leadership changes in Ontario.

According to a report in the Australian Financial Review, the transtasman bid beat out other parties including ASX-listed APA Group, Canadian pension fund CDPQ and Australian fund manager Infrastructure Capital Group, as Canadian investors like Ontario Teachers' Plan pursue similar infrastructure deals.

“This compelling acquisition proposal is a result of Tilt Renewables’ constant focus on delivering long-term value for shareholders and the board is pleased that, with these new owners, the transition to renewables in Australia and New Zealand will continue to accelerate,” Tilt’s chairman Bruce Harker said.

Comparable community-led clean energy partnerships, such as initiatives with British Columbia First Nations highlighted in clean-energy generation, underscore the broader momentum.

Just prior to the announcement, Tilt shares had been trading for less than $4. Such repricing reflects how utilities can face perceived uncertainties, as one investor argued too many unknowns at the time.

Mercury is already Tilt’s second largest shareholder, at just under 20 per cent. Both Infratil and Mercury have agreed to vote in favour of the scheme. The deal values Tilt’s New Zealand business at $770m, however the value of Mercury’s existing shareholding is around $585m, meaning the company will increase debt by around $185m.

✅ EU and US shift to renewables and gas, cutting emissions.

 

The world’s use of coal-fired electricity is on track for its biggest annual fall on record this year after more than four decades of near-uninterrupted growth that has stoked the global climate crisis.

Data shows that coal-fired electricity is expected to fall by 3% in 2019, or more than the combined coal generation in Germany, Spain and the UK last year and could help stall the world’s rising carbon emissions this year.

The steepest global slump on record is likely to emerge in 2019 as India’s reliance on coal power falls for the first time in at least three decades this year, and China’s coal power demand plateaus, reflecting the broader global energy transition underway.

Both developing nations are using less coal-fired electricity due to slowing economic growth in Asia as well as the rise of cleaner energy alternatives. There is also expected to be unprecedented coal declines across the EU and the US as developed economies turn to clean forms of energy such as low-cost solar power to replace ageing coal plants.

In almost 40 years the world’s annual coal generation has fallen only twice before: in 2009, in the wake of the global financial crisis, and in 2015, following a slowdown in China’s coal plants amid rising levels of deadly air pollution.

The research was undertaken by the Centre for Research on Energy and Clean Air , the Institute for Energy Economics and Financial Analysis and the UK climate thinktank Sandbag.

The researchers found that China’s coal-fired power generation was flatlining, despite an increase in the number of coal plants being built, because they were running at record low rates. China builds the equivalent of one large new coal plant every two weeks, according to the report, but its coal plants run for only 48.6% of the time, compared with a global utilisation rate of 54% on average.

The findings come after a report from Global Energy Monitor found that the number of coal-fired power plants in the world is growing, because China is building new coal plants five times faster than the rest of the world is reducing their coal-fired power capacity.

The report found that in other countries coal-fired power capacity fell by 8GW in the 18 months to June but over the same period China increased its capacity by 42.9GW.

In a paper for the industry journal Carbon Brief, the researchers said: “A 3% reduction in power sector coal use could imply zero growth in global CO2 emissions, if emissions changes in other sectors mirror those during 2018.”

However, the authors of the report have warned that despite the record coal power slump the world’s use of coal remained far too high to meet the climate goals of the Paris agreement, and some countries are still seeing increases, such as Australia’s emissions rise amid increased pollution from electricity and transport.

The US – which is backing out of the Paris agreement – has made the deepest cuts to coal power of any developed country this year by shutting coal plants down in favour of gas power and renewable energy, with utilities such as Duke Energy facing investor pressure to disclose climate plans. By the end of August the US had reduced coal by almost 14% over the year compared with the same months in 2018.

The EU reported a record slump in coal-fired electricity use in the first half of the year of almost a fifth compared with the same months last year. This trend is expected to accelerate over the second half of the year to average a 23% fall over 2019 as a whole. The EU is using less coal power in favour of gas-fired electricity – which can have roughly half the carbon footprint of coal – and renewable energy, helped by policies such as the UK carbon tax that have slashed coal-fired generation.

We will not stay quiet on the escalating climate crisis and we recognise it as the defining issue of our lifetimes. The Guardian will give global heating, wildlife extinction and pollution the urgent attention they demand. Our independence means we can interrogate inaction by those in power. It means Guardian reporting will always be driven by scientific facts, never by commercial or political interests.

We believe that the problems we face on the climate crisis are systemic and that fundamental societal change is needed. We will keep reporting on the efforts of individuals and communities around the world who are fearlessly taking a stand for future generations and the preservation of human life on earth. We want their stories to inspire hope. We will also report back on our own progress as an organisation, as we take important steps to address our impact on the environment.
