2006 Shutdown Spurs Call For Investigation of Nuclear Cybersecurity

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.

Renewables 2020 Global Status Report highlights renewable energy gaps beyond power, urging decarbonization in heating, cooling, and transport, greener COVID-19 recovery, market reforms, and rapid energy transition to cut CO2 emissions and fossil fuel dependence.

Key Points

REN21's annual report on renewable energy progress and policy gaps across power, heating, cooling, and transport.

✅ Calls for decarbonizing heating, cooling, and transport.

✅ Warns COVID-19 recovery must avoid fossil fuel lock-in.

✅ Urges market reforms to boost energy efficiency and renewables.

Growth in renewable power has been impressive over the past five years, with over 30% of global electricity now coming from renewables worldwide. But too little is happening in heating, cooling and transport. Overall, global hunger for energy keeps increasing and eats up progress, according to REN21's Renewables 2020 Global Status Report (GSR), released today. The journey towards climate disaster continues, unless we make an immediate switch to efficient and renewable energy in all sectors in the wake of the COVID-19 pandemic.

"Year after year, we report success after success in the renewable power sector. Indeed, renewable power has made fantastic progress. It beats all other fuels in growth and competitiveness. Many national and global organisations already cry victory. But our report sends a clear warning: The progress in the power sector is only a small part of the picture. And it is eaten up as the world's energy hunger continues to increase. If we do not change the entire energy system, we are deluding ourselves," says Rana Adib, REN21's Executive Director.

The report shows that in the heating, cooling and transport sectors, the barriers are still nearly the same as 10 years ago. "We must also stop heating our homes and driving our cars with fossil fuels," Adib claims.

There is no real disruption in the COVID-19 pandemic

In the wake of the extraordinary economic decline due to COVID-19, the IEA predicts energy-related CO2 emissions are expected to fall by up to 8% in 2020. But 2019 emissions were the highest ever, and the relief is only temporary. Meeting the Paris targets would require an annual decrease of at least 7.6% to be maintained over the next 10 years, and UN analysis on NDC ambition underscores the need for faster action. Says Adib: "Even if the lock-downs were to continue for a decade, the change would not be sufficient. At the current pace, with the current system and current market rules, it would take the world forever to come anywhere near a no-carbon system."

"Many recovery packages lock us into a dirty fossil fuel economy"

Recovery packages offer a once-in-a-lifetime chance to make the shift to a low-carbon economy, and green energy investments could accelerate COVID-19 recovery. But according to Adib there is a great risk for this enormous chance to be lost. "Many of these packages include ideas that will instead lock us further into a dirty fossil fuel system. Some directly promote natural gas, coal or oil. Others, though claiming a green focus, build the roof and forget the foundation," she says. "Take electric cars and hydrogen, for example. These technologies are only green if powered by renewables."

Choosing an energy system that supports job creation and social justice

The report points out that "green" recovery measures, such as investment in renewables and building efficiency, are more cost-effective than traditional stimulus measures and yield more returns. It also documents that renewables deliver on job creation, energy sovereignty, accelerated energy access in developing countries, and clean, affordable and sustainable electricity for all objectives worldwide, alongside reduced emissions and air pollution.

"Renewables are now more cost-effective than ever, and recent IRENA analysis shows their potential to decarbonise the energy sector, providing an opportunity to prioritize clean economic recovery packages and bring the world closer to meeting the Paris Agreement Goals. Renewables are a key pillar of a healthy, safe and green COVID-19 recovery that leaves no one behind," said Inger Andersen, Executive Director of the UN Environment Programme (UNEP). "By putting energy transition at the core of economic recovery, countries can reap multiple benefits, from improved air quality to employment generation."

This contrasts with the true cost of fossil fuels, estimated to be USD 5.2 trillion if costs of negative impacts such as air pollution, effects of climate change, and traffic congestion are counted.

Renewable energy systems support energy sovereignty and democracy, empowering citizens and communities, instead of big fossil fuel producers and consumers. "When spending stimulus money, we have to decide: Do we want an energy system that serves some or a system that serves many?", says Adib. "But it's not only about money. We must end any kind of support to the fossil economy, particularly when it comes to heating, cooling and transport. Governments need to radically change the market conditions and rules and demonstrate the same leadership as during the COVID-19 pandemic."

The report finds:

Total final energy demand continues to be on the rise (1.4% annually from 2013 to 2018). Despite significant progress in renewable power generation, the share of renewables in total final energy demand barely increased (9.6% in 2013 to 11% in 2018). Compared to the power sector, the heating, cooling and transport sectors lag far behind (renewable energy share in power, 26%, heating and cooling, 10%, transport, 3%).

Today's progress is largely the result of policies and regulations initiated years ago and focus on the power sector. Major barriers seen in heating, cooling and transport are still almost the same a decade on. Policies are needed to create the right market conditions.

The renewable energy sector employed around 11 million people worldwide in 2018

In 2019, the private sector signed power purchase agreements (PPAs) for a record growth of over 43% from 2018 to 2019 in new renewable power capacity.

The global climate strikes have reached unprecedented levels with millions of people across 150 countries. They have pushed governments to step up climate ambitions. As of April 2020, 1490 jurisdictions - spanning 29 countries and covering 822 million citizens - had issued "climate emergency" declarations, many of which include plans and targets for more renewable-based energy systems.

While some countries are phasing out coal, examples such as Europe's green surge show how renewables can soar as emissions fall, yet others continued to invest in new coal-fired power plants. In addition, funding from private banks for fossil fuel projects has increased each year since the signing of the Paris Agreement, totaling USD 2.7 trillion over the last three years.

"It is clear, renewable power has become mainstream and that is great to see. But the progress in this one sector should not lead us to believe that renewables are a guaranteed success. Governments need to take action beyond economic recovery packages. They also need to create the rules and the environment to switch to an efficient and renewables-based energy system, and action toward 100% renewables is urgently needed worldwide. Globally. Now." concludes Arthouros Zervos, President of REN21.

Spain Wind Turbine Factory Shutdowns disrupt manufacturing as Vestas, Siemens Gamesa, and Nordex halt Spanish plants amid COVID-19 lockdowns, straining supply chains and renewables projects across Europe, with partial operations and maintenance continuing.

Key Points

COVID-19 lockdowns pause Spanish wind factories by Vestas, Siemens Gamesa, and Nordex, disrupting supply chains.

✅ Vestas, Siemens Gamesa, Nordex halt Spanish manufacturing

✅ Service and maintenance continue under safety protocols

✅ Supply chain and project timelines face delays in Europe

Europe’s largest wind turbine makers on Wednesday said they had shut down more factories in Spain, a major hub for the continent’s renewables sector, in response to an almost total lockdown in the country to contain the coronavirus outbreak as the Covid-19 crisis disrupts the sector.

Denmark’s Vestas, the world No.1, has suspended production at its two Spanish plants, a spokesman told Reuters, adding that its service and maintenance business was still working. Vestas has also paused manufacturing and construction in India, which is under a nationwide lockdown too, he said, and similar disruptions could stall U.S. utility solar projects this year.

Top rival Siemens Gamesa, known for its offshore wind turbine lineup, suspended production at six Spanish factories on Monday, bringing total closures there to eight, a spokeswoman said.

Four components factories are still partially up and running, at Reinosa on the north coast, Cuenca near Madrid, Mungia and Siguiero, she added.

Germany’s Nordex, the No.8 globally which is 36% owned by Spain’s Acciona, has now shuttered all of its production in Spain, even as new projects like Enel’s 90MW build move ahead, including two nacelle casing factories in Barasoain and Vall d’Uixo, as well as a rotor blade site in Lumbier.

“Production is no longer active,” a spokeswoman said in response to a Reuters query.

The new closures take the number of idled wind power factories on the continent to 19, all in Spain and Italy, the European countries worst hit by the pandemic, with investments at risk across the sector.

Spain is second only to Italy in terms of numbers of coronavirus-related fatalities and restrictions have become even stricter in the country’s third week of lockdown at a time when renewables surpassed fossil fuels for the first time in Europe.

“Some factories have temporarily paused activity as a precautionary step to strengthen sanitary measures within the sites and guarantee full compliance with government recommendations,” industry association WindEurope said, noting that wind power grows in some markets despite the pandemic.

Hornsea One Offshore Wind Farm delivers first power to the UK grid, scaling renewable energy with 1.2GW capacity, giant offshore turbines, and Yorkshire coast infrastructure to replace delayed nuclear and cut fossil fuel emissions.

Key Points

Hornsea One Offshore Wind Farm is a 1.2GW UK project delivering offshore renewable power to about 1 million homes.

✅ 174 turbines over 407 km2; Siemens Gamesa supply chain in the UK

✅ 1.2GW capacity can power ~1m homes; phases scale with 10MW+ turbines

✅ Supports UK grid, replaces delayed nuclear, cuts fossil generation

An offshore windfarm on the Yorkshire coast that will dwarf the world’s largest when completed is to supply its first power to the UK electricity grid this week, mirroring advances in tidal electricity projects delivering to the grid as well.

The Danish developer Ørsted, which has installed the first of 174 turbines at Hornsea One, said it was ready to step up its plans and fill the gap left by failed nuclear power schemes.

The size of the project takes the burgeoning offshore wind power sector to a new scale, on a par with conventional fossil fuel-fired power stations.

Hornsea One will cover 407 square kilometres, five times the size of the nearby city of Hull. At 1.2GW of capacity it will power 1m homes, making it about twice as powerful as today’s biggest offshore windfarm once it is completed in the second half of this year.

“The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change,” said Matthew Wright, UK managing director of Ørsted, the world’s biggest offshore windfarm builder.

The power station is only the first of four planned in the area, with a green light and subsidies already awarded to a second stage due for completion in the early 2020s, and interest from Japanese utilities underscoring growing investor appetite.

The first two phases will use 7MW turbines, which are taller than London’s Gherkin building.

But the latter stages of the Hornsea development could use even more powerful, 10MW-plus turbines. Bigger turbines will capture more of the energy from the wind and should lower costs by reducing the number of foundations and amount of cabling firms need to put into the water, with developers noting that offshore wind can compete with gas in the U.S. as costs fall.

Henrik Poulsen, Ørsted’s chief executive, said he was in close dialogue with major manufacturers to use the new generation of turbines, some of which are expected to approach the height of the Shard in London, the tallest building in the EU.

The UK has a great wind resource and shallow enough seabed to exploit it, and could even “power most of Europe if it [the UK] went to the extreme with offshore”, he said.

Offshore windfarms could help ministers fill the low carbon power gap created by Hitachi and Toshiba scrapping nuclear plants, the executive suggested. “If nuclear should play less of a role than expected, I believe offshore wind can step up,” he said.

New nuclear projects in Europe had been “dramatically delayed and over budget”, he added, in comparison to “the strong track record for delivering offshore [wind]”.

The UK and Germany installed 85% of new offshore wind power capacity in the EU last year, according to industry data, with wind leading power across several markets. The average power rating of the turbines is getting bigger too, up 15% in 2018.

The turbines for Hornsea One are built and shipped from Siemens Gamesa’s factory in Hull, part of a web of UK-based suppliers that has sprung up around the growing sector, such as Prysmian UK's land cables supporting grid connections.

Around half of the project’s transition pieces, the yellow part of the structure that connects the foundation to the tower, are made in Teeside. Many of the towers themselves are made by a firm in Campbeltown in the Scottish highlands. Altogether, about half of the components for the project are made in the UK.

Ørsted is not yet ready to bid for a share of a £60m pot of further offshore windfarm subsidies, to be auctioned by the government this summer, but expects the price to reach even more competitive levels than those seen in 2017.

Like other international energy companies, Ørsted has put in place contingency planning in event of a no-deal Brexit – but the hope is that will not come to pass. “We want a Brexit deal that will facilitate an orderly transition out of the union,” said Poulsen.

Pennsylvania Electric Rate Increases hit Peco, PPL, and Pike County, driven by natural gas costs and wholesale power markets; default rate changes, price to compare shifts, and time-of-use plans affect residential bills.

Key Points

Electric default rates are rising across Pennsylvania as natural gas costs climb, affecting Peco, PPL, and Pike customers.

✅ PPL, Peco, and Pike raising default rates Dec. 1

✅ Natural gas costs driving wholesale power prices

✅ Consider standard offer, TOU rates, and efficiency

Energy costs for electric customers are going up by as much as 50% across Pennsylvania next week, the latest manifestation of US electricity price increases impacting gasoline, heating oil, propane, and natural gas.

Eight Pennsylvania electric utilities are set to increase their energy prices on Dec. 1, reflecting the higher cost to produce electricity. Peco Energy, which serves Philadelphia and its suburbs, will boost its energy charge by 6.4% on Dec. 1, from 6.6 cents per kilowatt hour to about 7 cents per kWh. Energy charges account for about half of a residential bill.

PPL Electric Utilities, the Allentown company that serves a large swath of Pennsylvania including parts of Bucks, Montgomery, and Chester Counties, will impose a 26% increase on residential energy costs on Dec. 1, from about 7.5 cents per kWh to 9.5 cents per kWh. That’s an increase of $40 a month for an electric heating customer who uses 2,000 kWh a month.

Pike County Light & Power, which serves about 4,800 customers in Northeast Pennsylvania, will increase energy charges by 50%, according to the Pennsylvania Public Utility Commission.

“All electric distribution companies face the same market forces as PPL Electric Utilities,” PPL said in a statement. Each Pennsylvania utility follows a different PUC-regulated plan for procuring energy from power generators, and those forces can include rising nuclear power costs in some regions, which explains why some customers are absorbing the hit sooner rather than later, it said.

There are ways customers can mitigate the impact. Utilities offer a host of programs and grants to support low-income customers, and some states are exploring income-based fixed charges to address affordability, and they encourage anyone struggling to pay their bills to call the utility for help. Customers can also control their costs by conserving energy. It may be time to put on a sweater and weatherize the house.

Peco recently introduced time-of-use rates — as seen when Ontario ended fixed pricing — that include steep discounts for customers who can shift electric usage to late night hours — that’s you, electric vehicle owners.

There’s also a clever opportunity available for many Pennsylvania customers called the “standard offer” that might save you some real money, but you need to act before the new charges take effect on Dec. 1 to lock in the best rates.

Why are the price hikes happening?
But first, how did we get here?

Energy charges are rising for a simple reason: Fuel prices for power generators are increasing, and that’s driven mostly by natural gas. It’s pushing up electricity prices in wholesale power markets and has lifted typical residential bills in recent years.

“It’s all market forces right now,” said Nils Hagen-Frederiksen, PUC spokesperson. Energy charges are strictly a pass-through cost for utilities. Utilities aren’t allowed to mark them up.

The increase in utility energy charges does not affect customers who buy their energy from competitive power suppliers in deregulated electricity markets. About 27% of Pennsylvania’s 5.9 million electric customers who shop for electricity from third-party suppliers either pay fixed rates, whose price remains stable, or are on a variable-rate plan tied to market prices. The variable-rate electric bills have probably already increased to reflect the higher cost of generating power.

Most New Jersey electric customers are shielded for now from rising energy costs. New Jersey sets annual energy prices for customers who don’t shop for power. Those rates go into effect on June 1 and stay in place for 12 months. The current energy market fluctuations will be reflected in new rates that take effect next summer, said Lauren Ugorji, a spokesperson for Public Service Electric & Gas Co., New Jersey’s largest utility.

For each utility, its own plan
Pennsylvania has a different system for setting utility energy charges, which are also known as the “default rate,” because that’s the price a customer gets by default if they don’t shop for power. The default rate is also the same thing as the “price to compare,” a term the PUC has adopted so consumers can make an apples-to-apples comparison between a utility’s energy charge and the price offered by a competitive supplier.

Each of the state’s 11 PUC-regulated electric utilities prepares its own “default service plan,” that governs the method by which they procure power on wholesale markets. Electric distribution companies like Peco are required to buy the lowest priced power. They typically buy power in blind auctions conducted by independent agents, so that there’s no favoritism for affiliated power generators

Some utilities adjust charges quarterly, and others do it semi-annually. “This means that each [utility’s] resulting price to compare will vary as the market changes, some taking longer to reflect price changes, both up and down,” PPL said in a statement. PPL conducted its semi-annual auction in October, when energy prices were rising sharply.

Most utilities buy power from suppliers under contracts of varying durations, both long-term and short-term. The contracts are staggered so market price fluctuations are smoothed out. One utility, Pike County Power & Light, buys all its power on the spot market, which explains why its energy charge will surge by 50% on Dec. 1. Pike County’s energy charge will also be quicker to decline when wholesale prices subside, as they are expected to next year.

Peco adjusts its energy charge quarterly, but it conducts power auctions semi-annually. It buys about 40% of its power in one-year contracts, and 60% in two-year contracts, and does not buy any power on spot markets, said Richard G. Webster Jr., Peco’s vice president of regulatory policy and strategy.

“At any given time, we’re replacing about a third of our supplied portfolio,” he said.

The utility’s energy charge affects only part of the monthly bill. For a Peco residential electric customer who uses 700 kWh per month, the Dec. 1 energy charge increase will boost monthly bills by $2.94 per month, or 2.9%. For an electric heating customer who uses about 2,000 kWh per month, the change will boost bills $8.40 a month, or about 3.5%, said Greg Smore, a Peco spokesperson.
