Indonesia to build 10 coal-fired power plants

U.S. Energy Transition Delays stem from grid bottlenecks, permitting red tape, solar tariff uncertainty, supply-chain shocks, and scarce affordable EVs, risking deeper fossil fuel lock-in despite climate targets for renewables, transmission expansion, and decarbonization.

Key Points

Delays driven by grid limits, permitting, and supply shocks that slow renewables, transmission, EVs, and decarbonization.

✅ Grid interconnection and transmission backlogs stall renewables

✅ Tariff probes and supply chains disrupt utility-scale solar

✅ Permitting, policy gaps, and EV costs sustain fossil fuel use

Big solar projects are facing major delays. Plans to adapt the grid to clean energy are confronting mountains of red tape. Affordable electric vehicles are in short supply.

The United States is struggling to squeeze opportunity out of an energy crisis that should have been a catalyst for cleaner, domestically produced power. After decades of putting the climate on the back burner, the country is finding itself unprepared to seize the moment and at risk of emerging from the crisis even more reliant on fossil fuels.

10 steps you can take to lower your carbon footprint
The problem is not entirely unique to the United States. Across the globe, climate leaders are warning that energy shortages including coal and nuclear disruptions prompted by Russia’s unprovoked invasion of Ukraine and high gas prices driven by inflation threaten to make the energy transition an afterthought — potentially thwarting efforts to keep global temperature rise under 1.5 degrees Celsius.

“The energy crisis exacerbated by the war in Ukraine has seen a perilous doubling down on fossil fuels by the major economies,” U.N. Secretary General António Guterres said at a conference in Vienna on Tuesday, according to prepared remarks. He warned governments and investors that a failure to immediately and more aggressively embrace clean energy could be disastrous for the planet.

U.S. climate envoy John F. Kerry suggested that nations are falling prey to a flawed logic that fossil fuels will help them weather this period of instability, undermining U.S. national security and climate goals, which has seen gas prices climb to a record-high national average of $5 per gallon. “You have this new revisionism suggesting that we have to be pumping oil like crazy, and we have to be moving into long-term [fossil fuel] infrastructure building,” he said at the Time100 Summit in New York this month. “We have to push back.”

In the United States — the world’s second-largest emitter of greenhouse gases after China — the hurdles go beyond the supply-chain crisis and sanctions linked to the war in Ukraine. The country’s lofty goals for all carbon pollution to be gone from the electricity sector by 2035 and for half the cars sold to be electric by 2030 are jeopardized by years of neglect of the electrical grid, regulatory hurdles that have set projects back years, and failures by Congress and policymakers to plan ahead.
The challenges are further compounded by plans to build costly new infrastructure for drilling and exporting natural gas that will make it even harder to transition away from the fossil fuel.

“We are running into structural challenges preventing consumers and businesses from going cleaner, even at this time of high oil and gas prices,” said Paul Bledsoe, a climate adviser in the Clinton administration who now works on strategy at the Progressive Policy Institute, a center-left think tank. “It is a little alarming that even now, Congress is barely talking about clean energy.”

Consumers are eager for more wind and solar. Companies looking to go carbon-neutral are facing growing waitlists for access to green energy, and a Pew Research Center poll in late January found that two-thirds of Americans want the United States to prioritize alternative energy over fossil fuel production.

But lawmakers have balked for more than a decade at making most of the fundamental economic and policy changes such as a clean electricity standard that experts widely agree are crucial to an orderly and accelerated energy transition. The United States does not have a tax on carbon, nor a national cap-and-trade program that would reorient markets toward lowering emissions. The unraveling in Congress of President Biden’s $1.75 trillion Build Back Better plan has added to the head winds that green-energy developers face, even as climate law results remain mixed.

“There is literally nothing pushing this forward in the U.S. beyond the tax code and some state laws,” said Heather Zichal, a former White House climate adviser who is now the chief executive of the American Clean Power Association.

The effects of the U.S. government’s halting approach are being felt by solar-panel installers, who saw the number of projects in the most recent quarter fall to the lowest level since the pandemic began. There was 24 percent less solar installed in the first quarter of 2022 than in the same quarter of 2021.

The holdup largely stems from a Commerce Department investigation into alleged tariff-dodging by Chinese manufacturers. Faced with the potential for steep retroactive penalties, hundreds of industrial-scale solar projects were frozen in early April. Weak federal policies to encourage investment in solar manufacturing left American companies ill-equipped to fill the void.

“We shut down multiple projects and had to lay off dozens of people,” said George Hershman, chief executive of SOLV Energy, which specializes in large solar installations. SOLV, like dozens of other solar companies, is now scrambling to reassemble those projects after the administration announced a pause of the tariffs.

Meanwhile, adding clean electricity to the aging power grid has become an increasingly complicated undertaking, given the failure to plan for adequate transmission lines and long delays connecting viable wind and solar projects to the electricity network.

Coal-to-Clean Energy Hubs leverage Bipartisan Infrastructure Law and Inflation Reduction Act funding to repurpose mine lands with microgrids, advanced nuclear, carbon capture, and rare earth processing, boosting energy security, jobs, and grid modernization.

Key Points

They are federal projects converting coal communities and mine lands into clean energy hubs, repurposing infrastructure.

✅ DOE demos on mine lands: microgrids, nuclear, carbon capture.

✅ Funding from BIL, CHIPS and IRA targets energy communities.

✅ Rare earths from coal waste bolster EV supply chains.

The Biden administration is channeling hundreds of millions of dollars in clean energy funding from recent legislation into its efforts to turn coal communities into clean energy hubs, the White House said.

The administration gave an update on its push across agencies to kick-start projects nationwide with funding Congress approved during Biden’s first two years in office. The effort includes $450 million from the Bipartisan Infrastructure Law that the Department of Energy will allocate to an array of new clean energy demonstration projects on former mine lands.

“These projects could focus on a range of technologies from microgrids to advanced nuclear to power plans with carbon capture,” Energy Secretary Jennifer Granholm said on a call with reporters Monday. “They’ll prove out the potential to reactivate or repurpose existing infrastructure like transmission lines and substations across an aging U.S. power grid, and these projects could spur new economic development in these communities.”

Among the projects the White House highlighted, it said $16 million from the infrastructure law will go to the University of North Dakota and West Virginia University to create design studies for the first-ever full-scale refinery facility in the U.S. that could extract and separate rare earth elements and minerals from coal mine waste streams. The materials are critical for electric vehicle-battery components that are currently heavily sourced from outside the U.S.

“Those efforts will pave the way toward building a first of its kind facility that produces essential materials for solar panels, wind turbines, EVs and more while cleaning up polluted land and water and creating good-paying jobs for local workers,” Granholm said.

Biden created an interagency working group focused on revitalizing coal-power communities through federal investments when he took office. In 2021, the group selected 25 priority areas ranging from West Virginia to Wyoming to focus on development, as high natural gas prices strengthened the case for clean electricity. There are nearly 18,000 identified mine sites across 1.5 million acres in the United States, according to the White House.

The massive effort fits into a broader Biden administration push to both fight climate change and support communities that have lost economic activity during a transition away from fossil fuel sources such as coal. While Biden’s most ambitious clean energy plans fell flat in Congress in the face of opposition from Republicans and some Democrats after the previous administration’s power plant overhaul, three major laws still unlocked funding for his administration to deploy.

Many of the initiatives are made possible through the Bipartisan Infrastructure Law, Chips and Science Act and the Inflation Reduction Act, even without a clean electricity standard on the books. The task force aims to make sure communities most affected by the changing energy landscape are taking maximum advantage of the federal benefits.

“Those new and expanded operations are coming to energy communities and creating good paying jobs,” Biden’s senior advisor for clean energy innovation and implementation John Podesta said on the call. “These laws can provide substantial federal support to energy communities like capping abandoned oil and gas wells, extracting critical minerals, building battery factories and launching demonstration projects in carbon capture or green hydrogen.”

The administration touted the potential benefits of the Inflation Reduction Act, a bill passed by Democrats to spur clean energy investments last year, even as early assessments show mixed results to date. At the time, U.S. consumers were dealing with decades-high inflation fueled in part by an energy crisis and high gas prices that drove debate — a point Republicans emphasized as the plan moved through Congress.

Deputy Treasury Secretary Wally Adeyemo said the Inflation Reduction Act aims to both “lower the deficit, as well as promote our energy security, lowering energy costs for consumers and combatting climate change.”

“As the Treasury works to implement the law, we’re focused on ensuring that all Americans benefit from the growth of the clean energy economy, particularly those who live in communities that have been dependent on the energy sector for job for a long time,” Adeyemo told reporters. “Economic growth and productivity are higher when all communities are able to reach their full potential.”

California Managed Decline of Fossil Fuels aligns oil phaseout with carbon neutrality, leveraging ZEV adoption, solar and wind growth, severance taxes, drilling setbacks, fracking oversight, CARB rules, and CalGEM regulation to deliver a just transition.

Key Points

California's strategy to phase out oil and gas while meeting carbon-neutral goals through policy, regulation, and equity.

✅ Severance taxes fund clean energy and workforce transition.

✅ Setbacks restrict drilling near schools, homes, and hospitals.

✅ CARB and CalGEM tighten fracking oversight and ZEV targets.

California’s energy past is on a collision course with its future. Think of major oil-producing U.S. states, and Texas, Alaska or North Dakota probably come to mind. Although its position relative to other states has been falling for 20 years, California remains the seventh-largest oil-producing state, with 162 million barrels of crude coming up in 2018, translating to tax revenue and jobs.

At the same time, California leads the nation in solar rooftops and electric vehicles on the road by a wide margin and ranking fifth in installed wind capacity. Clean energy is the state’s future, and the state is increasingly exporting its energy policies across the West, influencing regional markets. By law, California must have 100 percent carbon-free electricity by 2045, and an executive order signed by former Governor Jerry Brown calls for economywide carbon-neutrality by the same year.

So how can the state reconcile its divergent energy path? How should clean-energy-minded lawmakers wind down California’s oil and gas sector in a way that aligns with the state’s long-term climate targets while providing a just transition for the industry’s workforce?

Any efforts to reduce fossil fuel supply must run parallel to aggressive demand-reduction measures such as California’s push to have 5 million zero-emission vehicles on the road by 2030, said Ethan Elkind, director of Berkeley Law's climate program, especially amid debates over keeping the lights on without fossil fuels in the near term. After all, if oil demand in California remains strong, crude from outside the state will simply fill the void.

“If we don’t stop using it, then that supply is going to get here, even if it’s not produced in-state,” Elkind said in an interview.

Lawmakers have a number of options for policies that would draw down and eventually phase out fossil fuel production in California, according to a new report from the Center for Law, Energy and the Environment at the UC Berkeley School of Law, co-authored by Elkind and Ted Lamm.

They could impose a higher price on California's oil production through a "severance" tax or carbon-based fee, with the revenue directed to measures that wean the state from fossil fuels. (California, alone among major oil-producing states, does not have an oil severance tax.)

Lawmakers could establish a minimum drilling setback from schools, playgrounds, homes and other sensitive sites. They could push the state's oil and gas regulator, the California Geologic Energy Management Division, to prioritize environmental and climate concerns.

A major factor holding lawmakers back is, of course, politics, including debates over blackouts and climate policy that shape public perception. Given the state’s clean-energy ambitions, it might surprise non-Californians that the oil and gas industry is one of the Golden State’s most powerful special interest groups.

Overcoming a "third-rail issue" in California politics
The Western States Petroleum Association, the sector’s trade group in California's capital of Sacramento, spent $8.8 million lobbying state policymakers in 2019, more than any other interest group. Over the last five years, the group, which cultivates both Democratic and Republican lawmakers, has spent $43.3 million on lobbying, nearly double the total of the second-largest lobbying spender.

Despite former Governor Brown’s reputation as a climate champion, critics say he was unwilling to forcefully take on the oil and gas industry. However, things may take a different turn under Brown's successor, Governor Gavin Newsom.

In May 2019, when Newsom released California's midyear budget revision (PDF), the governor's office noted the need for "careful study and planning to decrease demand and supply of fossil fuels, while managing the decline in a way that is economically responsible and sustainable.”

Related reliability concerns surfaced as blackouts revealed lapses in power supply across the state.

Writing for the advocacy organization Oil Change International, David Turnbull observed, “This may mark the first time that a sitting governor in California has recognized the need to embark upon a managed decline of fossil fuel supply in the state.”

“It is significant because typically this is one of those third-rail issues, kind of a hot potato that governors don’t even want to touch at all — including Jerry Brown, to a large extent, who really focused much more on the demand side of fuel consumption in the state,” said Berkeley Law’s Elkind.

California's revised budget included $1.5 million for a Transition to a Carbon-Neutral Economy report, which is being prepared by University of California researchers for the California Environmental Protection Agency. In an email, a CalEPA spokesperson said the report is due by the end of this year.

Winding down oil and gas production
Since the release of the revised budget last May, Newsom has taken initial steps to increase oversight of the oil and gas industry. In July 2019, he fired the state’s top oil and gas regulator for issuing too many permits to hydraulically fracture, or frack, wells.

Later in the year, he appointed new leadership to oversee oil and gas regulation in the state, and he signed a package of bills that placed constraints on fossil fuel production. The next month, Newsom halted the approval of new fracking operations until pending permits could be reviewed by a panel of scientists at Lawrence Livermore National Laboratory. The California Geologic Energy Management Division (CalGEM) did not resume issuing fracking permit approvals until April of this year.

Not all steps have been in the same direction. This month Newsom dropped a proposal to add dozens of analysts, engineers and geologists at CalGEM, citing COVID-related economic pressure. The move would have increased regulatory oversight on fossil fuel producers and was opposed by the state's oil industry.

Ultimately, more durable measures to wind down fossil fuel supply and demand will require new legislation, even as regulators weigh whether the state needs more power plants to maintain reliability.

A 2019 bill by Assemblymember Al Muratsuchi (D-Torrance), AB 345, would have codified the minimum 2,500-foot setback for new oil and gas wells. However, before the final vote in the Assembly, the bill’s buffer requirement was dropped and replaced with a requirement for CalGEM “to consider a setback distance of 2,500 feet.” The bill passed the Assembly in January over "no" votes from several moderate Democrats; it now awaits action in the Senate.

A bill previously introduced by Assemblymember Phil Ting (D-San Francisco), AB 1745, didn’t even make it that far. Ting’s bill would have required that all new passenger cars registered in the state after January 1, 2040, be zero-emission vehicles (ZEV). The bill died in committee without a vote in April 2018.

But the backing of the California Air Resources Board (CARB), one of the world's most powerful air-quality regulators, could change the political conversation. In March, CARB chair Mary Nichols said she now supports consideration of California establishing a 100 percent zero-emission vehicle sales target by 2030, as policymakers also consider a revamp of electricity rates to clean the grid.

“In the past, I’ve been skeptical about whether that would do more harm than good in terms of the backlash by dealers and others against something that sounded so un-California like,” Nichols said during an online event. “But as time has gone on, I’ve become more convinced that we need to send the longer-term signal about where we’re headed.”

Another complicating factor for California’s political leaders is the lack of a willing federal partner — at least in the short term — in winding down oil and gas production, amid warnings about a looming electricity shortage that could pressure the grid.

Under the Trump administration, the Bureau of Land Management, which oversees 15 million acres of federal land in California, has pushed to open more than 1 million acres of public and private land across eight counties in Central California to fracking. In January 2020, California filed a federal lawsuit to block the move.

ERCOT Texas Power Grid Crisis disrupts millions amid a winter storm, with rolling blackouts, power outages, and energy demand; Elon Musk criticizes ERCOT as Tesla owners use Camp Mode while wind turbines face icing

Key Points

A Texas blackout during a winter storm, exposing ERCOT failures, rolling blackouts, and urgent grid resilience measures.

✅ Millions without power amid record cold and energy demand

✅ Elon Musk criticizes ERCOT over grid reliability failures

✅ Tesla Camp Mode aids warmth during extended outages

Tesla CEO Elon Musk on Wednesday slammed the Texas agency responsible for a statewide blackout amid a U.S. grid with frequent outages that has left millions of people to fend for themselves in a freezing cold winter storm.

Musk tweeted that Texas’ power grid manager, the Electricity Reliability Council of Texas (ERCOT), is not earning the “R” in the acronym, highlighting broader grid vulnerabilities that critics have noted.

Musk moved to Texas from California in December and is building a new Tesla factory in Austin. His critique of the state’s electrical grid operator came after multiple Tesla owners in the state said they had slept in their vehicles to keep warm amid the lingering power outage.

In 2019, Tesla released a vehicle with a “Camp Mode,” which enables owners to use the vehicle’s features – like lights and climate control – without significantly depleting the battery.

“We had the power go out for 6 hours last night. Our house does not have gas, and we ran out of firewood... what are we going to do,” one Reddit user wrote on “r/TeslaMotors.”

“So my wife my dog and my newborn daughter slept in the garage in our Model3 all nice and cozy. If I didn't have this car, it would have been a very rough night.”

More than two dozen people have died in the extreme weather this week, some while struggling to find warmth inside their homes. In the Houston area, one family succumbed to carbon monoxide from car exhaust in their garage. Another perished as they used a fireplace to keep warm.

Utilities from Minnesota to Texas and Mississippi have implemented rolling blackouts to ease the burden on power grids straining to meet extreme demand for heat and electricity, as longer, more frequent outages hit systems nationwide.

More than 3 million customers remained without power in Texas, Louisiana and Mississippi, more than 200,000 more in four Appalachian states, and nearly that many in the Pacific Northwest, according to poweroutage.us, which tracks utility outage reports, and advocates warn that millions could face summer shut-offs without protections.

ERCOT said early Wednesday that electricity had been restored to 600,000 homes and businesses by Tuesday night, though nearly 3 million homes and businesses remained without power, as California turns to batteries to help balance demand. Officials did not know when power would be restored.

ERCOT President Bill Magness said he hoped many customers would see at least partial service restored soon but could not say definitively when that would be.

Magness has defended ERCOT’s decision, saying it prevented an “even more catastrophic than the terrible events we've seen this week."

Utility crews raced Wednesday to restore power to nearly 3.4 million customers around the U.S. who were still without electricity in the aftermath of a deadly winter storm, even as officials urge residents to prepare for summer blackouts that could tax systems further, and another blast of ice and snow threatened to sow more chaos.

The latest storm front was expected to bring more hardship to states that are unaccustomed to such frigid weather — parts of Texas, Arkansas and the Lower Mississippi Valley — before moving into the Northeast on Thursday.

"There's really no letup to some of the misery people are feeling across that area," said Bob Oravec, lead forecaster with the National Weather Service, referring to Texas.

Sweden, known for its brutally cold climate, has offered some advice to Texans unaccustomed to such freezing temperatures, as Canadian grids are increasingly exposed to harsh weather that strains reliability. Stefan Skarp of the Swedish power company told Bloomberg on Tuesday: “The problem with sub-zero temperatures and humid air is that ice will form on the wind turbines.”

“When ice freezes on to the wings, the aerodynamic changes for the worse so that wings catch less and less wind until they don't catch any wind at all,” he said.

Covid-19 Energy Transition and Machine Learning reshape climate change policy, electricity planning, and grid operations, from demand forecasting and decarbonization strategies in Europe to scalable electrification modeling and renewable integration across Africa.

Key Points

How the pandemic reshapes energy policy and how ML improves planning, demand forecasts, and grid reliability in Africa.

✅ Pandemic-driven demand shifts strain grid operations and markets

✅ Policy momentum risks rollback; favor future-oriented decarbonization

✅ ML boosts demand prediction, electrification, and grid reliability in Africa

The impact of Covid-19 on the energy system was discussed in an online climate change workshop that also considered how machine learning can help electricity planning in Africa.

This year’s International Conference on Learning Representations event included a workshop held by the Climate Change AI group of academics and artificial intelligence industry representatives, which considered how machine learning can help tackle climate change and highlighted advances by European electricity prediction specialists working in this field.

Bjarne Steffen, senior researcher at the energy politics group at ETH Zürich, shared his insights at the workshop on how Covid-19 and the accompanying economic crisis are affecting recently introduced ‘green’ policies. “The crisis hit at a time when energy policies were experiencing increasing momentum towards climate action, especially in Europe, and in proposals to invest in smarter electricity infrastructure for long-term resilience,” said Steffen, who added the coronavirus pandemic has cast into doubt the implementation of such progressive policies.

The academic said there was a risk of overreacting to the public health crisis, as far as progress towards climate change goals was concerned.

Lobbying

“Many interest groups from carbon-intensive industries are pushing to remove the emissions trading system and other green policies,” said Steffen. “In cases where those policies are having a serious impact on carbon-emitting industries, governments should offer temporary waivers during this temporary crisis, instead of overhauling the regulatory structure.”

However, the ETH Zürich researcher said any temptation to impose environmental conditions to bail-outs for carbon-intensive industries should be resisted. “While it is tempting to push a green agenda in the relief packages, tying short-term environmental conditions to bail-outs is impractical, given the uncertainty in how long this crisis will last,” he said. “It is better to include provisions that will give more control over future decisions to decarbonize industries, such as the government taking equity shares in companies.”

Steffen shared with pv magazine readers an article published in Joule which can be accessed here, and which articulates his arguments about how Covid-19 could affect the energy transition.

Covid-19 in the U.K.

The electricity system in the U.K. is also being affected by Covid-19, even as the U.S. electric grid grapples with climate risks, according to Jack Kelly, founder of London-based, not-for-profit, greenhouse gas emission reduction research laboratory Open Climate Fix.

“The crisis has reduced overall electricity use in the U.K.,” said Kelly. “Residential use has increased but this has not offset reductions in commercial and industrial loads.”

Steve Wallace, a power system manager at British electricity system operator National Grid ESO recently told U.K. broadcaster the BBC electricity demand has fallen 15-20% across the U.K. The National Grid ESO blog has stated the fall-off makes managing grid functions such as voltage regulation more challenging.

Open Climate Fix’s Kelly noted even events such as a nationally-coordinated round of applause for key workers was followed by a dramatic surge in demand, stating: “On April 16, the National Grid saw a nearly 1 GW spike in electricity demand over 10 minutes after everyone finished clapping for healthcare workers and went about the rest of their evenings.”

Climate Change AI workshop panelists also discussed the impact machine learning could have on improving electricity planning in Africa. The Electricity Growth and Use in Developing Economies (e-Guide) initiative funded by fossil fuel philanthropic organization the Rockefeller Foundation aims to use data to improve the planning and operation of electricity systems in developing countries.

E-Guide members Nathan Williams, an assistant professor at the Rochester Institute of Technology (RIT) in New York state, and Simone Fobi, a PhD student at Columbia University in NYC, spoke about their work at the Climate Change AI workshop, which closed on Thursday. Williams emphasized the importance of demand prediction, saying: “Uncertainty around current and future electricity consumption leads to inefficient planning. The weak link for energy planning tools is the poor quality of demand data.”

Fobi said: “We are trying to use machine learning to make use of lower-quality data and still be able to make strong predictions.”

The market maturity of individual solar home systems and PV mini-grids in Africa mean more complex electrification plan modeling is required, similar to integrating AI data centers into Canada's grids at scale.

Modeling

“When we are doing [electricity] access planning, we are trying to figure out where the demand will be and how much demand will exist so we can propose the right technology,” added Fobi. “This makes demand estimation crucial to efficient planning.”

Unlike many traditional modeling approaches, machine learning is scalable and transferable. Rochester’s Williams has been using data from nations such as Kenya, which are more advanced in their electrification efforts, to train machine learning models to make predictions to guide electrification efforts in countries which are not as far down the track.

Williams also discussed work being undertaken by e-Guide members at the Colorado School of Mines, which uses nighttime satellite imagery and machine learning to assess the reliability of grid infrastructure in India, where new algorithms to prevent ransomware-induced blackouts are also advancing.

Rural power

Another e-Guide project, led by Jay Taneja at the University of Massachusetts, Amherst – and co-funded by the Energy and Economic Growth program on development spending based at Berkeley – uses satellite imagery to identify productive uses of electricity in rural areas by detecting pollution signals from diesel irrigation pumps.

Though good quality data is often not readily available for Africa, Williams added, it does exist.

“We have spent years developing trusting relationships with utilities,” said the RIT academic. “Once our partners realize the value proposition we can offer, they are enthusiastic about sharing their data … We can’t do machine learning without high-quality data and this requires that organizations can effectively collect, organize, store and work with data. Data can transform the electricity sector, as shown by Canadian projects to use AI for energy savings, but capacity building is crucial.”

Nuclear decarbonization leverages low-carbon electricity, process heat, and hydrogen from advanced reactors and SMRs to electrify industry, buildings, and transport, supporting net-zero strategies and grid flexibility alongside renewables with dispatchable baseload capacity.

Key Points

Nuclear decarbonization uses reactors to supply low-carbon power, heat, and hydrogen, cutting emissions across industry.

✅ Advanced reactors and SMRs enable high-temperature process heat

✅ Nuclear-powered electrolysis and HTSE produce low-carbon hydrogen

✅ District heating from reactors reduces pollution and coal use

By Dr Henri Paillere, Head of the Planning and Economics Studies Section of the IAEA

Decarbonising the power sector will not be sufficient to achieving net-zero emissions, with assessments indicating nuclear may be essential across sectors. We also need to decarbonise the non-power sectors - transport, buildings and industry - which represent 60% of emissions from the energy sector today. The way to do that is: electrification with low-carbon electricity as much as possible; using low-carbon heat sources; and using low-carbon fuels, including hydrogen, produced from clean electricity.
The International Energy Agency (IEA) says that: 'Almost half of the emissions reductions needed to reach net zero by 2050 will need to come from technologies that have not reached the market today.' So there is a need to innovate and push the research, development and deployment of technologies. That includes nuclear beyond electricity.

Today, most of the scenario projections see nuclear's role ONLY in the power sector, despite ongoing debates over whether nuclear power is in decline globally, but increased electrification will require more low-carbon electricity, so potentially more nuclear. Nuclear energy is also a source of low-carbon heat, and could also be used to produce low-carbon fuels such as hydrogen. This is a virtually untapped potential.

There is an opportunity for the nuclear energy sector - from advanced reactors, next-gen nuclear small modular reactors, and non-power applications - but it requires a level playing field, not only in terms of financing today's technologies, but also in terms of promoting innovation and supporting research up to market deployment. And of course technology readiness and economics will be key to their success.

On process heat and district heating, I would draw attention to the fact there have been decades of experience in nuclear district heating. Not well spread, but experience nonetheless, in Russia, Hungary and Switzerland. Last year, we had two new projects. One floating nuclear power plant in Russia (Akademik Lomonosov), which provides not only electricity but district heating to the region of Pevek where it is connected. And in China, the Haiyang nuclear power plant (AP1000 technology) has started delivering commercial district heating. In China, there is an additional motivation to reducing emissions, namely to cut air pollution because in northern China a lot of the heating in winter is provided by coal-fired boilers. By going nuclear with district heating they are therefore cutting down on this pollution and helping with reducing carbon emissions as well. And Poland is looking at high-temperature reactors to replace its fleet of coal-fired boilers and so that's a technology that could also be a game-changer on the industry side.

There have also been decades of research into the production of hydrogen using nuclear energy, but no real deployment. Now, from a climate point of view, there is a clear drive to find substitute fuels for the hydrocarbon fuels that we use today, and multiple new nuclear stations are seen by industry leaders as necessary to meet net-zero targets. In the near term, we will be able to produce hydrogen with electrolysis using low-carbon electricity, from renewables and nuclear. But the cheapest source of low-carbon power is from the long-term operation of existing nuclear power plants which, combined with their high capacity factors, can give the cheapest low-carbon hydrogen of all.

In the mid to long term, there is research on-going with processes that are more efficient than low-temperature electrolysis, which is high temperature steam electrolysis or thermal splitting of water. These may offer higher efficiencies and effectiveness but they also require advanced reactors that are still under development. Demonstration projects are being considered in several countries and we at the IAEA are developing a publication that looks into the business opportunities for nuclear production of hydrogen from existing reactors. In some countries, there is a need to boost the economics of the existing fleet, especially in the electricity systems where you have low or even negative market prices for electricity. So, we are looking at other products that have higher values to improve the competitiveness of existing nuclear power plants.

The future means not only looking at electricity, but also at industry and transport, and so integrated energy systems. Electricity will be the main workhorse of our global decarbonisation effort, but through heat and hydrogen. How you model this is the object of a lot of research work being done by different institutes and we at the IAEA are developing some modelling capabilities with the objective of optimising low-carbon emissions and overall costs.

This is just a picture of what the future might look like: a low-carbon power system with nuclear lightwater reactors (large reactors, small modular reactors and fast reactors) drawing on the green industrial revolution reactor waves in planning; solar, wind, anything that produces low-carbon electricity that can be used to electrify industry, transport, and the heating and cooling of buildings. But we know there is a need for high-temperature process steam that electricity cannot bring but which can be delivered directly by high-temperature reactors. And there are a number of ways of producing low-carbon hydrogen. The beauty of hydrogen is that it can be stored and it could possibly be injected into gas networks that could be run in the future on 100% hydrogen, and this could be converted back into electricity.

So, for decarbonising power, there are many options - nuclear, hydro, variable renewables, with renewables poised to surpass coal in global generation, and fossil with carbon capture and storage - and it's up to countries and industries to invest in the ones they prefer. We find that nuclear can actually reduce the overall cost of systems due to its dispatchability and the fact that variable renewables have a cost because of their intermittency. There is a need for appropriate market designs and the role of governments to encourage investments in nuclear.

Decarbonising other sectors will be as important as decarbonising electricity, from ways to produce low-carbon heat and low-carbon hydrogen. It's not so obvious who will be the clear winners, but I would say that since nuclear can produce all three low-carbon vectors - electricity, heat and hydrogen - it should have the advantage.
We at the IAEA will be organising a webinar next month with the IEA looking at long-term nuclear projections in a net-zero world, building on IAEA analysis on COVID-19 and low-carbon electricity insights. That will be our contribution from the point of view of nuclear to the IEA's special report on roadmaps to net zero that it will publish in May.
