It was little wonder that Anne Lauvergeon, daughter of a historian and niece of an archaeologist, felt drawn to antiquity as a girl. Until her uncle took her on her first dig one summer.

"I discovered it was a lot of dirt, dirty hands, and crawling around on all fours," Lauvergeon, now 48, said in explaining how her interest had shifted from the past to the future.

She now runs the French nuclear energy company, Areva.

Her long path from dirty hands to the corporate suite took some unexpected turns, leaving her one of the most powerful women in French business. An autonomous streak showed up early.

"I worked in the summer when I was 15 or 16," she said, a rarity among French young people. "I wanted to be independent."

In recent years, nuclear energy risked becoming part of the past, as countries around the world, like the United States, Germany and Japan, refrained from expanding the stock of nuclear power plants they had or, if they had none, like Italy and Poland, refused to plunge into the nuclear age. But the business of nuclear energy has come alive again, and it is people like Lauvergeon who are changing it.

With the volatile cost of carbon fuels, like oil and natural gas, and the need to reduce the level of greenhouse emissions that cause global warming, the promoters of nuclear energy have gone into action. Companies like Westinghouse, General Electric and Areva, which design and build nuclear power plants, are fishing for contracts and landing them in Asia, including China, where nuclear energy is expected to play a large role. Now they are setting their sights on developed countries in the West, like Britain, Germany, the Scandinavian countries and the United States.

"It's not expensive, and the costs are totally predictable," Lauvergeon said in her office in a meticulously restored Art Deco building in the center of Paris. "The cost of uranium is only 5 percent of your costs."

Moreover, she said, nuclear energy created no foreign dependence for fuel and produced no greenhouse gases.

Nuclear power is becoming a case study in globalization, as more countries are induced to include it in their energy plans and to pay other countries for the technology they need.

"A nuclear renaissance is now gearing up everywhere in the world," said John Ritch 3rd, a former U.S. diplomat who is director general of the World Nuclear Association, an industry association. "It is occurring parallel to an enormous expansion in energy consumption."

Of course, not everyone likes the idea of more nuclear energy.

"Currently there is no safe way to deal with radioactive waste," said Nathan Argent, who follows the industry for Greenpeace, one of many anti-nuclear groups. Such groups argue, moreover, that the spread of nuclear technology leads to the proliferation of atomic weapons.

Some governments heed their anti-nuclear constituencies. Germany, once a leader in nuclear energy, is committed to dropping nuclear energy by 2020; Sweden is similarly committed to phasing out its nuclear plants by 2010.

But Lauvergeon is talking about the benefits of nuclear energy as a clean and, she argues, safe alternative to carbon fuels. She highlights Areva's experience in converting spent fuel into mixed oxide, or MOX, pellets, that can be burned in nuclear reactors.

She can speak with conviction because France, unlike most of the world, never backed away from atomic power. About 80 percent of the electricity used in France is generated by nuclear plants.

The new government of President Nicolas Sarkozy is giving Lauvergeon a helping hand. In addressing the United Nations and on trips to countries in the Mediterranean basin, notably Libya and Morocco, Sarkozy has pushed French nuclear technology.

Lauvergeon is emphatic that Areva is not in the business of proliferation. "Without ambiguity, we don't accept to do business with countries that don't accept, without doubt, international controls," she said.

In the first nine months of 2007 Areva had $11.6 billion in revenue, 6.8 percent more than a year earlier, building power plants but also mining and processing uranium and disposing of spent fuel. Its order book in the first half of the year rose 30 percent to $45 billion. It is building two power plants, using the latest design, known as a European pressurized water reactor, in France and in Finland. She expects to sign contracts for two more in China.

Lauvergeon faces strong competition, primarily from Westinghouse, GE and the Russian reactor builder, Atomstroyexport. Westinghouse is now part of Toshiba, and GE operates in cooperation with Hitachi. But Areva is arguably the leader in building nuclear plants in recent years.

Lauvergeon notes that Areva is taking the competition to the Westinghouse home turf, having established a joint venture with Constellation Energy, a Baltimore utility, to sell its power plants in the United States. It is also cooperating with Électricité de France, the French utility, to penetrate the American market. Her sales pitch? "Eighty percent of value should be American," she said. "We want to reinstate the nuclear industry there, which almost disappeared."

Areva has 6,000 employees in the United States, she said, and is constantly training more.

Lauvergeon grew up in Orleans, in the heartland of France, where her father was a professor of geography, though her interest in the past gradually made way for studies at university in chemistry and physics and to a degree from the École des Mines in Paris, an elite engineering school.

After graduation she worked for several French companies, including Usinor, the steel company that is now part of Arcelor Mittal. In 1995, she became a partner in Paris at Lazard Frères, spending several months at the investment bank's New York office.

Lauvergeon assembled Areva in 2001 from the bickering factions of the state-owned nuclear establishment, the fuel company Cogema and the reactor builder Framatome, creating what can ben considered the only one-stop nuclear shop, selling uranium, reactors, fuel reprocessing and waste storage.

It was around that time that she first visited a nuclear reactor. "It was clean, very modern, and I was impressed by the idea that a tiny amount of uranium produced a huge amount of energy," she said. And this, she added, despite her being at the time, "very écolo," French shorthand for environmentalist. To blunt green criticism, she invigorated Cogema's communications policy.

"We were ready to discuss, and not only with our friends," she said. "It was tested. We won."

"At the time, many said we had no future," she went on. "I said, 'We have a future, and we should invest.' In this new situation, we're very attractive."

Now Areva needs cash to grow, and the French government is considering all options, including selling shares in Areva. Less than 5 percent of the company trades on the Paris exchange, via nonvoting investment certificates. A merger with the French turbine maker Alstom is possible. This likelihood has lifted Areva shares more than 50 percent over the past year. Lauvergeon said she favored "an opening of the capital, with one or two industrial partners."

The centerpiece of Lauvergeon's sales pitch is the European pressurized water reactor, and Areva is building the first of its kind in a dark pine forest in Finland. But the Finnish project is years behind schedule with cost overruns reported to be as high as $1 billion. Lauvergeon said Areva did not publish the provisions it makes for such losses, but she confessed that Areva was unlikely to make money on the project.

"It won't be profitable," she said. "It's an investment, an incredible show window."

U.S. Electricity and natural gas prices explained

Energy Pricing Factors span electricity generation, transmission, and distribution costs, plus natural gas supply-demand, renewables, seasonal peaks, and wholesale pricing effects across residential, commercial, and industrial customers, usage patterns, weather, and grid constraints.

 

Key Points

They are the costs and market forces driving electricity and natural gas prices, from generation to delivery and demand.

✅ Generation, transmission, distribution shape electricity rates

✅ Gas prices hinge on supply, storage, imports/exports

✅ Demand shifts: weather, economy, and fuel alternatives

 

There are a lot of factors that affect energy prices globally. What’s included in the price to heat homes and supply them with electricity may be a lot more than some people may think.

Electricity
Generating electricity is the largest component of its price, according to the U.S. Energy Information Administration (EIA). Generation accounts for 56% of the price of electricity, while distribution and transmission account for 31% and 13% respectively.

Homeowners and businesses pay more for electricity than industrial companies, and U.S. electricity prices have recently surged, highlighting broader inflationary pressures. This is because industrial companies can take electricity at higher voltages, reducing transmission costs for energy companies.

“Industrial consumers use more electricity and can receive it at higher voltages, so supplying electricity to these customers is more efficient and less expensive. The price of electricity to industrial customers is generally close to the wholesale price of electricity,” EIA explains.

NYSEG said based on the average use of 600 kilowatt-hours per month, its customers spent the most money on delivery and transition charges in 2020, 57% or about $42, and residential electricity bills increased 5% in 2022 after inflation, according to national data. They also spent on average 35% (~$26) on supply charges and 8% (~$6) on surcharges.

Electricity prices are usually higher in the summer. Why? Because energy companies use sources of electricity that cost more money. It used to be that renewable sources, like solar and wind, were the most expensive sources of energy but increased technological advances have changed this, according to the International Energy Agency’s 2021 World Energy Outlook.

“In most markets, solar PV or wind now represents the cheapest available source of new electricity generation. Clean energy technology is becoming a major new area for investment and employment – and a dynamic arena for international collaboration and competition,” the report said.

Natural gas
The price of natural gas is driven by supply and demand. If there is more supply, prices are generally lower. If there is not as much supply, prices are generally higher the EIA explains. On the other side of the equation, more demand can also increase the price and less demand can decrease the price.

High natural gas prices mean people turn their home thermostats down a few degrees to save money, so the EIA said reduced demand can encourage companies to produce more natural gas, which would in turn help lower the cost. Lower prices will sometimes cause companies to reduce their production, therefore causing the price to rise.

The three major supply factors that affect prices: the amount of natural gas produced, how much is stored, and the volume of gas imported and exported. The three major demand factors that affect price are: changes in winter/summer weather, economic growth, and the broader energy crisis dynamics, as well as how much other fuels are available and their price, said EIA.

To think the price of natural gas is higher when the economy is thriving may sound counterintuitive but that’s exactly what happens. The EIA said this is because of increases in demand.

California Utility Cuts Power to Massive Areas in Northern, Central California

PG&E Public Safety Power Shutoff curbs wildfire risk amid high winds, triggering California outages across Northern California and Bay Area counties; grid safety measures, outage maps, campus closures, and restoration timelines guide residents and businesses.

 

Key Points

A preemptive outage program by PG&E to reduce wildfire ignition during extreme wind events in California.

✅ Cuts power during red flag, high wind, dry fuel conditions

✅ Targets Northern California, Bay Area counties at highest risk

✅ Restoration follows inspections, weather all-clear, hazard checks

 

California utility Pacific Gas and Electric Co. (PG&E) has cut off power supply to hundreds of thousands of residents in Northern and Central California as a precaution to possible breakout of wildfires, a move examined in reasons for shutdowns by industry observers.

PG&E confirmed that about 513,000 customers in many counties in Northern California, including Napa, Sierra, Sonoma and Yuba, were affected in the first phase of Public Safety Power Shutoff, a preemptive measure it took to prevent wildfires believed likely to be triggered by strong, dry winds.

The utility said the decision to shut off power was, amid ongoing debate over nuclear's status in California, "based on forecasts of dry, hot and windy weather including potential fire risk."

"This weather event will last through midday Thursday, with peak winds forecast from Wednesday morning through Thursday morning and reaching 60 mph (about 96 km per hour) to 70 mph (about 112 km per hour) at higher elevations," it said, while abroad National Grid warnings about short supply have highlighted parallel reliability concerns.

PG&E noted that about 234,000 residents in mostly counties of San Francisco Bay Area such as Alameda, Alpine, Contra Costa, San Mateo and Santa Clara were impacted in the second phase of the power shutoff, as the state considers power plant closure delays with potential grid impacts, that began around noon in Wednesday.

The unprecedented power outages sweeping across Northern California has darkened homes and forced schools and business to close, even as the UK paused an emergency energy plan amid its own supply concerns.

University of California, Berkeley canceled all classes for Wednesday due to expected campus power loss over the next few days.

The university said it has received notice from PG&E, as China's power woes cloud U.S. solar supplies that could aid resilience, that "most of the core campus will be without power" possibly for 48 hours.

A freshman at California State University San Jose told Xinhua that their classes were canceled Wednesday as the campus was running out of power.

"I had to go home because even our dormitory went without electricity," the student added.

However, PG&E noted in an updated statement Wednesday night that only 4,000 customers would be affected in the third phase being considered for Kern County in Central California, compared to an earlier forecast of 43,000 people who would experience power outage.

The PG&E power shutoff was the largest preemptive measure ever taken to prevent wildfires in the state's history, and it comes as clean power grows while fossil declines across California's grid, highlighting broader transition challenges.

The San Francisco-based California utility was held responsible for poor management of its power lines that sparked fatal wildfires in Northern California and killed 86 people last year in what was called Camp Fire, the single-deadliest wildfire in California's history.

Several lawsuits and other requests for compensation from wildfire victims that amounted to billions of U.S. dollars forced the embattled the company to claim bankruptcy protection early this year.

EPA: New pollution limits proposed for US coal, gas power plants reflect "urgency" of climate crisis

EPA Power Plant Emissions Rule proposes strict greenhouse gas limits for coal and gas units, leveraging carbon capture (CCS) under the Clean Air Act to cut CO2 and accelerate decarbonization of the U.S. grid.

 

Key Points

A proposed EPA rule setting CO2 limits for coal and gas plants, using CCS to cut power-sector greenhouse gases.

✅ Applies to existing and new coal and large gas units

✅ Targets near-zero CO2 by 2038 via CCS or retirement

✅ Cites grid, health, and climate benefits; faces legal challenges

 

The Biden administration has proposed new limits on greenhouse gas emissions from coal- and gas-fired power plants, its most ambitious effort yet to roll back planet-warming pollution from the nation’s second-largest contributor to climate change.

A rule announced by the Environmental Protection Agency could force power plants to capture smokestack emissions using a technology that has long been promised but is not used widely in the United States, and arrives amid changes stemming from the NEPA rewrite that affect project reviews.

“This administration is committed to meeting the urgency of the climate crisis and taking the necessary actions required,″ said EPA Administrator Michael Regan.

The plan would not only “improve air quality nationwide, but it will bring substantial health benefits to communities all across the country, especially our front-line communities ... that have unjustly borne the burden of pollution for decades,” Regan said in a speech at the University of Maryland.

President Joe Biden, whose climate agenda includes a clean electricity standard as a key pillar, called the plan “a major step forward in the climate crisis and protecting public health.”

If finalized, the proposed regulation would mark the first time the federal government has restricted carbon dioxide emissions from existing power plants, following a Trump-era replacement of Obama’s power plant overhaul, which generate about 25% of U.S. greenhouse gas pollution, second only to the transportation sector. The rule also would apply to future electric plants and would avoid up to 617 million metric tons of carbon dioxide through 2042, equivalent to annual emissions of 137 million passenger vehicles, the EPA said.

Almost all coal plants — along with large, frequently used gas-fired plants — would have to cut or capture nearly all their carbon dioxide emissions by 2038, the EPA said, a timeline that echoed concerns raised during proposed electricity pricing changes in the prior administration. Plants that cannot meet the new standards would be forced to retire.

The plan is likely to be challenged by industry groups and Republican-leaning states, much like litigation over the Affordable Clean Energy rule unfolded in recent years. They have accused the Democratic administration of overreach on environmental regulations and warn of a pending reliability crisis for the electric grid. The power plant rule is one of at least a half-dozen EPA rules limiting power plant emissions and wastewater treatment rules.

“It’s truly an onslaught” of government regulation “designed to shut down the coal fleet prematurely,″ said Rich Nolan, president and CEO of the National Mining Association.

Regan denied that the power plant rule was aimed at shutting down the coal sector, but acknowledged — even after the end to the 'war on coal' rhetoric — “We will see some coal retirements.”

Experts Question Quebec's Push for EV Dominance

Quebec EV transition plan aims for 2 million electric vehicles by 2030 and bans new gas cars by 2035, stressing charging infrastructure, incentives, emissions cuts, and industry impacts, with debate over feasibility and economic risks.

 

Key Points

A provincial policy targeting 2M EVs by 2030 and a 2035 gas-car sales ban, backed by charging buildout and incentives.

✅ Requires major charging infrastructure and grid upgrades

✅ Balances incentives with economic impacts and industry readiness

✅ Gas stations persist while EV adoption accelerates cautiously

 

Quebec's ambitious push to dominate the electric vehicle (EV) market, echoing Canada's EV goals in its plan, by setting a target of two million EVs on the road by 2030 and planning to ban the sale of new gas-powered vehicles by 2035 has sparked significant debate among industry experts. While the government's objectives aim to reduce greenhouse gas emissions and promote sustainable transportation, some experts question the feasibility and potential economic impacts of such rapid transitions.

Current Landscape of Gas Stations in Quebec

Contrary to Environment Minister Benoit Charette's assertion that gas stations may become scarce within the next decade, industry experts suggest that the number of gas stations in Quebec is unlikely to decline drastically. Carol Montreuil, Vice President of the Canadian Fuels Association, describes the minister's statement as "wishful thinking," emphasizing that the number of gas stations has remained relatively stable over the past decade. Statistics indicate that in 2023, Quebec residents purchased more gasoline than ever before, and EV shortages and wait times further underscore the continued demand for traditional fuel sources.

Challenges in Accelerating EV Adoption

The government's goal of having two million EVs on Quebec roads by 2030 presents several challenges. Currently, there are approximately 200,000 fully electric cars in the province. Achieving a tenfold increase in less than a decade requires substantial investments in charging infrastructure, consumer incentives, and public education to address concerns such as range anxiety and charging accessibility, especially amid electricity shortage warnings across Quebec and other provinces.

Economic Considerations and Industry Concerns

Industry stakeholders express concerns about the economic implications of rapidly phasing out gas-powered vehicles. Montreuil warns that the industry is already struggling and that attempting to transition too quickly could lead to economic challenges, a view echoed by critics who label the 2035 EV mandate delusional. He suggests that the government may be spending excessive public funds on subsidies for technologies that are still expensive and not yet widely adopted.

Public Sentiment and Adoption Rates

Public sentiment towards EVs is mixed, and experiences in Manitoba suggest the road to targets is not smooth. While some consumers, like Montreal resident Alex Rajabi, have made the switch to electric vehicles and are satisfied with their decision, others remain hesitant due to concerns about vehicle cost, charging infrastructure, and the availability of incentives. Rajabi, who transitioned to an EV nine months ago, notes that while he did not take advantage of the incentive program, he is happy with his decision and suggests that adding charging ports at gas stations could facilitate the transition.

The Need for a Balanced Approach

Experts advocate for a balanced approach that considers the pace of technological advancements, consumer readiness, and economic impacts. While the transition to electric vehicles is essential for environmental sustainability, it is crucial to ensure that the infrastructure, market conditions, and public acceptance are adequately addressed, and to recognize that a share of Canada's electricity still comes from fossil fuels, to make the shift both feasible and beneficial for all stakeholders.

In summary, Quebec's ambitious EV targets reflect a strong commitment to environmental sustainability. However, industry experts caution that achieving these goals requires careful planning, substantial investment, and a realistic assessment of the challenges involved as federal EV sales regulations take shape, in transitioning from traditional vehicles to electric mobility.

Philippines Ranks Highest in Coal-Generated Power Dependency

Philippines coal dependency underscores energy transition challenges, climate change risks, and air pollution, as rising electricity demand, fossil fuels, and emissions shape policy shifts toward renewable energy, grid reliability, and sustainable development.

 

Key Points

It is rising reliance on coal for power, driven by demand and cost, with climate, air pollution, and policy risks.

✅ Driven by rising demand, affordability, and grid reliability.

✅ Worsens emissions, air pollution, and public health burdens.

✅ Policy shifts aim at renewable energy, efficiency, and standards.

 

In a striking development, the Philippines has surpassed China and Indonesia to become the nation most dependent on coal-generated power in recent years. This shift highlights significant implications for the country's energy strategy, environmental policies, and its commitment to sustainable development, and comes as global power demand continues to surge worldwide.

Rising Dependency on Coal

The Philippines' increasing reliance on coal-generated power is driven by several factors, including rapid economic growth, rising electricity demand, and regional uncertainties in China's electricity sector that influence fuel markets, and the perceived affordability and reliability of coal as an energy source. Coal has historically been a key component of the Philippines' energy mix, providing a stable supply of electricity to support industrialization and urbanization efforts.

Environmental and Health Impacts

Despite its economic benefits, coal-generated power comes with significant environmental and health costs, especially as soaring electricity and coal use amplifies exposure to pollution. Coal combustion releases greenhouse gases such as carbon dioxide, contributing to global warming and climate change. Additionally, coal-fired power plants emit pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which pose health risks to nearby communities and degrade air quality.

Policy and Regulatory Landscape

The Philippines' energy policies have evolved to address the challenges posed by coal dependency while promoting sustainable alternatives. The government has introduced initiatives to encourage renewable energy development, improve energy efficiency, and, alongside stricter emissions standards on coal-fired power plants, is evaluating nuclear power for inclusion in the energy mix to meet future demand. However, balancing economic growth with environmental protection remains a complex and ongoing challenge.

International and Domestic Pressures

Internationally, there is growing pressure on countries to reduce reliance on fossil fuels and transition towards cleaner energy sources as part of global climate commitments under the Paris Agreement, illustrated by the United Kingdom's plan to end coal power within its grid. The Philippines' status as the most coal-dependent nation underscores the urgency for policymakers to accelerate the shift towards renewable energy and reduce carbon emissions to mitigate climate impacts.

Challenges and Opportunities

Transitioning away from coal-generated power presents both challenges and opportunities for the Philippines. Challenges include overcoming entrenched interests in the coal industry, addressing energy security concerns, and navigating the economic implications of energy transition, particularly as clean energy investment in developing nations has recently declined, adding financial headwinds. However, embracing renewable energy offers opportunities to diversify the energy mix, reduce dependence on imported fuels, create green jobs, and improve energy access in remote areas.

Community and Stakeholder Engagement

Engaging communities and stakeholders is crucial in shaping the Philippines' energy transition strategy. Local residents, environmental advocates, industry leaders, and policymakers play essential roles in fostering dialogue, raising awareness about the benefits of renewable energy, and advocating for policies that promote sustainable development and protect public health.

Future Outlook

The Philippines' path towards reducing coal dependency and advancing renewable energy is critical to achieving long-term sustainability and resilience against climate change impacts. By investing in renewable energy infrastructure, enhancing energy efficiency measures, and fostering innovation in clean technologies, as renewables poised to eclipse coal indicate broader momentum, the country can mitigate environmental risks, improve energy security, and contribute to global efforts to combat climate change.

Conclusion

As the Philippines surpasses China and Indonesia in coal-generated power dependency, the nation faces pivotal decisions regarding its energy future. Balancing economic growth with environmental stewardship requires strategic investments in renewable energy, robust policy frameworks, and proactive engagement with stakeholders to achieve a sustainable and resilient energy system. By prioritizing clean energy solutions, the Philippines can pave the way towards a greener and more sustainable future for generations to come.

Europe Stores Electricity in Natural Gas Pipes

Power-to-gas converts surplus renewable electricity into green hydrogen or synthetic methane via electrolysis and methanation, enabling seasonal energy storage, grid balancing, hydrogen injection into gas pipelines, and decarbonization of heat, transport, and industry.

 

Key Points

Power-to-gas turns excess renewable power into hydrogen or methane for storage, grid support, and clean fuel.

✅ Enables hydrogen injection into existing natural gas networks

✅ Balances grids and provides seasonal energy storage capacity

✅ Supplies low-carbon fuels for industry, heat, and heavy transport

 

Last month Denmark’s biggest energy firm, Ørsted, said wind farms it is proposing for the North Sea will convert some of their excess power into gas. Electricity flowing in from offshore will feed on-shore electrolysis plants that split water to produce clean-burning hydrogen, with oxygen as a by-product. That would supply a new set of customers who need energy, but not as electricity. And it would take some strain off of Europe’s power grid as it grapples with an ever-increasing share of hard-to-handle EU wind and solar output on the grid.

Turning clean electricity into energetic gases such as hydrogen or methane is an old idea that is making a comeback as renewable power generation surges and crowds out gas in Europe. That is because gases can be stockpiled within the natural gas distribution system to cover times of weak winds and sunlight. They can also provide concentrated energy to replace fossil fuels for vehicles and industries. Although many U.S. energy experts argue that this “power-to-gas” vision may be prohibitively expensive, some of Europe’s biggest industrial firms are buying in to the idea.

European power equipment manufacturers, anticipating a wave of renewable hydrogen projects such as Ørsted’s, vowed in January that, as countries push for hydrogen-ready power plants across Europe, all of their gas-fired turbines will be certified by next year to run on up to 20 percent hydrogen, which burns faster than methane-rich natural gas. The natural gas distributors, meanwhile, have said they will use hydrogen to help them fully de-carbonize Europe’s gas supplies by 2050.

Converting power to gas is picking up steam in Europe because the region has more consistent and aggressive climate policies and evolving electricity pricing frameworks that support integration. Most U.S. states have goals to clean up some fraction of their electricity supply; coal- and gas-fired plants contribute a little more than a quarter of U.S. greenhouse gas emissions. In contrast, European countries are counting on carbon reductions of 80 percent or more by midcentury—reductions that will require an economywide switch to low-carbon energy.

Cleaning up energy by stripping the carbon out of fossil fuels is costly. So is building massive new grid infrastructure, including transmission lines and huge batteries, amid persistent grid expansion woes in parts of Europe. Power-to-gas may be the cheapest way forward, complementing Germany’s net-zero roadmap to cut electricity costs by a third. “In order to reach the targets for climate protection, we need even more renewable energy. Green hydrogen is perceived as one of the most promising ways to make the energy transition happen,” says Armin Schnettler, head of energy and electronics research at Munich-based electric equipment giant Siemens.

Europe already has more than 45 demonstration projects to improve power-to-gas technologies and their integration with power grids and gas networks. The principal focus has been to make the electrolyzers that convert electricity to hydrogen more efficient, longer-lasting and cheaper to produce.

The projects are also scaling up the various technologies. Early installations converted a few hundred kilowatts of electricity, but manufacturers such as Siemens are now building equipment that can convert 10 megawatts, which would yield enough hydrogen each year to heat around 3,000 homes or fuel 100 buses, according to financial consultancy Ernst & Young.

The improvements have been most dramatic for proton-exchange membrane electrolyzers, which are akin to the fuel cells used in hydrogen vehicles (but optimized to produce hydrogen rather than consume it). The price of proton-exchange electrolyzers has dropped by roughly 40 percent during the past decade, according to a study published in February in Nature Energy. They are also five times more compact than older alkaline electrolysis plants, enabling onsite hydrogen production near gas consumers, and they can vary their power consumption within seconds to operate on fluctuating wind and solar generation.

Many European pilot projects are demonstrating “methanation” equipment that converts hydrogen to methane, too, which can be used as a drop-in replacement for natural gas. Europe’s electrolyzer plants, however, are showing that methanation is not as critical to the power-to-gas vision as advocates long believed. Many electrolyzers are injecting their hydrogen directly into natural gas pipelines—something that U.S. gas firms forbid—and they are doing so without impacting either the gas infrastructure or natural gas consumers.

Europe’s first large-scale hydrogen injection began in eastern Germany in 2013 at a two-megawatt electrolyzer installed by Essen-based power firm E.ON. Germany has since ratcheted up the amount of hydrogen it allows in natural gas lines from an initial 2 percent by volume to 10 percent, in a market where renewables now outpace coal and nuclear in Germany, and other European states have followed suit with their own hydrogen allowances. Christopher Hebling, head of hydrogen technologies at the Freiburg-based Fraunhofer Institute for Solar Energy Systems, predicts that such limits will rise to the 20-percent level anticipated by Europe’s turbine manufacturers.

Moving renewable hydrogen and methane via natural gas pipelines promises to cut the cost of switching to renewable energy. For example, gas networks have storage caverns whose reserves could be tapped to run gas-fired electric generation power plants during periods of low wind and solar output. Hebling notes that Germany’s gas network can store 240 terawatt-hours of energy—roughly 25 times more energy than global power grids can presently store by pumping water uphill to refill hydropower reservoirs. Repurposing gas infrastructure to help the power system could save European consumers 138 billion euros ($156 billion) by 2050, according to Dutch energy consultancy Navigant (formerly Ecofys).

For all the pilot plants and promise, renewable hydrogen presently supplies a tiny fraction of Europe’s gas. And, globally, around 4 percent of hydrogen is supplied via electrolysis, with the bulk refined from fossil fuels, according to the International Renewable Energy Agency.

Power-to-gas is catching up, however. According to the February Nature Energy study, renewable hydrogen already pays for itself in some niche applications, and further electrolyzer improvements will progressively extend its market. “If costs continue to decline as they have done in recent years, power-to-gas will become competitive at large scale within the next decade,” says study co-author Gunther Glenk, an economist at the Technical University of Munich.

Glenk says power-to-gas could scale up faster if governments guaranteed premium prices for renewable hydrogen and methane, as they did to mainstream solar and wind power.

Tim Calver, an energy storage researcher turned consultant and Ernst & Young’s executive director in London, agrees that European governments need to step up their support for power-to-gas projects and markets. Calver calls the scale of funding to date, “not proportionate to the challenge that we face on long-term decarbonization and the potential role of hydrogen.”
