A major California utility trying to shore up its sources of electricity isn't giving up its fight to build a major transmission line despite Arizona regulators' attempt to short-circuit the project.

The 230-mile, high-voltage line would make it easier for Southern California Edison, a utility serving most of Southern California, to import electricity available from natural gas-fueled generating plants in Arizona.

However, the Arizona Corporation Commission rejected the project on May 30, saying its environmental features and potential economic benefits were one-sided in favor of California at Arizona's expense.

Since then, Edison has unsuccessfully asked the commission to reconsider its denial and then filed a lawsuit that contends, among other things, that the commission's rejection of the project illegally interferes with interstate commerce.

Edison and the Arizona commission recently agreed to put the lawsuit on hold until next March while the utility considers unspecified alternatives, though one Arizona commissioner told The Associated Press in an interview that he wasn't impressed by what he'd heard so far.

Looming in the background is the possibility that Edison could try to circumvent the Arizona regulators' denial by seeking federal approval of the project as part of a critical energy corridor.

The continued wrangling over the proposed power line comes as California utilities strain the meet their customers' demand for electricity, a situation aggravated last week by high temperatures.

California's electricity grid manager declared a minor power emergency as the state's operating energy reserves dipped below 7 percent, a step that triggered conservation efforts by state agencies and a call for residents to conserve power use during hot afternoon hours.

Known as Devers-Palo Verde No. 2, the line would cross the desert of Southwestern Arizona and southeastern California, largely paralleling an existing line and linking a power switching yard 40 miles from Phoenix with a substation 10 miles from Palm Springs.

Edison spokesman Paul Klein said the legal hold put on the lawsuit gives Edison time to "pursue other options" that he declined to discuss.

However, Corporation Commission member Bill Mundell said Edison officials have suggested adding an interconnection point somewhere along the line so that it would be more helpful to Arizona's use of the Western power grid.

"That was the only one of substance that they mentioned," Mundell said. "I'll certainly listen to their proposal with an open mind but there needs to be additional benefits."

Mundell, who during the May 30 meeting said he didn't want Arizona to be "an energy farm for California," contends California hasn't done enough to build new plants to meet the energy needs of itself and the region.

Mundell and other Arizona commissioners contend building the line would mean lower electricity prices for California utility customers but higher ones for Arizonans.

An Aug. 14 letter signed by all five Arizona commissioners to members of the state's congressional delegation says the U.S. Department of Energy's expected designation of a high-priority electricity corridor in Arizona, California and Nevada "certainly" will lead to Edison's asking federal officials to authorize the line.

"Our worst nightmare has come true," Mundell said, referring to the Arizona commission's earlier concerns about how the Energy Policy Act of 2005 could be implemented.

Klein, the Edison spokesman, declined to discuss whether the company intends to seek federal authorization for the line.

"At this point we're just looking at all of our options," he said.

Global oil demand to decline in 2020 as Coronavirus weighs heavily on markets

COVID-19 Impact on Global Oil Demand 2020 signals an IEA forecast of declining consumption as travel restrictions curb transport fuels, disrupt energy markets, and shift OPEC and non-OPEC supply dynamics amid economic slowdown.

 

Key Points

IEA sees first demand drop since 2009 as COVID-19 curbs travel, weakening transport fuels and unsettling energy markets.

✅ IEA base case: 2020 demand at 99.9 mb/d, down 90 kb/d from 2019.

✅ Travel restrictions hit transport fuels; China drives the decline.

✅ Scenarios: low -730 kb/d; high +480 kb/d in 2020.

 

Global oil demand is expected to decline in 2020 as the impact of the new coronavirus (COVID-19) spreads around the world, constricting travel and broader economic activity, according to the International Energy Agency’s latest oil market forecast.

The situation remains fluid, creating an extraordinary degree of uncertainty over what the full global impact of the virus will be. In the IEA’s central base case, even as global CO2 emissions flatlined in 2019 according to the IEA, demand this year drops for the first time since 2009 because of the deep contraction in oil consumption in China, and major disruptions to global travel and trade.

“The coronavirus crisis is affecting a wide range of energy markets – including coal-fired electricity generation, gas and renewables – but its impact on oil markets is particularly severe because it is stopping people and goods from moving around, dealing a heavy blow to demand for transport fuels,” said Dr Fatih Birol, the IEA’s Executive Director. “This is especially true in China, the largest energy consumer in the world, which accounted for more than 80% of global oil demand growth last year. While the repercussions of the virus are spreading to other parts of the world, what happens in China will have major implications for global energy and oil markets.”

The IEA now sees global oil demand at 99.9 million barrels a day in 2020, down around 90,000 barrels a day from 2019. This is a sharp downgrade from the IEA’s forecast in February, which predicted global oil demand would grow by 825,000 barrels a day in 2020.

The short-term outlook for the oil market will ultimately depend on how quickly governments move to contain the coronavirus outbreak, how successful their efforts are, and what lingering impact the global health crisis has on economic activity.

To account for the extreme uncertainty facing energy markets, the IEA has developed two other scenarios for how global oil demand could evolve this year. In a more pessimistic low case, global measures fail to contain the virus, and global demand falls by 730,000 barrels a day in 2020. In a more optimistic high case, the virus is contained quickly around the world, and global demand grows by 480,000 barrels a day.

“We are following the situation extremely closely and will provide regular updates to our forecasts as the picture becomes clearer,” Dr Birol said. “The impact of the coronavirus on oil markets may be temporary. But the longer-term challenges facing the world’s suppliers are not going to go away, especially those heavily dependent on oil and gas revenues. As the IEA has repeatedly said, these producer countries need more dynamic and diversified economies in order to navigate the multiple uncertainties that we see today.”

The IEA also published its medium-term outlook examining the key issues in global demand, supply, refining and trade to 2025, as well as the trajectory of the global energy transition now shaping markets. Following a contraction in 2020 and an expected sharp rebound in 2021, yearly growth in global oil demand is set to slow as consumption of transport fuels grows more slowly and as national net-zero pathways, with Canada needing more electricity to reach net-zero influencing power demand, according to the report. Between 2019 and 2025, global oil demand is expected to grow at an average annual rate of just below 1 million barrels a day. Over the period as whole, demand rises by a total of 5.7 million barrels a day, with China and India accounting for about half of the growth.

At the same time, the world’s oil production capacity is expected to rise by 5.9 million barrels a day, with more than three-quarters of it coming from non-OPEC producers, the report forecasts. But production growth in the United States and other non-OPEC countries is set to lose momentum after 2022, amid shifts in Wall Street's energy strategy linked to policy signals, allowing OPEC producers from the Middle East to turn the taps back up to help keep the global oil market in balance.

The medium-term market report, Oil 2020, also considers the impact of clean energy transitions on oil market trends. Demand growth for gasoline and diesel between 2019 and 2025 is forecast to weaken as countries around the world implement policies to improve efficiency and cut carbon dioxide emissions – and as solar power becomes the cheapest electricity in many markets and electric vehicles increase in popularity. The impact of energy transitions on oil supply remains unclear, with many companies prioritising short-cycle projects for the coming years.

“The coronavirus crisis is adding to the uncertainties the global oil industry faces as it contemplates new investments and business strategies,” Dr Birol said. “The pressures on companies are changing, with European oil majors turning electric to diversify. They need to show that they can deliver not just the energy that economies rely on, but also the emissions reductions that the world needs to help tackle our climate challenge.”

Is Hydrogen The Future For Power Companies?

Hydrogen Energy Transition accelerates green hydrogen, electrolyzers, renewables, and fuel cells, as the EU and US scale decarbonization, NextEra tests hydrogen-to-power, and DOE funds pilots to replace natural gas and cut CO2.

 

Key Points

A shift to deploy green hydrogen tech to decarbonize power, industry, and transport across EU and US energy systems.

✅ EU targets 40 GW electrolyzers plus 40 GW imports by 2030

✅ DOE funds pilots; NextEra trials hydrogen-to-power at Okeechobee

✅ Aims to replace natural gas, enable fuel cells, cut CO2

 

Last month, the European Union set out a comprehensive hydrogen strategy as part of its goal to achieve carbon neutrality for all its industries by 2050. The EU has an ambitious target to build out at least 40 gigawatts of electrolyzers within its borders by 2030 and also support the development of another 40 gigawatts of green hydrogen in nearby countries that can export to the region by the same date. The announcement came as little surprise, given that Europe is regarded as being far ahead of the United States in the shift to renewable energy, even as it looks to catch up on fuel cells with Asian leaders today.

But the hydrogen bug has finally arrived stateside: The U.S. Department of Energy has unveiled the H2@Scale initiative whereby a handful of companies including Cummins Inc. (NYSE: CMI), Caterpillar Inc.(NYSE: CAT), 3M Company (NYSE: MMM), Plug Power Inc.(NASDAQ: PLUG) and EV startup Nikola Corp.(NASDAQ: NKLA), even as the industry faces threats to the EV boom that investors are watching, will receive $64 million in government funding for hydrogen research projects.

Hot on the heels of the DoE initiative: American electric utility and renewable energy giant, NextEra Energy Inc.(NYSE: NEE), has unveiled an equally ambitious plan to start replacing its natural gas-powered plants with hydrogen.

During its latest earnings call, NextEra’s CFO Rebecca Kujawa said the company is “…particularly excited about the long-term potential of hydrogen” and discussed plans to start a pilot hydrogen project at one of its generating stations at Okeechobee Clean Energy Center owned by its subsidiary, Florida Power & Light (FPL). NextEra reported Q2 revenue of $4.2B (-15.5% Y/Y), which fell short of Wall Street’s consensus by $1.12B while GAAP EPS of $2.59 (+1.1% Y/Y) beat estimates by $0.09. The company attributed the big revenue slump to the effects of Covid-19.

Renewable energy and hydrogen stocks have lately become hot property as EV adoption hits an inflection point worldwide, with NEE up 16% in the year-to-date; PLUG +144%, Bloom Energy Corp. (NYSE: BE) +62.8% while Ballard Power Systems (NASDAQ: BLDP) has gained 98.2% over the timeframe.

NextEra’s usual modus operandi involves conducting small experiments with new technologies to establish their cost-effectiveness, a pragmatic approach informed by how electricity changed in 2021 across the grid, before going big if the trials are successful.

CFO Kujawa told analysts:
“Based on our ongoing analysis of the long-term potential of low-cost renewables, we remain confident as ever that wind, solar, and battery storage will be hugely disruptive to the country’s existing generation fleet, while reducing cost for customers and helping to achieve future CO2 emissions reductions. However, to achieve an emissions-free future, we believe that other technologies will be necessary, and we are particularly excited about the long-term potential of hydrogen.”

NextEra plans to test the electricity-to-hydrogen-to-electricity model at its natural gas-powered Okeechobee Clean Energy Center that came online in 2019. Okeechobee is already regarded as one of the cleanest thermal energy facilities anywhere on the globe. However, replacing natural gas with zero emissions hydrogen would be a significant step in helping the company achieve its goal to become 100% emissions-free by 2050.

Kujawa said the company plans to continue evaluating other potential hydrogen opportunities to accelerate the decarbonization of transportation fuel, amid the debate over the future of vehicles between electricity and hydrogen, and industrial feedstock and also support future demand for low-cost renewables.

Another critical milestone: NextEra finished the quarter with a renewables backlog of approximately 14,400 megawatts, its largest in its 20-year development history. To put that backlog into context, NextEra revealed that it is larger than the operating wind and solar portfolios of all but two companies in the world.

Hydrogen Bubble?
That said, not everybody is buying the hydrogen hype.

Barron’s Bill Apton says Wall Street has discovered hydrogen this year and that hydrogen stocks are a bubble, even as hybrid vehicles gain momentum in the U.S. market according to recent reports. Apton says the huge runup by Plug Power, Ballard Energy, and Bloom Energy has left them trading at more than 50x future cash flow, making it hard for them to grow into their steep valuations. He notes that smaller hydrogen companies are up against big players and deep-pocketed manufacturers, including government-backed rivals in China and the likes of Cummins.

According to Apton, it could take a decade or more before environmentally-friendly hydrogen can become competitive with natural gas on a cost-basis, while new ideas like flow battery cars also vie for attention, making hydrogen stocks better long-term picks than the cult stocks they have become.

A new nuclear reactor in the U.S. starts up. It's the first in nearly seven years

Vogtle Unit 3 Initial Criticality marks the startup of a new U.S. nuclear reactor, initiating fission to produce heat, steam, and electricity, supporting clean energy goals, grid reliability, and carbon-free baseload power.

 

Key Points

Vogtle Unit 3 Initial Criticality is the first fission startup, launching power generation at a new U.S. reactor.

✅ First new U.S. reactor to reach criticality since 2016

✅ Generates carbon-free baseload power for the grid

✅ Faced cost overruns and delays during construction

 

For the first time in almost seven years, a new nuclear reactor has started up in the United States.

On Monday, Georgia Power announced that the Vogtle nuclear reactor Unit 3 has started a nuclear reaction inside the reactor as part of the first new reactors in decades now taking shape at the plant.

Technically, this is called “initial criticality.” It’s when the nuclear fission process starts splitting atoms and generating heat, Georgia Power said in a written announcement.

The heat generated in the nuclear reactor causes water to boil. The resulting steam spins a turbine that’s connected to a generator that creates electricity.

Vogtle’s Unit 3 reactor will be fully in service in May or June, Georgia Power said.

The last time a nuclear reactor reached the same milestone was almost seven years ago in May 2016 when the Tennessee Valley Authority started splitting atoms at the Watts Bar Unit 2 reactor in Tennessee, Scott Burnell, a spokesperson for the Nuclear Regulatory Commission, told CNBC.

“This is a truly exciting time as we prepare to bring online a new nuclear unit that will serve our state with clean and emission-free energy for the next 60 to 80 years,” Chris Womack, CEO of Georgia Power, said in a written statement. 

Including the newly turned-on Vogtle Unit 3 reactor, there are currently 93 nuclear reactors operating in the United States and, collectively, they generate 20% of the electricity in the country, although a South Carolina plant leak recently showed how outages can sideline a unit for weeks.

Nuclear reactors, which help combat global warming and support net-zero emissions goals, generate about half of the clean, carbon-free electricity generated in the U.S.

Most of the nuclear power reactors in the United States were constructed between 1970 and 1990, but construction slowed significantly after the accident at Three Mile Island near Middletown, Pennsylvania, on March 28, 1979, even as interest in next-gen nuclear power has grown in recent years. From 1979 through 1988, 67 nuclear reactor construction projects were canceled, according to the U.S. Energy Information Administration.

However, because nuclear energy is generated without releasing carbon dioxide emissions, which cause global warming, the increased sense of urgency in responding to climate change has given nuclear energy a chance at a renaissance as atomic energy heats up again globally.

The cost associated with building nuclear reactors is a major barrier to a potential resurgence in nuclear energy, however, even as nuclear generation costs have fallen to a ten-year low. And the new builds at Vogtle have become an epitome of that charge: The construction of the two Vogtle reactors has been plagued by cost overruns and delays.

Germany turns its back on nuclear for good despite Europe's energy crisis

Germany nuclear phase-out underscores a high-stakes energy transition, trading reactors for renewables, LNG imports, and grid resilience to secure supply, cut emissions, and navigate climate policy, public opinion shifts, and post-Ukraine supply shocks.

 

Key Points

Germany's nuclear phase-out retires reactors, shifting to renewables, LNG, and grid upgrades for low-carbon power.

✅ Last three reactors: Neckarwestheim, Isar 2, and Emsland closed

✅ Supply secured via LNG imports, renewables, and grid flexibility

✅ Policy accelerated post-Fukushima; debate renewed after Ukraine war

 

The German government is phasing out nuclear power despite the energy crisis. The country is pulling the plug on its last three reactors, betting it will succeed in its green transition without nuclear power.

On the banks of the Neckar River, not far from Stuttgart in south Germany, the white steam escaping from the nuclear power plant in Baden-Württemberg will soon be a memory.

The same applies further east for the Bavarian Isar 2 complex and the Emsland complex, at the other end of the country, not far from the Dutch border.

While many Western countries depend on nuclear power, Europe's largest economy is turning the page, even if a possible resurgence of nuclear energy is debated until the end.

Germany is implementing the decision to phase out nuclear power taken in 2002 and accelerated by Angela Merkel in 2011, after the Fukushima disaster.

Fukushima showed that "even in a high-tech country like Japan, the risks associated with nuclear energy cannot be controlled 100 per cent", the former chancellor justified at the time.

The announcement convinced public opinion in a country where the powerful anti-nuclear movement was initially fuelled by fears of a Cold War conflict, and then by accidents such as Chernobyl.

The invasion of Ukraine on 24 February 2022 brought everything into question. Deprived of Russian gas, the flow of which was essentially interrupted by Moscow, Germany found itself exposed to the worst possible scenarios, from the risk of its factories being shut down to the risk of being without heating in the middle of winter.

With just a few months to go before the initial deadline for closing the last three reactors on 31 December, the tide of public opinion began to turn, and talk of a U-turn on the nuclear phaseout grew louder. 

"With high energy prices and the burning issue of climate change, there were of course calls to extend the plants," says Jochen Winkler, mayor of Neckarwestheim, where the plant of the same name is in its final days.

Olaf Scholz's government, which the Green Party - the most hostile to nuclear power - is part of, finally decided to extend the operation of the reactors to secure the supply until 15 April.

"There might have been a new discussion if the winter had been more difficult if there had been power cuts and gas shortages nationwide. But we have had a winter without too many problems," thanks to the massive import of liquefied natural gas, notes Mr Winkler.

Offshore wind is set to become a $1 trillion business

Offshore wind power accelerates low-carbon electrification, leveraging floating turbines, high capacity factors, HVDC transmission, and hydrogen production to decarbonize grids, cut CO2, and deliver competitive, reliable renewable energy near demand centers.

 

Key Points

Offshore wind power uses offshore turbines to deliver low-carbon electricity with high capacity factors and falling costs.

✅ Sea-based wind farms with 40-50% capacity factors

✅ Floating turbines unlock deep-water, far-shore resources

✅ Enables hydrogen production and strengthens grid reliability

 

The need for affordable low-carbon technologies is greater than ever

Global energy-related CO2 emissions reached a historic high in 2018, driven by an increase in coal use in the power sector. Despite impressive gains for renewables, fossil fuels still account for nearly two-thirds of electricity generation, the same share as 20 years ago. There are signs of a shift, with increasing pledges to decarbonise economies and tackle air pollution, and with World Bank support helping developing countries scale wind, but action needs to accelerate to meet sustainable energy goals. As electrification of the global energy system continues, the need for clean and affordable low-carbon technologies to produce this electricity is more pressing than ever. This World Energy Outlook special report offers a deep dive on a technology that today has a total capacity of 23 GW (80% of it in Europe) and accounts for only 0.3% of global electricity generation, but has the potential to become a mainstay of the world's power supply. The report provides the most comprehensive analysis to date of the global outlook for offshore wind, its contributions to electricity systems and its role in clean energy transitions.

 

The offshore wind market has been gaining momentum

The global offshore wind market grew nearly 30% per year between 2010 and 2018, benefitting from rapid technology improvements. Over the next five years, about 150 new offshore wind projects are scheduled to be completed around the world, pointing to an increasing role for offshore wind in power supplies. Europe has fostered the technology's development, led by the UK offshore wind sector alongside Germany and Denmark. The United Kingdom and Germany currently have the largest offshore wind capacity in operation, while Denmark produced 15% of its electricity from offshore wind in 2018. China added more capacity than any other country in 2018.

 

The untapped potential of offshore wind is vast

The best offshore wind sites could supply more than the total amount of electricity consumed worldwide today. And that would involve tapping only the sites close to shores. The IEA initiated a new geospatial analysis for this report to assess offshore wind technical potential country by country. The analysis was based on the latest global weather data on wind speed and quality while factoring in the newest turbine designs. Offshore wind's technical potential is 36 000 TWh per year for installations in water less than 60 metres deep and within 60 km from shore. Global electricity demand is currently 23 000 TWh. Moving further from shore and into deeper waters, floating turbines could unlock enough potential to meet the world's total electricity demand 11 times over in 2040. Our new geospatial analysis indicates that offshore wind alone could meet several times electricity demand in a number of countries, including in Europe, the United States and Japan. The industry is adapting various floating foundation technologies that have already been proven in the oil and gas sector. The first projects are under development and look to prove the feasibility and cost-effectiveness of floating offshore wind technologies.

 

Offshore wind's attributes are very promising for power systems

New offshore wind projects have capacity factors of 40-50%, as larger turbines and other technology improvements are helping to make the most of available wind resources. At these levels, offshore wind matches the capacity factors of gas- and coal-fired power plants in some regions – though offshore wind is not available at all times. Its capacity factors exceed those of onshore wind and are about double those of solar PV. Offshore wind output varies according to the strength of the wind, but its hourly variability is lower than that of solar PV. Offshore wind typically fluctuates within a narrower band, up to 20% from hour to hour, than solar PV, which varies up to 40%.

Offshore wind's high capacity factors and lower variability make its system value comparable to baseload technologies, placing it in a category of its own – a variable baseload technology. Offshore wind can generate electricity during all hours of the day and tends to produce more electricity in winter months in Europe, the United States and China, as well as during the monsoon season in India. These characteristics mean that offshore wind's system value is generally higher than that of its onshore counterpart and more stable over time than that of solar PV. Offshore wind also contributes to electricity security, with its high availability and seasonality patterns it is able to make a stronger contribution to system needs than other variable renewables. In doing so, offshore wind contributes to reducing CO2 and air pollutant emissions while also lowering the need for investment in dispatchable power plants. Offshore wind also has the advantage of avoiding many land use and social acceptance issues that other variable renewables are facing.

 

Offshore wind is on track to be a competitive source of electricity

Offshore wind is set to be competitive with fossil fuels within the next decade, as well as with other renewables including solar PV. The cost of offshore wind is declining and is set to fall further. Financing costs account for 35% to 50% of overall generation cost, and supportive policy frameworks are now enabling projects to secure low cost financing in Europe, with zero-subsidy tenders being awarded. Technology costs are also falling. The levelised cost of electricity produced by offshore wind is projected to decline by nearly 60% by 2040. Combined with its relatively high value to the system, this will make offshore wind one of the most competitive sources of electricity. In Europe, recent auctions indicate that offshore wind will soon beat new natural gas-fired capacity on cost and be on a par with solar PV and onshore wind. In China, offshore wind is set to become competitive with new coal-fired capacity around 2030 and be on par with solar PV and onshore wind. In the United States, recent project proposals indicate that offshore wind will soon be an affordable option, even as the 1 GW timeline continues to evolve, with potential to serve demand centres along the country's east coast.

Innovation is delivering deep cost reductions in offshore wind, and transmission costs will become increasingly important. The average upfront cost to build a 1 gigawatt offshore wind project, including transmission, was over $4 billion in 2018, but the cost is set to drop by more than 40% over the next decade. This overall decline is driven by a 60% reduction in the costs of turbines, foundations and their installation. Transmission accounts for around one-quarter of total offshore wind costs today, but its share in total costs is set to increase to about one-half as new projects move further from shore. Innovation in transmission, for example through work to expand the limits of direct current technologies, will be essential to support new projects without raising their overall costs.

 

Offshore wind is set to become a $1 trillion business

Offshore wind power capacity is set to increase by at least 15-fold worldwide by 2040, becoming a $1 trillion business. Under current investment plans and policies, the global offshore wind market is set to expand by 13% per year, reflecting its growth despite Covid-19 in recent years, passing 20 GW of additions per year by 2030. This will require capital spending of $840 billion over the next two decades, almost matching that for natural gas-fired or coal-fired capacity. Achieving global climate and sustainability goals would require faster growth: capacity additions would need to approach 40 GW per year in the 2030s, pushing cumulative investment to over $1.2 trillion. 

The promising outlook for offshore wind is underpinned by policy support in an increasing number of regions. Several European North Seas countries – including the United Kingdom, Germany, the Netherlands and Denmark – have policy targets supporting offshore wind. Although a relative newcomer to the technology, China is quickly building up its offshore wind industry, aiming to develop a project pipeline of 10 GW by 2020. In the United States, state-level targets and federal incentives are set to kick-start the U.S. offshore wind surge in the coming years. Additionally, policy targets are in place and projects under development in Korea, Japan, Chinese Taipei and Viet Nam.

 The synergies between offshore wind and offshore oil and gas activities provide new market opportunities. Since offshore energy operations share technologies and elements of their supply chains, oil and gas companies started investing in offshore wind projects many years ago. We estimate that about 40% of the full lifetime costs of an offshore wind project, including construction and maintenance, have significant synergies with the offshore oil and gas sector. That translates into a market opportunity of $400 billion or more in Europe and China over the next two decades. The construction of foundations and subsea structures offers potential crossover business, as do practices related to the maintenance and inspection of platforms. In addition to these opportunities, offshore oil and gas platforms require electricity that is often supplied by gas turbines or diesel engines, but that could be provided by nearby wind farms, thereby reducing CO2 emissions, air pollutants and costs.

 

Offshore wind can accelerate clean energy transitions

Offshore wind can help drive energy transitions by decarbonising electricity and by producing low-carbon fuels. Over the next two decades, its expansion could avoid between 5 billion and 7 billion tonnes of CO2 emissions from the power sector globally, while also reducing air pollution and enhancing energy security by reducing reliance on imported fuels. The European Union is poised to continue leading the wind energy at sea in Europe industry in support of its climate goals: its offshore wind capacity is set to increase by at least fourfold by 2030. This growth puts offshore wind on track to become the European Union's largest source of electricity in the 2040s. Beyond electricity, offshore wind's high capacity factors and falling costs makes it a good match to produce low-carbon hydrogen, a versatile product that could help decarbonise the buildings sector and some of the hardest to abate activities in industry and transport. For example, a 1 gigawatt offshore wind project could produce enough low-carbon hydrogen to heat about 250 000 homes. Rising demand for low-carbon hydrogen could also dramatically increase the market potential for offshore wind. Europe is looking to develop offshore "hubs" for producing electricity and clean hydrogen from offshore wind.

 

It's not all smooth sailing

Offshore wind faces several challenges that could slow its growth in established and emerging markets, but policy makers and regulators can clear the path ahead. Developing efficient supply chains is crucial for the offshore wind industry to deliver low-cost projects. Doing so is likely to call for multibillion-dollar investments in ever-larger support vessels and construction equipment. Such investment is especially difficult in the face of uncertainty. Governments can facilitate investment of this kind by establishing a long-term vision for offshore wind and by drawing on U.K. policy lessons to define the measures to be taken to help make that vision a reality. Long-term clarity would also enable effective system integration of offshore wind, including system planning to ensure reliability during periods of low wind availability.

The success of offshore wind depends on developing onshore grid infrastructure. Whether the responsibility for developing offshore transmission lies with project developers or transmission system operators, regulations should encourage efficient planning and design practices that support the long-term vision for offshore wind. Those regulations should recognise that the development of onshore grid infrastructure is essential to the efficient integration of power production from offshore wind. Without appropriate grid reinforcements and expansion, there is a risk of large amounts of offshore wind power going unused, and opportunities for further expansion could be stifled. Development could also be slowed by marine planning practices, regulations for awarding development rights and public acceptance issues.

The future of offshore wind looks bright but hinges on the right policies

The outlook for offshore wind is very positive as efforts to decarbonise and reduce local pollution accelerate. While offshore wind provides just 0.3% of global electricity supply today, it has vast potential around the world and an important role to play in the broader energy system. Offshore wind can drive down CO2 emissions and air pollutants from electricity generation. It can also do so in other sectors through the production of clean hydrogen and related fuels. The high system value of offshore wind offers advantages that make a strong case for its role alongside other renewables and low-carbon technologies. Government policies will continue to play a critical role in the future of offshore wind and  the overall pace of clean energy transitions around the world.
