An $11 trillion global hydrogen energy boom is coming. Here’s what could trigger it

At-a-Glance:

Storing fuel in salt caverns isn’t new, but hydrogen’s growing role in decarbonization has revitalized interest in the concept. The Advanced Clean Energy Storage project in Utah aims to build the world’s largest storage facility for 1,000 megawatts of clean power, partly by putting hydrogen into underground salt caverns. The concept is quickly gaining momentum in Europe. To learn more, read An $11 trillion global hydrogen energy boom is coming. Here’s what could trigger it.

Key Takeaways:

  • With the cost of renewables such as solar power falling, green hydrogen is being touted as one part of the energy mix that will lead toward decarbonization, with applications ranging from consumer and industrial power supplies to transportation and spaceflight.
  • By 2050, U.S. demand for hydrogen could increase anywhere from 22 million to 41 million metric tons per year, up from 10 million today, according to a study released this month by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
  • Bank of America believes hydrogen technology will generate $2.5 trillion in direct revenue — or $4 trillion if revenue from associated products such as fuel cell vehicles is counted — with the total market potential reaching $11 trillion by 2050.

Path to 100% Perspective:

Hydrogen has a high potential of becoming the fuel of the future, helping societies move towards decarbonization. Because hydrogen was not used as a power generation fuel in the past, the technologies to combust and use it in different applications need to be developed. Hydrogen burns with air to produce water, without any carbon emissions. It is perfect for use in 100% clean energy portfolios.

How to Build a Green Hydrogen Economy for the US West

At-a-Glance:

Out in Utah, a coal-fired power plant supplying electricity to Los Angeles is being outfitted to eventually be able to run on hydrogen, created via electrolysis with wind and solar power and stored in massive underground caverns for use when that clean energy isn’t available for the grid. This billion-dollar-plus project could eventually expand to more renewable-powered electrolyzers, storage and generators to supply dispatchable power for the greater Western U.S. grid. It could also grow to include hydrogen pipelines to augment and replace the natural gas used for heating and industry or supply hydrogen fuel-cell vehicle fleets across the region. To learn more, read “How to Build a Green Hydrogen Economy for the US West.”

Key Takeaways:

  • The Western Green Hydrogen Initiative (WGHI) is a group representing 11 Western states, two Canadian provinces and key green hydrogen industry partners. WGHI launched in November to align state and federal efforts to create a regional green hydrogen strategy including a large-scale, long-duration renewable energy storage regional reserve.
  • At the heart of this effort are two projects in central Utah. The first is the Intermountain Power Project, a coal-fired power plant operated by the state-owned Intermountain Power Agency, which supplies municipal utilities in Utah and California, including the Los Angeles Department of Water and Power. By 2025, Intermountain will be converted to turbines to supply 840 megawatts of power using natural gas blended with 30 percent hydrogen, a proportion that will rise to 100 percent hydrogen over the coming decades.
  • The second project is the Advanced Clean Energy Storage (ACES) project, which will invest roughly $1 billion to develop a nearby underground salt dome to store compressed hydrogen. ACES will provide up to 150,000 megawatt-hours of energy storage capacity, a scale that dwarfs the lithium-ion battery capacity being installed in California and across the Intermountain West.

Path to 100% Perspective:

Whether green hydrogen can cost-effectively replace natural gas for its myriad current uses will depend largely on the carbon-reduction drivers involved. But it will also require a redefinition of what it’s doing for the broader electrical system, said Jussi Heikkinen, Director of Growth and Development for the Americas division of Wärtsilä Energy Business. Wärtsilä’s engines power about one-third of the world’s cargo ships and a good deal of electricity generation, he said. It’s been making strides in converting its engines to run on 100 percent hydrogen and is developing hydrogen generation projects in the U.S. and Europe. In a study focused on California, Wärtsilä showed that zero-carbon hydrogen, or methane generated with carbon-capture technologies, to fuel power plants is a much less expensive alternative to building the battery capacity needed to cover the final 5 percent to 10 percent of grid power needed to reach its 100 percent carbon-free energy goals. “When there are huge load peaks, cloud cover or unusual weather, these plants kick in, and allow you to build a much smaller battery storage fleet,” he said.
