American utilities are increasingly finding the use of what is called green hydrogen made from wind and solar power to reduce emissions from power plants and pipelines.
Initial investment by companies including NextEra Energy Inc.
And Dominion Energy<span> Inc.</span>
It is expected to help commercialize an expensive technology that has been slow to develop despite its ability to provide a stable source of carbon-free power. Utilities and policy makers are increasingly looking at technology to support ambitious renewable-energy targets.</p><div> <p>The Los Angeles Department of Water and Power is spearheading a $ 1.9 billion effort to replace a coal-fired power plant in Utau, the nation's largest municipal utility, which produces natural gas and hydrogen produced from excess wind and solar power Have to walk on The plant, which serves several small utilities and power cooperatives, has long been one of Southern California's most important power sources.

Gas turbines, slated for completion in 2025, will initially burn a 30% hydrogen fuel mixture. Within two decades, they are expected to run entirely on hydrogen to comply with California law, requiring the state's power supply to be carbon-free by 2045.
"From a cost standpoint, it does not compete with natural gas at this point," said Paul Shultes, director of external energy resources for LADPP. But he said that the utility considers the conversion to be a long-term investment requiring legislation and regulators.
And the price of green hydrogen is expected to become more competitive in the coming years.
"The cost is going to go in one direction, and it's down," said Craig Wagstaff, Dominion Energy's senior vice president for Western gas distribution. "It's just a question of how far they're going to go down."
Hydrogen, used in a range of industries, is most often produced from coal or natural gas through carbon-emission processes. The production of green hydrogen, on the other hand, eliminates those emissions by using renewable energy to pull hydrogen atoms from water molecules through a process called electrolysis. Currently, only 1% of the hydrogen produced is green hydrogen.
