Entergy announcement highlights potential demand for green hydrogen

Green Biz:

In late September, U.S. power giant Entergy announced plans to begin exploring the use of hydrogen (H2) in its generation portfolio, as part of a commitment to reach net zero emissions by 2050. This includes producing hydrogen using electrolysis powered by both renewable and nuclear generation, and burning hydrogen blended with natural gas in power plants. The latter part will involve a partnership with Mitsubishi Hitachi Power Systems (MHPS).

This follows on announcements for more than 4 gigawatts of power plant projects across the United States with turbines that can burn a mix of hydrogen and natural gas. All of these projects have contracts with MHPS to supply turbines built for this purpose, and all plan to transition to 100 percent hydrogen.

But more important, most existing hydrogen is produced from natural gas without carbon capture, effectively not providing any decarbonization at all to power generation. The production capacity for clean hydrogen (“green” or “blue”) is much smaller. A recent study by the Institute for Energy Economics and Financial Analysis suggests that all the hydrogen electrolysis projects planned in the U.S. will be able to produce 126,000 metric tons of hydrogen per year.
