[USA] US electric power sector explores hydrogen cofiring at natural gas-fired plants

On September 12, 2024, the Energy Information Administration (EIA) published an analysis of hydrogen plans at US power plants, describing how natural gas plant operators have taken steps to integrate hydrogen into their fuel streams. [1] The operators took or announced plans to take certain steps, such as testing cofiring hydrogen at existing facilities, upgrading existing turbines to use a blend of natural gas and hydrogen, and incorporating the capability to use a blend of natural gas and hydrogen to build new natural gas power plants. Natural gas composed 43% of electricity generation in the US in 2023, but hydrogen is not yet prevalent or regularly used in plants where it has been tested. The process of burning a blend of hydrogen with natural gas to create electricity is known as cofiring. As the percentage of hydrogen by volume in the blend increases, carbon dioxide emissions decrease. Several policies at the federal level aimed at lowering GHG emissions have garnered interest in hydrogen; the US Environmental Protection Agency recently updated the power plant rule, the US Department of Energy released its Hydrogen Hubs program, and the Inflation Reduction Act provides production tax credits, all of which support the emerging hydrogen sector.
