Operators of natural gas power plants in the United States are beginning to explore the integration of hydrogen into their fuel streams as part of efforts to reduce greenhouse gas emissions. This integration includes testing hydrogen cofiring at existing facilities, upgrading turbines to use a blend of natural gas and hydrogen, and ensuring new power plants can operate with a mixture of hydrogen and natural gas. The use of hydrogen in power generation is seen as a way to decrease carbon dioxide emissions, with the process known as cofiring. This initiative has gained momentum due to various federal and state policies promoting hydrogen, such as the EPA's power plant rule and DOE's Hydrogen Hubs program. Several natural gas power plant operators have either announced plans or taken steps towards integrating hydrogen. Duke Energy plans to convert its DeBary power plant in Florida to run solely on hydrogen, while LADWP is considering upgrading units at its Scattergood Generation Station to cofire hydrogen. Additionally, new plants in Utah, Louisiana, and Texas are being constructed with the capability to use hydrogen. These developments align with successful tests conducted at power plants in Ohio, Georgia, New York, Michigan, and Alabama, showcasing reductions in CO2 emissions when hydrogen is part of the fuel blend. The gradual but increasing adoption of hydrogen in the US electric power sector signifies a positive shift towards cleaner energy generation.
