Georgia Power, a utility company, has completed a successful trial using a 50% hydrogen blend to operate a natural gas turbine at its McDonough-Atkinson plant in Georgia, United States. Japan's Mitsubishi Power was responsible for completing the hydrogen blending on one M501GAC gas turbine unit, resulting in an approximate output of 283MW. The trial showcased a 22% reduction in carbon dioxide emissions compared to 100% natural gas operation. This efficiency improvement is attributed to hydrogen's low volumetric density, which requires more gas to produce the same power output. Prior to the 50% blend demonstration, the plant tested various blend percentages, ranging from 5% to 50%. The McDonough-Atkinson plant, which was fully converted to natural gas in 2012, has been expanded to provide power to around 1.7 million homes. The successful trial marks a significant step in exploring the potential of hydrogen blends in power generation, highlighting the environmental benefits and emission reduction capabilities of this technology.
