In Georgia, Georgia Power and Mitsubishi Power have successfully completed a second trial blending hydrogen and natural gas fuels at both partial and full load on an M501GAC natural gas turbine at Georgia Power’s Plant McDonough-Atkinson in Smyrna, Georgia. The demonstration project is the first to validate 50%* hydrogen fuel blending on an advanced class gas turbine, and the largest test of this kind in the world to date, with the 50% blend providing an approximately 22% reduction in CO2 emissions compared to 100% natural gas. Georgia Power said. Several tests were conducted prior to the 50% blend demonstration including multiple blend percentages that ranged from 5% to 50%, and testing occurred across several weeks in May and June, the company added. Last year, the existing gas turbine was converted from steam-cooled to air-cooled, which includes J series combustion technology with proven high hydrogen co-firing capability. Mitsubishi Power completed the hydrogen blending on one M501GAC gas turbine unit, with an approximate one-on-one output of 283 MW. Mitsubishi Power provided full turnkey service for this project including engineering, planning, hydrogen blending hardware, controls, commissioning and risk management. The company partnered with Certarus to source and manage the hydrogen supply and logistics.
