ATLANTA — 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. 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.

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. The conversion provides the benefits of faster startup times, increased turn down capability and decreased maintenance expenses, while also supporting the ability for this successful landmark hydrogen blend testing.

Natural gas currently provides 40 percent of Georgia Power's annual energy generation and has long been a bedrock fuel for the company. Georgia Power continues to work with the Georgia Public Service Commission (PSC) to ensure it can reliably and economically meet the energy needs of a growing Georgia through the longstanding Integrated Resource Plan (IRP) process. The company is currently developing three new Mitsubishi Power simple cycle combustion turbine resources, capable of utilizing hydrogen, at Plant Yates in Coweta County as approved by the Georgia PSC in the 2023 Integrated Resource Plan Update (IRP).

In addition to new natural gas generation, Georgia Power is also investing in existing power plants to better serve Georgia. Notably, the company has proposed upgrades to ten natural gas turbines – both combined cycle and simple cycle – at Plant McIntosh in the 2025 IRP. These enhancements are expected to add an additional 268-megawatts of capacity, helping to meet the projected energy demands from existing infrastructure. Combined with new renewable generation resources such as solar, these initiatives highlight Georgia Power's dedication to reducing carbon emissions while fostering a resilient and reliable energy future and meeting the increasing energy needs of the state.
