Mitsubishi Power, Georgia Power, EPRI Complete World’s Largest Hydrogen Fuel Blending at Plant McDonough-Atkinson – QNT Press Release

  • The project demonstrates retrofitting of Mitsubishi Power’s fleet of advanced-class gas turbines to operate on a hydrogen fuel blend.
  • Georgia Power has already reduced carbon emissions by more than 60%, this new project showcases potential for further reductions using existing infrastructure.
  • Dry low NOx hydrogen blending on the M501G gas turbine was executed at the designed 100% natural gas firing temperature, within emissions compliance and without impact to maintenance intervals.
  • Tests included blending 20% ​​hydrogen — an industry first for an advanced-class gas turbine — resulting in an approximately 7% reduction in CO2 emissions.

Mitsubishi Power and Georgia Power, alongside the Electric Power Research Institute (EPRI), this month successfully validated fuel blending of hydrogen and natural gas at both partial and full load on an M501G natural gas turbine at Georgia Power’s Plant McDonough-Atkinson in Smyrna, Georgia . The demonstration project was the first to validate 20%* hydrogen fuel blending on an advanced class gas turbine in North America, and the largest test of this kind to date, with the 20% blend providing an approximately 7% reduction in carbon emissions compared to natural gas.

Georgia Power, the largest electric subsidiary of Southern Company, collaborated with Mitsubishi Power for the landmark testing as part of a continued commitment to new research and development (R&D) to build the energy grid of the future and to reduce carbon emissions across its generation fleet , with Georgia Power having already reduced its carbon emissions by more than 60% since 2007.

The Plant McDonough-Atkinson facility, located less than 10 miles from downtown Atlanta, has served electric customers for more than 80 years and was fully converted to natural gas in 2012 and expanded to power up to 1.7 million homes. It currently operates six state- of-the-art, large-capacity M501G series gas turbines, which deliver high performance and high efficiency, as well as three steam turbines running in three blocks of 2-on-1 combined-cycle configuration.

Mitsubishi Power completed the hydrogen blending on one M501G gas turbine unit with an approximate output of 265 MW by …
