50% hydrogen blend successfully tested at Atlanta gas power plant
A 50% hydrogen blend has successfully been run in a natural gas turbine during a trial at a US power plant less than 10 miles from downtown Atlanta, Georgia.
Georgia Power and Mitsubishi Power claim the project at the McDonough-Atkinson plant in Smyrna was the “first” to validate a 50% volume hydrogen blending on an advanced-class gas turbine.
The pair said running the system at a 50:50 ratio reduces around 22% of the turbine’s CO2 emissions compared to 100% natural gas. The lower emissions savings are due to hydrogen’s low volumetric density, meaning more gas needs to be used to produce the same power.
