Georgia Power announced it was able to efficiently generate power using a 20% blend of hydrogen with natural gas in a month-long demonstration at one of its plants, which it said could validate the use of existing natural gas infrastructure to lower emissions.

The utility collaborated with Mitsubishi Power Americas Inc. and the Electric Power Research Institute (EPRI) to complete real-world research on how to adapt existing turbines to use low-emission fuel blends. Mixing relatively high concentrations of hydrogen made using renewable electricity with natural gas, Georgia Power said it tested “partial and full-load” generation capabilities at a plant in Smyrna, GA.

In what the groups called “the largest test of this kind to date,” the fuel blend reportedly met generation...
