WEC Energy and EPRI have announced the successful demonstration of blending hydrogen in a natural gas generator. The project is the first hydrogen power test of a utility-scale, grid-connected reciprocating engine generator in the world.

During two weeks of testing in mid-October, hydrogen and natural gas were tested in blends up to 25/75 percent by volume to power one of the reciprocating engine generating units that serves customers of Upper Michigan Energy Resources, a WEC Energy Group subsidiary. The testing was performed on an 18-megawatt unit that uses a technology known as RICE — reciprocating internal combustion engines. The RICE unit was continually monitored during the test to measure performance, output and emissions data.
