Capstone Inching Closer To Full Hydrogen Microturbine

Capstone Turbine Corp. has made progress in the development of a hydrogen operable microturbine.

Working in tandem with the U.S. Dept. of Energy’s Argonne National Laboratory, Capstone Turbine has demonstrated that an off-the-shelf Capstone microturbine can operate on a blend of up to 70% hydrogen to natural gas before adding specialized hardware or software.

The next testing stage involves replacing injectors with Capstone’s hydrogen compatible design, which is intended to ensure combustion stability and flashback margin. The testing will increase the hydrogen levels until reaching 100%.
