MAN Energy Solutions announced that its gas-powered, four-stroke engines are “H2-ready” and operable in stationary mode with a hydrogen content of up to 25% by volume in a gas-fuel mix. As such, within the power-plant segment, the company’s MAN 35/44G TS, 51/60G and 51/60G TS gas engines are now designated as H2-ready and capable of exploiting hydrogen to further reduce CO2 emissions.

This hydrogen-combusting capability enables MAN gas engines to meet Level B requirements of the European Engine Power Plants Association’s (EUGINE) H2-readiness standard. With Power-to-X fuels such as synthetic natural gas (SNG), MAN engines can already be operated in a completely climate-neutral way.

The adaptive combustion control (ACC) of the MAN engines reacts fully automatically to varying hydrogen contents in the natural gas and enables operation without loss of efficiency, even with fluctuating hydrogen content. Gas engines already in operation can be retrofitted for hydrogen blend-in by upgrading the automation and adding additional ACC sensors.
