MAN gas engines hydrogen-ready

German engine manufacturer MAN Energy Solutions says its gas-powered engines are hydrogen-ready and operable in stationary mode with a hydrogen content of up to 25 per cent by volume in a gas-fuel mix.

As such, the company’s gas engines are now H2-ready and capable of exploiting hydrogen to further reduce CO2 emissions.

This enables MAN gas engines to meet Level B requirements of the European Engine Power Plants Association’s (EUGINE) H2-readiness standard.

“Flexible and decentralised, gas-fired power plants will play a decisive role for a secure power-supply on the pathway towards 100 per cent renewable energy,” said Gunnar Stiesch from MAN Energy Solutions.

“The CO2 emissions of these power plants can be further reduced by mixing the fuel gas with hydrogen. Green hydrogen is still a scarce commodity and therefore our engines offer operators full flexibility within the scope of the admixture possible in the existing gas network.”

At the same time, MAN is working on future concepts to enable hydrogen fuelling of up to 100 per cent.

Gas engines already in operation can be retrofitted for hydrogen blend-in by upgrading the automation and adding additional ACC sensors.

“The development of a hydrogen economy will take several years, during which time the infrastructure will be upgraded and the production of green hydrogen ramped up,” said Stiesch in conclusion.
