Rapid progress in efficiency, performance and clean combustion
For several months, the mtu gas engine has been undergoing bench testing and continuous improvement in terms of efficiency, performance, emissions and combustion using 100 percent hydrogen as fuel. With green hydrogen, these mtu engines can be operated in a CO2-neutral manner in the future. For gas engines already installed, Rolls-Royce offers a conversion solution. Andrea Prospero, an engineer at Rolls-Royce responsible for the development of the hydrogen engine, said:
“We are very pleased with the rapid progress. The very low engine emissions are well below the strict EU limits, no exhaust gas aftertreatment is required.”
Due to the different combustion behaviour of hydrogen compared to natural gas, some engine components including fuel injection, turbocharging, piston design and control, were modified in the test engine. However, by using proven technologies within the Power Systems’ portfolio, such as mtu turbochargers, injection valves, and engine electronics and control, the development of the engine to use hydrogen was advanced quickly and efficiently.
