Rolls-Royce has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion. These tests mark another important step towards the commercial introduction of hydrogen solutions to meet the demand of customers for more sustainable energy supply.
Tobias Ostermaier, President – Stationary Power Solutions, Rolls-Royce business unit Power Systems, explained:
“This engine will serve the market demand for hydrogen solutions in the energy transition and will be available to our customers as a reliable and clean power source for gensets and combined heat and power plants.”
The first installation of mtu engines running on 100% hydrogen is already planned for the enerPort II lighthouse project in the German inland port of Duisburg, as part of the development of a climate-neutral energy supply for a new container terminal.
Dr Jörg Stratmann, CEO – Rolls-Royce Power Systems, added: “We see hydrogen as one of the central elements of the energy transition. It can be used for both storage of excess energy and as a fuel, not only for engines but fuel cells and cogeneration plants to generate climate-neutral electricity and heat.”
In times of low demand and high renewable energy generation from wind or solar, for example, the excess energy can be channelled through an electrolyser to convert water to hydrogen, which can later be used as fuel in any number of applications.
