Rolls-Royce Power Systems, a subsidiary of Rolls-Royce Holdings, is working with a consortium of five companies on developing the technologies required for a “highly efficient first-of-a-kind hydrogen combustion engine to drive combined heat and power (CHP) systems.”
The company made the announcement in a press release.
The project, Phoenix (Performance Hydrogen Engine for Industrial and X), will last three years.
It is expected to deliver a technology concept that can be applied to a prototype engine.
The consortium’s goal is to match the electrical and thermal energy output, including power density and efficiency, currently achieved by natural gas combined heat and power (CHP) units in the higher power range up to 2.5 MW.
Rolls-Royce has already produced a gas-powered combustion MTU engine which has the capability to use hydrogen as a fuel. However, the Phoenix project aims to develop a more advanced and efficient next-generation hydrogen engine.

Hydrogen is one of the solutions used by Roll-Royce to make its engine portfolio greener.
“As soon as the availability of green hydrogen is ensured on a large scale, the technology of highly efficient hydrogen cogeneration plants promoted in the Phoenix project will be ready for use,” said Tobias Ostermaier, President of Stationary Power Solutions within Rolls-Royce’s Power Systems division.
The company is working towards developing its engines so that they are compatible with sustainable fuels such as hydrotreated vegetable oil (HVO) and e-fuels.
The German Federal Ministry for Economic Affairs and Climate Protection is bankrolling the project with nearly € 5 million.
