Rolls-Royce and INERATEC to develop eFuels for German data centers

August 6, 2025 |

In Germany, Rolls-Royce and INERATEC have formed a strategic partnership to decarbonize backup power for data centers. Their goal: to replace fossil diesel in emergency power systems with synthetic fuels produced from renewable hydrogen and CO. The collaboration opens up a new and largely overlooked use case for e-Fuels in the digital age—powering critical infrastructure in an increasingly AI-driven world.

The companies intend to use INERATEC’s synthetic e-Diesel, which is produced using green hydrogen and CO, as an alternative to fossil diesel for generators. Initially, the focus will be on German data centers.Rolls-Royce Power Systems plans to support the use of INERATEC’s sustainable fuels in its emergency power systems for data centers. The result is a reliable, cost-efficient, CO-neutral solution to one of the challenges facing digital infrastructure.
