Rolls-Royce fires up first hydrogen engine but big problem still grounding technologyRolls-Royce and carrier EasyJet have made history after the first test-run of a plane engine powered entirely by hydrogen. On a test site in Wiltshire owned by the UK Ministry of Defence, the engine manufacturer successfully ran a retrofitted Rolls-Royce AE 2100 turboprop using hydrogen fuel. Compressing, storing and flying with pressurised hydrogen gas is a headache for engineers. The current hydrogen market differentiates between “green” and “black” hydrogen, with black hydrogen being extracted from fossil fuels or created using non-renewable sources. In theory, you can make green hydrogen from water and renewable electricity.
