Rolls-Royce has patented a hydrogen gas turbine fuel system that pre-heats hydrogen for stable combustion.
KEY POINTS
- The new Rolls-Royce system uses an auxiliary combustor to heat hydrogen before it enters the main engine.
- Rolls-Royce aims to have hydrogen engines for small and mid-size aircraft by the mid-2030s.
- Airbus has delayed its ZEROe hydrogen aircraft program, pushing back its 2035 target by up to ten years.
- Most hydrogen used today is not carbon neutral, as it is produced from coal and gas, not renewables.
