Rolls-Royce Awarded £82.8M for 3 Projects Advancing Liquid Hydrogen Jet Engines

As part of a £113-million (US$136-million) investment from the UK, three projects led by Rolls-Royce will receive £82.8 million (US$100 million) to advance the development of a zero-emission liquid hydrogen combusting jet engine. The funding is being awarded through the ATI Program.

The ATI Program co-funds industry-led innovation in civil aerospace technology and manufacturing, supporting the development of next generation zero carbon and ultra-efficient aircraft, while growing the UK’s competitive position in civil aerospace.

The three projects led by Rolls-Royce are:

Hydrogen Engine System Technologies (HYEST): £14.8-million (US$17.8-million) project to develop technologies and sub-system architecture for the combustor element of a liquid hydrogen gas turbine.

Robustly Achievable Combustion of Hydrogen Engine Layout (RACHEL): £36.6-million (US$44.1-million) project to develop key technologies and integrated powerplant architecture for a liquid hydrogen gas turbine.

Liquid Hydrogen Gas Turbine (LH2GT): £31.4-million (US$37.8-million) project to develop technologies for the delivery of a liquid hydrogen fuel system for a hydrogen gas turbine.

The remaining £30.8 million (US$37 million) from the ATI Program awards package goes to a project led by Vertical Aerospace. Category Enhanced Battery Development (CEBD) is focused on developing a prototype propulsion battery system for aerospace applications, including as part of Vertical Aerospace’s electric vertical take off and landing (eVTOL) aircraft.

' This includes a project by Bristol-based electric aircraft manufacturer Vertical Aerospace to develop high-end, lightweight batteries, as well as projects led by Rolls-Royce to develop the building blocks of a liquid hydrogen combusting jet engine, which would enable flight without the carbon emissions.'


' In addition, the Department for Transport is launching a Call for Evidence seeking views from the sector on how to reach the target for airport operations in England to be zero emissions by 2040. The target was set as part of the government’s Jet Zero Strategy, launched in July last year.'

And Boeing reckon:

' As the Council’s hosts, Boeing will use today’s meeting to demonstrate their new data modelling tool, Cascade, which allows the user to visualise various decarbonisation strategies on the pathway to net zero emissions. Using a variety of datasets, Cascade helps airline operators, policy makers and industry partners make informed decisions on the journey to net-zero by 2050. The tool computes full life-cycle accounting of total climate effects using scenarios for the 5 core strategies: renewable energy, airplane fleet renewal, future aircraft and advanced technologies, operational efficiency improvements and market-based measures and demonstrates that SAF is required to meet the 2050 commitment while continuing to invest in hydrogen, electric and advanced technologies.'

The first transatlantic SAF flight is due this year:

' Virgin Atlantic will also receive government funding to complete the first ever net zero transatlantic flight on 100% SAF. The flight from London to New York will take off from the UK this year.'
