Rolls-Royce, based in Bristol, has commenced work on a groundbreaking engine test site at NASA Stennis Center in Mississippi to conduct full-scale gas turbine hydrogen testing. The project, announced at the Farnborough International Airshow, involves a partnership with easyJet and aims to explore hydrogen's potential in aviation decarbonization. This development at NASA Stennis will be the third test stand for Rolls-Royce, showcasing the company's continuous commitment to sustainable aerospace solutions. The testing will focus on integrating technologies for 100% hydrogen fuel operation on a modified Rolls-Royce Pearl 15 engine, with engineering expertise provided by Tata Consultancy Services (TCS). Rolls-Royce's director highlighted the company's role in driving technologies essential for achieving net zero emissions by 2050. Moreover, NASA Stennis expressed enthusiasm for collaborating on this innovative endeavor, building on a longstanding relationship with Rolls-Royce. The project's goal is to validate the viability of hydrogen for powering aerospace engines efficiently and safely. Rolls-Royce's hydrogen research is also supported through various programs in the UK, Germany, and the European Union. Notably, in 2022, easyJet and Rolls-Royce successfully ran a modern aero engine on 100% green hydrogen, setting a milestone in sustainable aviation. This ongoing initiative signifies a significant leap towards cleaner air travel and demonstrates the industry's collective efforts to embrace hydrogen for a greener future.
