Tata Consultancy Services (TCS) and Rolls-Royce have successfully [demonstrated](https://www.tcs.com/who-we-are/newsroom/press-release/tcs-rolls-royce-achieve-breakthrough-in-hydrogen-powered-aviation?ref=theleftshift.com) the operation of a modern aero gas turbine across a fully simulated flight cycle using 100% hydrogen.

 "W*e have gained valuable insights into how 100% hydrogen behaves in a modern aero gas turbine across a full flight cycle while validating critical combustion, fuel and control system technologies.* 

*"The learnings from this initiative will support future propulsion innovations, including UltraFan®, and strengthen our confidence that gas turbine technology can continue to play an important role in the future of sustainable flight,"* [*Adam Newman*](https://www.linkedin.com/in/adam-newman-62a65719b/?ref=theleftshift.com)*, Rolls-Royce Chief Engineer, Hydrogen Demonstrator Programme, said.*

The milestone is part of a four-year programme to assess hydrogen’s potential as a future aviation fuel. 

The programme was first announced by Rolls-Royce and easyJet in 2022, with [TCS](https://www.theleftshift.com/tcs-partners-with-vodafone-business-to-accelerate-ai-cloud-and-digital-transformation-in-the-uk/) joining in 2024 as an engineering and technology partner.

During the latest demonstration, a modified aero engine powered entirely by hydrogen completed a simulated flight cycle covering take-off, cruise and landing. 

The tests were designed to validate key technologies required for hydrogen-powered propulsion, including combustion, fuel systems and engine controls.

TCS supported Rolls-Royce across several areas of the programme, including fuel-system and engine-control integration, hydrogen combustion analysis, test preparation, validation, data analytics, risk management and detailed engineering design.

 *“This milestone reflects what becomes possible when advanced engineering is combined with digital capabilities and deep ecosystem collaboration to move breakthrough innovation closer to the real world.* 

*"This achievement marks a significant step forward—demonstrating not just the viability of hydrogen, but the industry’s readiness to translate ambition into execution,”* [*Anupam Singhal*](https://www.linkedin.com/in/anupamsinghal/?ref=theleftshift.com)*, Tata Consultancy Services President, Manufacturing, added.*

The demonstration involved Rolls-Royce and TCS working with easyJet, NASA, the UK Health and Safety Executive (HSE) and other industry partners.

Aviation currently accounts for approximately 2–3% of global CO₂ emissions. Hydrogen propulsion could potentially eliminate in-flight CO₂ emissions when deployed at scale, although significant infrastructure, production and aircraft-design challenges remain.

The companies said the findings will inform future propulsion technologies, including Rolls-Royce’s UltraFan®, and contribute to the aviation industry’s efforts to develop lower-carbon forms of air travel.
