Taking the heat out of aviation.

Cleaner, greener flight is within reach.

Decarbonising the aerospace industry is one of the planet’s biggest challenges. Our technology is a key enabler in this hard to abate sector, providing significant efficiency improvements to current propulsion and aircraft architectures. Our unique heat management technologies address the challenges of all future net zero systems (hybrid-electric, fully electric, hydrogen fuel cell and hydrogen gas turbine).

Lightweight, compact, and more efficient, enabling you to revolutionise the way you manage heat in flight.

Our game-changing heat transfer technologies make zero-carbon emission aviation possible.



Hydrogen Preheater


Hydrogen Preheater

Project FRESSON.

We are providing the thermal management for the Cranfield Aerospace Solutions-led Project FRESSON consortium, enabling zero emissions aviation.  Our heat management technologies are a key enabler in delivering the world’s first, truly green, hydrogen fuel celled powered commercial passenger aircraft.

Reaction Engines joins ATI projects RACHEL and LH2GT.

With the help of Reaction Engines’ world-leading thermal management expertise, the projects aim to develop cutting-edge technologies that will enable the development of zero-carbon aircraft propulsion systems.

Thermal Management for Hybrid Electric Regional Aircraft (TheMa4HERA).

We are part of a consortium researching and developing components and architectures to overcome the thermal management challenges faced by next-generation narrow body and regional, hybrid-electric aircraft.

Reaction Engines joins Honeywell-led Project NEWBORN.

Using Reaction Engines’ heat exchanger technology, the consortium will develop an aerospace-qualified megawatt-class hydrogen fuel cell propulsion system which will be a critical enabler to reduce aircraft emissions.

Transformative technology to enable zero-carbon aviation.
