Hydrogen combustion testing

NCCAT is driving the future of hydrogen combustion—pioneering breakthrough technologies that power progress toward global net-zero aviation.

NCCAT is at the forefront of hydrogen combustion research, pioneering work in the development of future technologies aimed at meeting net zero goals. Hydrogen is a promising alternative to traditional fossil fuels due to its high energy content and, with water vapour being the primary byproduct, the fact that many emissions are eliminated – soot, CO, CO2, SOx. As well as presenting a unique opportunity, hydrogen also presents significant challenges for use in aerospace engines.

Higher reaction rates, higher flame speeds and higher flame temperatures mean that hydrogen combustion systems may require the development of completely new combustor architectures. Additionally, the higher flame temperatures can increase the production of nitrogen oxides (NOx), which have a direct negative effect on health and contribute to the greenhouse effect.  

NCCAT’s research aims to develop technologies which will enable hydrogen to be employed as one of the alternative fuels for future aero gas turbine combustion systems. This includes research at increasing Technology Readiness Levels (TRL) and focusses on: 

  • Understanding fundamental behaviour of hydrogen combustion with lab-scale experiments using advanced optical measurements, coupled to the development of validated numerical predictions. 
  • The development of new and novel combustor architectures which maximise the operability range of hydrogen combustion whilst minimising NOx production. 
  • Higher TRL testing using NCCAT’s intermediate pressure and temperature reacting flow facilities to bridge the gap between fundamental research and engine scale applications.  

This involves working closely with industry partners to ensure findings are targeted towards industry objectives. Collaboration is key to driving innovation and achieving a sustainable aviation industry in the UK.
