Our solution is unique as it provides a solution to de-carbonise the most difficult to decarbonise sectors.

Prof Weijia Yuan is a fellow of IET and IOP. He directs the Applied Superconductivity Laboratory at University of Strathclyde. He has more than 15 years of research experience in large projects involving cryogenic systems, while dealing with cryogenic manufacturers, as well as end-users. He published more than 100 journal papers in cryogenic and superconductivity areas.
We engage along the entire development chain related to the use of liquid cryogenic hydrogen for aviation propulsion: materials testing, interaction of liquid hydrogen with metals and composites, heat exchangers from coupon to system level, how can H2 molecules escape, aggregate performance of the en tire propulsion system. This allows us to deliver our solutions more efficiently and provide a lower life cycle cost. We are assuming green hydrogen in gaseous form is the start of the life cycle cost and need to show the direct operating cost is comparable for an airline. Our modelling shows the scalability of the solution, and that the larger the aircraft, the more the benefits will accrue.
'The key realization over the last year was the battery as an energy store for airliners didn’t cut it. Not today, not tomorrow, and probably not in the foreseeable future. The alternative energy store that was continuously looked at was Hydrogen, H2. It was the fuel the world’s first jet engine used (H. von Ohain’s He S-1 engine in 1937) and it was the fuel used in the Russian Tu-155 hydrogen research airliner in 1988.
It has some very attractive features like three times higher energy density than jet fuel (batteries have 70 times worse) but also challenges like four times worse volume density and a non-existent production ecosystem for air transport.
