Abstract : This paper explores the feasibility of implementing cryogenic engines in commercial aircraft as a potential solution to reduce greenhouse gas emissions and improve fuel efficiency. Cryogenic engines, which utilize liquid hydrogen (LH2) as fuel and liquid oxygen (LOX) as an oxidizer, offer exceptional efficiency and performance due to their high specific impulse and low environmental impact. The study assumes that the necessary infrastructure for producing, storing, and distributing cryogenic fuels can be developed and scaled to meet the demands of the aviation industry2. Through a combination of theoretical analysis and simulation, this paper evaluates the technical and economic challenges associated with the adoption of cryogenic engines in aircraft, as well as the potential benefits in terms of reduced carbon emissions and operational costs. The findings suggest that while significant hurdles remain, the integration of cryogenic engines into aircraft propulsion systems could play a crucial role in achieving sustainable aviation in the future.
