NASA is currently testing a hybrid engine powered by hydrogen, a potentially revolutionary innovation for sustainable aviation. While air travel is responsible for about 2.5% of global CO2 emissions, previous efforts to reduce emissions have been deemed insufficient. Developed under the Hy2PASS project, this engine combines a hydrogen fuel cell with a gas turbine, aiming … Continue reading A Hydrogen Hybrid Engine Tested by NASA: A Breakthrough That Could Finally Reduce Airplane Emissions
