In addition, hydrogen fuel cells create electrical power that complements the gas turbine, resulting in a highly efficient hybrid-electric propulsion system. As I’ve discussed before, traditional hydrogen fuel cells can be thought of as batteries that never run flat as long as the H 2 keeps coming. Fuel cells are also cleaner than traditional fuel sources: the only byproduct is warm air, vapor, and H 2 O – water—and its clean enough to drink. Nevertheless, hydrogen fuel cells are a promising advancement already being used in public transport systems and private vehicles around the globe. KLMMore efficient blended-wing body aircraft coupled with hydrogen fuel cells stand to revolutionize the aviation industry.
