Miami startup Sea Cheetah is pioneering the development of hydrogen-fueled ocean-skimmers for coastal transport. These ground effect aircraft take advantage of flying at extremely low altitudes, leveraging the wing-in-ground effect to achieve exceptional efficiency and range. Sea Cheetah aims to establish a network for hydrogen generation, storage, and fueling in collaboration with H3 Dynamics, potentially revolutionizing zero-emissions transport. Operating within maritime regulations rather than requiring FAA certification, these ocean-skimmers offer a cost-effective alternative for customers, combining the speed of air travel and the efficiency of boats. The incorporation of hydrogen fuel could further enhance the range capabilities of these vessels, making them a compelling option for long-distance travel. The design features advanced aerodynamics with electric propulsion and large pontoons for hydrogen storage. Various configurations are planned, including passenger and cargo transport versions. While the specifics of the hydrogen implementation are yet to be revealed, the potential for significantly extended range is notable. With the ability to avoid the complexities of FAA certification, these hydrogen-powered ground effect aircraft present a promising future for sustainable coastal transportation.
