Sea Cheetah, a startup based in Miami, is on a mission to revolutionize coastal transport with hydrogen-powered wing-in-ground effect (WiGE) aircraft. These low-flying aircraft can leverage the wing-in-ground effect to achieve extreme efficiency and cost-effectiveness by flying at an altitude just 5% of their wingspan, providing additional lift and range on a given energy source. Sea Cheetah aims to introduce hydrogen fuel into the equation to boost the range and speed of its ocean-skimmers, while also partnering with H3 Dynamics to establish a hydrogen generation, storage, and fueling network. The company's designs feature a unique airframe resembling the Airfish-8, with large pontoons for storing high-volume, low-mass hydrogen fuel. Various versions of the aircraft are planned for passenger and cargo transport, all equipped with fly-by-wire systems for safety and simplified controls to be operated by captains instead of pilots. The potential transition to hydrogen fuel could significantly increase the range of Sea Cheetah's WiGE aircraft, making them a competitive zero-emissions transport option for coastal routes. While the exact impact of hydrogen on the aircraft's range is yet to be determined, the incorporation of hydrogen technology presents promising advancements in sustainable aviation. Despite facing competition from established players like Regent Viceroy Seaglider, Sea Cheetah's innovative approach to hydrogen-powered WiGE aircraft signifies a significant step towards greener and more efficient transportation solutions.
