370-mile hydrogen-electric seaplane set to clean up island hopping


Swiss clean-energy aviation startup JEKTA has announced a partnership with fuel-cell powertrain developer ZeroAvia to extend the flight range and payload capacity of an upcoming electric amphibious passenger aircraft called the PHA-ZE 100.

Swiss clean-energy aviation startup JEKTA has announced a partnership with fuel-cell powertrain developer ZeroAvia to extend the flight range and payload capacity of an upcoming electric amphibious passenger aircraft called the PHA-ZE 100. The amphibious passenger aircraft will feature a composite airframe to nip corrosion in the bud, 10 electric motors/props at 180 kW each spread over the roof-mounted wings for a cruising speed of 135 knots (155 mph), and enough quick-charge battery blocks for one-hour hops "from oceanic islands to Scandinavian fjords" – with 30 minutes in reserve to cope with unforeseen flight plan changes. Initial plans called for battery technology to provide the juice for the electric motors, but the partnership with ZeroAvia will invite hydrogen to the party and enable longer zero-emission flights, with larger payloads.
