Swiss company Jetka has announced a groundbreaking partnership with ZeroAvia to enhance their Passenger Hydro Aircraft Zero Emission 100 (PHA-ZE 100) amphibious aircraft. The initial battery-electric powertrain concept will now include hydrogen propulsion, thanks to ZeroAvia's technology, enabling longer and emission-free travel. This move aligns with the vision of creating zero-emission amphibious flights, with Jetka CEO Val Miftakhov expressing confidence in hydrogen-electric propulsion's role in the market. The new variant of the aircraft will feature a fuel-cell system converting hydrogen into electricity to power the motors, significantly extending the seaplane's range to 311 or 373 miles and increasing payload capacity by up to a ton. Additionally, operating and maintenance costs are expected to decrease. ZeroAvia's progress with a hydrogen-electric powertrain prototype in a 19-seat aircraft indicates promising developments for the PHA-ZE 100 integration. Jetka envisions the PHA-ZE 100 transforming travel across archipelagoes with reduced noise and pollution compared to conventional aircraft, highlighting its environmental advantages. The aircraft's versatility is showcased through seven configurations, including economy jets, VIP models, and options for medical or cargo transport. While Jetka has not provided a specific timeline for the hydrogen-powered PHA-ZE 100 launch, customers can expect deliveries of the battery-powered version by late 2028. The innovation in hydrogen-electric propulsion opens up new possibilities for sustainable aviation, offering a glimpse into the future of environmentally friendly air travel.
