Hydrogen-electric plane developer ZeroAvia announced it has garnered an additional $30 million in funding from both new and returning investors, including International Airlines Group (IAG). The aviation company’s Series B funding round now totals $68 million, which will be used to get its forty to eighty seat planes into operation by 2026.

ZeroAvia is a zero-emission aviation company focused specifically on planes that utilize hydrogen-electric propulsion. The company currently operates in the US and UK and has experimental certificates for two prototype aircraft from both the CAA and FAA.

The company is working toward zero-emission commercial plane operations with its 600kW powertrain by 2024, targeting nine to nineteen seats and a range of 300 miles. It will be followed by a 2 to 5 mega-watt (MW) version targeting a 700 mile range. The latter is expected to cleanly power planes with forty to eighty seats and ZeroAvia hopes to deliver it in the next four years.

Last October, we shared news that Alaska Air Group, parent to Alaska Airlines, had invested in ZeroAvia to develop future hydrogen-electric planes. In December, Alaska was joined by United Airlines in an investment round totaling $35 million.

Since then, ZeroAvia has added several new investors and has secured additional funding from some airlines already onboard in support of a future filled with hydrogen-electric plane travel.
