Zero-emission aviation firm ZeroAvia has raised $24.3m in new funding to support the development of a 2MW hydrogen-electric engine.

Hong Kong-based venture capital firm Horizons Ventures, an existing investor, led the latest funding round and was joined by new investor British Airways.

Other investors, including Breakthrough Energy Ventures, Ecosystem Integrity Fund, Summa Equity, Shell Ventures, and SYSTEMIQ, also joined the financing.

The financing takes the company’s total private investment to more than $53m while the total funding raised is close to $74m since its formation.

ZeroAvia’s funding comes a few months after the UK Government, through the Department for Business Energy & Industrial Strategy (BEIS), the Aerospace Technology Institute (ATI), and Innovate UK, announced a $16.3m (£12.3m) grant to deliver a 19-seat hydrogen-electric powered aircraft in the market by 2023.

The new funding will accelerate the hydrogen-electric powertrain development for a ten to 20-seater regional aircraft.

ZeroAvia aims to commercialise the engine as early as 2024. The company aims to enter the more than 50-seater commercial aircraft segment by 2026.

The funding will also de-risk the company ambition to power a 100-seat single-aisle aircraft by 2030.

ZeroAvia CEO and founder Val Miftakhov said: “This new funding, in conjunction with our other recent milestones, will significantly accelerate our path to zero-emission solutions for larger regional aircraft at a commercial scale.

“With many airlines lining up and ready to make the shift to zero-emissions, we expect to see wide-scale adoption of this technology.”
