GenH2 and ZeroAvia to develop liquid H2 technologies for airports

GenH2 has executed an MoU with H2-electric propulsion developer ZeroAvia to develop liquid H2 aviation infrastructure solutions for use in airport environments. ZeroAvia is developing the first practical zero-emission aviation powertrain to provide scalable, truly clean aviation by replacing conventional combustion engines. ZeroAvia’s H2-electric engine uses fuel cells to generate electricity from H2 fuel, before using that electricity to power electric motors that turn the aircraft propellers.

The company is first targeting retrofit of its H2-electric engines with existing fixed-wing and rotorcraft airframes to reduce time to market, while also partnering with clean-sheet designers. ZeroAvia plans for certification of its ZA600, 600 kW 9-19 seat engine as early as 2025, before certifying the ZA2000 engine for up to 80 seat regional turboprops by 2027.

GenH2 offers H2 liquefaction, storage and dispensing systems ranging from 20 kg/d up to 5000 Kg/d that are capable of working airside as a ground support refueling unit and as a primary source of LH2 fuel in support of airport operations. GenH2’s technology allows liquid H2 utilizers to break traditional geographic constraints so that they can get liquid on demand and wherever their businesses require.

“We are excited to have the opportunity to collaborate with ZeroAvia to develop airside LH2 infrastructure solutions that will establish the foundation for dedicated ground support for ZeroAvia aircraft,” said Greg Gosnell, CEO of GenH2. “ZeroAvia is a leader in zero-emission aviation and has proven H2 is the likeliest fuel source for zero-emission propulsion. The combination of the technologies from ZeroAvia and GenH2 will speed time to market and accessibility for aviation advanced clean energy.”

“Today, aviation is the fastest-growing source of greenhouse gas emissions, and without radical change, its share of global climate impact is expected to be more than a quarter of all human activity by 2050,” said Arnab Chatterjee, Vice President of Infrastructure, ZeroAvia. “We are excited to partner with GenH2 because their liquefaction capability will further support our mission in demonstrating that H2-electric propulsion is the only way to scale truly clean aviation for commercial use.”
