HyPoint
HyPoint is in an aviation propulsion class of its own. That’s because this company has developed a zero-emissions hydrogen fuel cell system to power electric vertical takeoff and landing (eVTOL) aircraft, a system that has won a 2020 NASA iTech award. The fuel cells generate power that can be used to run electric motors.
“HyPoint’s revolutionary approach utilizes compressed air for both cooling and oxygen supply to deliver a high- temperature fuel cell system that is three times lighter than existing fuel cell systems — representing a total weight reduction of more than 60%,” explained HyPoint founder and CEO Alex Ivanenko. “Testing and modeling have shown that HyPoint’s system can achieve up to 2,000 watts per kilogram of specific power, which is more than double the power-to-weight ratio of traditional hydrogen fuel cells systems and up to 1,500 watt-hours per kilogram of energy density, enabling longer-distance journeys.”
In August 2021, HyPoint partnered with Piasecki Aircraft to codevelop hydrogen fuel cell systems for eVTOL applications including its PA-890 Compound eVTOL helicopter. If successful, the PA-890 will become the first-ever hydrogen-powered manned helicopter.
Also last August, HyPoint announced a new partnership with global chemical company BASF to develop a cutting-edge hydrogen fuel cell membrane that will ultimately increase HyPoint’s system level power significantly, as well as increase durability and operating temperature. The new system will be able to deliver at least 3,000 w/kg of specific power — a 50% increase — that’s enough to satisfy the requirements of virtually any eVTOL.
“In March 2022, HyPoint announced a partnership with Gloyer-Taylor Laboratories to integrate GTL’s carbon-composite liquid hydrogen tanks with our hydrogen fuel cell system,” Ivanenko said. “The tanks have demonstrated a 75% mass reduction compared to existing state-of-the-art

aerospace cryotanks, enabling hydrogen aircraft and eVTOL makers to store as much as 10 times more liquid hydrogen fuel without adding mass. As a result, aircraft can travel longer.”
