HyPoint has announced a partnership with Gloyer-Taylor Laboratories (GTL), forging a deal that will provide HyPoint with carbon composite liquid hydrogen fuel tanks that will be integrated with its own hydrogen fuel cell system.
The companies claim GTL’s BHL Cryotanks are 75% lighter than existing state-of-the-art aerospace cryotanks that are made of metal or composite. HyPoint said this allows aircraft manufacturers to store about 10 times more liquid hydrogen fuel without adding weight to the aircraft.
“Reducing weight is the most important factor for enabling longer distance air travel with fewer stops to refuel,” said Dr. Alex Ivanenko, founder and CEO of HyPoint, in a press release. “Our hydrogen fuel cell system offers better specific power performance compared with any alternative available today, opening the door to short-haul zero-emission hydrogen flight and urban air mobility.”
Ivanenko said HyPoint’s partnership with the hydrogen tank maker allows eVTOL developers to tap into a system that could significantly increase energy density, which allows for the development of sustainable vertical lift aircraft with a longer range than aircraft using current battery technology.
To illustrate the potential benefits aircraft developers could experience from adopting this technology, the company said that a BHL Cryotank with a total system weight of 67 kilogram (148 pounds) can hold more then 150 kg (331 lb) of liquid hydrogen, giving it a hydrogen storage ratio — the weight of stored hydrogen fuel relative to the total system weight — of at least 50%. The companies said this means the BHL Cryotank can store about 10 times more liquid hydrogen fuel than existing aerospace fuel tanks.
“By utilizing this new fuel tank technology, longer haul aircraft may be able to utilize hydrogen for the first time while eVTOL makers can effectively multiply their flight range and operational time,” Ivanenko said. “We’re excited to be working with GTL to offer superior alternative power sources and accelerate the adoption of zero-emission hydrogen across the aviation industry.”
