California-based hydrogen fuel cell system developer HyPoint this week announced a partnership with Gloyer-Taylor Laboratories (GTL), to integrate the aerospace engineering research and development company’s advanced carbon-composite trademarked BHL Cryotank liquid hydrogen fuel tanks with HyPoint’s fuel cell system. BHL Cryotanks have demonstrated a 75 percent mass reduction compared with existing metal or composite aerospace cryotanks, allowing hydrogen aircraft and eVTOL makers to store as much as ten times more liquid hydrogen fuel without adding mass. As a result, aircraft can travel longer distances without refueling.
According to HyPoint's analysis of a De Havilland Canada Dash 8-300 regional airliner, which seats 50 to 56 passengers, the standard Pratt PW123B engine would typically support a range of 1,558 kilometers (847 nm). By implementing HyPoint’s system and a standard liquid hydrogen tank, the same aircraft could achieve five hours of flight time or a max range of 2,640 kilometers (1,427 nm), claimed Sergei Shubenkov, the company's co-founder and head of R&D. “With GTL’s tank, it could fly for 8.5 hours or a max range of 4,488 kilometers [2,425 nm), indicating that this aircraft could fly three times further with zero emissions by using HyPoint and GTL compared with conventional aviation fuel,” he stated.
