HyPoint partners with GTL to extend world of zero-emission flying composites with ultralight liquid hydrogen tanks

NASA’s award-winning fuel cell pioneer has partnered with carbon fiber storage tank manufacturer GTL to deliver 10 times the capacity of existing hydrogen storage tanks.#hydrogen
This BHL freezer tank is 2.4m long x 1.2m diameter and weighs 12kg.Together with the skirting and vacuum dewar enclosure, the entire system weighs 67 kilograms, but can hold more than 150 kilograms of liquid hydrogen, giving it a storage rate of at least 50 percent, which is as much as 10 times higher than in its current state.-Art composite hydrogen storage tank.Image source: GTL, HyPoint
HyPoint (Menlo Park, CA, USA) is developing zero-carbon hydrogen (H2) fuel cell systems for aviation and urban/advanced air mobility (UAM/AAM).It already supplies hydrogen aviation leaders ZeroAvia (Hollist, CA, USA) and Piasecki Aircraft (Essington, PA, USA).HyPoint announces a partnership with aerospace engineering R&D company Gloyer-Taylor Laboratories (GTL, Tullahoma, Tennessee, US), which has developed a BHL Cryotank carbon fiber composite liquid hydrogen (LH2) fuel tank that has a mass reduction of 75% %.State-of-the-art aerospace cryogenic tanks (metal or composite) available.
HyPoint integrates BHL Cryotank H2 storage with its turbo air-cooled fuel cell system, enabling manufacturers of H2-powered aircraft and eVTOLs to store up to 10 times more LH2 fuel without increasing mass.As a result, the plane can fly farther without refueling.HyPoint also announced that Umeed Ashtiani, former GE Aviation and Rolls-Royce engineering chief, has joined the company to lead its systems engineering team and oversee the implementation of tank technology.
“GTL offers liquid hydrogen tanks that are stronger and lighter than anything else on the market”
“Weight reduction is the single most important factor in enabling long-haul air travel with fewer fuel stops,” said Dr. Alex Ivanenko, founder and CEO of HyPoint. “Compared to any of today’s alternatives, our hydrogen fuels The battery system provides better specific power performance, opening the door to short-range zero-emission hydrogen-fueled flights and urban air mobility. The collaboration with GTL goes a step further, providing aircraft and eVTOL manufacturers with liquids that are stronger and lighter than those on the market hydrogen tanks, thereby significantly increasing fuel capacity. By utilizing this new fuel tank technology, long-haul aircraft may be able to utilize hydrogen for the first time, and eVTOL manufacturers can effectively increase the number of flights, range and operating time. We are delighted to cooperate with GTL, Provide superior alternative energy and accelerate the adoption of zero-emission hydrogen across the aviation industry.”
GTL is focused on developing advanced composite prototypes and technologies for aerospace and has multiple development contracts with NASA, the Defense Advanced Research Projects Agency (DARPA), the U.S. Air Force and others.GTL combines many polymer composite manufacturing processes, including filament winding, hand lay-up and fiber placement, to produce composite components.GTL has manufactured and tested several BHL Cryotank models that have been shown to remain hermetically sealed even after repeated cryogenic-autoclave cycles.The technology has achieved TRL 5+ and is compatible with a variety of cryogenic propellants including liquid oxygen, liquid methane and LH2.
H2 weighing up to 67kg and storing 150kg provides a 50% storage rate – 10 times higher than state-of-the-art H2 tanks.
The BHL cryogenic tank pictured (held by Zachary Taylor, VP Hydrogen Engineering at GTL) is 2.4 meters long, 1.2 meters in diameter, and weighs 12 kilograms (about 26 pounds).After adding the skirt and vacuum dewar housing, the total weight of the system is 67 kg.This particular tank system can hold more than 150 kg of LH2, giving it a storage ratio (the weight of the H2 fuel stored relative to the total system weight) of at least 50% – 10 times higher than the current maximum.Art H2 tank.Aircraft equipped with GTL Dewar technology have four times the range of conventional aircraft using aviation fuel and an estimated 50 percent reduction in aircraft operating costs on a per-passenger-mile basis.
“Based on our internal analysis of the 50 to 56 passenger De Havilland Canada Dash 8 Q300, the standard PW123B engine typically supports a range of 1,558 kilometers,” said Sergei Shubenkov, HyPoint co-founder and head of R&D.“By implementing HyPoint’s system and standard liquid hydrogen tanks, the same aircraft can achieve a flight time of 5 hours or a maximum range of 2,640 kilometers. Using the GTL’s fuel tanks, it can fly for 8.5 hours or a maximum range of 4,488 kilometers, which demonstrates the Compared to that, the plane can fly three times with zero emissions by using HyPoint and GTL,” “That’s the difference between the high carbon emissions of this plane from New York to Chicago and the zero carbon emissions of New York to San Francisco. the difference. ”
With BHL Cryotanks, large aircraft will be able to fly cross-country on H2 fuel, at least a decade earlier than expected.
Paul Gloyer, President and CEO of GTL, said: “Similar to carbon fiber used in racing cars, our carbon composite technology increases strength and durability while significantly reducing weight. With BHL Cryotanks, large aircraft such as jumbo jets Will be able to use hydrogen fuel for cross-country flight at least a decade earlier than expected. Likewise, eVTOL and drone manufacturers can significantly extend their range and/or flight time, opening up new markets and opportunities. HyPoint is pioneering hydrogen fueling Battery technology and we are excited to work towards a shared vision of zero-emission hydrogen aviation.”
