HyPoint Dramatically Extends Zero-Emission Hydrogen Flight Range With New Ultralight Liquid Hydrogen Fuel Tanks
press release
NASA Award-Winning Hydrogen Fuel Cell Pioneer Has Partnered With Hydrogen Tank Maker Gloyer-Taylor Laboratories; New Graphite Fiber Tanks Offer Unprecedented Liquid Hydrogen Storage — As Much As 10x More Capacity Compared With Existing Fuel Tanks
MENLO PARK, Calif., March 29, 2022 (Newswire.com) - HyPoint, the company developing zero carbon-emission turbo air-cooled hydrogen fuel cell systems for aviation and urban air mobility, today announced a partnership with Gloyer-Taylor Laboratories (GTL), an aerospace engineering research and development company, to integrate GTL's advanced carbon composite "BHL™ Cryotank" liquid hydrogen fuel tanks with HyPoint's fuel cell system. BHL™ Cryotanks have demonstrated a 75% mass reduction compared to existing state-of-the-art aerospace cryotanks (metal or composite), 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 distances without refueling. HyPoint also announced that former GE Aviation and Rolls-Royce engineering executive Umeed Ashtiani has joined the company to lead the company's system engineering team and oversee the implementation of the tank technology.
"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. "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. This partnership with GTL goes even further by offering aircraft and eVTOL makers a liquid hydrogen tank that is stronger and lighter than anything else on the market, thereby significantly increasing fuel capacity. 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. 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."
GTL specializes in developing advanced composite prototypes and technologies for aerospace and has won numerous development contracts with NASA, Defense Advanced Research Projects Agency (DARPA), the U.S. Air Force, and others. GTL incorporates many polymer-composite manufacturing processes, including filament winding, hand layup, and fiber placement to produce composite components. GTL has fabricated and tested multiple BHL™ Cryotanks at a range of scales and have been demonstrated to be leak-tight even after repeated cryo-thermal pressure cycles. This technology has achieved TRL 5+ and is compatible with a variety of cryogenic propellants including liquid oxygen, liquid methane, and liquid hydrogen.
The pictured BHL™ Cryotank (held by Zachary Taylor, Vice President of Engineering at GTL) measures 2.4 meters long with a 1.2 meter diameter and weighs 12 kilograms (roughly 26 pounds). When a skirt and vacuum dewar shell are added, the total system weight is 67 kilograms. This particular tank system can hold over 150 kilograms of liquid hydrogen, giving it a hydrogen storage ratio of at least 50% (the weight of stored hydrogen fuel relative to total system weight) which is as much as 10 times greater than current state-of-the-art fuel tanks. An aircraft equipped with GTL dewar tank technology could achieve as much as four times the range of a conventional aircraft using aviation fuel, cutting aircraft operating costs by an estimated 50% on a dollar-per-passenger-mile basis.
"Based on our internal analysis of a De Havilland Canada Dash 8 Q300, which seats 50 to 56 passengers, the standard PW123B engine would typically support a range of 1,558 kilometers. 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. With GTL's tank, it could fly for 8.5 hours or a max range of 4,488 kilometers, indicating that this aircraft could fly three times further with zero emissions by using HyPoint and GTL compared with conventional aviation fuel," said Sergei Shubenkov, Co-founder and Head of R&D at HyPoint. "That's the difference between this plane going from New York to Chicago with high carbon emissions versus New York to San Francisco with zero carbon emissions."
"Similar to the carbon fiber that is used in racing bikes, our carbon-composite technology adds strength and durability while significantly reducing weight. With BHL™ Cryotanks, larger aircraft such as jumbo jets will be able to utilize hydrogen fuel for cross-country flights at least a decade earlier than expected. Similarly, eVTOL and drone makers can significantly extend their range and/or flight time, opening new markets and opportunities," said Paul Gloyer, President and CEO at GTL. "HyPoint is pioneering hydrogen fuel cell technology and we are excited to be working toward a shared vision for zero-emission hydrogen aviation."

US Navy shoots down drone using all-electric laser for the first time
Known as the Layered Laser Defense (LLD), the weapon was designed and built by Lockheed Martin to serve as a multi-domain, multi-platform demonstration system. It can counter unmanned aerial systems and fast-attack boats with a high-power laser—and also use its high-resolution telescope to track in-bound air threats, support combat identification and conduct battle damage assessment of engaged targets.
"Innovative laser systems like the LLD have the potential to redefine the future of naval combat operations," said Chief of Naval Research Rear Adm. Lorin C. Selby. "They present transformational capabilities to the fleet, address diverse threats, and provide precision engagements with a deep magazine to complement existing defensive systems and enhance sustained lethality in high-intensity conflict."
The LLD testing supports a broader effort by the naval research and development community, partnered closely with the fleet, to mature technologies and field a family of laser weapons that can address multiple threats using a range of escalating options. These capabilities range from non-lethal measures, such as optical "dazzling" and disabling of sensors, to destruction of a target.
Laser weapons provide new precision and speed of engagement for naval warfighters. They also offer simplified logistics that are safer for ships and their crews, as lasers are not dependent on the traditional propellants or gunpowder-based ordnance found on ships.
Instead, modern high-power lasers run on electricity, making them inherently safer and able to provide weapon capability as long as a ship has power. This also means the cost per engagement for a laser weapon can be very low, since the only consumable item expended is fuel to run the system.
For years, the Department of Defense (DoD) and all the Services have recognized the promise of directed-energy weapons such as lasers, and continue to prioritize research. Recently, the Under Secretary of Defense for Research and Engineering, the Hon. Heidi Shyu, re-affirmed that directed energy is one of the DoD's critical technology areas.
ONR plays an important role in developing technologies for laser weapons and has fielded demonstration systems for operational experimentation. Notably, in 2014 ONR saw the Laser Weapon System tested successfully aboard the USS Ponce in the Persian Gulf. More recently, ONR fielded the Laser Weapon System Demonstrator aboard the USS Portland in 2021.
Although there's no plan to field the LLD, it offers a glimpse into the future of laser weapons. It is compact and powerful, yet more efficient than previous systems. It has specialized optics to observe a target and focus laser beams to maximum effect, while also incorporating artificial intelligence to improve tracking and targeting.
"LLD is an example of what a very advanced laser system can do to defeat significant threats to naval forces," said David Kiel, a former Navy captain who is a program officer in ONR's Aviation, Force Projection and Integrated Defense Department, which managed the testing. "And we have ongoing efforts, both at ONR and in other Navy programs, to keep building on these results in the near future."
During the recent test at White Sands, the LLD tracked or shot down an array of targets—including unmanned fixed-wing aerial vehicles, quadcopters and high-speed drones representative of subsonic cruise missiles.
"We're proud to say that the Layered Laser Defense system defeated a surrogate cruise missile threat in partnership with the Navy, White Sands Missile Range and Army High Energy Laser Systems Test Facility teams. Lockheed Martin drew best-in-class laser weapon subsystems from across the corporation, including key industry partner Rolls Royce, to support the entire threat engagement timeline from target detection to defeat," said Rick Cordaro, vice president, Lockheed Martin Advanced Product Solutions. "We leveraged more than 40 years of directed energy experience to create new capabilities that support the 21st century warfighter."
Dr. Frank Peterkin, ONR's directed energy portfolio manager, said, "The Navy performed similar tests during the 1980s but with chemical-based laser technologies that presented significant logistics barriers for fielding in an operational environment. And, ultimately, those types of lasers did not transition to the fleet or any other Service.
"Today, ONR coordinates closely with the Navy's resourcing and acquisition communities to make sure we develop laser weapon technologies that make sense for the Navy's requirements to defend the fleet and for operations in the rough maritime environment at sea," Peterkin continued. "It's a challenging problem, but Navy leadership at all levels see potential for laser weapons to really make a difference. The next few years are going to be very exciting as we work with the Navy and joint partners to make the capability we just saw demonstrated by the LLD a reality for the naval warfighter."

Nature-inspired wing demonstrator completes wind-tunnel tests | Airbus
Airbus has completed wind-tunnel testing of its eXtra Performance Wing demonstrator in its quest to quickly test and accelerate new technologies that will decarbonise the aviation industry.
The eXtra Performance Wing project, launched last September, takes inspiration from nature to improve wing aerodynamics and performance that is intended to be compatible with any future aircraft configuration and propulsion system to reduce CO₂ emissions.
"The scaled demonstrator will integrate and fly breakthrough wing technologies using a remote-controlled Cessna Citation VII business jet platform in representative flight conditions," explained Oliver Family, Head of eXtra Performance Wing UK.
"The partly 3D-printed wind-tunnel model - expertly built by the aerodynamics team at Airbus' low-speed, wind-tunnel facility in Bristol - is a scaled-down version of the Cessna jet, incorporating the lightweight, long-span design of the eXtra Performance Wing that will provide the emissions benefits we are striving for."
Initially introduced at a smaller scale through another Airbus project, AlbatrossONE, which tested semi-aeroelastic hinged wings that - like the seabird - unlocked during flight when experiencing wind gusts or turbulence, the eXtra Performance Wing will also examine onboard technologies, like gust sensors, pop-up spoilers and multifunctional trailing edges, to enable the active control of the wing.
"Airbus' state-of-the-art low-speed wind-tunnel is a fantastic way to validate our concepts before flight tests," added Oliver Family. "Our computational aerodynamic analysis capability is world class, and the wind tunnel provides another valuable way to measure the performance and capabilities of the aircraft before flight testing. The technologies we have tested in the Filton wind tunnel - many inspired by biomimicry - will now be rapidly integrated for flight testing."
The Airbus low-speed wind tunnel at Filton, near Bristol, replicates conditions similar to aircraft take-off and landing wind speeds but is also used by external organisations testing F1 cars, ship radar systems, Urban Air Mobility vehicles as well as more conventional aircraft.
The eXtra Performance Wing demonstrator is hosted within Airbus UpNext, a wholly-owned Airbus subsidiary, created to give future technologies a development fast-track by building demonstrators at speed and scale in order to evaluate, mature and validate potential new products and services that encompass radical technological breakthroughs.
