Denser form of hydrogen storage promises faster refueling and lower costs for hydrogen aviation
ZeroAvia and Verne today announced that they have signed an MOU to jointly evaluate the opportunities for using cryo-compressed hydrogen (CcH2) on-board aircraft and for conducting CcH2 refueling from gaseous hydrogen (GH2) and liquid hydrogen (LH2) sources.
ZeroAvia is a leader in zero-emission aviation, focused on developing hydrogen-electric engines for all types of aircraft as the most environmentally and economically-friendly solution for the industry’s growing climate change impact. Aviation accounts for 10% of all U.S. transportation greenhouse gas (GHG) emissions and three percent of total U.S. GHG emissions, according to the Environmental Protection Agency.
Verne is a hydrogen storage and refueling technology startup focused on solutions using cryo-compressed hydrogen for heavy-duty sectors. Cryo-compressed hydrogen stores gaseous hydrogen at cold temperatures, increasing the energy density of the fuel, which could enable a longer range compared to GH2 powered aircraft.
According to analysis by Verne, cryo-compressed hydrogen can achieve 40% greater usable hydrogen density than liquid hydrogen and 200 percent greater usable hydrogen density than 350 bar gaseous hydrogen. Additionally, the application of cryo-compressed hydrogen promises to significantly reduce cost of densification and refueling time, increase dormancy time relative to LH2 systems, and potentially eliminate venting for pressure management.
ZeroAvia and Verne will assess the potential benefits of scaling CcH2 storage and refueling infrastructure at airports across the world, as hydrogen-electric propulsion scales to support larger and larger aircraft. The two companies will also work together to develop a model for initial airport locations in California.
Verne has developed large hydrogen storage systems exhibiting 4 MWh of storage. Recently, Verne and Lawrence Livermore National Laboratory announced the demonstration of Verne’s 1 MWh CcH2 storage prototype. Verne has received federal grants for the development of its technology, including from ARPA-E. Verne is backed by Amazon’s Climate Pledge Fund, Caterpillar Venture Capital, Collaborative Fund, and other leading investors. As well as rapid work to develop its propulsion technology, ZeroAvia has been active in demonstrating hydrogen airport infrastructure.
Sergey Kiselev, Chief Business Officer, ZeroAvia said: “With our engines just a couple of years from flying passengers and cargo, it is important for us that we find the optimal solutions to support airport hydrogen ecosystems. Increasing storage capacity and refueling speed using novel technologies is an important avenue for scaling up hydrogen aviation, and we’re delighted to work with Verne on assessing the role of cryo-compressed hydrogen.”
Ted McKlveen, Chief Executive Officer & Co-Founder, Verne, said: “Aviation is a massive potential market for Verne, as it becomes clear that hydrogen is critical to tackling the industry’s climate impact. Airports can be centers of hydrogen activity, with co-located hydrogen demand for aircraft, airport ground operations, and on-road commercial transportation. Cryo-compressed hydrogen has a key role in optimizing this ecosystem.”
ZeroAvia is already flight testing a prototype of its ZA600 hydrogen-electric engine aboard a Dornier 228 aircraft at its UK base, and is working to retrofit a prototype of its ZA2000 to a 76 seat Dash 8 400 in the U.S.. Hydrogen-electric engines use hydrogen in fuel cells to generate electricity, which is then used to power electric motors to turn the aircraft’s propellers. The only emission is water.
About ZeroAvia
ZeroAvia is a leader in zero-emission aviation with the mission of delivering a hydrogen-electric engine in every aircraft as the most environmentally and economically friendly solution for addressing the industry’s climate impact. The company is starting with engines to support a 300-mile range in 9–19 seat aircraft by the end of 2025, and up to 700-mile range in 40–80 seat aircraft by 2027. Founded in California, USA, and now with thriving teams also in Everett, WA and the United Kingdom, ZeroAvia has secured experimental certificates to test its engines in three separate testbed aircraft with the FAA and CAA and passed significant flight test milestones. The company has signed a number of key engineering partnerships with major aircraft OEMs and has nearly 2,000 pre-orders for engines from a number of the major global airlines, with future revenue potential over $10bn.
