ZeroAvia and Verne 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 ten percent 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 percent 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.
Founded in California, ZeroAvia is working 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.
