ZeroAvia and Verne join forces to explore the potential of cryo-compressed hydrogen (CcH2) for aviation, promising faster refueling and cost reduction. This collaboration aims to address the environmental impact of aviation, which contributes 10% of U.S. transportation greenhouse gas emissions. Verne's innovative CcH2 technology boasts 40% greater usable hydrogen density than liquid hydrogen, marking a significant leap in energy efficiency. The partnership will assess scaling CcH2 infrastructure at airports globally, propelling hydrogen-electric propulsion into larger aircraft territories.


In a groundbreaking collaboration, ZeroAvia and Verne have inked an MOU to delve into the possibilities of cryo-compressed hydrogen (CcH2) for on-board aircraft and refueling operations. With a shared vision of revolutionizing aviation, the partnership seeks to usher in faster refueling processes and cost reductions, addressing the pressing environmental concerns associated with the industry.

ZeroAvia, a trailblazer in zero-emission aviation, is at the forefront of developing hydrogen-electric engines for various aircraft types. The urgency arises as aviation accounts for a substantial 10% of all U.S. transportation greenhouse gas emissions and 3% of total U.S. greenhouse gas emissions, as reported by the Environmental Protection Agency.

Verne, a startup specializing in hydrogen storage and refueling technology, focuses on cryo-compressed hydrogen solutions for heavy-duty sectors. The innovative CcH2 storage method involves storing gaseous hydrogen at cold temperatures, substantially increasing the energy density of the fuel. Verne's analysis reveals a remarkable 40% greater usable hydrogen density than liquid hydrogen and a staggering 200% greater usable density than 350 bar gaseous hydrogen.

The advantages extend beyond density improvements. Cryo-compressed hydrogen presents a potential reduction in densification costs, quicker refueling times, increased dormancy compared to liquid hydrogen systems, and a prospect to eliminate venting for pressure management.

ZeroAvia and Verne's collaboration isn't limited to technical exploration; it encompasses a comprehensive assessment of scaling CcH2 storage and refueling infrastructure at airports worldwide. This strategic move aligns with the escalating demand for hydrogen-electric propulsion to accommodate larger aircraft. Initial airport locations in California will serve as a model for this ambitious endeavor.

Verne, backed by influential entities such as Amazon's Climate Pledge Fund and Caterpillar Venture Capital, has made significant strides in developing large hydrogen storage systems. The company's 1 MWh CcH2 storage prototype, demonstrated in collaboration with Lawrence Livermore National Laboratory, showcases the potential of this groundbreaking technology.

Sergey Kiselev, Chief Business Officer at ZeroAvia, emphasizes the importance of finding optimal solutions for supporting airport hydrogen ecosystems. The collaboration with Verne is a strategic move to enhance storage capacity and refueling speed, crucial for scaling up hydrogen aviation.

Ted McKlveen, CEO & Co-Founder of Verne, sees aviation as a massive potential market for the innovative CcH2 technology. Recognizing hydrogen's critical role in tackling the industry's climate impact, he envisions airports becoming hubs of hydrogen activity, catering to aircraft, ground operations, and on-road transportation.

ZeroAvia is already making strides in hydrogen-electric engine development, flight testing prototypes, and retrofitting aircraft for sustainable aviation practices. As both companies synergize their expertise, the partnership holds the promise of transforming aviation by optimizing the hydrogen ecosystem and paving the way for a more sustainable future.


ZeroAvia and Verne's collaboration marks a pivotal moment in the aviation industry's journey towards sustainability. The exploration of cryo-compressed hydrogen introduces a new era of energy efficiency, promising faster refueling and cost reductions. With a focus on scaling infrastructure and addressing environmental concerns, this partnership positions both companies at the forefront of revolutionizing aviation, emphasizing the urgent need for cleaner, more efficient flight technologies.
