The future of flight is renewable hydrogen

From 20 seat regional trips to over 100 seat long-distance flights, ZeroAvia enables scalable, sustainable aviation by replacing conventional engines with hydrogen-electric powertrains.

Today, aviation is the fastest-growing source of greenhouse gas emissions

graph1-04.png

By 2050, its share of climate impact is expected to be 25-50%. This is why regulators worldwide are pushing for green aviation and net-zero carbon emissions by 2050.

Climate is affected by other substances emitted by aircraft

Significant amounts of NOX, contrails, and particulates matter have a specific warming effect of its own. Released at high altitudes, aviation emissions have 2–4x the impact of comparable ground source emissions. Overall, they amplify the climate impact of aviation, and are mostly overlooked by the industry.

Hydrogen-electric propulsion is the only way to scale sustainable aviation for commercial use

With up to 30 times higher specific energy and lower cycling costs than lithium-ion batteries, and numerous advantages over all other decarbonisation solutions, hydrogen-electric powertrains are the only viable, scalable solution for zero-emission aviation.

​A number of hydrogen's properties make it safer to handle and use than the fuels commonly used today

The first practical hydrogen-electric, zero-emission aviation solution

ZeroAvia’s novel hydrogen-electric powertrain replaces traditional engines on existing fixed wing aircraft, simplifying regulatory issues and reducing time to market.

Zero-emission aviation starts with green hydrogen

Green hydrogen is produced through electrolysis and stored at or near airports, to reduce transportation costs that traditionally drive up the price of hydrogen. The electrolyzers are powered by locally generated renewable energy.

Green hydrogen powers electric propulsion using the fuel cells

Renewable hydrogen stored in tanks is converted to electricity in flight using a fuel cell, which then powers the electric motors.

Hydrogen can be safer than conventional jet fuels

Non-toxic hydrogen and compressed gas storage is more reliable with less severe consequences in the event of failure. Compressed hydrogen tank integrity is superior to conventional liquid fuel tanks. Also, hydrogen has a lower radiant heat than conventional gasoline.

14 X

lighter than air, hydrogen dissipates quickly, unlike liquid fuel vapors

2–3 X

gasoline is more flammable than hydrogen when in the air

18 X

more oxygen concentration required for hydrogen to ignite than gasoline
