Hydrogen-electric propulsion (HEP) brings aviation significantly closer to zero emission.

Unlike expensive, polluting, and inefficient jet propulsion, HEP creates zero carbon dioxide, NOx, sulphates, hydrocarbons, lead, and particulates (soot). Combined, the environmental and commercial benefits position hydrogen electric-powered flight as a leading solution.

Comparable ranges

Unlike battery electric, HEP delivers ranges suitable for commercial, regional routes.

Fuel savings

Low fuel costs when compared to jet fuel and Sustainable Aviation Fuel (SAF) used in turbine engines.

Local fuel production

Green hydrogen can be produced onsite and locally at a range of scales.

Low maintenance cost

An estimated 60% reduction in engine maintenance costs compared to turbines.

Three reasons why Hydrogen-electric propulsion is the leading solution.

There has been a breakthrough in high-temperature PEM fuel cells.

The next-generation high-temperature PEM fuel cell (HTPEM) breakthrough will unlock useful range and system life for hydrogen-electric aircraft, just as the Lithium-Ion battery did for electric cars. This is akin to when Tesla utilised Panasonic Lithium-Ion battery cells to design the world’s best car battery pack. We are using this technology to develop the world’s lightest fuel cell system for aircraft.

Alternate sustainable flight solutions compromise on emissions, payload, range and cost.

Sustainable Aviation Fuel (SAF) is expensive and can still emit tailpipe carbon dioxide, NOx, sulphates, and particulates (soot), which presents carbon capture challenges. Hybrid systems are complex, with high costs and a minimal emission reduction of ~7% at 800 km. The electric battery range is too short, even with the latest breakthroughs of 500Wh/kg batteries.

Unlocking the most economical way to decarbonise and increase profits.

The turbocharged, next-generation high-temperature PEM fuel cell system will be 6x lighter than automotive solutions and reduces aircraft operating costs by 50%. Hydrogen-electric is the most economical way to decarbonise and increase profits. Stralis is developing in-house solutions for the hydrogen electric propulsion system control and aircraft integration.
