Electrofuels offer an instant, drop-in, zero net carbon replacement for diesel and jet fuel – and an interim path to clean aviation.
Storyboard
The race for zero-carbon aviation
Aviation's climate problem is an energy issue: replacing cheap, lightweight, high-density jet fuel with zero-carbon energy storage that gives usable range without too much of a price, weight or space premium. Battery-electric aircraft may work well in short-range flights, but the most promising technology for longer-range aircraft could be hydrogen.
Airbus is working on a number of hydrogen-fueled clean aircraft, including this blended wing concept.
AeroDelft has revealed a one-third scale prototype of its Phoenix two-seater, which aims to be the world's first liquid hydrogen plane.
The Bye Aerospace eFlyer 800 may be available within four to six years.
Sustainable Aviation Fuel is a name the aerospace industry prefers to biofuel because some biofuels are often relatively primitive or, like palm oil, cause too much environmental damage.
The new ammonia propulsion system uses heat exchanger technology originally developed for Reaction Engines' Skylon spaceplane.
The H3X electric motor design delivers up to three times the power per kilogram of existing motors on the market, offering serious weight savings for aircraft manufacturers.
The maiden voyage of the electric Cessna took place at AeroTEC’s test facility in Moses Lake, Washington.
A De Havilland Canada DCH-8 (Dash-8) Q300 will be retrofitted with a hydrogen fuel cell powertrain to become the world's largest hydrogen aircraft.
These first taxi tests of what is designed to become the world's fastest electric plane are an important early demonstration of its cutting edge propulsion systems.
