Aerospaceā€™s Future Without Jet Fuel

As the world grows increasingly concerned about climate change, the aerospace industry is also exploring ways to reduce its carbon footprint. Aircraft engines are among the biggest contributors to carbon emissions, with jet fuel being one of the primary sources of greenhouse gases.

Green aviation

Several companies and researchers are now working on developing alternative technologies that can power aircraft without relying on fossil fuel-based jet fuel. The field of green aviation is rapidly evolving, with numerous breakthroughs being reported in recent years.

Electric planes

One of the most promising avenues of research is the use of electric aircraft. These planes use batteries to power electric motors instead of jet engines, and have the potential to be much cleaner and more efficient than traditional planes.

Several prototypes of electric planes have already been developed, such as the Airbus E-Fan, which is a two-seater electric aircraft that has successfully flown across the English Channel. However, these planes are still limited in terms of their range and carrying capacity, and much work needs to be done before they can replace traditional jets.

Solar-powered planes

Another technology that is gaining interest is the use of solar-powered planes. These planes harness the power of the sun to generate electricity that can be used to power electric motors.

The most well-known solar-powered plane is the Solar Impulse, which completed a round-the-world journey in 2016. The plane is covered with solar panels and is capable of flying for several days and nights without landing.

Hydrogen-powered planes

Hydrogen fuel cells are another technology being explored for powering planes. These cells generate electricity through a chemical reaction between hydrogen and oxygen, with water being the only byproduct.

One of the companies working on hydrogen fuel cell planes is ZeroAvia, which recently completed a successful test flight of a six-seater plane powered by a hydrogen fuel cell. The company hopes to develop a 50-seater plane that can fly up to 500 miles by 2023.


While there is still a long way to go before jet fuel can be completely replaced by alternative technologies, the progress being made in the field of green aviation is promising. With continued research and development, it is likely that we will see a future where planes are powered by clean, renewable energy sources.
