Hydrogen energy for the aerospace industry

Reducing pollution in airports and in the air

In order to reduce dependence on fossil fuels, and kerosene in particular, clean and sustainable alternative energies must be found. Air Liquide is applying its hydrogen expertise to the aerospace industry and developing more environmentally friendly solutions.

Hydrogen on board aircraft

Hydrogen is a clean source of energy with great potential for applications in the aerospace industry. Air Liquide is developing high-pressure storage systems for liquid and gaseous hydrogen to power fuel cells on board aircraft. Used in a fuel cell, hydrogen combines with oxygen from the air to produce electricity, with water as the only by-product. The electricity produced can be used for a variety of applications, in particular when the aircraft is grounded.

Air Liquide is also developing mobile charging solutions that can be used in airports. The mobile charging station developed by Air Liquide is placed inside a hybrid lorry (petrol/electricity) that can be used to refuel aircraft by parking alongside it. The truck can store up to 300 liters of hydrogen. A compressor and a rack of hydrogen bottles located in the airport can be used to recharge the mobile station.

Hydrogen for airport baggage handling

Ground logistics in airports (forklift trucks, platforms and baggage handling carts) can use hydrogen energy, which reduces pollution. Captive fleets that run on hydrogen increase productivity while reducing emissions at their place of use.

The Group supplies 35 to 70 MPa hydrogen charging stations suitable for fleets of utility vehicles and the specific requirements of the aerospace industry. Integrated directly on site, they can charge vehicles in less than 5 minutes.
