Hydrogen has been proposed for emissions reductions during take-offs and landings as regulatory authorities, particularly in Europe, advance plans to tax airlines for their emissions. Numbers being discussed are in the range of $50 per seat.

While it is unlikely that an airliner would carry much of the extra weight associated with hydrogen fuel and storage vessels, the HYDRNOL Carrier would be an excellent choice to produce large volumes of hydrogen for co-combustion during take-offs and landings, with only modest weight gains.

In airplanes on the ground, turbines or ancillary sources generate energy for air conditioning. During flight, a part of the energy generated by the main engines is used for a variety of electrical applications as well as for air conditioning. In the future, fuel cells could be an environmentally sound and energy efficient alternative for an aircraft’s electrical requirements. As an auxiliary power supply, a fuel cell would generate electrical power, heat and even potable water for on-board use. Fuel cells would help reduce weight and the risk of power failure by installing several distributed fuel cells.
