jointly fund research by Hydrogen South Africa (HySA) into the application of fuel cells on airliners. The initial three-year project, which will be undertaken by HySA Systems Competence Centre at its University of the Western Cape research facility, was launched in Cape Town today.
With demand for air transport doubling every 15 years, the global airline industry will require nearly 30,000 new aircraft (over 100 seats) by 2032. Simultaneously, the dual factors of high jet fuel costs and industry commitments to halve 2005 CO2 emissions levels by 2050 are driving the search for alternative solutions to fossil-fuel based propulsion and energy sources.
With this in mind, Airbus has identified hydrogen fuel cells as a future, emissions-free substitute to small gas turbine engines called Auxiliary Power Units (APUs), which are used for generating on-board electrical power and heat while the aircraft is on the ground. Almost every airliner designed and built since the advent of jet travel in the 1950s, has been equipped with an APU, which is located in the tapered tail cone section of the rear fuselage. Replacing the fossil-fuel powered APUs with hydrogen fuel cells would help achieve the goals of emission-free and low-noise aircraft operation.
“This fuel cell project with HySA Systems Competence Centre and the National Aerospace Centre, is the latest element of Airbus’s Research and Technology initiative with South Africa, which was launched in 2006 and involves collaboration with several of the country’s universities and research institutes.
It underlines our commitment to South Africa, which is a significant market, hosts some of our most important suppliers and is a vital knowledge partner for Airbus” explained Dale King, Airbus’ Senior Manager, Emerging Technologies and Concepts. Besides emission-free and low-noise aircraft operation, fuel cells would reduce the overall weight of aircraft, leading to lower fuel burn and operating costs together with further reduced carbon emissions during flight.
As by-products, hydrogen fuel cells could enable aircraft to generate their own water supplies. They would also have a safety benefit through their ability to generate inerting gas used to reduce flammability levels in aircraft fuel tanks and for supressing any cargo hold fires.
