COPENHAGEN, Oct. 29 (Xinhua) -- A Danish research team says they can produce sustainable, green aircraft fuel from ingredients found in Denmark, local news reported Tuesday.
"Our report shows that the technology for producing sustainable aviation fuel in Denmark and in the Nordic countries is available, so that we can start production within a few years," Professor Henrik Wenzel, head of the research team from the University of Southern Denmark, told Danish newspaper Politiken.
The recipe for green aviation fuel includes carbon dioxide, hydrogen, and biogas, and is "a sustainable, attractive and quantity-sufficient solution at a global level," Wenzel said.
The idea is that biogas from manure, straw, food waste or wastewater is supplied to hydrogen, which is obtained by splitting water into oxygen and hydrogen through electrolysis.
The resultant fuel is called "electro fuels," which can be used for climate-friendly alternatives including aviation fuel.
The report was prepared in collaboration with the Nordic aviation industry and engineering consultancy agency NIRAS.
