Hydrogen should take priority over biofuel in aviation: WWF

The aviation industry should focus research and development programmes on liquid hydrogen rather than third-generation biofuels in the quest to reduce carbon dioxide emissions, according to World Wildlife Fund director for global energy policy Stephan Singer.

"Liquid biofuels may come in as the only alternative to oil but there is a vivid debate to look into liquid hydrogen as a long-term solution," says Singer. "Liquid biofuels may provide a short-term solution but they are also carbon-based."
