Eminent physicist Jo Hermans acknowledges that achieving sustainable transport in the post-fossil fuel era will be a huge challenge— but finds that liquid hydrogen could offer a potential solution for future air travel.
Businesses and local governments aren’t doubting climate change, and they aren’t waiting to do something about it. Sea-Tac, USA may become the first airport to fuel all of its flights with biofuel.
Scientists have created a system that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels. The system can convert solar energy to biomass with 10 percent efficiency, far above the 1 percent seen in the fastest-growing plants.
