Is the universe's most abundant element the best alternative to petrol? As Toyota rolls out its first hydrogen fuel cell car, the Down to Earth team explores how this technology can help us stay mobile with zero emissions.
Germany is already betting on hydrogen to help reduce its carbon footprint. The government, together with industry partners, has invested 1.4 billion euros to implement the technology, including 50 refuelling stations by the end of 2015.
France may be lagging behind in its national commitment to hydrogen-fuelled transport, but entrepreneurs and innovators are leading the way. From McPhy’s revolutionary approach to storing the gas in a solid form, to students in Nantes who have built the world’s most energy-efficient fuel cell car, hydrogen is carving itself out a place in the energy mix of the future.
