ENGINEERS are a step closer to developing safer, low-pressure fuel tanks for the next generation of electric cars powered by hydrogen fuel cells. They have developed a new material that locks hydrogen gas into cage-like molecules at room temperature, but releases it easily when the fuel is needed. Better still, the material could be customised to store vast amounts of hydrogen safely.
Hydrogen-powered electric vehicles could cut pollution, but a host of problems will have to be overcome before they become commonplace. One of the biggest challenges – apart from making the hydrogen without creating greenhouse gases – is working…
