Could this help reignite hydrogen as a renewable fuel?
Though hydrogen fuel eliminates tailpipe pollution, most hydrogen fuel is made from natural gas, a fossil fuel. It is possible to make it from a cleaner source: water. With electrodes in water, electricity can split the hydrogen from oxygen, giving you pure hydrogen. But until now, the processes have relied on purified freshwater, which is expensive. For the use of hydrogen fuel to scale up, we need a different source, one that’s cheaper and doesn’t use up water we could be drinking instead.
