Networks of hydrogen filling stations are now being opened in Europe and parts of the US. Batteries for road transport have attracted most of the recent publicity around renewables and have become the focus of many governments with targets for switching away from petrol and diesel, particularly in cities with air pollution problems. But hydrogen has even greater potential because its only emissions are pure water and warm air. Storage potential What has made hydrogen so attractive is that it can use surplus renewable electricity from wind and solar farms by using electrolysers to produce hydrogen. This is a process of passing an electric current through water and converting it into oxygen and hydrogen. The hydrogen can then be stored. Read More here
