| Abstract: | This brief feature identifies the important role that membranes may play in a so-called hydrogen economy by considering recent developments in technologies that are being used to generate and store hydrogen.In such an economy, hydrogen — the most abundant element in the universe — replaces fossil fuels as the primary source of energy.A shift to a hydrogen economy will have widespread benefits to society by reducing environmental pollution and global climate change, as well as greatly reducing our dependence on sources of non-renewable energy.Furthermore, if hydrogen fuel cells are ever to replace petrol engines in cars, they will need a cheap source of highly pure hydrogen. |
