Hydrogen has a few key things going for it. Firstly, when it burns its burns clean. There are an ideal replacement for fossil fuels. Remember around 20% of all CO2 emissions come from industry.
Hydrogen could radically reduce this figure. For example hydrogen, when removing the oxygen from Iron Ore, creates water vapour rather than CO2.
Hydrogen could also be used as a clean solution for fuelling vehicles as well as heating buildings. Once again its clean usage makes it an ideal candidate.Full Article
