Up until now, hydrogen is obtained using a great deal of energy. Today, there are increasing indications that it can be found in a purer form in large quantities, continuously renewed in the subsurface. Studies of its natural occurrence in nature that have led to these assumptions also point towards it being a renewable source of energy. In countries like the US, Australia, France and Spain this so-called white hydrogen is gaining momentum which drives exploration forward, while other countries are more skeptic.
