Green Hydrogen
As a relevantly new emerging market, 'green' hydrogen does not come from any type of fossil fuel, and instead from the hydrolysis of water by means of electricity obtained from renewable sources such as wind or solar energy. The hydrogen generated can also be sold as fuel for automotive or power generation or any other use that has traditionally used gas. It burns without emitting any CO2 nor does it have to be extracted from the earth like gas. Therefore it is totally green and completely renewable.
