Hydrogen fuel Cell vehicles and Hydrogen for IC Engines Vehicles may be a small part of the entire Green hydrogen game plan, which to begin with may go side by side along with EV for quite sometime due to complexities involved. But the science comes out with solutions - if Green hydrogen is the ultimate goal.
However, there are many othe carbon producing industries such as power plants, fertilisers, Petroleum refining and many others where Green hydrogen theme is playing out very fast- it is not at all a hype.
It is because if we look at the big picture on climate change, Global warming , Ozone layer depletion , the entire Globe is looking towards the Carbon foot print- there is no denying and all the nations are coming together to unanimously agree only one Goal , one vision to move towards Green hydrogen / Renewables as the ultimate source of energy to reduce carbon foot print.
