I have been digging Hydrogen ever since reading this. Imagine a world that is run on H2 generated from solar energy. Fertilizer and Steel manufacturing are going to be revolutionized.
* 10L water to generate 1KG Hydrgoen.
* A 20MW electrolyzer can produce over 8000KG Hydrogen per day
P.S. I have spoken. I wont be able to carry this debate.
