Hydrogen is not a proprietary energy storage mechanism. Does anyone really think they are smarter than Elon Musk and he hasn't thought the pros/cons of hydrogen through and couldn't have already implemented it into the Tesla lineup if it were so great?
It's not "GREEN" if it wastes 50-70% electricity to make it and it's heinously expensive. So what is the value? The argument appears to be that REII can become the proverbial roadside assistance of the EV space since its "portable". This is not a sustainable business plan.
