HydroCoin stands for clean Hydrogen, not for water. And new technologies will produce hydrogen from biomass, wind and solar energy. With optimized electrolysator efficencies. The price for hydrogen at gas-stations vary very much. Hydrogen from fossil source is sold from 9.50 Euro per kg, Hydrogen from regenrative source in sold for up to 16 Dollar per kg in California. But Fuel cell cars are a lot mor efficient with energy than cars with combustion engines. One Kilo of hydrogen can last for more than 100km driving range. So gas price compared to actual cars is already equal. Hydrogen from biomass will turn many farmers on this planet into clean-fuel producers. Combines with optimized electroyser-technology this will be a real chance to turn this world from fossil fuel to clean fuel. It's techology of future for green eco.
