This diagram shows how green hydrogen produced by electrolysis of seawater using solar energy on rooftops could be used to generate electricity and steam in new plants on suitable mountaintops. The water would be collected, condensed, and fed to cascading turbines on the mountain slopes to generate still more electricity with the goal to recover the energy used to produce the hydrogen in the first place. This system does not use fossil fuels or any other type of energy. The technology to make this real already exists, including a 100% efficient water splitter without enzymes, a turbine capable of burning hydrogen 24/7 directly without fuel cells, and Polyethylene (PE) and epoxy resin anti-corrosive coatings for hydrogen pipelines. This would allow shorelines with abundant sunlight worldwide to out-compete fossil fuels to stop dumping greenhouse gases into the atmosphere.
