The plan depicted in Fig. 1 to produce green hydrogen from seawater using solar or geothermal energy exclusively, which would subsequently add gravity to generate net surplus electricity and fresh water, requires specialized state-of-the art equipment, materials and technologies, and they’re already available. These include earth movers and excavators, efficient solar cells, nearly 100 percent efficient water splitters, specialized materials for hydrogen storage and distribution, and a turbine capable of burning hydrogen 24/7 without fuel cells.

These are not secret technologies, and they’re only the tip of the iceberg. Indeed, intensive research on these and other related topics is ongoing worldwide. Accordingly, it’s not lack of knowhow that’s preventing hydrogen to displace fossil fuels to combat climate change.
