Resumen de: US2022228270A1

Large scale exploitation of Solar energy is proposed by using floating devices which use solar energy to produce compressed hydrogen by electrolysis of deep sea water. Natural ocean currents are used to allow the devices to gather solar energy in the form of compressed hydrogen from over a large area with minimum energy transportation cost. The proposal uses a combination of well understood technologies, and a preliminary cost analysis shows that the hydrogen produced in this manner would satisfy the ultimate cost targets for hydrogen production and pave the way for carbon free energy economy.
