An offshore vessel embodies a mobile buoyant energy recovery system enabled to extract energy from solar power. An exemplary energy recovery system comprises concentrating solar thermal power systems (CSP) or concentrating photovoltaic power (CPV) systems on the deck of the vessel. Within the vessel hull, ballast water serves multiple purposes. The ballast not only stabilizes the vessel, but also provides reactant for hydrogen electrolysis or ammonia synthesis, or steam for a turbine. For CPV systems the ballast conducts heat as a coolant improving the efficiency and durability of photovoltaic cells. For CSP systems the ballast water becomes superheated steam through a primary heat exchanger in the concentrator. In some embodiments, some steam from the CSP primary heat exchanger or from the CPV coolant system undergoes high-pressure electrolysis of enhanced efficiency due to its high temperature. In some embodiments, the remaining steam that did not undergo electrolysis drives a steam turbine providing electrical current for electrolysis. A secondary heat exchanger takes heat from the steam expelled from an energy storage process to efficiently distill ballast water at a lower temperature thus minimizing corrosion and build-up of scale. A remote control Supervisory Control and Data Acquisition System (SCADA) determines position, navigation, configuration, and operation of the preferably unmanned modular mobile buoyant energy recovery structure based on Geospatial Information Systems (GIS), Velocity Performance Prediction (VPP) models, Global Positioning Satellites (GPS) and various onboard sensors and controls.
