Abstract: An emitter apparatus is mounted on a marine structure powered by wind or marine hydrokinetic energy to disperse a carbon dioxide sorbent such as sodium hydroxide. The sorbent can be generated by reverse osmosis of seawater with electrolysis of the brine, or delivered from an external supply. Suitable marine structures include offshore wind turbines, marine hydrokinetic generators, offshore oil platforms, merchant vessels, and other fixed and mobile structures. Effective capture is made by dispersing a fine mist or fog of aqueous sorbent from nozzles with a particle size from a nozzle of less than 100 microns. The sorbent reacts with atmospheric carbon dioxide forming carbonates and bicarbonates, which drift and fall to the ocean surface, reducing surface acidity and capturing additional atmospheric carbon dioxide via absorption at the local ocean surface. The resulting carbonates sink to the ocean floor and are there sequestered.

Abstract: The present invention provides a novel floating and renewable energy-powered desalination vessel, which also functions as a wind turbine generator and wave energy generator platform. With energy derived from the wind and waves, the vessel performs reverse osmosis within a vertically positioned cylindrical section extending below a buoyancy chamber. The cylindrical section contains reverse osmosis membranes located above a seawater screening and filtration system, which serve as ballast. The entire vessel and power systems are configured to have the center of mass below the center of buoyancy, forming a vertically stable floating structure with minimum pitch, roll, and wave heave in high sea states. The electric power generated is utilized internally to produce desalinated water or hydrogen from the desalinated water's electrolysis, power an onboard data center, or power delivery to a shoreside power grid.

Abstract: A marine current turbine rotor comprises a hub and fixed and two or more pitchable blade sections configured to reduce bending moment loads on the pitch bearings and enable the use of non-standard, low-cost structural materials for the hub, blades, and pitch shaft. A submersible pitch drive mechanism or linkage in the hub rotates the pitch shaft to cause the pitchable blade section to move to a specified pitch position. The hub cavity is configured to be “wet” without the expense and maintenance requirement of seals to prevent water intrusion, utilizing water-lubricated pitch bearings.

Abstract: Power generated by a wind turbine is applied to drive reverse osmosis (RO) desalination. Rather than discharging the brine back into the ocean, it is concentrated and modified through industrial-scale processes to produce sodium hydroxide (NaOH). Direct air capture of CO2 occurs when liquid NaOH, created from the RO desalination brine, is conveyed to the rotor hub and emitted from the wind turbine blades to react with CO2 in the atmosphere. The power of an offshore wind turbine is used for the onboard production of fresh water to supply shoreside water needs, or water may be electrolyzed to produce hydrogen while adding the vital process of CO2 sequestration to the ocean.

Abstract: A reverse osmosis water production apparatus for use in a body of water includes a first section defining a buoyancy chamber and an elongate second section connected to the first section and configured to define an elongate chamber which extends downward beneath a waterline in use. The elongate chamber is provided with a plurality of elongate reverse osmosis membrane tubes, each tube containing a reverse osmosis membrane. A longitudinal axis of each reverse osmosis membrane tube is substantially parallel with a longitudinal axis of the elongate chamber and the reverse osmosis membrane tubes are arranged around a passage.
