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.

A method of capturing atmospheric carbon dioxide for ocean sequestration, the method comprising the steps of:
- generating electric power via an offshore wind turbine generator comprising a rotor with blades, wherein the offshore wind turbine generator is located in a saltwater environment;
- desalinating salt water from the saltwater environment, using the electric power generated via the wind turbine generator, to produce brine;
- processing the brine, using the electric power and heat generated via the wind turbine generator, to produce sodium hydroxide, wherein processing the brine comprises preheating the brine using the heat generated via the wind turbine generator;
- pumping the sodium hydroxide to the blades, using the electric power generated via the wind turbine generator and centrifugal force provided by rotation of the blades;
- emitting, via the blades, the sodium hydroxide solution into an air stream passing through rotor of the wind turbine generator;
- permitting the emitted sodium hydroxide solution to react, in Earth's atmosphere, with atmospheric carbon dioxide to form sodium carbonate or sodium bicarbonate droplets;
- and
- mixing the sodium carbonate or sodium bicarbonate droplets into the saltwater environment and sequestering the sodium carbonate or sodium bicarbonate within the saltwater environment.
