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.
Claims20
A direct air carbon dioxide capture device comprising:
- a wind turbine generator comprising one or more blades;
- a desalination system, wherein the desalination produces brine;
- means for producing an alkaline solution from the brine;
- and
- means for emitting the alkaline solution into an air stream passing through the one or more blades.
A method of capturing atmospheric carbon dioxide for ocean sequestration, the method comprising the steps of:
- generating electric power via a wind turbine generator 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 generated via the wind turbine generator, to produce sodium hydroxide;
- and
- emitting the sodium hydroxide solution into an air stream passing through a rotor of the wind turbine generator.
