Ocean Air Capture (OAC) is a class of negative emissions technologies that use the ocean’s natural chemical properties to remove and permanently store carbon dioxide from the atmosphere.
Our oceans have absorbed 90% of the heat generated by climate change and ¼ of the excess CO2. While buffering us from the most disastrous effects of climate change for the moment, this is wreaking havoc on ocean ecosystems and the people that rely on them due to increasing ocean acidity and temperature.
Ocean Air Capture helps in two ways – first by taking excess CO2 out of the air through a reaction with a capture chemical and second by converting that CO2 into an “antacid” for the ocean, reducing the acidification caused by climate change.
