As the largest carbon sink on Earth, our ocean is the unsung heroes of the fight against emissions and climate change. They absorb a quarter of all carbon dioxide emissions and 90% of the excess heat these emissions cause.
What if we could make the ocean absorb even more CO2 from our atmosphere? This is the concept behind Direct Ocean Capture (DOC).
What is Direct Ocean Capture?
While the world’s drive to reduce CO2 and other greenhouse gas emissions continues, mitigating new emissions alone will not take us to net zero, according to studies referenced by the Intergovernmental Panel on Climate Change (IPCC), which monitors progress towards the targets set by the Paris Agreement. In addition to decarbonizing new emissions, we must find ways to remove existing carbon from the atmosphere – generating “negative emissions”.
One method for doing this is Direct Air Capture (DAC), which draws CO2 directly out of the atmosphere. It is then either stored deeply underground or used in various industrial applications. However, DAC is costly as the concentration of CO2 in the air is relatively low.
Direct Ocean Capture (DOC) is similar to DAC in that it removes dissolved carbon directly from seawater using a range of electrochemical processes. The treated seawater is then returned to absorb more CO2 from the atmosphere. The ocean contains 150 times more carbon dioxide than the atmosphere, making DOC potentially more efficient and lower-cost than DAC...."
