To mitigate the effects of climate change, new technologies will increase the carbon dioxide (CO2) absorption capacity of the oceans, which are already responsible for absorbing one-third of the CO2 produced since the First Industrial Revolution.
This was stated at the online forum “Atmospheric CO2 capture: technologies for a sustainable future” by international experts from prestigious universities such as Oxford, Columbia, and Granada.
Rosalind Rickaby, professor of biogeochemistry and expert on the role of the ocean in CO2 capture at the University of Oxford, stated that the oceans are a major source of CO2 “”magnificent store” and “largest CO2 reservoir,” with 38,000 gigatonnes of this compound in their depths. We have knowledge of where it is deposited.
Sending CO2 to depths where there is less oxygen, pumping these depths so that phytoplankton levels rise to higher levels, or adding fertilizers to the oceans are some of the new techniques to increase the CO2 absorption capacity of the oceans, according to Rickaby, “although they are still under development.”
However, the Oxford University professor urged caution and urged the signing of an international agreement to limit the tools used to store CO2 in the oceans.
Aside from these large bodies of water, there are other options, such as injecting the CO2 trapped in air pockets into the earth’s subsoil.
Alissa Park, the head of Columbia University’s Earth and Environmental Engineering department, stated that “the conversion and reuse of CO2 will play a very important role in making renewable energy increasingly cheaper.”
Park stated that they are also researching how to inject the CO2 captured in air pockets into the earth’s subsoil, and that while the process of capturing carbon dioxide is expensive, it could be used to manufacture new products such as fuels or carbonated beverages, which would stimulate economic investment.
Jean-Paul Lange, senior researcher at Shell Global Solutions in the Netherlands, for his part, stated that biomass could also be a potential CO2 capturer due to its low cost of use, and emphasized that currently “We have the technology to convert it into a wide range of products, including fuels and other chemical products.
