Carbon Capture and Storage (CCS) technology was originally developed by the oil industry to recover difficult-to-access deep oil reserves, and was used for Enhanced Oil Recovery (EOR). [2] Although CCS leads to the extraction and combustion of more fossil fuels, carries significant environmental risks, such as carbon dioxide escaping through leaks, is costly and technologically challenging, it is presented as a “climate technology” as a means of capturing climate finance.

The carbon-removal approach would extract CO2 from other gases in the atmosphere by changing it into other forms of carbon (such as carbonate) through photosynthesis or artificial “scrubbing.” This separated carbon then would be either sequestered in biomass at the surface or transported away for storage in the ocean or underground. These include carbon burial, ocean fertilization, biochar production, and scrubbing towers or “artificial trees.”. Carbon burial, more commonly known as carbon capture, utilization, and storage (CCUS), involves the pumping of pressurized CO2 into suitable geological structures (that is, with gas-tight upper layers to cap the buried carbon) deep underground or in the deep ocean (*see* carbon sequestration). The carbon-burial process could also make use of carbon dioxide captured from the atmosphere using scrubbers (*see below* Scrubbers and artificial trees). Direct air captureCollector containers for capturing carbon dioxide from the atmosphere at the Orca plant in Hellisheiði, Iceland. Another form of carbon capture, called direct air capture (DAC), would involve the use of scrubbing towers and so-called artificial trees.

# Startups Begin Geoengineering the Sea. These companies are trying to make the oceans a better carbon sink. The company’s plan is to electrochemically strip carbon dioxide out of the ocean, store or use the CO2, and then return the water to the sea, where it will naturally absorb more CO2 from the air. Two strategies caught **IEEE Spectrum**’s gaze—Captura’s ocean carbon dioxide removal approach, which sucks carbon **out** of the sea, and ocean alkalinity enhancement, which stores carbon **in** the sea. ## How Captura Removes Carbon from the Ocean. There’s no carbon-sequestration facility near Captura’s Hawaii plant, which sits on a volcanic rock beach at the Hawaii Ocean Science and Technology Park. This increases the alkalinity and pH of the ocean, reduces acidification from fossil fuel emissions, and shifts the balance of dissolved inorganic carbon in the sea toward bicarbonate and carbonate ions. * Scaling Carbon Capture to Billions of Tonnes - IEEE Spectrum ›.

Janos Pasztor Executive Director, C2G2 5 Summary Summary This report explores the potential implications which two groups of experimental technologies aimed at managing global climate risk, known as Carbon Removal and Solar Geoengineering, could have for delivery of the Sustainable Development Goals (SDGs). Extensive research gaps exist around the potential implications of deploying Solar Geoengineering or large-scale Carbon Removal and a broad range of topics for further research are suggested, in particular concerning: socio-economic impacts; regional differences; economic impacts; impacts on agriculture and food security; health impacts; environmental impacts; policy instrument design; and governance.
