What does "CCS" mean in the context of CDR?

UPTAKE Project CDR Glossary

Carbon Capture and Storage (CCS): A process in which carbon dioxide (CO2) is captured, conditioned, compressed and transported to geological storage. This term is commonly applied in the context of fossil CO2 emissions. To count as CDR, however, captured CO2 must come from the atmosphere, either directly from ambient air (see DACCS) or via biomass (see BECCS) or seawater (see DOCCS).

In other words, CCS refers to the process of capturing carbon dioxide formed during power generation and industrial processes and storing it so that it is not emitted into the atmosphere. Carbon capture and storage technologies have significant potential to reduce carbon dioxide emissions in energy systems.

For reasons expressed above (regarding commonly associated with fossil carbon sources) I would prefer that in our work we refer to Geological CO2 Storage (CGS). Perhaps @laurent.drouet we need a specific glossary term on that phrase/acronym? To cover various sources of CO2?

Yes that’s a good idea. Feel free to add an entry to the CDR Glossary, i.e. in the CDR Glossary category.
