Guest post: How the role of carbon storage has been hugely overestimated
Removing carbon dioxide (CO2) from the atmosphere is widely expected to play a key role in meeting the goals of the Paris Agreement. But this will only be effective for slowing climate change if the CO2 can be stored securely and indefinitely. This requires “geological carbon storage”, where captured CO2 is injected deep underground, where […]
