Aquifer could store third of UK’s annual emissions

National Grid has revealed initial results from test drilling at a saline aquifer due to be used by some of the UK’s first carbon capture and storage schemes

A saline aquifer off the Yorkshire coast could store 200 million tonnes of CO2, according to National Grid, which released initial test drilling results in August.

That is equivalent to a third of the UK’s annual emissions.

The news is significant for the viability of carbon capture and storage (CCS) in the UK as saline aquifers will be needed to store CO2 as well as depleted oil and gas wells. But none have so far been fully assessed.
