The Energy Technoligies Institute report looks at how brine production could help to develop the capacity to deploy CCUS at commercial scale.
Based on the analysis summarised in this report the savings to the UK from deploying brine production as part of a UK CCS rollout implementation strategy in line with that needed to deliver lowest-cost decarbonisation pathways would be at least £2 billion, but would most likely be more. This cost benefit is derived from a combination of:
-
In-store cost reduction from economies of scale by enabling significantly increased storage capacity to reduce unit storage costs (in one example studied this was worth £1 billion over the life of the store - a 33% reduction); and
-
Enhancing the capacity of cheaper stores, thereby obviating the need to appraise and develop more expensive stores (for the limited examples studied this was valued at another £1 billion).
