There exists plenty of geological CO₂ storage potential in the UK, yet there is essentially no deployment of geological GGR at present. Market commitments from the private sector are growing, but still currently are insufficient to achieve scale. Policies are required to create incentives for effective GGR deployment, and address key barriers. This Policy Brief draws from research to identify three key categories of barriers to GGR deployment. It proposes three Policy Bundles to unlock geological GGR deployment at the speed and scale required by the UK’s decarbonisation pathway: a government-sponsored approach to boost early demand for GGR; a market-based approach with complementary supply-side policies, and, a hybrid approach which combines a voluntary GGR market with government guarantees of trading volumes or prices.
