Carbon storage

Human activities can change concentrations of greenhouse gases such as carbon dioxide (CO2) in the atmosphere

The contribution of fossil-fuel combustion to climate change is one of the most significant environmental issues of our time. Carbon capture and storage (CCS) is a developing technology aimed at mitigating the impacts of carbon emissions by capturing the carbon dioxide (CO2) produced from combustion and storing it long-term in deep geological formations. Geological storage involves injecting CO2, generally in supercritical form, into suitable geological strata such as oil or gas formations, saline aquifers, or unminable coal seams, all with requisite impermeable caprocks.

BGS is an international leader in carbon storage research, including:

  • characterisation of underground geological reservoirs and caprocks
  • experimentation in chemical interactions of CO2 with host rocks
  • site monitoring technology and strategies
  • technical guidance on carbon storage policy and regulation

The BGS National Physical Properties and Processes Laboratory and National GeoEnvironmental Laboratory provide state-of-the-art facilities for all aspects of carbon storage research.
