Carbon Capture and Sequestration (CCS)


Funders: CO2CRC
Contact: Rob Funnell

Underground storage or geological sequestration of CO2 is required to reduce future energy related greenhouse gas emissions by 20%.

Carbon capture and storage involves the capturing and separation of CO2 from gases emitted from a stationary greenhouse gas source (i.e., manufacturing or processing plants and gas- or coal-fired power stations), the transport and compression of the CO2, and injection underground into suitable geological formations where it can be safely stored for several hundred to thousands of years.

CCS has the potential to be particularly important for the global energy sector by providing a means of utilising fossil fuel resources until sufficient renewable energy sources are able to be developed. In New Zealand, CCS could play a role in allowing the exploitation of known, and yet to be found, energy resources without contributing significantly to rising greenhouse gas levels.

GNS Science is leading research into how this technology can be safely applied to reduce New Zealand’s greenhouse gas emissions.

GNS Science offers a comprehensive CO2 storage assessment service (selection and characterisation of potential sites) and risk assessment service, including experience in community engagement and education .
