With more funding available, including from incentive programs, projects that aim to remove carbon dioxide (CO₂) from the atmosphere are seeing a resurgence in popularity, according to Global CCS Institute, an international think thank. Department of Energy announced up to $24 million for research into technology that captures carbon dioxide emissions from the air, a technique called direct air capture (DAC). CCS in New Zealand – Can carbon capture and storage deliver value to New Zealand? Summary report 2011 (external link)Ī number of international partnerships and organisations are working to develop CCS technology and address legal and regulatory issues.Carbon capture is back. In March, the U.S.CCS in New Zealand – Case studies for commercial scale plant: Final report 2010 (external link).The former New Zealand CCS Partnership (whose members included the former Ministry of Economic Development, the former Ministry of Science and Innovation, Solid Energy, and the Coal Association of New Zealand) released 2 reports on the implications of CCS development in New Zealand: Low-emissions economy (external link) - New Zealand Productivity Commission New Zealand CCS Partnership The New Zealand Productivity Commission’s inquiry into a low-emissions economy includes a section on CCS in New Zealand. New Zealand's support for the international development of CCS does not prejudge any decision on whether or when CCS might be undertaken in New Zealand. New Zealand's international approach has been to support the uptake of CCS, in particular by countries that emit large amounts of CO 2. The rationale to adopt carbon capture and storage (CCS) technology in New Zealand is different from other countries.Ĭompared to other countries, New Zealand has relatively few point sources of CO 2 emissions and a far higher renewable contribution to electricity generation. What is CCS (external link) - IEA Greenhouse Gas R&D Programme CCS in New Zealand Find out moreĬarbon capture, utilisation and storage (external link) - International Energy Agency (IEA) Health and safety and environmental considerations will be important to any development – CCS projects are technically complex and are likely to cover large areas, either directly or indirectly. Moreover, CCS technology is very expensive. It is not yet possible to show if CO 2 will behave as expected in storage sites. any previous intensive exploration and drilling activity.ĬO 2 is stored long term in suitable geological formations such as:.porosity and depth of the geological formation.capping layers above the geological formation.Stringent assessment criteria would be applied to find suitable sites, covering aspects such as: InjectionĬO 2 is injected through drilled wells into suitable geological formations. Oxyfuel combustion where thermal fuel is burned in pure oxygen, rather than air, to produce an emission stream of virtually pure CO 2 and water vapour.ĬO 2 is moved by pipelines or ship from its source to a storage site.Pre-combustion capture where the fuel source is oxidised to produce syngas which can then be used in a variety of processes.Post-combustion capture where CO 2 is captured after the fuel has been burned, as in a typical thermal electricity plant.There are different ways to capture the CO 2: CaptureĬO 2 is captured from large, single point sources, such as electricity generation plants and industrial processing plants, such as cement or steel production. There are 4 main steps involved in the CCS process: capture, transportation, injection and storage. collaborated on international research and development.supported research and development in New Zealand.co-ordinated research and policy steering groups.It is thought to be most applicable to reduce emissions from large-scale point sources, such as electricity generated from fossil fuels, and industrial processes including steel and cement production. Carbon capture and storage (CCS) is one proposal to reduce global Carbon Dioxide, CO 2, emissions.
