Carbon capture, use and storage
Carbon capture and storage (ccs) refers to a collection of technologies that can combat climate change by reducing
carbon
dioxide (co2) emissions. The idea behind ccs is to capture the co2 generated by burning fossil fuels before it is released to the atmosphere. The question is then: what to do with the captured co2? most current ccs strategies call for the injection of co2 deep underground.
This forms a “closed loop”, where the carbon is extracted from the earth as fossil fuels and then is returned to the earth as co2. How does ccs work?
today, ccs projects are storing over 30 million tons of co2 every year, which is about the amount of co2 emissions created by 6.
Carbon removal technologies are key to reaching the eu 2050 climate targets as renewable technologies only will not be sufficient. While energy efficiency and renewables are in the long term the most sustainable solutions both for the security of supply and climate change mitigation, global greenhouse gas emissions cannot be reduced as they need to be to reach the paris agreement objective, if we do not also use other options such as carbon capture, utilisation and storage. Timing is crucial. About a third of existing coal-fired power capacity in europe will be replaced within the next 10 years. However, internationally, the energy consumption of china, india, brazil, south africa and mexico will lead to a major global demand increase, which is likely to be met in large part from fossil fuels.
Carbon capture and storage (ccs) or carbon capture and sequestration is the process of capturing carbon dioxide (co2) before it enters the atmosphere, transporting it, and storing it ( carbon sequestration ) for centuries or millennia. Usually the co2 is captured from large point sources , such as a chemical plant or biomass power plant , and then stored in an underground geological formation. The aim is to prevent the release of co2 from heavy industry with the intent of mitigating the effects of climate change. Although co2 has been injected into geological formations for several decades for various purposes, including enhanced oil recovery , the long-term storage of co2 is a relatively new concept.
Ondergrondse co2-opslag (internationaal afgekort met ccs van carbon capture and storage), met name in vlaanderen co2-captatie of koolstofcaptatie genoemd, is het ondergronds opslaan van afgevangen kooldioxidegas dat vrijkomt bij de verbranding van ( fossiele ) brandstoffen. Ccs is een techniek waarmee fossiele brandstoffen (bijna) klimaatneutraal kunnen worden toegepast. Door het broeikasgas co2 dat uit de verbranding van deze koolwaterstoffen ontstaat af te vangen en in ondergrondse reservoirs op te slaan komt die co2 niet in de atmosfeer terecht. Toepassing van ccs bij energieopwekking wordt ook wel ' schoon fossiel ' genoemd. Er komen bij toepassing van ccs wel afvalgassen vrij die niet worden opgevangen.
Carbon capture, use, and storage technologies can capture more than 90 percent of carbon dioxide (co2) emissions from power plants and industrial facilities. Captured carbon dioxide can be put to productive use in enhanced oil recovery and the manufacture of fuels, building materials, and more, or be stored in underground geologic formations. Twenty-six commercial-scale carbon capture projects are operating around the world with 21 more in early development and 13 in advanced development reaching front end engineering design (feed). Carbon capture can achieve 14 percent of the global greenhouse gas emissions reductions needed by 2050 and is viewed as the only practical way to achieve deep decarbonization in the industrial sector.
Why do we need carbon capture, use and storage?
The possibility of capturing carbon dioxide greenhouse gas (co2), an approach known as carbon capture and
storage
(ccs), could help mitigate global warming.
The strategy is to trap carbon dioxide where it is produced at power plants that burn fossil fuels and at factories so that the greenhouse gas isn’t spewed into the air. The captured carbon dioxide would then be transported and stored or used in industrial processes. The intergovernmental panel on climate change (ipcc) estimates that catching carbon at a modern conventional power plant could reduce emissions into the atmosphere by approximately 80 to 90% compared to a plant that doesn't have the technology to catch carbon.
Space technologies and data can play a key role in the development of carbon capture, storage, and sequestration services. Satellite navigation (satnav): gnss can be used for locating and geo-referencing new sites of deployment, and for supporting local teams in the implementation of the planned afforestation/ reforestation/ restoration actions. Gnss will also be used to geo- and time- referenced sensor information of deployed iot systems. Satellite communication (satcom): satellite telecommunications will provide connectivity to remote areas with limited terrestrial connectivity, where especially most carbon storage sites, and reforestation/ land restauration actions will be located. This connectivity will be used, for example, to remotely monitor local energy production and geological sensor status and provide in-the-field team with access to needed on-line services.

Co2 kan als grondstof worden ingezet. Ccu-processen hebben betrekking op de afvang en eventueel concentratie van co2, het transport (indien nodig), het gebruik van co2 als grondstof in producten en processen en de end of life-situatie. Er is dus overlap met ccs (carbon capture and storage) in het eerste deel van het traject. Bij de productie van sommige producten zoals ijzer en staal komt naast co2 ook co vrij via de restgassen. Co is reactiever en, omdat het meer energie bevat, ook waardevoller, dan co2. Bij toepassing van co2 als grondstof kan onderscheid gemaakt worden naar direct gebruik en conversie van co2 tot nieuwe producten.
