Abstract

Le puits de carbone géologique consiste à « remettre » le carbone dans le sous-sol d’où il a été extrait, afin de réduire les émissions résiduelles incompressibles de CO2. Complémentaire aux puits de carbone terrestre (sols et forêts) et océanique, il devrait jouer un rôle clé pour atteindre la neutralité carbone. 19 opérations de captage et stockage de CO2 (technologie dite CSC, ou CCS en anglais) fonctionnent déjà dans le monde. D’importants efforts de recherche et d’innovation sont menés pour permettre un saut d’échelle et déployer cette technologie partout où ce sera nécessaire. La France, l’Europe et de nombreux pays pensent qu’elle sera incontournable pour parvenir à atteindre les objectifs de l’accord de Paris sur le climat et limiter le réchauffement climatique à +1.5 ∘ C. The geological carbon sink consists of “putting back” the carbon into the subsurface from which it was extracted, in order to reduce incompressible residual CO2 emissions. Complementary to terrestrial (soils and forests) and oceanic carbon sinks, it is expected to play a key role in achieving carbon neutrality. 19 CO2 capture and storage (CCS) projects are already in operation worldwide. Major research and innovation efforts are being carried out to scale up and deploy this technology wherever it is needed. France, Europe and many countries believe that CCS will be essential to achieve the objectives of the Paris climate agreement and limit global warming to +1.5 ∘ C.

二氧化碳捕获与储存:地质碳汇
地质碳汇是将碳“重新”到提取碳的底土中,以减少不可压缩的残余二氧化碳排放。作为陆地(土壤和森林)和海洋碳汇的补充,它应该在实现碳中和方面发挥关键作用。全球已经有19个二氧化碳捕获和储存(CCS)项目在运行。目前正在进行大量的研究和创新工作,以实现规模飞跃,并在任何需要的地方部署这项技术。法国、欧洲和许多国家认为,它将争取实现千年发展目标不可或缺的巴黎气候协定和全球变暖限制在1.5 +∘诉美国地质调查局(The carbon sink”主要由“诺言”The carbon into The back from which it was extracted地下,in order to reduce微调不可减少二氧化碳排放量。它是陆地(土壤和森林)和海洋碳汇的补充,预计在实现碳中和方面发挥关键作用。全球已经有19个二氧化碳捕获和储存(CCS)项目在运行。目前正在进行主要的研究和创新工作,以扩大和部署这项技术在任何需要的地方。法国、欧洲和许多国家认为,CCS对于实现《巴黎气候协定》的目标和将全球变暖限制在+1.5∘C至关重要。

期刊介绍: Created in 1835 by physicist François Arago, then Permanent Secretary, the journal Comptes Rendus de l''Académie des sciences allows researchers to quickly make their work known to the international scientific community. It is divided into seven titles covering the range of scientific research fields: Mathematics, Mechanics, Chemistry, Biology, Geoscience, Physics and Palevol. Each series is led by an editor-in-chief assisted by an editorial committee. Submitted articles are reviewed by two scientists with recognized competence in the field concerned. They can be notes, announcing significant new results, as well as review articles, allowing for a fine-tuning, or even proceedings of symposia and other thematic issues, under the direction of invited editors, French or foreign.
