Carbon dioxide capture, transportation and geological storage - Geological storage

ISO 27914:2017
a) establishes requirements and recommendations for the geological storage of CO2 streams, the purpose of which is to promote commercial, safe, long-term containment of carbon dioxide in a way that minimizes risk to the environment, natural resources, and human health,
b) is applicable for both onshore and offshore geological storage within permeable and porous geological strata including hydrocarbon reservoirs where a CO2 stream is not being injected for the purpose of hydrocarbon production or for storage in association with CO2-EOR,
c) includes activities associated with site screening and selection, characterization, design and development, operation of storage sites, and preparation for site closure,
d) recognizes that site selection and management are unique for each project and that intrinsic technical risk and uncertainty will be dealt with on a site-specific basis,
e) acknowledges that permitting and approval by regulatory authorities will be required throughout the project life cycle, including the closure period, although the permitting process is not included in ISO 27914:2017,
f) provides requirements and recommendations for the development of management systems, community and other stakeholder engagement, risk assessment, risk management and risk communication,
g) does not apply to, modify, interpret, or supersede any national or international regulations, treaties, protocols or instruments otherwise applicable to the activities addressed in ISO 27914:2017, and
h) does not apply to or modify any property rights or interests in the surface or the subsurface (including mineral rights), or any pre-existing commercial contract or arrangement relating to such property.
The life cycle of a CO2 geological storage project covers all aspects, periods, and stages of the project, from those that lead to the start of the project (including site screening, selection, characterization, assessment, engineering, permitting, and construction), through the start of injection and proceeding through subsequent operations until cessation of injection and culminating in the post-injection period, which includes a closure period. Figure 1 illustrates the limits of ISO 27914:2017.

Capture, transport et stockage géologique du dioxyde de carbone - Stockage géologique

L'ISO 27914:2017
a) établit les exigences et recommandations relatives au stockage géologique de flux de CO2, dont le but est de promouvoir le confinement ŕ long terme et en toute sécurité du dioxyde de carbone ŕ l'échelle commerciale, de maničre ŕ réduire le plus possible les risques pour l'environnement, les ressources naturelles et la santé humaine,
b) s'applique aussi bien au stockage géologique ŕ terre et en mer dans des strates géologiques perméables et poreuses, y compris les réservoirs d'hydrocarbures oů un flux de CO2 n'est pas injecté aux fins de la production d'hydrocarbures ou en vue d'un stockage en association avec la RAH-CO2,
c) englobe les activités liées au tri et ŕ la sélection de site, la caractérisation, l'étude, le développement, l'exploitation des sites de stockage et la préparation en vue de leur fermeture,
d) reconnaît que le choix et la gestion du site sont propres ŕ chaque projet et que les risques techniques et incertitudes intrinsčques seront traités selon une approche spécifique ŕ chaque site,
e) reconnaît que des permis et des approbations devront ętre obtenus auprčs des autorités de réglementation tout au long du cycle de vie d'un projet, période de fermeture incluse, bien que le présent document ne traite pas du processus de délivrance des permis,
f) fournit des exigences et des recommandations pour l'élaboration de systčmes de management, la participation des collectivités et autres parties prenantes, l'appréciation du risque, le management et la communication sur les risques,
g) ne s'applique pas ŕ, ni ne modifie, interprčte ou remplace, tout rčglement, traité, protocole ou instrument national ou international par ailleurs applicable aux activités couvertes par le présent document, et
h) ne s'applique pas aux, ni ne modifie les, droits de propriété ou les intéręts sur les biens en surface ou en subsurface (y compris les droits miniers), ou tout contrat commercial pré existant ou toute disposition afférant ŕ cette propriété.
Le cycle de vie d'un projet de stockage géologique de CO2 couvre tous les aspects, périodes et phases du projet, allant de son lancement (y compris le tri de site, la sélection, la caractérisation, l'évaluation, l'étude technique, l'obtention de permis et la construction), en passant par le début de l'injection et les opérations ultérieures jusqu'ŕ l'arręt de l'injection, et se terminant par la période de post-injection incluant une période de fermeture. La Figure 1 illustre le périmčtre du présent document.

Zajetje, transport in geološko shranjevanje ogljikovega dioksida - Geološko shranjevanje

Standard ISO 27914:2017:
a) določa zahteve in priporočila za geološko shranjevanje tokov CO2 z namenom spodbujanja komercialnega, varnega in dolgoročnega shranjevanja ogljikovega dioksida na način, s katerim se zmanjša tveganje za okolje, naravne vire in zdravje ljudi;
b) se uporablja za geološko shranjevanje na kopnem in na morju v prepustnih oziroma poroznih geoloških plasteh, vključno z nahajališči ogljikovodikov, pri čemer se tok CO2 ne uporablja za namen proizvodnje ogljikovodikov ali za shranjevanje v povezavi s CO2-EOR;
c) vključuje dejavnosti, povezane s pregledom in izbiro lokacije, karakterizacijo, načrtovanjem in razvojem, delovanjem lokacije ter pripravo na zaprtje lokacije;
d) upošteva, da sta izbira in upravljanje lokacije edinstvena za posamezni projekt ter da bosta notranje tehnično tveganje in negotovost obravnavana na podlagi posamezne lokacije;
e) potrjuje, da bosta dovoljenje in odobritev s strani regulativnih organov potrebna v vseh fazah izvajanja projekta, vključno z obdobjem zaprtja lokacije, čeprav postopek izdajanja dovoljenj ni vključen v standard ISO 27914:2017;
f) podaja zahteve in priporočila za razvoj sistemov upravljanja, vključevanje skupnosti in drugih deležnikov, oceno tveganja, obvladovanje tveganj ter obveščanje o tveganjih;
g) se ne uporablja za nacionalne ali mednarodne predpise, pogodbe, protokole ali instrumente, ki se drugače uporabljajo za dejavnosti, obravnavane v standardu ISO 27914:2017, in jih ne spreminja, razlaga ali nadomešča; ter
h) se ne uporablja za lastninske pravice oziroma interese na površju ali pod njim (vključno s pravicami izkoriščanja mineralnih virov) ali katero koli že obstoječo poslovno pogodbo ali dogovor v zvezi s tako lastnino ter jih ne spreminja.
Življenjski cikel projekta geološkega shranjevanja CO2 zajema vse vidike, obdobja in faze projekta, od tistih na začetku projekta (vključno s pregledom in izbiro lokacije, karakterizacijo, oceno, inženiringom, izdajo dovoljenj in gradnjo), prek začetka vbrizgavanja in izvajanja nadaljnjih postopkov do prenehanja vbrizgavanja ter zaključka v obdobju po vbrizgavanju, ki vključuje obdobje zaprtja lokacije.
