Abstract

Kao učinkovite mjere ublažavanja klimatskih promjena, ističu se projekti kaptiranja i skladištenja ugljikovog dioksida (CCS) i projekti kaptiranja, korištenja i skladištenja ugljikovog dioksida (CCUS), koji s povećavanjem tržišne cijene CO2 postaju sve prihvatljivije rješenje. Pravni okvir za regulaciju aktivnosti geološkog skladištenja CO2 u EU-u je Direktiva 2009/31/EZ, koja je prenesena u nacionalno zakonodavstvo svake države članice. Pouzdanost geoloških skladišta predstavlja kritičan element kod mogućnosti realizacije CCS i CCUS projekata, a temelji se na sveobuhvatnoj procjeni rizika. Procjena rizika provodi se kroz: karakterizaciju opasnosti, procjenu izloženosti, procjenu učinaka, te karakterizaciju rizika. Karakterizacija opasnosti uključuje sagledavanje svih komponenata sustava koje predstavljaju potencijalne puteve migracije CO2. Izloženosti CO2 definirana je okolišem u koji je plin migrirao dok se procjena učinaka migriranog plina utvrđuje prema osjetljivosti pojedinih staništa. Karakterizacija rizika predstavlja alat koji se koristi kod definiranja kratkoročnog i dugoročnog integriteta skladišta i daje opis rješenja za smanjenje rizika. U svrhu analize rizika istjecanja CO2 iz geoloških formacija, u radu su definirani mogući putevi migracije CO2 kao glavne opasnosti koje mogu dovesti do njegova istjecanja. Dan je pregled metoda koje se koriste kod karakterizacije rizika, a na primjeru analize rizika za projekte Otway u Australiji i In Salah u Alžiru prikazana je i analizirana njihova primjenjivost.

Abstract (english)

Carbon Capture and Storage (CCS) and Carbon Capture, Utilization and Storage (CCUS) projects are effective climate change mitigation measures that are increasingly acceptable solutions as the market price of CO2 rises. The legal framework for regulating CO2 geological storage activities in the EU is Directive 2009/31/ EC, which has been transposed into the national legislation of each member state. As defined by the Directive, the reliability of geological storage is a crucial element for the possibility to implement CCS and CCUS projects and is based on a comprehensive risk assessment. The risk assessment is carried out through: Hazard Characterization, Exposure Assessment, Impact Assessment, and Risk Characterization. Hazard characterization includes consideration of all system components that represent potential pathways for CO2 migration. Exposure to CO2 is defined by the environment to which the gas has migrated, while assessment of the impact of the migrated gas is determined by the sensitivity of each habitat. Risk characterization is a tool for defining the short- and long-term integrity of the repository and provides a description of risk mitigation solutions for the analysis of the risk of CO2 leakage from geological formations, the paper defines possible migration pathways as the main hazards that may lead to leakage. An overview of the methods used in risk characterization is provided, and their applicability is presented and analyzed on the examples of risk analysis for the Otway in Australia and In Salah in Algeria projects.
