SS-ISO 27914:2026

This document: a) establishes requirements for the geological storage of CO2 streams in a way that minimizes risk of CO2 losses; 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 enhancing hydrocarbon production; c) includes activities associated with site screening and feasibility investigation, characterization, design and development, operation of storage projects, and preparation for project termination; d) recognizes that the geological characteristics, physical boundaries, management, intrinsic technical risk and uncertainties, of each site are likely to be unique for each project and that intrinsic technical risk and uncertainty will be dealt with on a site-specific basis; e) provides requirements for integrated project management, including elements of risk management unique to the geological storage of CO2 streams; and f) establishes a methodology for quantifying the net mass of CO2 that geological storage projects store in storage unit(s).
