The new ISO standard, ISO 27914:2017 Carbon dioxide capture, transportation and geological storage — Source: DNV GLGeological storage, represents an international consensus on the requirements for the safe and effective storage of CO₂ in geological formations.

A recommended practice from DNV GL certification body provides guidance on safe and reliable design, construction and operation of pipelines intended for large-scale transportation of CO₂. The recommended practice enables compliance with the requirements in the new ISO standard, ISO 27913:2017 Carbon dioxide capture, transportation and geological storage — Pipeline transportation systems.

The DNV GL certification framework provides additional clarity about the requirements an operator should meet — and offers a recipe for how to meet them — at different points in the lifecycle of a geological storage project. It thus improves investor predictability and decreases both capex and opex risks.

The updated recommended practice for design and operation of CO₂ pipelines helps implement the new ISO standard. It is based on new knowledge gained from the CO2PIPETRANS joint industry project, which was completed in 2016, with specific focus on dense phase CO₂ model validation, fracture arrest and corrosion.
