(Main)Lifecycle risk management for integrated CCS projects
Lifecycle risk management for integrated CCS projects
ISO/TR 27918:2018 is designed to be an information resource for the potential future development of a standard for overall risk management for CCS projects. The risks associated with any one stage of the CCS process (capture, transportation, or storage) are assumed to be covered by specific standard(s) within ISO/TC 265 and other national and/or international standards. For example, the risks associated with CO2 transport by pipelines are covered in ISO 27913. The scope of this document is intended to address more broadly applicable lifecycle risk management issues for integrated CCS projects. Specifically, the focus of this document is on risks that affect the overarching CCS project or risks that cut across capture, transportation, and storage affecting multiple stages. It needs to be noted that environmental risks, and risks to health and safety should be very low for CCS projects provided the project is carefully designed and executed. Risk identification and management is part of the due diligence process. A list of acronyms is included in Annex A. Clause 5 includes an analysis of how a CCS standard could address aspects of risk analysis that apply to all elements of the CCS chain, such as: - risk identification (identifying the source of risk, event, and target of impact)[1]; - risk evaluation and rating; - risk treatment; - risk management strategy and reporting. Clause 6 comprises an inventory of the overarching and crosscutting risks. These include issues such as: - environmental impact assessment; - risk communication and public engagement; - integration risks between capture, storage, and transportation operators, such as risk of non-conformance of CO2 stream to required specifications; - integration risks associated with shared infrastructure (hubs of sources, common pipelines, hubs of storage sites); - risks resulting from interruption or intermittency of CO2 supply and/or CO2 in-take; - risks associated with policy uncertainty; - incidental risks from activities related to the capture, transportation or storage processes without being specifically covered in the respective standards (e.g. management or disposal of water produced as a by-product of CO2 storage). Clause 7 describes implications and considerations for a potential standard on lifecycle risks for integrated CCS projects. [1]As defined in ISO 31000.

ISO/TR 27918:2018(E)
Introduction
Carbon Capture and Storage (CCS) is a process that can mitigate the CO emissions from power plants and
2
other industrial sources of CO . CCS draws on many decades of experience in the electricity generation,
2
industrial gas separation, chemical and manufacturing industries, and oil and gas industries, including
substantial experience with subsurface injection techniques.
Many of the individual processes (or project phases) that are linked together to comprise a CCS chain
have been proven for some time, albeit often in different contexts. Others are still being developed or
adapted to this new application. Additionally, bringing them together in a CCS configuration represents
a new application, with which there is limited global experience to date. As a result, there is an important
need for knowledge development as real experience is gained in the comprehensive application of these
technologies.
As with most technologies, CCS has inherent risks which need to be analysed and managed. Integrated
projects, given their especially long-term and multi-component aspects, impose particular importance
and challenge upon comprehensive risk identification. Risk assessment (detailed risk description and
quantification) is completed using all available data, and assessment refreshed with updated numerical
simulations which enable comprehensive risk analysis throughout the project lifecycle. The project
lifecycle extends across all project phases from business development to site selection through post-
closure. Together, risk identification, assessment, analysis, evaluation, management, and treatment
are integrated into a risk management plan. The risk management plan aids in decision-making by the
owner/operator and, to the extent the results of planning are communicated, aids other stakeholders in
evaluating the project.
Keys to the success of the risk management plan are the integration and iterative application of risk
assessment, risk data, and risk analysis. Risk analysis and numerical simulation help to identify,
estimate and mitigate risks that may arise from CCS projects. These tools are also useful to optimize
the design and operation of the monitoring, verification, and accounting aspects of the projects and can
serve to inform and facilitate more effective site characterization and model improvement. Importantly,
risk tools can be used to shape the design and operation of preventive and remediation options at every
stage in the project lifecycle. Effective risk management communication to stakeholders who may be
affected is crucial to the success of the project. The risk management plan can serve as a key component
of the information handled through the public outreach and communication plan.

Lifecycle risk management for integrated CCS projects
1 Scope
This document is designed to be an information resource for the potential future development of a
standard for overall risk management for CCS projects. The risks associated with any one stage of the
CCS process (capture, transportation, or storage) are assumed to be covered by specific standard(s)
within ISO/TC 265 and other national and/or international standards. For example, the risks
associated with CO transport by pipelines are covered in ISO 27913. The scope of this document is
2
intended to address more broadly applicable lifecycle risk management issues for integrated CCS
projects. Specifically, the focus of this document is on risks that affect the overarching CCS project or
risks that cut across capture, transportation, and storage affecting multiple stages. It needs to be noted
that environmental risks, and risks to health and safety should be very low for CCS projects provided
the project is carefully designed and executed. Risk identification and management is part of the due
diligence process.
A list of acronyms is included in Annex A.
Clause 5 includes an analysis of how a CCS standard could address aspects of risk analysis that apply to
all elements of the CCS chain, such as:
1)
— risk identification (identifying the source of risk, event, and target of impact) ;
— risk evaluation and rating;
— risk treatment;
— risk management strategy and reporting.
Clause 6 comprises an inventory of the overarching and crosscutting risks. These include issues such as:
— environmental impact assessment;
— risk communication and public engagement;
— integration risks between capture, storage, and transportation operators, such as risk of non-
conformance of CO stream to required specifications;
2
— integration risks associated with shared infrastructure (hubs of sources, common pipelines, hubs of
storage sites);
— risks resulting from interruption or intermittency of CO supply and/or CO in-take;
2 2
— risks associated with policy uncertainty;
— incidental risks from activities related to the capture, transportation or storage processes without

4 General information on lifecycle risk management for CCS
4.1 Usefulness and benefits of lifecycle risk management
Overarching, or crosscutting risk management may help inform future investment and regulatory
decisions regarding the risks associated with a CCS project lifecycle. Such evaluations of overarching
lifecycle risk already have been performed for previous CCS projects, either as part of an Environmental
Impact Assessment [Gorgon (Chevron) and Shengli Dongying (SINOPEC)] or as a requirement of the
regulatory or permitting process.
A future International Standard that builds on previous requirements in relevant industries could help
future project developers in meeting permitting requirements and help ensure that risks associated
with a CCS project are comprehensively identified, evaluated, and managed. In addition, it may promote
an appropriate management of risks to health, safety and the environment in areas where regulatory
frameworks are less comprehensive, and it may inform future regulatory developments.
4.2 Defining lifecycle for an integrated CCS project
Most of the organizations that have previously published guidelines or standards for CCS risks have
focused on the lifecycle of the storage component of a CCS project. Figure 1 to Figure 6 present various
lifecycle descriptions from published sources.

Figure 6 — Lifecycle of a CCS project as defined in in the International Standard for Carbon
Dioxide Capture, Transportation, and Storage—Geologic Storage (ISO DIS/27914)
Figure 7 presents the CCS project lifecycle from the point of risk management responsibility and
oversight to elucidate the risk source and interaction effect. It was developed based on the Global CCS
Institute’s (Figure 2) and Canadian Standard Association’s (CSA) definitions of lifecycle (Figure 5). As
described in Figure 7, the CCS project lifecycle includes all phases of a CCS project from start-up through
operation and closure and into the post-closure period. Figure 7 also includes the components of a CCS
project, the disposition of the CO stream and the risk management responsibility.
2
A CCS project lifecycle includes the subsystems (capture, transportation, and storage) as well as
temporal elements (project design and initiation, operation, closure, and post-closure). Figure 5 was
used in the Canadian Standard’s Association’s “Z741-12 Geological storage of carbon dioxide” (Canadian
Standards Association, 2012) to describe the project lifecycle for a CCS storage project and limitations
to the applicability of the standard.
Figure 7 — Proposed CCS project lifecycle from a risk management viewpoint
For the purposes of this document, the lifecycle of a CCS project is defined as having a start-up
phase which includes opportunity, planning, engineering and construction; an operational phase
which includes capture, transportation and injection; a closure phase; and a post-closure phase. The
“decommissioning” stage referenced in Figures 2 and 4 has been omitted because of differences in
timing and interpretation across various industries and countries.
4.3 Examples of overarching risk assessment processes conducted for CCS projects
While many tools exist to plan, prepare, and execute risk assessment, analysis, and planning, the
following is a brief discussion of the major processes used in the planning and execution (where
applicable) of a number of CCS projects. This list includes the risk assessment tools and approaches
considered or used by the following projects (operators in parentheses): Weyburn (Cenovus), Gorgon
(Chevron), FutureGen 1.0 (FutureGen Alliance), Peterhead (Shell) and White Rose (National Grid
Carbon), In Salah (BP), K12-B (GDF Suez), Lacq-Rousse (Total), Snøhvit (Statoil), Otway (CO2CRC),

PurGen (SCS), Cemex CCS (Cemex), Aquistore (Petroleum Technology Research Centre, or PTRC), and
the Regional Carbon Sequestration Partnerships (RCSP, US DOE).
— Features, Events, and Processes (FEP) database [Quintessa]: This is an online database tool
developed by Quintessa, a scientific and mathematical consulting firm. The database covers
technical, operational, and programmatic risks and is used as a qualitative screening tool for health,
safety, and environment (HSE), causalities, and environmental (water and air) impacts. Expert
input is required both to describe chains of events by which impacts could occur (scenarios) and to
describe and quantify the associated risks. This tool has been employed at the Weyburn (Cenovus)
and In Salah (BP) projects (Quintessa, 2013).
— Performance Assessment (PA) Framework for CO [Quintessa]: In addition to the FEP database,
2
Quintessa has also developed an evidence-based qualitative and quantitative tool which covers
technical, operational, and programmatic FEPs. PA allows for the stakeholder assessment of
decisions and uncertainty of a project. This tool has been employed at the In Salah (BP) and Quest
(Shell) (Quintessa, 2008).
— Risk Assessment Methodology [TNO] The TNO methodology covers technical and programmatic
risks, focusing on human causality, environmental and groundwater risks. Expert input is required
to establish the probability and consequential matrices that can demonstrate long-term safety
performance of the underground storage of CO (TNO, 2016). TNO has also developed Carbon
2
Storage Scenario Identification Framework (CASSIF) (Sijacic et al., 2014) which is a qualitative tool
requiring expert scenario input to identify storage performance and multiple-site screening.
— CO QUALSTORE [DNV]: This product provides guidance on the process and third-party verification
2
for full geologic storage life-cycle risk assessment and analysis as both a qualitative and quantitative
tool, using multiple category inputs (VERITAS, 2010). This tool has been used to actively inform
discussions between project developers and regulators, including Schwarze Pumpe (Vattenfall) and
Quest (Shell). The tool also provided a basis for the DNV-RP-J203 (DET NORSKE VERITAS AS, 2012)
certification which has been used for certification by the CarbonNet project (Victorian Department
of Economic Development, Jobs, Transport and Resources).
