Publication Overview

This report builds upon previous IEAGHG studies on the topic of carbon capture and utilisation (CCU) in order to assess the potential of a portfolio of CCU technologies to contribute towards Japan’s climate change mitigation goals in 2030 and 2050.

Publication Summary

This report builds upon previous IEAGHG studies on the topic of carbon capture and utilisation (CCU) (IEAGHG 2018a, IEAGHG 2018b, IEAGHG 2018c, IEAGHG 2019), all having been carried out by Carbon Counts. First, an update on recent CCU policy developments is set out. Second, previous research and analysis is assembled into a model – the Greenhouse Gas Emissions Model for CCU (GEMCCU) – to examine the emission reduction potential of CCU on an integrated basis. GEMCCU is used to assess the potential of a portfolio of CCU technologies to contribute towards Japan’s climate change mitigation goals in 2030 and 2050.

The research finds that interest in CCU around the world continues apace, building upon the momentum identified in previous studies. Developments include:

  • OECD countries are increasingly highlighting the important role that CCU could play within their national decarbonisation strategies.
  • The United States, European Union and Japan could provide RD&D funding for CCU in excess of US$700 million over the next 10 years.
  • Evaluations of the climate change mitigation potential of CCU in the literature suggest that CO2 utilisation rates in the order of 100 to 1,100 MtCO2 by 2050 could be achieved under scenarios of comprehensive and sustained climate action.

International Standards and Testing for Novel Carbonaceous Building Materials

  • 1 December 2023
  • Policy & Regulation
  • Utilisation

Over 4 billion tonnes of cement are produced each year, equating to approximately 8% of global anthropogenic CO2 emissions, and this industry will continue to grow with the expansion of the built environment at a time that emissions need to be reduced. The utilisation or reduction of CO2 within cement, concrete and building materials could be a valuable way to contribute to emissions reductions in the sector , but there are several barriers, including the current state of standards, regulations and policies. This study will provide useful information for the technical and research community, the CCUS industry, the construction industry, and policymakers, providing an unbiased and non-prescriptive evaluation of international standards and testing relevant to novel carbonaceous building materials to address some of those barriers. The market potential for CO2 utilisation processes in the construction industry is also investigated, and the methods for certifying and measuring embodied carbon content of carbonated building materials is evaluated and the challenges therein.

Integrating CCS in international cooperation and carbon markets under Article 6 of the Paris Agreement

  • 18 January 2023
  • Policy & Regulation

This work assesses the status of and outlooks for international cooperation under Article 6 of the Paris Agreement and considers how approaches could support the deployment of carbon capture and storage (CCS). It provides an up-to-date look at the Article 6 rules, the types of markets and mechanisms that could evolve, and the units that could be traded. It then considers how Article 6 could apply to CCS through linked emissions trading systems, crediting systems and alternative approaches.

Applying ISO Standards to Geologic Storage and EOR Projects

  • 1 September 2022
  • Policy & Regulation
  • Storage

The work aims to summarise and synthesise the two ISO Standards relevant to the geological storage of CO2: – ISO 27914:2017 (‘Carbon dioxide capture, transportation and geological storage – Geological storage’) and ISO 27916:2019 (‘Carbon dioxide capture, transportation and geological storage – Carbon dioxide storage using enhanced oil recovery (CO2-EOR)’) – to provide a high-level understanding of the content into an easily digestible format. By comparison with international regulatory frameworks, and providing case studies of how applicable the standards are to real CO2 storage projects, the study provides a comprehensive overview and concludes on the usefulness of the documents in supporting the implementation of CCUS projects. For the purposes of this overview, the standards will hereafter be referred to as ISO 27914 and ISO 27916

Exporting CO2 for Offshore Storage – The London Protocol’s Export Amendment and Associated Guidelines and Guidance

  • 12 April 2021
  • Policy & Regulation
  • Storage

The London Convention and London Protocol are the global treaties that protect the marine environment from pollution caused by the dumping of wastes. Since 2006, the London Protocol has provided a basis in international environmental law to allow carbon dioxide (CO2) storage beneath the seabed when it is safe to do so, and to regulate the injection of CO2 into sub-seabed geological formations for permanent isolation. However, Article 6 of the London Protocol prohibits the export of waste or other matter for dumping in the marine environment. Therefore in 2019, Contracting Parties to the London Protocol adopted a resolution to allow provisional application of the 2009 amendment to Article 6 of the Protocol to allow export of CO2 for storage in sub-seabed geological formations in advance of its ratification, which was progressing slowly.

CCS and the Sustainable Development Goals

  • 15 December 2020
  • Policy & Regulation

The overall objective of this assessment was to improve the availability and accessibility of information regarding the relevance of CCS in contributing to the achievement of the Sustainable Development Goals. The primary objective was achieved through the completion of three key goals: <ol> <!– wp:list-item –><!– wp:list-item –><li>Collation of existing information on impacts of CCS on specific targets of the 17 SDGs, using the rating, scoring and information assessment as per IPCC’s SR1.5,</li><!– /wp:list-item –><!– /wp:list-item –> <!– wp:list-item –><!– wp:list-item –><li>Articulation of specific gaps in information, and</li><!– /wp:list-item –><!– /wp:list-item –> </ol> Proposal of a path forward by providing a prioritised lists of gap closures.There is a growing body of literature orientated towards converting climate action into policies directed towards implementation of SDGs. There is also a trend of material becoming available examining the interaction of technologies and sectors against SDGs. CCS remains a complex technological solution to climate change, and public understanding of the technology remains low. This study can help to substantiate the wider value of CCS, but it can also highlight points of attention/action on potentially negative interactions with specific SDGs.

Integrated GHG accounting guidelines for CCUS

  • 1 November 2019
  • Policy & Regulation

This report sets out accounting guidelines for measuring greenhouse gas (GHG) emissions and emissions reduction effects arising from technologies involving carbon dioxide capture, utilisation and geological storage (CCUS).The guidelines apply a project- and product-based approach to measure GHG emission reduction effects, based on comparing the emissions for a CCUS activity with the emissions from a comparable activity delivering the same product or service.A modular approach is applied. Firstly, users calculate the GHG effects arising from the capture (and transport) of CO2 based on the avoided emissions from providing the same service or product as output from the CO2 source facility, but without CO2 capture.The resulting estimate of GHG effects from CO2 capture is carried forward to the utilisation or storage step. In this subsequent step, the GHG emissions from providing the same service without using captured CO2 is estimated and compared to the GHG emissions of providing the service using captured CO2. This provides an overall estimate of the cradle-to-gate GHG effect of CCUS activities.Additional guidance is provided on cradle-to-grave assessment, although this is not the primary focus of these guidelines – the Guidelines focus on annualised GHG emissions accounting cycles rather than whole life emissions analysis.

GHG Accounting for CCU Technologies – Characterising CCU technologies, policy support, regulation and emissions accounting

  • 1 March 2018
  • Policy & Regulation
  • Utilisation

Over recent years, interest in CO2 capture and utilisation (CCU) from policy-makers, industry and academics has increased dramatically, although uncertainty remains regarding the technology’s true potential to contribute towards wider greenhouse gas (GHG) emissions reduction goals. A range of views have been expressed in these contexts, but on the whole it remains largely speculative and unproven. Consequently, it is difficult to provide firm opinions on whether CCU technologies can make a meaningful and lasting contribution to tackling climate change. This report provides an assessment of the range of views presented by various stakeholders, and attempts to establish an empirical evidence base upon which to qualify the views and opinions expressed.Additionally, the key way to gain a clearer understanding of the potential for CCU technologies to reduce GHG emissions is to assess the overall energy and carbon balances for different CCU processes, and to take a view on how and whether these could make a contribution to GHG emission reductions. In other words, as noted by the Intergovernmental Panel on Climate Change (IPCC) in its 2005 Special Report on Carbon Dioxide Capture and Storage (SRCCS) ‘further study of the net energy and CO2 balance of industrial processes that use the captured CO2 could help to establish a more complete picture of the potential of this option’. Such detailed studies have, at best, only partially been carried out and are heavily reliant on the assumptions made in the analysis. Thus, IEAGHG has commissioned Carbon Counts (UK) Ltd to characterise CCU technologies, as well as their policy support, regulation and emissions accounting.

CCS deployment in the context of regional developments

  • 1 August 2017
  • Policy & Regulation

The aim of this study was to characterise key countries and regions worldwide where carbon capture and storage (CCS) could play an important role in mitigation efforts, based on national circumstances and priorities. An additional objective was to identify how international frameworks, such as the UNFCCC, can support CCS and what these new architectures would mean with respect to development of nationally determined contributions (NDCs).

RESERVED CO2EOR Accounting JK

  • 1 October 2016
  • Policy & Regulation
  • Storage

The report attempts to review issues associated with greenhouse gas emissions accounting where anthropogenic carbon dioxide is captured and used for enhanced oil recovery (CO2-EOR) in conjunction with long-term geological storage of CO2. Whilst this suggests a fairly narrow scope of research, it in fact opens up several lines of complex enquiry, requiring a strong understanding of global oil production, trade, supply and demand. This is a topic to which countless hours of debate and consideration are made on an ongoing basis, generally without any clear consensus in respect of matters such as ‘peak oil’, ‘carbon lock-in’ and fossil fuel ‘demand destruction’. It is also a topic that is highly political, with oil being at the heart of economic activity and life-style behaviour. As such, the analysis presented herein has required some simplifying assumptions in order to provide limits to the discussions presented. This has been carried out to the best of the authors’ capacity, commensurate with the time and resources available for the study. The report does not claim to provide a definitive view on how to resolve issues of greenhouse gas emissions accounting for CO2- EOR, but rather provides a source of ideas on how to establish a framework for considering the issues at hand, and food for thought in respect of further discussion and debate.

Review of GHG Accounting Rules for CCS

  • 1 May 2016
  • Policy & Regulation

This report aims to provide a comparative review of how current rules for compiling and reporting inventories of GHG emissions and removals, and for MRV of GHG emissions and removals (hereafter collectively termed “GHG accounting rules”) apply to CCS activities worldwide. These include international, regional and national approaches employed under policies and measures such as mandatory GHG emissions reporting, carbon taxes and emission trading schemes (ETS). The report will identify any significant differences between accounting protocols for CCS, the reasons for differences, and any issues that might arise from their differences. It will identify issues, gaps and potential barriers emerging from the review and possible measures that could be taken to support CCS deployment.

  • Costs of CCUS

This study, undertaken on behalf of IEAGHG by Element Energy (now a part of ERM), explores the role of CCS in decarbonising small-scale industry and power generation applications. While relatively under investigated compared to their larger scale counterparts, reaching net zero will be dependent on successfully addressing the emissions from small-scale facilities. The findings from the study will be of interest to the broader energy community but, in particular, should benefit project developers, the finance community and policymakers.

Clean steel an environmental and technoeconomic outlook of a disruptive technology

  • 1 March 2024
  • Capture
  • Costs of CCUS

This study primarily presents a comparative analysis of steelmaking pathways to cost-effectively decarbonise a steel mill, taking a life-cycle perspective on associated environmental impacts. The roll-out of clean steel technologies is envisioned to have a significant implication for support infrastructure. Therefore, a secondary objective of the study is to gain insights into the primary energy and infrastructure implications associated with large-scale deployment of different steel decarbonisation pathways. Clean steel production will likely be more expensive than steel produced today; this poses additional economic strains on steel producers and consumers. Consequently, a third objective is to estimate the price premium that clean steel could command in existing and future markets. Further, this study formulates recommendations for key stakeholders to support the sector and outlines recommendations for further work.

The Role of Indices in Assessing the Maturity of CCUS Technologies and their Readiness for Deployment

  • 1 February 2024
  • Industry Insights

This study was undertaken on behalf of IEAGHG by Foresight Transitions Ltd. While a technology may be technically mature, it has become increasingly clear that the technology may not necessarily be considered commercially ‘bankable’ by investors. In this study, the potential for an index or indices to provide that confidence was explored. The findings from the study will be of interest to the broader energy community but, in particular, should benefit technology developers, CCUS end users, investors and policymakers.

  • Industry Insights

The driver behind this study is to develop a report built on the on the previous IEAGHG report on methods of leakage mitigation (2007/11). The proposed study should focus on current mitigation and remediation methods that may be applied or considered in site specific conditions in the event of unpredicted CO2 migration. Each geological storage site will have an adaptive site specific monitoring plan, based on a risk assessment. Detection of a significant irregularity may involve supplementing the monitoring program, in order to detect a possible leak and if necessary engaging mitigation measures.

Components of CCS Infrastructure – Interim CO2 Holding Options

  • 27 November 2023
  • Storage
  • Transport

This work, undertaken on behalf of IEAGHG by TNO and SINTEF, provides an overview of temporary / interim CO2 storage, or ‘holding’, options (also called buffers) and investigates the role of buffer storage and its potential to create flexible and robust carbon capture and storage (CCS) chains. The report looks at current and emerging buffer technologies, conducts simulations to demonstrate the temporary storage required for given flow-rate scenarios and discusses the impact of buffer capacity on transport costs. In the report, the storage requested in the chain for normal operation is presented as " temporary storage" and storage to give buffer capacity is presented as " buffer storage". This report has focussed on buffering at the emitter site. The results of this study will benefit CO2 storage site project developers, operators, financiers and regulators.

Classification of Total Storage Resources and Storage Coefficients

  • 1 November 2023
  • Storage

The CO2 Storage Resources Management System (SRMS) is a classification scheme to quantify, classify and categorise CO2 storage resources. It comprises ‘total storage resources’, which are understood as maximum (theoretical) storage quantities that could ever be accommodated in the subsurface. Comprising maximum mobile CO2 in structural/stratigraphic traps, maximum residually trapped CO2 in other parts of the formation, and maximum dissolution potential in remaining formation water. ‘Storable quantities’ are understood as accessible from one or several current or future projects. It is the sum of capacity, contingent and prospective resources. The concept of ‘storage coefficient’ ‘E’ is the ratio of the subsurface volume of CO2 storable quantities to either the total storage resources or the pore volume. The calculation is arguably complicated as E is impacted by lithological heterogeneity, trapping structures, boundary conditions, injection rates, well spacing, fluid properties etc. Due to its complexity, there is much controversy on how to estimate E, with some arguing it should not be used at all and that reservoir simulation is a better path. However, estimates for E are used in most regional mapping studies. This study explores storage resource classification schemes and their evolution in understanding, the calculation of storage resources and the storage co-efficient. This is explored in terms of calculating E for CO2 storage sites, through flow modelling and analytical solutions.
