Publication Overview

The aim of the workshop was to provide members and other stakeholders with an update on the status of CDR, identify crucial knowledge gaps and the mechanisms to resolve them, and find possible cooperation/collaboration opportunities.

Publication Summary

The session on Government and Policy Frameworks had speakers from the US Department of Energy (DOE), the International Panel non Clinmte Change (IPCC) and the Mission Innovation (MI) CDR Mission. Important outcomes were:

  • US makes more than USD 3.5bn for DACCS projects available
  • IPCC emphasises the essential role for CDR, including CCUS, in reaching net zero
  • MI CDR Challenge underway with the production of a Technology Roadmap and an Action Plan.

Keynote talks included a general overview of CDR solutions and more specific presentation on the CDR solutions Direct Air Capturer (DAC), Mineralization and Bioenergy with CCS (BECCS). Key message include:

  • High quality, i.e. permanent, carbon offsets/removal are needed
  • Current DACCS costs tend to be high but significant cost reductions can be realised
  • EM progress is slow, suffering from low TRL, lack of business cases and wider LCAs
  • BECCS work scientifically as a climate mitigation pathway, but the impact will be case and service specific.

After the general introductions to CDR technologies, providers and users of the technologies presented snapshot views. Providers were represented by Mineral Carbonation International (MCi)and Climeworks, whereas the UK power utility Drax and the Norwegian waste-to-energy plant Celsio represented users of CDR. Conclusions are that

  • CDR technology providers are ready to deliver and scale up
  • Users are ready to implement but regulations and accounting systems must be developed.

The workshop included a panel debate on CDR accounting, with participants that have experience from Life Cycle Assessmen (LCA), emissions accounting, both in general and on BECCS and waste-to-energy in particular, as well as from regulatory work. Important outcomes are

  • International cooperation and knowledge sharing is needed
  • Life cycle perspectives are needed, including energy, land and water use and potential trade-offs with sustainable development targets
  • Standards of monitoring, verification and reporting and for Life Cycle and Techno-economic Assessments are needed
  • RD&D is needed to get costs and energy requirements down
  • Nations need CDR strategies.

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.

  • Capture
  • 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.

Defining the Value of Carbon Capture, Utilisation and Storage for a Low-Carbon Future

  • 1 August 2022
  • Capture
  • Utilisation

A key objective of the study was to explore the concept of ‘value’, when applied to a technology deployed in a low-carbon energy system. CCUS is an available mitigation option to support energy transitions and has been highlighted by global IAMs as a necessary technology to limit anthropogenic warming to well below 2°C. Despite this, there continues to be dissent among academics, business leaders and policymakers regarding the role CCUS can or should play in a low-carbon future. This opposition appears to stem not only from a narrow and incomplete focus on cost, and the perception that CCUS is a high-cost mitigation option under all circumstances, but also a failure to recognise the value of CCUS from other perspectives, such as human, social and environmental, to support the energy transition to net zero. As a result, a wider, deeper, and multi-disciplinary review of the ‘value’ of CCUS is explored. Recent literature spanning sector-specific techno-economic models, global and regional IAMs, and social studies to explore the diverse value of CCUS is reviewed. Results from Princeton University’s Net-Zero America study are summarised, where five alternate modelled pathways to net-zero emissions in the United States provided an exceptional level of sectoral, temporal and spatial granularity to highlight the value of CCUS in these pathways. Finally, a semi-quantitative, 2×2 decision framework was introduced to help policymakers screen the relative competitiveness of CCUS as a mitigation option across multiple domains. This framework was applied across a number of case studies, including the United States, the UK, Indonesia, Australia and Japan, to highlight under what circumstances CCUS might prove to be a valuable mitigation option to help these jurisdictions achieve time-bound mitigation goals.

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.

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.

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.

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.
