IEAGHG Risk Management Network – Webinar & Virtual Discussion: The Road to CCS Project Permitting

• 31 March 2022
• Event Proceedings
• Storage

On Tuesday 18th January 2022, the IEAGHG Risk Management Network held a webinar which aimed to be a roundtable presentation of CCS / CCUS (carbon capture and storage / carbon capture, utilisation and storage) project operator experience, with risk management, during the permitting process. This webinar heard from panellists on the Northern Lights project, the Porthos project, California experiences with permitting and Oxy's recent project experiences. The webinar attracted an audience of 138 in addition to 8 panellists and 2 IEAGHG staff.

From Carbon Dioxide to Building Materials - Improving Process Efficiency

• 1 March 2022
• Utilisation

IEAGHG commissioned a study to investigate how captured CO₂ can be used in building materials. It also explored the processes that are used to capture this CO₂ and includes case studies where these processes are happening. The work has evaluated CO₂ utilisation in the context of cement and concrete production by looking into the effects of carbonation on material utilisation and the design of a potential carbonation plant. The market analysis and market pull of carbonated building products is also covered.

Feasibility Study on Achieving Deep Decarbonization in Worldwide Fertilizer Production

• 1 March 2022
• Capture

This study investigated the life-cycle environmental footprint of nitrogen fertiliser production, with and without CO₂ capture, in four different regions: the United Kingdom; Norway; Saudi Arabia; and the United States. The goal was to demonstrate how deep decarbonisation of fertiliser production could be achieved in each of these regions and compare the differences between them. Fertiliser production is an important element in the global food production chain and is key to securing sustenance for the growing global population. This is expected to increase to 10 billion by 20501 and consequently fertiliser production, which currently accounts for about 1.5% of global greenhouse gas emissions2, will continue to be essential.

Global Storage Capacity Workshop 2021

• 18 February 2022
• Event Proceedings
• Storage

The aims of this workshop were to review current methodologies and initiatives for quantifying CO₂ geological storage, review current data availability and assess gaps, establish core international contacts and a community with direct interest in CO₂ storage resource. The workshop also discussed opportunities on how to address the identified data gaps in various parts of the world, through either bilateral or multilateral collaboration and via an international network to collate and refine estimates of CO₂ storage capacity.

Prime Solvent candidates for next generation of PCC plants

• 1 February 2022
• Capture

The primary goal of the study is to review prospective prime solvents and process designs to accelerate the deployment of CO₂ capture technologies. IEAGHG commissioned Khalifa University, United Arab Emirates (UAE) to conduct a comprehensive assessment of promising aqueous and water-lean PCC solvents. This study identifies and characterises prime solvent candidates for the next generation of post-combustion carbon capture (PCC) technology. The solvent comparison was carried out against a benchmark 30 wt.% monoethanolamine (MEA) aqueous solution and the IEAGHG benchmark system (IEAGHG 2019/09)

Criteria for Depleted Reservoirs to be Developed for CO₂ Storage

• 1 January 2022
• Storage

In this review we consider advantages and disadvantages of using depleted fields in comparison to deep saline reservoirs as carbon dioxide (CO₂) storage sites. The study consists of three parts. The first looks at ten case studies with operational experience and the insights they offer. The second presents original research on three factors that may impact evaluation of depleted field storage opportunities: 1) the impact of reservoir pressure depletion on storage capacity prediction; 2) the effect of residual hydrocarbons on capacity and injectivity; and 3) the net economic benefit of inherited hydrocarbon infrastructure, including elements that are reusable and those that are not. The third section is a discussion of criteria for evaluating depleted fields for CO₂ storage.

Current State of Knowledge Regarding the Risk of Induced Seismicity at CO₂ Storage Projects

• 1 January 2022
• Storage

The primary objective of this study is to summarize the levels of induced seismicity observed in or near CO₂ storage sites, and the consequences of the induced seismicity in terms of impact on people, as well as the environment, assets and reputation of operators, authorities, and on CCS technology. A second objective is to gain an understanding on processes that industry and authorities employ to manage the risk of induced seismicity. A third objective is to present notable case studies where outreach measures have supported operators and regulators in managing concerns of stakeholders in connection with induced seismicity. The final task of the study is to identify current research and innovation trends to better manage the risk of induced seismicity.

Assessing the Techno-Economic Performance, Opportunities and Challenges of Mature and Nearly-mature Negative Emissions Technologies (NETs)

• 1 December 2021
• Capture
• Costs of CCUS

The aim of this study is to provide a transparent framework to evaluate the potential (in terms of sequestered and displaced carbon), and economics (in terms of cost of carbon avoided and removed) of a non-exhaustive selection of NETs pathways. Ecosystem and socio-economic impacts associated with their deployment is also quantified. The study sets out to help the carbon capture and storage (CCS) community in trying to gain a better understanding of the costs and value of NETs. It also helps the modelling community in being able to better model the role of NETs; and policy/decision makers in having more information on costs, value and scalability of NETs.

Global Assessment of Direct Air Capture Costs

• 1 December 2021
• Capture
• Costs of CCUS

This study aims to improve the current DACCS cost-performance evidence base by synthesising data from the recent literature and technology developers to explore the economic feasibility of different DACCS technologies (both liquid and solid based systems) across timescales, capacities, configurations, and numerous global siting factors. It also provides recommendations for the integrated assessment modelling (IAM) community and policymakers to inform next steps for DACCS implementation and deployment.

CO₂ as a Feedstock: Comparison of CCU Pathways

• 1 November 2021
• Utilisation

The aim of this study is to present a holistic assessment of the viability (both technically and from a market perspective) of carbon capture and utilisation (CCU) routes and to identify areas of strength and weakness within individual routes, compare different CCU pathways, and identify common drivers, barriers, and enablers. The results of this study will be of interest to the technical community, as well as industry and manufacturers. The study assessed commodities across four different CCU categories (building materials, chemicals, polymers and fuels) regarding their mitigation potential, market uptake potential, technical scalability and other impacts.

CO₂ Utilisation: Hydrogenation Pathways

• 1 November 2021
• Costs of CCUS
• Utilisation

The aim of this study is to assess the feasibility of select carbon capture and utilisation (CCU) routes based upon CO₂ conversion through hydrogenation, in terms of their climate change mitigation potential. The results of this study will be of interest to organisations/individuals involved with climate-change scenario modelling, as well as RD&D financial sponsors. The commodities selected for investigation were methanol, formic acid, and middle distillate hydrocarbons (synthetic fuels: diesel, gasoline, jet fuel), with a focus on catalytic hydrogenation pathways. Results of CO₂ emissions, costs and energy consumption for formic acid, however, will not be presented in detail in this Overview, as the analysis has shown that the abatement is limited to 2 MtCO₂ due to the small market size. (Results for formic acid are available in the full report.)
