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.

Blue Hydrogen: Beyond the Plant Gate

  • 1 August 2022
  • Capture
  • Costs of CCUS

The primary objective of this study is to review the comparative analysis of blue hydrogen production (that is hydrogen derived from fossil fuels and associated CCS) technologies from oil and oil-based feedstocks as well as the supply chain implication. Further, this study includes techno-economic and life cycle assessments of different technology production configurations in regions that have access to oil resources and potential for the deployment of CCS infrastructure at scale.

Low-Carbon Hydrogen from Natural Gas: Global Roadmap

  • 1 August 2022
  • Capture
  • Costs of CCUS

The primary objective of this study is to conduct a techno-economic and environmental assessment of the production of natural gas-based hydrogen with accompanying carbon capture and storage (CCS) technology. Further, the purpose of this study is to enrich knowledge and compare the deployment of steam methane reforming (SMR), electrified SMR (E-SMR), autothermal reforming (ATR), and partial oxidation (POX) with CCS in the Netherlands. The findings of this study will be of interest to policy makers, industrial emitters, as well as technology developers.

Technical Review

Quantifying the Socio-Economic Value of CCS: A Review

  • 3 August 2022
  • Costs of CCUS
  • Public Perception

As policymakers consider options at their disposal to achieve the goals of the Paris Agreement, understanding the socio-economic impacts on local communities and industrial regions is crucial. Integrated assessment models (IAMs) often lack the economic, social and geographic detail to fully reveal the role that CCS and CDR technologies, such as BECCS, can play in national economies – noting that deployment of both CCS and BECCS has long continued to lag expectations. Providing a multi-regional, technology agnostic and transparent quantification of the social value of these technologies may be essential to unlocking this impasse.

7th Cost Network Proceedings

  • 1 November 2023
  • Costs of CCUS
  • Event Proceedings

The 7th edition of the IEAGHG CCS Cost Network Workshop was hosted at the University of Groningen, Netherlands, on 12-13 April 2023. The purpose of the workshop was to share and discuss the most current information on the costs of carbon capture and storage (CCS) in various applications, as well as the outlook for future CCS costs and deployment. For the first time, this workshop also included a session on the direct capture of CO₂ from the atmosphere. The workshop also sought to identify other key issues or topics related to CCS costs that merit further discussion and study.

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.

Techno-Economic Assessment of Small-Scale Carbon Capture for Industrial and Power Systems

  • 1 March 2024
  • 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.

Power CCS: Potential for cost reductions and improvements

  • 5 August 2024
  • Capture
  • Costs of CCUS

CCS, in the context of power CCS technologies, will be an essential component of the portfolio of technologies required to reach net-zero emissions in the power sector. This study explores the potential to reduce the cost and accelerate the uptake of power CCS technologies.
