Publication Overview

The purpose of this study is to review the technical options that may be available to retrofit a capture technology to the various configurations of power plants that may be built in coming years and to identify (a) necessary and (b) potentially economically attractive options for pre-investment in those plants to make retrofit economically feasible.

Publication Summary

A study of options for CO₂ capture retrofit and potential pre-investments should be carried out as part of the process of qualifying a new power plant as “capture ready”.

The key issues for capture ready plants are inclusion of sufficient space and access for the additional facilities that would be required and identification of reasonable route(s) to storage of CO₂. Pre-investment in these essential capture ready features is in general expected to be relatively inexpensive.

Optional further pre-investments could be made to reduce the cost and downtime for CO₂ capture retrofit. Some relatively minor pre-investments could significantly improve the ease of capture retrofit.

Opportunities for substantial economically attractive pre-investments are expected to be limited, unless capture is going to be retrofitted relatively soon after start-up of the power plant. This is mainly because of the effects of economic discounting and uncertainties regarding future technological developments, regulatory requirements and prices of carbon credits.

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.

Start-up and Shutdown Protocol for Natural Gas-fired Power Stations with CO₂ Capture

  • 1 August 2022
  • Capture

In modern power grids, a power plant with CO₂ capture will be required to operate as a low-carbon, flexible, dispatchable power generator. A recent IEAGHG study showed it is possible to achieve net-zero CO₂ emissions from coal-fired and gas-fired power generation by employing higher capture rates and, in the case of coal-fired generation, by employing a mix of capture rates and biomass.

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.

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.

  • 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.
