7th Post-Combustion Capture Conference Summary

  • 1 April 2024
  • Capture
  • Event Proceedings

The 7th edition of the Post Combustion Capture Conference (PCCC-7) was held on the 25?28 September 2023 and was jointly hosted by the IEAGHG, U.S. Department of Energy (DOE) and the National Energy Technology Laboratory (NETL) and sponsored by Worley, Shell, and Mitsubishi Heavy Industries. (MHI).

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.

  • Event Proceedings

The 9th High Temperature Solid Looping Cycles Network (HTSLCN) Meeting took place from 14th to 15th March 2023 at Palazzo Farnese in Piacenza, Italy, hosted by the CLEANKER consortium. 82 attendees enjoyed a two-day programme with a total of 28 presentations, the official closure of the CLEANKER project with a visit to the pilot plant, a relaxing dinner and a guided tour in the museum of Palazzo Farnese about the millennial history of the city of Piacenza and its territory, from the preRoman age to the XX century.

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.

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.

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.

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.

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.
