Publication Overview

This study assess the technical challenges associated with full-scale design and operation of conventional post-combustion capture technologies for supercritical pulverized coal (SCPC) and natural gas fired combined cycle (NGCC) power plant. In this study technical and operational risks, performance gaps, technical challenges and sensitivity to several process variables are evaluated. Finally, a suggested scale-up strategy was developed with a focus on specific areas for development in future.

Publication Summary

Several areas where engineering and equipment development is required have been identified in this study. This study has mainly concentrated on the designs of the major equipment required for the CO₂ capture system. A major challenge for designing a system, especially when considering the eventual disposal of the captured CO₂, would be the design of the instrumentation and controls for this system. Although scale up of CO₂ capture process is possible without significant development, cost and performance, still these areas could be improved further by additional R&D. The IEAGHG programme should encourage equipment developers and suppliers to address issues identified in this study. This could be best done by improved interaction of different parties working in the engineering community. IEAGHG is not in a position to undertake the necessary development but could provide some guidance to those who are.

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.

Clean steel an environmental and technoeconomic outlook of a disruptive technology

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.
