The cost reduction potential for CCUS at coal-fired power plants, November 2019  

Authors: International CCS Knowledge Centre & Coal Industry Advisory Board (CIAB) 

The 2015 United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement limits the increase in global average temperature rise to well below 2°C above pre-industrial levels. To meet this target, large-scale, emissions-intensive, industrial and power generation processes must be significantly decarbonized. Reductions of this magnitude cannot be achieved without accelerated progress in the commercial-scale deployment of carbon capture, utilization and storage (CCUS) across a wide variety of applications. Authored by the International CCS Knowledge Centre in conjunction with and the Coal Industry Advisory Board (CIAB) -  an associated board to the International Energy Agency (IEA) - this report documents encouraging improvements and learnings from first-mover projects that result in cost savings strategies for subsequent CCUS projects.

Post-combustion CO2 capture processes require thermal energy (from steam) for amine regeneration. In coalfired power stations, steam can be extracted from within the steam cycle – resulting in a power production penalty. Heat integration is the study of minimizing energy consumption while maximizing heat recovery; required for successful CCS retrofits. In October 2014, the world’s first fully integrated carbon capture facility, SaskPower’s Boundary Dam Unit 3 (BD3), went on line. Various modifications to the turbine and feed heating system at BD3 contributed greatly to overall project costs. Novel heat integration strategies can reduce these costs. SaskPower’s Shand Power Station (Shand) is a 305 MW, single unit, subcritical, lignite coal-fired power plant producing approximately 1100 kg of CO2/MWh. Shand’s capacity is twice that of BD3’s - an ideal candidate for a CCS scale-up project. Using the design of the BD3 facility as a basis, heat integration analysis of the existing steam cycle at Shand was conducted using GateCycle™ with aims to minimize costly modifications to the feed heating system.

The integration of CCS to a coal-fired power plant not only results in the increase in water consumption and cooling duty, but also additional water discharge especially from cooling the flue gas to the much lower temperature required for the CO2 capture process. This paper presents the design of a heat rejection system for the Shand Power Station that maintains a neutral liquid impact on the existing plant while adding SO2 and CO2 capture processes. Moreover, the effect of temperatures throughout the year on heat rejection load and power consumption is investigated.

The International CCS Knowledge Centre experts spearheaded a feasibility study to retrofit SaskPower’s Shand Power Station, (Shand) a 300 – MW, single unit, coal-fired power plant that has double the capacity of Boundary Dam 3 CCS Facility (BD3) with a large-scale, CCS facility.

On October 2, 2014, the first-ever, commercial-scale, coal-fired power plant incorporating amine solvent absorption carbon capture began operation near Estevan, Saskatchewan, Canada. This was a global landmark event. Although carbon capture technologies had been pilot tested prior to this, a commercial-scale power plant now exists that has demonstrated that a number of high-risk technology and business issues have been overcome. This report summarizes e experience and learnings of SaskPower in a way that will hopefully provide insight to other clean-coal initiatives.
