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.
Heat integration analysis and optimization for post combustion CO2 capture retrofit study of SaskPower’s Shand Power Station, May 2019
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.
