Water use in thermal power plants equipped with CO2 capture systems
28th September 2016
Topic(s): CO2 capture
Addition of a CO2 capture system to an existing power station has some impact on water consumption. CO2 capture systems require additional water for cooling and process make-up, which can be of concern, particularly in areas of water scarcity. During the past decade, a number of relevant studies have been published that estimate the increase in water use when a capture system is added to Pulverised Coal (PC), Natural Gas Combined Cycle (NGCC) and Integrated Gasifier Combined Cycle (IGCC) power production facility.
The report, authored by the Institute’s capture experts Guido Magneschi, Ron Munson and Tony Zhang, provides insights about how adding a CO2 capture system to a power plant impacts the volume of water withdrawn and consumed. The results of this analysis serve to dispel myths about the use of water in CCS systems. Specifically, they challenge the misleading assertion that CCS systems will double water consumption, which is often reported in papers and articles.
On the contrary, analyses of available data indicate that for power plants using wet-recirculating cooling systems, the increase in actual water consumed varies from approximately 20 per cent to 60 per cent, depending on the capture technology. For once-through cooling systems the increase can be negligible, or even negative when water recovery options are implemented. Water use estimates cannot be generalised, and are very dependent on the power plant type, the CO2 capture technology and the cooling system used.
The Global CCS Institute is pleased to announce the release of our Global Status of CCS: 2014 report.
The report provides a detailed overview of the current status of large-scale CCS projects worldwide, finding that 2014 has been a pivotal year for CCS, which is now a reality in the power industry.
For the first time, the report introduces and provides links to project descriptions for around 40 lesser scale ‘notable’ CCS projects. The 2014 report focuses on a number of ‘notable’ projects in Japan.
The Global Status of CCS: 2014 report provides a comprehensive overview of global and regional developments in CCS and what is required to support global climate mitigation efforts. Providing a number of key recommendations for decision makers, The Global Status of CCS: 2014 report is an important reference guide for industry, government, research bodies and the broader community.
The Global Status of CCS: 2014 Summary Report provides an executive overview of the key findings and recommendations contained in the Institute’s Global Status of CCS: 2014 report.
The Supplementary Information presentation package includes chart materials not included in the Global Status of CCS: 2014 report. This material provides additional detail on the status of large-scale CCS projects globally. When used in conjunction with previous status reports, it provides researchers with access to the world’s most comprehensive historical data set on large-scale CCS projects.
Tenaska share their analysis of the commercial market factors which drive their project. This project plans to sell electricity into the Electricity Reliability Council of Texas (ERCOT) energy market, capture over five million tonnes of CO2 per year, and sell it into the Permian Basin Enhanced Oil Recovery (EOR) market both of which have large unmet demand. This report discusses the economic realities facing the Trailblazer Project to incorporate a commercial-scale carbon dioxide capture plant into its initial design. It reviews the markets for both electricity and carbon dioxide, and discusses the governmental support that may be needed to bridge the gap between the Project’s likely costs and revenues.
