Future Power Plants
Not only does Carbon Capture and Sequestration use more COAL - it also uses MORE of our most precious resource - WATER! You will want to click on the link below to read the full article and look at their example of the amount of water used.
"Impacts of Operation on Water:
Capture & Compression: Increased power consumption for capture and compression directly reduces the facility power output -- results in increased water consumption above that for a similar facility without capture
Pipeline Transport: Pumping power required to boost carbon dioxide pressure during pipeline transport to maintain supercritical conditions further diminishes power generation facility output -- results in increased water consumption
Underground Injection: Additional power may be required for injection operations -- indirectly increases water consumption; water may be produced by sequestration operations which displace reservoir fluids"
• Extreme variability exists in water production rates associated with geological sequestration operations
- The viability of potential sequestration locations requires assessment of the geological features of each specific site
• In some cases, water production during sequestration activities can be greater than water consumption during power generation and carbon capture
- Water generated during sequestration is often re-injected into a reservoir to aid continued oil/gas production
- Water produced during sequestration activities may require extensive remediation to make it potable or acceptable for agricultural uses
• Water production/usage during sequestration operations can dramatically effect the economic"
