A 1000 MW dry cooled coalfired power station would typically require around GL of water per year. While dry cooling reduces water consumption to around 2 GL/year (from around 17 GL/year), it also reduces sentout efficiency, which leads to higher fuel requirements and higher emissions of carbon dioxide and other greenhouse gases. ...

In the western US, wetrecirculating systems are predominant. Drycooling systems use air instead of water to cool the steam exiting a turbine. Drycooled systems use no water and can decrease total power plant water consumption by more than 90 percent. [2] The tradeoffs to these water savings are higher costs and lower efficiencies.

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...
