Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climatedamaging carbon dioxide. This book explores how efficiency is measured and reported at coalfired power plants.

IEA Clean Coal Centre Water conservation in coalfired power plants 9 between power plant operators and other water users is likely to escalate, and climate change could further exacerbate the situation. Regulatory restraints by governments may impose limits on, or increase the cost of, fresh water usage by power plants.

It offers a radically different approach to the problem. A conventional coalfired power plant with postcombustion capture has to separate carbon dioxide from a flue gas mixture in which there is a large amount of nitrogen. The oxyfuel process, by removing the nitrogen at the start, so that coal burns in oxygen instead of air, sidesteps this ...

The combined operation of postcombustion CO2 capture and a power plant is a complex process with significant mutual interactions. Although the application of CO2 capture imposes an efficiency penalty on the power plant, it also provides the opportunity to operate the power plant in a more flexible way. To analyze this process, a detailed model of a postcombustion capture plant is developed and ...

Looking at the change in the power sector from 2010 to 2020, there is a reduction in power generation by thermal coal plants. Reports indicate a 30% reduction in power generation from coal fired thermal plants [7, 16, 18]. This is aligned with the reduction of CO 2 released into the atmosphere from coal and gas plants [5, 12].
