Introduction. Integrated Gasification Combined Cycle (IGCC) technology can reach a higher efficiency rate than typical coal combustion technologies, such as sub-, super- and even ultra-supercritical combustion. Where the latter can reach efficiencies of between 30 to 45%, IGCC plants could achieve an efficiency rate of higher than 45%.
Natural gas power plants can achieve over 60% efficiency in simple cycle mode and around 65% in combined cycle configuration. Why are renewable energy power plants gaining popularity? They produce clean and eco-friendly electricity from abundant natural sources, making them sustainable long-term options to mitigate climate change.

Historically successful combined cycles have used mercury vapour turbines, magnetohydrodynamic generators and molten carbonate fuel cells, with steam plants for the low temperature "bottoming" cycle. Very low temperature bottoming cycles have been too costly due to the very large sizes of equipment needed to handle the large mass flows and small temperature differences. However, in cold climates it is common to sell hot power plant water for hot water a
