Worldwide, coal is the most abundant of the recoverable fossil fuels and its reserves are also the most widely distributed. The total recoverable reserves of coal are estimated at 1083 billion tonnes; enough to last approximately 210 years at current consumption levels. As current projections indicate continuing growth in world energy use, the owners of energy, refining and petrochemical facilities are looking for feasible and sustainable technology solutions for the clean production of electricity, chemicals and fuels.
High oil and gas prices have lead to a resurgence of coal as an affordable energy source. Especially coal-rich regions have increasingly been tapping their local resources. This allows them to reduce their reliance on foreign imports of natural resources and at the same time achieving stable prices to meet ever growing energy demands. Gasification offers one of the cleanest and most flexible ways of converting coal and low-grade fuels into high-value products – electricity, chemicals or synthetic fuels. Combining gasification with advanced gas turbines in Integrated Gasification Combined Cycle (IGCC) power plants results in a highly efficient technology for coal-based power generation. Environmental requirements are becoming more and more stringent all over the world. Gasification projects are attractive solutions as they can offer environmentally friendly plants with lower emissions and the combination with readily available technology for CO2 Capture and Storage (CCS). Coal gasification polygeneration is said to be the effective solution to develop advanced coal chemical and green power industry. As it could reduce pollutant and CO2 emission, realize the recycle use of materials, produce chemicals and generate electricity in the whole process.
