摘要

The global power generation scene is a contest between goals that are often contradictory: Ensuring a reliable power supply, reducing emissions, and cutting costs. Developing power generation technologies for the future involves reconciling these contradictions. Yet, two-thirds of the worldwide demand for power that is expected to double by 2020, will continue to be met by fossil fuels despite their increasing prices (Figure 1). Global coal fleet capacity is expected to increase 50% while nature gas-fired generation will increase by 60% by 2020. Therefore, thermody-namic processes known today to burn these fuels will be the focus of evolutionary developments in technology, materials and manufacturing, unless major breakthroughs in technology and the competitive position of fuel cells or nuclear fusion are made. It is on this complex playing field of rapidly changing market demands that the manufacturers of components, systems and services for power generation have to operate. It is evident even today that, going forward, a much wider portfolio of technologies and processes will have to be available, if providers are to be able to offer the best solution to each challenge. The power industry is expected to reduce and possibly eliminate carbon emissions in the future. Technology is available today to reduce CO{sub}2 emissions, but the process needs more years of development before it can become commercially viable in power plants.
