Many process industries, such as , and pulp and , require large amounts of for such operations as , distillation columns, steam driers and other uses. Typically, for a gas-fired plant the fully installed cost per kW electrical is around £400/kW (US$577), which is comparable with large central power stations. If, to supply thermal energy, the exhaust steam from the turbo-generator must be taken at a.
