Development of a high-performance indirectly hydrogen-cooled turbine generator [News from Japan]

Global warming caused by CO2 emission, and continuously growing power demands world-wide, are of considerable concern. Among the various types of electric power generation systems, thermal power generation is the largest emitter of CO2. Thus reducing the CO2 emission from thermal power generation plants by increasing their efficiency is an important task for the manufacturers of such plants. Thermal power plants and turbine generators are therefore required to supply electric power more efficiently, where efficiency is defined as generator efficiency.
