Abstract

ALSTOM Power R&D laboratories run various programs aimed at finding options that reduce or avoid CO2 emissions through the following: (a) high efficiency power generation equipment to utilize fossil fuels with the lowest possible emissions, and (b) technologies to remove and sequester CO2 created in power plants in an environmentally and economically favorable manner. In this paper, an overview of ongoing CO2 mitigation activities for gas turbine power generation is addressed. Energy efficiency improvements for both new and existing fossil fuel power plants are briefly reviewed. Customer requirements for future power plants with reduced CO2 emissions are discussed. Novel power generation cycles with exhaust gas recirculation for enhanced CO2 removal are introduced and evaluated. Conclusions are drawn regarding their efficiency, energy consumption, and technical feasibility.
