We are aware of the present scientific concerns regarding greenhouse gas emissions and the role of fossil fuel use for power generation. Although the scientific and policy dialogue on global climate change is far from conclusive, we want to design high efficiency power generation equipment with the most modern technologies to utilize fossil fuels with the lowest possible emissions and technologies to remove and sequester carbon dioxide created in power plants in an environmentally and economically favorable manner. This paper is an overview of activities to study and develop controls for carbon dioxide (CO2) emissions from power generation. First, energy efficiency improvements for both new and Existing fossil fuel power plants are briefly reviewed for both coal and natural gas fuels. Greater depth is then given to options for CO2 capture and sequestration. These studies are looking at current and novel power generation technologies.
