Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

The Third Assessment Report of the Intergovernmental Panel on Climate Change estimated that the near-term cost of reducing carbon emissions would decline with global trading. This decline was based on the assumption that costs of reducing carbon emissions are lower in developing countries than elsewhere. In this paper, we test this hypothesis by estimating the cost of reducing emissions through the use of combined cycle units in place of coal power plants in India. Using data from power plants proposed by independent power producers, we estimate the cost of carbon reduction to be $144/tC. Capital, fuel and other costs are all higher for combined cycles units in India than in the US, while they are comparable for the technologically mature coal plants in the two countries. As the combined cycle technology matures, the cost differential may narrow in the future to as low as $6/tC. A key conclusion of this study is that to the extent project-based activities, e.g., under CDM, rely on new technologies to reduce carbon emissions from similar sources, the cost of carbon reduction may be higher in developing countries, since new technology costs in a nascent market are often higher in these countries.
