EPRI Research - Coal-Fired Power with Solar

While environmental groups argue merits of various green energy alternatives, EPRI plans for solar steam to reduce coal consumption.

As renewable energy technologies become more commonplace, more questions emerge as to the practicality and other problematic side-effects from otherwise promising approaches. Even solar technologies have come into question with problems related to disposing of spent photovoltaic panels.

The Electric Power Research Institute (EPRI) assists the electric utility industry by researching new technologies related to the generation, delivery, and use of electric power. Its member utilities are responsible for more than 90% of the electricity generated in the U.S., with international participation from 40 countries. The group has researched many environmental and renewable projects, guiding development from concept through evaluation, texting, and commercialization.

As one of its renewable energy projects, EPRI is in the evaluation phase with two new projects to study solar steam generation that can supplement conventional thermal technologies, allowing utilities to increase output or reduce fossil fuel consumption. The objectives of the studies are to determine the practicality and effectiveness of adding solar steam generation to existing natural gas combined cycle plants and conventional coal-fired plants.
