Chattanooga, Tenn., June 28, 2010 — Officials and representatives in Chattanooga, Tennessee, today inaugurated the Bloom Box, a 100 kW energy server based on cutting-edge fuel cell technology from California’s Bloom Energy.

The project is the continuation of a long-standing partnership, facilitated by Congressman Zach Wamp, between the University of Tennessee at Chattanooga, the National Center for Computational Engineering (SimCenter), EPB, TVA, The Enterprise Center and Bloom Energy that began with Bloom’s first field trial of its technology in 2006. That successful field trial was a key milestone on Bloom’s path to commercialization.

“UTC and the Tennessee Valley, have been exceptional partners from the beginning and the valuable insights gained here have helped shape our product into the commercially viable entity it is today,” said KR Sridhar, Co-founder and CEO of Bloom Energy. “We are thrilled to be here to celebrate the continuation of Bloom Energy’s collaboration with Tennessee’s Congressional leadership, the Tennessee Valley Authority, EPB, and the University.”

With major support from Congressman Zach Wamp, and in conjunction with TVA, this project will provide 24/7 clean reliable power to EPB’s building.

“The Tennessee Valley has been involved with this technology for a long time, and we’re now at the point of demonstrating its viability as a compliment to the grid. The ultimate goal would be to manufacture fuel cells in Tennessee and further advance the new manufacturing boon in the Tennessee Valley Corridor,” said Congressman Wamp. “Bloom’s technology could have a tremendous impact for the world in creating new energy sources and is cleaner and more efficient than much of today’s power generation. Fuel cell technology coupled with increased nuclear energy could significantly shrink our country’s carbon footprint.”

Located on the top floor of the EPB building’s parking garage, in downtown Chattanooga, the Bloom Box will be a showcase piece for innovation and for successful collaboration between the public and private sectors. By working closely with TVA, this project also highlights how distributed generation technologies such as Bloom’s can be an integral part of a clean smart grid for the 21st century.

“Energy independence and preserving the environment are critical national priorities. An efficient economical fuel cell with low or negligible carbon emission that can operate on a wide range of locally available fuels-such as natural gas and other biofuels — and then provide distributed electrical power without major transmission loss is one element in the solution to this critical issue,” said Dr. Harry McDonald, holder of the Chair of Excellence in Computational Engineering at the National Center for Computational Engineering (SimCenter). “This type of research is exactly why the SimCenter must continue to grow and widen its interests to provide Chattanooga, the state and the nation with well-educated engineers to solve challenging important problems.”

The units will be closely monitored by EPB, Bloom Energy, and the National Center for Computational Engineering (SimCenter) to optimize and simulate performance and to provide educational value on cutting edge energy technology.

Chattanooga continues to be on the forefront of technology. Home to the National Center for Computational Engineering (SimCenter), the largest municipal 100 percent Fiber Optics network, and one of the most automated Smart Grids in the nation, the 100 kW Energy Server is yet another shining example of Chattanooga quickly becoming a recognized national leader in state-of-the-art thinking and innovation.
