PhosphorTech Corp. of Lithia Springs, Ga., has brought to the market new materials and structures, which can be used in the next generation of light-emitting diodes, or LEDs. The new phosphor-based materials are more efficient at creating light and enhance the performance of traditional LEDs. PhosphorTech's research has been funded in part through an NSF Small Business Innovation Research (SBIR) grant and was recently honored with the Department of Energy's award for significant achievements in solid-state lighting R&D.

Another energy efficiency advance has been made by Sustainable Innovations of Glastonbury, Conn. In partnership with Harvard University, this small business has created a novel energy storage system using a hydrogen/chlorine electrochemical cell. Through the use of a high efficiency energy storage system, renewable energy sources, such as solar energy, can be used to provide power at all times, not just when the sun is shining. Sustainable Innovations' research is funded in part through NSF's SBIR program and is helping to support several university students.
