The National Energy Technology Laboratory, on behalf of the U.S. Department of Energy (DOE), is pleased to announce its selections for solid-state lighting (SSL) funding opportunities. Fourteen projects were chosen in response to Core Technology and Product Development Funding Opportunity Announcements (Round 5). These selections are anticipated to significantly contribute to the goal of the SSL program:
By 2025, develop advanced solid-state lighting technologies that, compared to conventional lighting technologies, are much more energy efficient, longer lasting, and cost competitive by targeting a product system efficiency of 50 percent with lighting that accurately reproduces sunlight spectrum.
Seven selections have been made in response to Core Technology Funding Opportunity Announcement (FOA) DE-PS26-08NT00290. These selections are expected to fill key technology gaps, provide enabling knowledge or data, and represent a significant advancement in the SSL technology base. The total value of selections for Core Technology Research is $10.4 million; the performers of cooperative agreements will provide an average of 24 percent as cost-share.
Seven selections have been made in response to Product Development FOA DE-PS26-08NT00291. These selections are focused on the development or improvement of commercially viable materials, devices, or systems. Technical activities are focused on a targeted market application with fully defined price, efficacy, and other performance parameters necessary for success of the proposed product. The total value of Product Development selections is $15.6 million; the performers will provide an average of 27 percent as cost-share.
All 14 new selections are covered under the Exceptional Circumstances Determination (PDF 5 KB) issued by DOE in June 2004. The selections are listed below (subject to negotiation).
