Artificial Photosynthesis: A Long Standing BES Interest 1st ERDA Solar Photochemistry Research Conference May 12-13 1977 One aspect of this work [in Solar Photochemistry] is the group of studies that have been…called artificial photosynthesis and defined… as the generation of fuel or electricity using model systems which mimic natural photosynthetic systems in light gathering and charge separation.

Energy Innovation Hub – Fuels from Sunlight We are here! For information on DOE Energy Innovation Hubs see: http://www.hubs.energy.gov/ Part of a significant new DOE initiative - one of three Hubs funded at $22M each in the FY 2010 appropriation. Key Dates: • December 22, 2009: Funding Opportunity Announcement (FOA) issued • January 29, 2010: Letters of intent due (but not required) • March 29, 2010: Full applications due • June, 2010: Award announcement • August , 2010: Award initiation The objective of the Fuels from Sunlight Hub is to develop an effective solar energy to chemical fuel conversion system. The system should operate at an overall efficiency and produce fuel of sufficient energy content to enable transition from bench-top discovery to proof-of-concept prototyping. 12
Landscape for Solar Fuels Production: From Basic Research to Market What we can do today: Solar fuels technology currently resides at the basic research level. $12/gal gas equiv Market Applied Solar to Hydrogen Use-Inspired separations Light Absorption, Charge separation & transport dark catalysis Nano- bio photocatalysis 13
Landscape for Solar Fuels Production: From Basic Research to Market The Hub will drive solar fuels R&D toward marketable systems. What we want to do tomorrow: Market • Fuels from Sunlight Hub: • To develop integrated solar fuel systems • To create the scientific and technical infrastructure for a solar fuels industry Applied Use-Inspired • Twofold Integration: • Across components • Across basic & applied R&D 14
Energy Innovation Hubs - Coordination • Three Hubs funded at $22M each in the FY 2010 appropriation: Fuels from Sunlight (SC/BES) Modeling and Simulation for Nuclear Reactors (NE) Energy Regional Innovation Cluster or E-RIC (EERE) – includes the Energy Efficient Buildings Design Hub • Hub Working Group (SC/BES, NE, EERE) coordinates Hub activities and makes recommendations to DOE senior management: • Three separate FOAs from a common template. • Hub cost sharing plan, waiver and reductions per EPAct 2005. • Eligibility allowed for non-DOE FFRDCs (NIST, JPL, etc.) and foreign institutions as partners, not leads. • Developed Hubs website and coordinates updates. • Coordination of Hub merit review process. http://www.hubs.energy.gov/ 15
Energy Innovation Hubs Website Overview of Hub program How to apply, including links to FOAs Description of research areas Q & A – some examples to follow 16
The Other Two Hubs • Modeling and Simulation of Nuclear Reactors (NE): FOA issued January 20, 2010; Full applications due March 8, 2010. The mission focus of the NE Hub is to apply existing modeling and simulation capabilities to create a user environment that allows engineers to create a simulation of a currently operating reactor that will act as a "virtual model" of that reactor. The Hub will also obtain data from that reactor to be used to validate the "virtual model." • Energy Efficient Buildings Design (EERE): Central “hub” of E-RIC, which includes funding from Commerce/Economic Development (up to $5M/yr), Commerce/NIST via supplements to existing MEP awards ($500k/yr), and Small Business Administration ($300k/yr). Dept. of Labor, Dept. of Education, and NSF also commit to supporting collaborations. FOA issued on February 8, 2010; full applications due on May 5, 2010. This pilot initiative will spur regional economic growth while developing innovative energy efficient building technologies, designs, and systems. 17
Energy Innovation Hubs – Q&A • What kind of infrastructure support will be provided for the Hubs? Up to $10M in the first year for start-up, including building leasing or rennovation and equipment, but no new construction. • The Secretary stated that each Hub would be “ideally under one roof." How will this concept influence the Hub selection process? R&D integration is critical for a successful Hub. Key elements for successful management include: A clear lead institution with strong scientific leadership and central location for the Hub. If geographically distributed, a clear commitment to the use of state-of-the-art technology and frequent virtual meetings to enable meaningful long distance collaboration. A clear organization and management plan for achieving the collaborative and synergistic goals of a Hub and “infusing” a culture of empowered central research management. • How will the Hubs be selected, reviewed, and managed? Using procedures now well established in DOE, and particularly SC, for other large FOAs (BRCs, EFRCs, ...). • How will industry participate in Hubs? Closely and in several ways, with the clear understanding that industrial involvement is vital to technology transfer and ultimate commercialization. For more Q&A see: http://www.hubs.energy.gov/ 18
Fuels from Sunlight Hub – Process Update • Letters of Intent (LOIs) were due on Friday, January 29. • LOIs were not required, but were strongly encouraged. • LOIs used only for organizing and expediting the merit review of the full applications. • Details regarding the LOIs (how many?, what institutions?, etc.) are “procurement sensitive” and cannot be made public. • The LOI response was very positive. • We anticipate a lively competition with strong applications – full applications are due on March 29. • As for the EFRC competition, finding unconflicted peer reviewers will be a challenge. • We welcome suggestions or volunteerism from BESAC regarding peer reviewers. We are interested in reviewers with the appropriate technical expertise and those familiar with management of a large, integrated R&D effort. 19
