Department of Energy funds milestone North Carolina-led initiative to advance solar energy research

The U.S. Department of Energy will provide $100 million in funding to new artificial photosynthesis research projects, including a $40 million award to the North Carolina-based Center for Hybrid Approaches in Solar Energy to Liquid Fuels, or CHASE, to accelerate fundamental research of the production of fuels from sunlight.

The University of North Carolina at Chapel Hill leads the CHASE partnership, which will work to develop hybrid photoelectrodes for fuel production that combine semiconductors for light absorption with molecular catalysts for conversion and fuel production.

CHASE will blend experiment with theory to understand and establish new design principles for fuels-from-sunlight systems. The CHASE group will receive $40 million over five years to support researchers working to evolve solar energy technology to meet the world’s increasing energy needs.

More than 35 investigators at six institutions — Brookhaven National Laboratory, Emory University, North Carolina State University, the University of Pennsylvania, UNC-Chapel Hill and Yale University — are partners in the CHASE effort.

“We have assembled a very strong team to set brand–new directions in this field,” said Gerald Meyer, director of the CHASE Hub. “Our focus is to use the sun’s energy to directly generate storable liquid fuels.”

In addition to Meyer, Carolina faculty investigators include CHASE Deputy Director Jillian Dempsey; Joanna Atkin, James Cahoon, Jeffrey Dick, Yosuke Kanai, Matthew Lockett, Alexander Miller, and John Papanikolas, of the Department of Chemistry; Rene Lopez, of the Department Physics and Astronomy and applied sciences; Scott Warren of applied sciences and chemistry; and Alexander Tropsha of the Eshelman School of Pharmacy.

The CHASE proposal was developed under the guidance of the UNC Solar Energy Research Center, SERC, founded in 2008 to serve as a regional hub for solar energy research. Its mission is to develop new ways to capture and store the energy of the sun in the high-energy chemical bonds of carbon-based solar fuels. A DOE Energy Frontier Research Center, established at Carolina in 2009, provided foundational research on renewable energy and leveraged North Carolina’s role as a national leader in solar energy production.

“With this support, CHASE will build on a strong foundation of solar energy research here at UNC and establish critical new partnerships that will enable the transformative scientific advances needed to realize liquid solar fuels,” said Jillian Dempsey, deputy director of the CHASE Hub.

A second partnership funded by DOE, the Liquid Sunlight Alliance, headquartered at the California Institute of Technology, will receive $60 million to pursue an approach called “co-design,” which seeks to streamline the complicated steps needed to convert sunlight into fuels to make the process more efficient.

Liquid Sunlight Alliance and CHASE will succeed the Joint Center for Artificial Photosynthesis, the DOE Fuels from Sunlight Energy Innovation Hub, which was established in 2010, and is concluding this year.

The DOE Fuels from Sunlight Energy Innovation Hub program will continue through the combined efforts of Liquid Sunlight Alliance and CHASE. Both are expected to build on the accomplishments of JCAP, as well as several DOE Energy Frontier Research Centers and core research efforts devoted to artificial photosynthesis.

“Sunlight is the world’s most basic energy source, and an ability to generate fuels directly from sunlight has the potential to revolutionize the U.S. energy economy,” said Under Secretary for Science Paul Dabbar in a press release announcing the awards. “This effort will keep America at the forefront of artificial photosynthesis research, a field of great challenge but also huge promise.”

The Department of Energy’s investment in the Fuels from Sunlight Energy Innovation Hub program represents a continuing large-scale commitment of U.S. scientific and technological resources to this highly competitive and promising area of investigation.
