The Resnick Sustainability Institute supports research in energy science and technology, and promotes education and communication. The Resnick Sustainability Institute runs a competitive fellowship program which supports a number of graduate students and postdoctoral scholars working on making fuels from sunlight at Caltech. The Resnick Sustainability Institute also supports researchers studying photovoltaic solar cells, energy efficiency, energy distribution, and biochemical processes to reduce that carbon footprint of industry.
The Center for Solar Fuels at the University of North Carolina (UNC) is an Energy Frontier Research Center (EFRC) supported by the U. S. Department of Energy. The UNC EFRC targets basic science to enable the collection and conversion of energy from sunlight into solar fuels. The UNC EFRC is focused on solar fuels technologies based on dye-sensitized semiconductors and on making carbon-containing fuels from carbon dioxide, water, and sunlight. The UNC EFRC is led by Professor Tom Meyer, and includes partners at the University of Florida, the Georgia Institute of Technology, the University of Colorado at Boulder, and Brookhaven National Laboratory.
ANSER was launched in 2007, and is a joint research effort between Northwestern University, Argonne National Laboratory, the University of Chicago, and Yale University. In 2009, ANSER became one of the original Energy Frontier Research Centers (EFRCs) supported by the U. S. Department of Energy. ANSER targets the basic science behind molecules, materials, and methods needed to create dramatically more efficient technologies for the production of solar fuels and solar electricity. ANSER includes research on inorganic semiconductors (such as silicon) as well as organic semiconductors (such as plastics). ANSER targets both hydrogen and carbon-containing solar fuels.
SOFI is led by Northwestern University. The mission of SOFI is to support the development of efficient and cost-competitive systems that make liquid fuels from sunlight. SOFI promotes collaboration amongst global researchers working to make fuels from sunlight. SOFI provides collaborative tools and opportunities in exchange for paid memberships.
The Solar Energy Research Center (SERC) at Lawrence Berkeley National Laboratory is working to develop abiotic systems which make fuels from sunlight. SERC emphasizes nanoscale photovoltaic cells to collect sunlight, with a major project aimed at using nanoscale photovoltaic cells as building blocks for large-scale photovoltaic arrays. SERC develops light-absorbing molecules for hybrid photovoltaic elements (similar to dye-sensitized solar cells) and also develops molecular catalysts that make fuels from carbon dioxide, water, and electricity.
Center for Bio-Inspired Solar Fuel Production (BISfuel)
BISfuel is an Energy Frontier Research Center that was established in 2009 by the U. S. Department of Energy. BISfuel is housed within the Arizona State University Center for Bioenergy and Photosynthesis. The mission of BISfuel is to adapt fundamental principles behind natural photosynthesis to construct a complete man-made system for making fuels, such as hydrogen, from sunlight.
RTSFI is a partnership between Duke University, North Carolina State University, RTI International, and the University of North Carolina at Chapel Hill. The goals of RTSFI are to accelerate the science behind making fuels from sunlight to provide a commercial supply of liquid fuels and to stimulate economic investment in solar fuels technologies. RTSFI seeks to produce hydrogen from water and sunlight. Research focuses on semiconductors, dye-sensitized solar cells, nanomaterials, and integration of components.
Led by Professor Gary Brudvig at Yale University, the Energy Sciences Institute aims to develop new materials for energy production and storage, including the design, synthesis, optimization, and integration of components for a device that makes fuels from sunlight. The Energy Sciences Institute hosts faculty across the physical sciences. For example, The Brudvig Group focuses on dye-sensitized solar cells, specifically on developing dyes which mimic natural photosynthesis by absorbing light and transferring energy from the dye molecules to metal oxide semiconductors. Professor Shu Hu, a Lewis Group alumnus, is a member of the Energy Sciences Institute, and the Hu Group focuses its research on photocatalysis and the electrochemistry of semiconductors.
KCAP was launched in 2009 at Sogang University. KCAP seeks to further the basic science and to develop original technologies to enable fuels to be made from sunlight commercially.

KCAP partners with the Helios Solar Energy Research Center at Lawrence Berkeley National Laboratory, with the Joint Center for Artificial Photosynthesis, and with the Solar Fuels Institute.
Swedish Consortium for Artificial Photosynthesis
The Swedish Consortium for Artificial Photosynthesis (SCAP) was founded in 1993. SCAP is conducting basic research into the production of hydrogen fuel from water and sunlight. SCAP researches both abiotic and biological approaches to making fuels from sunlight. SCAP researchers design and synthesize complex molecular catalysts, and also genetic and metabolic principles of molecular biology and synthetic biology.
ARPChem is a consortium of Japanese universities and companies established in 2012 to produce hydrogen fuel from water and sunlight using photocatalysts. ARPChem includes photocatalysts which simultaneously produce fuels and oxidants in close proximity in their research portfolio, and thus also has a focus on separating chemical products from solution. This aspect of the work being done by ARPChem distinguishes their portfolio from that of the Lewis Group and others which focus exclusively on electrochemical cells where fuels and oxidants form in distinct and separated compartments.
Since plastics and many other chemicals are currently derived from fossil fuels, ARPChem also seeks to develops catalysts that produce basic chemical substances, such as the raw materials needed for plastics, from carbon dioxide, water, and sunlight.
LPI at EPFL is a Swiss effort led by Professor Michael Graetzel. The solar fuels group at LPI aims to develop materials and processes for generating hydrogen or carbon-containing fuels from carbon dioxide, water, and sunlight. This group focuses on inorganic systems. The Graetzel group studies semiconductors, particularly metal oxide semiconductors, and coupling catalysts to semiconductors in devices. Historically the Graetzel group has been a powerhouse in the field of dye-sensitized solar cells, and the group is now a leader in developing perovskite solar cells. The Graetzel group includes solar fuels devices consisting of separate solar cells wired to electrolyzers in their portfolio.
