2015

University of Minnesota Solar Energy Laboratory demonstrated continuous fuel production from a 4 kW prototype solar thermochemical reactor operated in Minnesota's indoor solar simulator over 140 hours. The reactor is the first to produce fuel continuously on-sun and to recover over 90% of the sensible heat of the working gases. For CO2 splitting, the average solar to fuel efficiency was 1.64% (without consideration of the energy costs of producing nitrogen). The reactor technology developed with support from ARPA-E and the University of Minnesota represents a significant engineering success in the design, construction, and operation of a durable reactor capable of continuous fuel production. The reactor design is also well suited for other isothermal solar processes that promise higher efficiencies.

Dr. Rohini Bala Chandran received her PhD degree for developing models of heat and mass transport and chemical kinetics in solar thermochemical reactors. Dr. Bala Chandran has accepted a Postdoctoral Researcher position at Dr. Adam Z. Weber's Energy Storage Group in Lawrence Berkeley National Laboratory where she will use physics-based modeling to design a low cost photoelectrochemical reactor for water splitting.

Graduate students Peter Krenzke and Stephen Sedler were finalists in the 2015 Dow Sustainability Innovation Student Challenge Award (SISCA) for their work on development of a solar reactor to split water and carbon dioxide.

Professor Jane Davidson was an invited keynote speaker at the 23rd National Heat and Mass Transfer Conference of the Indian Society for Heat and Mass Transfer held in Trivandrum in December 2015. She presented a paper which summarized advances in modeling of solar thermochemical reactors and operation of reactors developed at the University of Minnesota.

Doctoral student Jesse Fosheim has been awarded the prestigious Graduate Research Fellowship from the National Science Foundation (NSF).

Solar Energy Laboratory demonstrates continuous on-sun production of SUNgas for 36 hours straight in their solar simulator. The reactor operates at 1500 Celsius and includes a novel ceramic heat exchanger to recuperate 90% of the sensible heat of the reactant and
product gases. The reactor technology was showcased at the 2015 ARPA-E summit.
