Renewable Energy Resources Laboratory

 

About RERL 

Renewable Energy Resources Laboratory (RERL) is located at 3107 Engineering Gateway in the UC Irvine. It was established in 2006 with research focuses on fuel cell, new battery, hydrogen storage, advanced heat transfer, and other renewable energy, as well as new materials and nano-structured surfaces for energy application. RERL currently hosts a few state-of-the-art experimental and computational facilities to characterize interface, nano-structure, energy conversion, and heat transfer, and evaluate new material performance and advanced fabrication methods. In past years, the Lab has developed advanced modeling and numerical tools for scientifically based design and controls; new fundamental understanding of reaction interface performance; and advanced heat transfer devices for new energy.
