讲座题目:Linear Fresnel – a Concentrating Solar Power Technology to Advance Energy Innovation


 Linear Fresnel is one of two line-focus concentrating solar power technologies. It utilizes an array of flat or near-flat mirrors to track the sun and concentrate sun light to a fixed receiver assembly. The mirrors are aligned in rows close to the ground and the receiver assembly includes one or multiple absorber tubes with an optional secondary reflector.

 The generated high-grade heat from linear Fresnel collectors can be used in various types of applications: 1) electricity generation through a thermodynamic cycle; 2) combined heating & cooling system at a commercial scale; 3) green fuel generation through bioenergy/solar hybrid systems; 4) water desalination. In addition, the talk will discuss the latest progresses in the development of an innovative linear Fresnel collector with an industrial partner. The new design adopts water-borne mini-size tube reflectors and has a great potential to reduce the current-level collector cost by half.


 Dr. Guangdong Zhu has been a senior research engineer in the concentrating solar power (CSP) program and the Geothermal Technology (GT) program of the Buildings & Thermal Systems center at the National Renewable Energy Laboratory (NREL) since 2010. At NREL, he is leading research efforts related to solar collector optical characterization, linear Fresnel technology, and techno-economic analysis of solar hybridization with other types of energy systems. He won NREL’s President’s award and Outstanding New Partnership Award in 2016. Prior to joining NREL, Dr. Zhu worked in industry and had worked on optimization, prototyping and engineering of advanced molten salt concentrating solar systems. Dr. Zhu obtained his Ph.D. from the University of New Mexico, M.S. from Xi’an Jiaotong University and B.S. from Northeast China Institute of Electric Power Engineering .
