higher temperatures and higher effi- ciency power cycles that will bring down the cost of electricity produced from concentrating solar power,” Ho said. “In addition, the ability to cheaply and efficiently store thermal energy directly in the heated parti- cles will enable power production at night and on cloudy days.” Falling particle receiver tech-
nology is expected to further advance the state-of-the art in concentrating solar power tower systems capable of generating up to 100 megawatts of electricity. Sandia’s partners in the Depart-
ment of Energy project are the Geor- gia Institute of Technology, Bucknell University, King Saud University in Saudi Arabia and the German Aero- space Center. The project is funded by the U.S. Department of Energy’s Sun- Shot Initiative, which aims to reduce solar energy costs and expand the use of solar energy technologies through- out the United States. Sandia design engineer Josh
Christian said the on-sun testing at the solar tower will occur in two phases. First, researchers will test an insert designed by Georgia Tech that slows falling particles inside the receiver like a Pachinko board to in- crease the temperatures of the parti-
cles as they fall through. Later this summer, Sandia en-
gineers will remove the Georgia Tech insert from the receiver and evaluate free-falling curtain configurations.
Weather Factors Weather and other factors will
affect the pace of the testing. “New Mexico is great for this project be- cause our state has pretty consistent solar insolation throughout the year,” Christian explained. “However the biggest thing we need to know is how much power is going into the falling particle receiver. So a cloudy or hazy day is a big challenge for us. An ideal day for testing is a clear day with no clouds and no wind.” The tower at Sandia’s National
Solar Thermal Test Facility stands 200 feet tall and is the only testing fa- cility of its kind in the United States. Sandia National Laboratories is
a multi-program laboratory operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Mar- tin Corp., for the U.S. Department of Energy’s National Nuclear Security Administration. With main facilities in Albuquerque, New Mexico, and Livermore, California, Sandia has major R&D responsibilities in na- tional security, energy and environ- mental technologies and economic competitiveness.
