PCM briefing: TES tank cuts cooling costs at Shippensburg; flow chart shows how all energy in U.S. is used

Ben Welter - Friday, August 12, 2016

• Inventor-entrepreneur Saul Griffith has developed a really, really detailed flow chart showing how all the energy in the United States is used. "This is really the first time that all of this data is brought together in one flow diagram, which is important if you really want to understand the consequences through the whole economy of things like defense," Griffith says.

Bill Gould, chief technology officer at SolarReserve, explains why he believes in the future of concentrating solar power with thermal energy storage. "CSP with storage is set to realize falling installation costs as global deployment accelerates," he writes. "It is a relatively young technology, with a strong roadmap for performance improvements, optimization and cost reduction. Future projects are already seeing 30 percent reductions in capital costs."

Viking Cold Solutions, maker of a PV/PCM cooling system, is generating sales leads with an offer of a free energy analysis to owners of supermarkets and cold storage warehouses.

• The new 3,000-ton high-efficiency cooling plant at Shippensburg University in Pennsylvania features a 1.7-million-gallon thermal energy storage tank. The tank stores water chilled during off-peak hours and provides up to four hours of full-load capacity without mechanical cooling. The system cut energy consumption during last year's cooling season by 12 percent — despite an 11 percent increase in cooling degree days.
