PCM briefing: Boston food bank installs Viking Cold TES system; 2-day workshop on microencapsulation

Ben Welter - Friday, March 08, 2019

The Greater Boston Food Bank is reporting a 75 percent reduction in energy use during targeted peak hours since the beginning of the year after installing a Viking Cold Solutions thermal energy storage system for the refrigeration units at its 117,000 square-foot, high-efficiency Yawkey Distribution Center.

Maria Telkes• To mark Women's History Month, 24/7 Wall St. has compiled a list of "50 Things You Never Knew Were Invented by Women." MIT researcher Maria Telkes, a pioneer in the field of solar thermal storage, is on the list at No. 30. She created the first solar-heated system for her home in Dover, Mass., in 1947. The system used a phase change material, sodium sulfate decahydrate, to store solar heat.

• Researchers at the Chinese Academy of Sciences say they have developed an inexpensive, flexible film that renders the objects it covers virtually invisible in infrared light. The film's main components are DuPont's Kevlar, a synthetic fiber with high tensile strength, and polyethylene glycol, a phase change material that can store heat. 

• French utility ENGIE has begun production at one of South Africa’s largest renewable energy projects, the 100MW Kathu Solar Park. The concentrated solar plant's molten salt storage system provides up to 4.5 hours of thermal energy storage.

• The Southwest Research Institute is hosting a two-day workshop on microencapsulation March 25-26 in San Antonio, Texas. The introductory course will cover topics such as atomization (spray drying, spray chilling, spray congealing) and spray coating (fluid bed coating, granulation). The cost is $950.

• The University of California is winning praise for its decision to end its subscription deal with Elsevier, the world’s biggest publisher of scientific journals. UC is the first major university system to push for open-access publishing. UC, which had been paying $11 million a year to Elsevier in subscription fees, generates about 10 percent of the research produced in the United States. “It’s ridiculous that, in this age of the internet, researchers are paying huge fees for access to academic papers and for publication of their own work,” the San Jose Mercury News said in a March 6 editorial.
