PCM briefing: Epsom salts for seasonal heat storage; Formato joins Microtek Labs

Ben Welter - Monday, April 16, 2018

Chris Sansom, an associate professor in concentrating solar power at England's Cranfield University, says that magnesium sulphate heptahydrate, or Epsom salts, could be a viable material for seasonal heat storage. Adding water to the salts causes a reaction that creates heat at around 80 degrees C, a good match for space heating and hot water. Sansom is developing a heat storage system for the university’s growing campus. Because the school's CHP system requires a temperature of 90 degrees C, a slightly different form of salt, magnesium nitrate hexahydrate, will be used.

PCM briefing: AI tool could transform chemistry; Peli BioThermal opens Tokyo service center

Ben Welter - Monday, April 09, 2018

An artificial-intelligence tool that has digested nearly every chemical reaction ever performed could transform the chemistry world, reports Nature. The tool, developed at the University of Münster in Germany, uses "deep-learning neural networks to imbibe essentially all known single-step organic-chemistry reactions — about 12.4 million of them. This enables it to predict the chemical reactions that can be used in any single step."

Pelican BioThermal plans to open a service center in Tokyo next month to service its reusable Credo Cube temperature-control shippers, including refurbishment and repair. The center will also serve as a network station for the company’s Credo on Demand rental program.

Patent application: Vessel assemblies for temperature control

Ben Welter - Monday, April 02, 2018

American Aerogel patent drawingU.S. patent application 20180086534 (applicant American Aerogel Corp., Rochester, N.Y.):

"This present disclosure provides a vessel assembly for use in temperature sensitive shipping that can maintain a payload temperature across a range of temperatures. Importantly, the vessel assembly of the present disclosure reduces the overall packaging materials used in a shipper box and prevents the 'wrong' mixture of PCM-containing vessels from being used. ...

Ben Welter - Sunday, March 18, 2018

Energy and Buildings has issued a call for papers for a special issue on energy storage for building applications. Topics include "bio-inspired, bio-based, and bio-replicated storage materials and systems," "storage-based systems for mitigating indoor-outdoor microclimate" and "smart, multipurpose, multifunctional materials for sensible and latent thermal energy storage in buildings." Dr. Luisa F. Cabeza of the University of Lleida is among the issue's guest editors. Papers will be accepted between May 1 and July 31. Original manuscripts only.

Nebuma of Saarbrücken, Germany, has introduced a thermal energy storage system that can store around 16MWh of heat in a 20-foot container. The company says the blocks or granules in the tanks can be heated to up to 1,300ºC “with an efficiency that is second to none."

PCM briefing: Maryland launches energy storage tax credit; Viessmann system wins German innovation prize

Ben Welter - Tuesday, February 27, 2018

• A business opportunity at the Pacific Northwest National Laboratory in Richland, Wash: "Acquisition of a thermal energy ice storage system (TESS) that will be integrated with an existing chilled water distribution loop serving one building." Bids are due March 8.

Stefan Braun, SmartCAE managing director• In a pair of LinkedIn articles, SmartCAE's Stefan Braun shares his company's approach to preparing PCM bricks for cold-chain shipments. "Our recommendation is to precondition PCMs outside the phase change range," he writes. "This way, the PCM bricks are always in a well-defined state, providing their full latent heat rather than some undefined fraction. A repeatable, well-defined preconditioning process is a prerequisite for a robust box design."

• The Maryland Energy Administration is accepting applications for its new Energy Storage Tax Credit Program, which offers up to $750,000 to residential and commercial customers who install qualified systems. "The rules specify that projects can store electrical energy: mechanical and chemical including electrochemical energy, in addition to thermal energy that 'was once electrical energy,' " Utility Dive reports. "The rules also say all storage systems must store energy either for use as electrical energy at a later date or in a process that offsets electricity use at peak times.​"

• Nantucket, Mass., has approved the installation of an Ice Bear thermal storage and air-conditioning unit in a building owned by the town. Last summer, Genbright won a $1.5 million grant from the state to install the units in more than 200 Nantucket homes, with the goal of reducing peak energy demand and staving off the need for a third undersea power cable for the island. But some residents voiced skepticism about the technology, prompting the town board to approve the test installation.

• Shippers have found that cocoa butter can be hard to contain on long ocean voyages. There have been reports of the material leaking out of containers as it changes phase, clogging bilges and generally making a mess. The Cargo Incident Notification System, established in 2011 to share information on all cargo-related incidents, has issued guidelines that recommend the material be shipped in refrigerated containers, particularly when passing through hot climate zones.
