The UV-activated thermal energy storage material shows the rapid crystallization and heat discharge upon visible light (blue LED) illumination. (Grossman Group at MIT)MIT researchers have combined conventional phase change material with an organic compound that responds to a pulse of light. "The new system," MIT News reports, "uses molecular switches that change shape in response to light; when integrated into the PCM, the phase-change temperature of the hybrid material can be adjusted with light, allowing the thermal energy of the phase change to be maintained even well below the melting point of the original material." The system could be used in a thermal battery to store heat from the sun or any other source and release the heat when needed.

Patent application: Temperature regulating polyurethane gels

Ben Welter - Thursday, August 03, 2017

U.S. patent application 20170210961 (applicant Technogel Italia, Vicenza, Italy): 

"A method for the production of a temperature regulating polyurethane gel composition and corresponding articles includes fatty acid esters as a phase change material (PCM) directly incorporated in the fluid phase of a polyurethane gel without encapsulation. The liquid or melted PCM is solved in the polyol component of the gel and is able to crystallize and melt within the gel structure reversibly. The polyurethane gels are under-crosslinked and include at least nominal three functional ethylene oxide-comprising alkylene oxide polyether polyol with 0 to 40% EO and an isocyanate with an effective functionality of from 1.5 to 3.5. The gels are useful in articles where the gel can be positioned close to the human body for temperature regulating purposes, and especially to improve the sleeping comfort of a resting person."

PCM briefing: 'New paradigm' in pharma cold chain; opening for sales manager at Sonoco ThermoSafe

Ben Welter - Monday, July 24, 2017

GoSun solar stove• The makers of the GoSun portable stove, which uses solar energy to bake, roast or steam food at temperatures up to 290° C, have raised nearly $400,000 from investors on seedinvest.com. The stove initially used high-temperature phase change material to store the sun's energy. "We abandoned the PCM a couple years ago after we started doing testing with it," said GoSun's Matt Gillespie. He said the material did not match the performance promised by the PCM maker, degrading "significantly" after just a few cycles. The current design uses compound parabolic reflectors and a horizontal vacuum tube to convert nearly 80 percent of sunlight into usable heat. The Cincinnati company has sold 10,000 stoves online and in retail outlets such as Home Depot, REI and Cabela's. GoSun plans to use the SeedInvest funds to support continued growth.

Ben Welter - Friday, May 19, 2017

Drawing of Outlast Xelerate

Outlast Europe's Martin Bentz spoke with T.EVO magazine this month about the company's new Xelerate fabric. The fabric, introduced at a German trade fair earlier this year, incorporates "heat spreader" technology, a process traditionally known for cooling electronic devices. Xelerate fabric features improved thermal conductivity, Bentz said, and is suitable for home textiles, sportswear and protective gear. In an email exchange with Phase Change Matters, Bentz declined to discuss specific partners or customers.

Warmilu, maker of the IncuBlanket infant warmer, reports that is on track for $300,000 in total 2017 sales after signing two distributors for Latin America, Africa and Southeast Asia: Relief for Africa Foundation and Maternova.

PCM briefing: California utility will buy up to 100 Ice Bears for residential use; Malouf unveils new graphite-PCM pillow

Ben Welter - Thursday, February 09, 2017

Ice Energy will join forces with the Southern California Public Power Authority to provide up to 100 Ice Bear 20 cooling units for residential use within utility's 12 member territories in 2017. Installations will begin in June. The Ice Bear 20 stores cooling energy during off-peak hours by freezing water in an insulated tank. During peak hours, the company says, the stored ice delivers up to four hours of cooling, reducing the typical peak load by 95 percent. The new deployment is designed to demonstrate the Ice Bear 20's grid value to utilities. The units will be installed in single-family homes chosen by Ice Energy based on site visits. Homes that need 4-, 5- or 6-ton air-conditioning systems replaced are the likely targets. The utilities pay for the Ice Bears; it's unclear at this point who will pay installation costs. If all 100 Ice Bear 20s are purchased, the total cost to the utilities will be $1.33 million (not including installation).

Malouf CarbonCool pillow• Bedding maker Malouf's new CarbonCool Plus OmniPhase pillow combines the temperature-regulation properties of graphite and microencapsulated phase change material. "At the molecular level," Furniture Today reports, "the material inside the capsules changes from a solid to a liquid when the temperature is high and vice versa when the temperature is low. This continuous cycle is designed keep the pillow surface between 87 and 91 degrees, which research shows is the ideal skin temperature range for deep sleep." The queen size shown here retails for $299.99.
