A thermal storage project in Northamptonshire, England, is expected to provide 47 new homes with hot water and heat via renewable energy sources such as solar power. The borehole technology, developed by Caplin Solar of Leicester, stores heat in the ground in warmer months for later use in colder periods.

• Packaging giant Sonoco of Hartsville, S.C., has announced the creation of its EnviroSense sustainable packaging initiative. EnviroSense products are designed to incorporate a number of elements associated with more sustainable packaging, including optimized package-to-product ratio; increased use of recycled and recyclable content; fiber sourcing; compostability; and the use of bio-based materials.

• Registration is open for Sonoco ThermoSafe's next Leading Minds Seminar, "Collaborative Learning that FUELS Your Temperature Sensitive Healthcare Products," to be held Nov. 14 in Amsterdam. The seminar is designed for European supply chain, logistics, quality and packaging professionals responsible for the protection and management of temperature sensitive healthcare clinical supplies and finished products.

• A projected tripling of heat-related deaths in the United Kingdom over the next 30 years will require a drastic rethinking of ways to cool buildings, a parliamentary select committee warns. “The risk of overheating in terms of minimising risks to health and safety of occupants should be enshrined into regulations for new build homes and retrofits," the Environmental Audit Committee said. "This should be considered alongside an integrated review of energy efficiency and ventilation, and be included in the government’s planned Future Homes Standard, to include improvement in the measurement of current and future overheating risk and prioritise passive cooling measures.”

PCM briefing: 'Awareness' of PCM technology seen as key challenge; researchers develop novel anti-icing material

Ben Welter - Friday, April 26, 2019

University of Illinois at Chicago researchers say they've developed a material that can inhibit the formation of ice much longer than existing technologies, New Atlas reports. The anti-icing material is made of phase-changing liquids that have heat-trapping properties. Researchers say the material works effectively in temperatures as low as -15° C.

Collin CokerIn an interview with Engineered Systems, Viking Cold Solutions' vice president of sales and marketing talks about the state of the thermal energy storage market and the company's PCM-based thermal storage systems. What's been the Houston company's biggest challenge over the past 18 months? "Awareness," said Collin Coker, right. "We constantly hear, 'This is really interesting; I've never seen it before; do you have fluid moving through the refrigeration system?' So, breaking it down and explaining that it’s non-mechanical and very simple is part of the challenge. Getting people to believe that this technology can provide savings in the range of 10-50% in some applications is also a challenge. A lot of folks are fairly guarded, because that level of savings has never been achieved in this industry before. It just seems too good to be true. "

• The World Bank announced a new program this week to accelerate the adoption of sustainable cooling technologies, including air conditioning, refrigeration and cold chain in developing countries. The program will provide technical assistance to ensure that efficient cooling is included in new World Bank Group investment projects.

Sonoco ThermoSafe has posted the agenda for the company's next Leading Minds Seminar, to be held May 29 in Princeton, N.J.

According to Tempur-Pedic: "At about 80°F, the molecules within TEMPUR-breeze’s most efficient Phase Change Material (PCM) to-date, PURECOOL+, activate, shifting from a solid to a liquid to absorb massive amounts of heat. For the first time, Tempur-Pedic’s scientists successfully altered these proprietary molecules to deliver more phase change material, increasing its capacity to absorb heat by 2x compared to other PCM."

PCM briefing: 2-day training school in Barcelona; Alexium to launch foam bedding, 'top of bed' products

Ben Welter - Friday, March 15, 2019

A training school on thermal energy storage material selection, optimization and characterization will be offered May 20-21 at the University of Barcelona. The university's Center for Design and Optimization of Processes and Materials is hosting the event. The fee is 230 euros. Lecturers include Camila Barreneche, Ana Inés Fernández, Mercè Segarra and Pablo Gamallo of the University of Barcelona; Luisa Cabeza and Alvaro de Gracia of the University of Lleida, Spain; and Yulong Ding of the University of Birmingham, United Kingdom.

Alexium International Group Ltd. was among the companies making presentations this week at the Gabelli & Company Specialty Chemicals Conference in New York City. Alexium, based in Greer, S.C., and Perth, Australia, makes flame-retardant and PCM-enhanced fabric treatments. Among its "cornerstone" initiatives is a plan to launch a new product line in early 2019, Alexicool FM, the application of the company's Alexicool technology to foam mattress and "top of bed" products.  

• Thermal materials specialist va-Q-tec reports that its annual revenue grew by 8 percent in 2018. The company, based in Würzburg, Germany, said sales from its products business, including vacuum insulation panels and phase change materials, increased by 12 percent to 20.1 million euros, up from 18 million euros in 2017. However, its earnings fell by 58 percent, to 3 million euros. It blamed earnings decrease on investment costs and a rise in sales from its lower-margin products business.

• Australian researchers are challenging the belief that 22° C (72° F) is the optimum temperature to maintain worker productivity. A team from Griffith University’s School of Engineering and Built Environment and Cities Research Institute performed an extensive review of research literature on the relation of moderate thermal environment to cognitive performance. "From the research point of view," the lead researcher, Fan Zhang, said in an interview with the Cooling Post, "there is no empirical evidence that this temperature [22ºC] should be maintained. In effect, it is inconsistent with the already-established comfort benchmarks such as ASHRAE 55-2017, which recommends a summer time thermal comfort zone of 23-26ºC. I would say 23-26 is a safe summer temperature set point range for western developed countries."

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

• 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.

MIT researchers have developed a way to use light to trigger the storage and release of waste heat from car engines and other sources. "Once melted and activated by ultraviolet light, the [phase change] material stores the absorbed heat until a beam of visible light triggers solidification and heat release," Phys.org reports. "Key to that control are added molecules that respond to light by changing shape from one that impedes solidification to one that permits it."
