PCM briefing: Trump budget 'just not correct' on ARPA-E; Croda's Kevin Bozec among panelists at Plant Based Summit

Ben Welter - Thursday, March 30, 2017

Ice Energy and Horizon Solar Power have completed the installation of a solar-plus-ice-battery-storage system at Palm Springs Cultural Center in California’s Coachella Valley. The system, which replaced an aging HVAC system, comprises 73.6 kW of solar panels and five Ice Bear 30s.

• The Trump administration's budget blueprint is "just not correct" about the function of the Advanced Research Projects Agency-Energy, its former director said this week. The blueprint eliminates all ARPA-E funding "because the private sector is better positioned to finance disruptive energy research and development and to commercialize innovative technologies." But agency was created just for stages of research and development that the private sector does not finance, said Ellen Williams, the agency's director from 2014 until January 2017.

Dow Chemical and DuPont won the blessing of the European Union for their $130 billion merger by agreeing to sell substantial assets, including key research and development activities.

• The global PCM market is expected to see a compound annual growth rate of 19.9 percent over the next five years, according to a new market research from Mordor Intelligence, "Global Phase Change Material Market-Segmented by Material Type, Product Type, Application, and Geography-Trends and Forecasts (2017-2022)." 

Kevin Bozec, marketing coordinator at Croda, is among the presenters at the Plant Based Summit in Lille, France, April 25-27. He will discuss Crodatherm phase change materials in a session on new materials. To register for the conference and trade show, visit www.plantbasedsummit.com.

Technically speaking, PCM-infused lingerie line radiates an air of mystery

Ben Welter - Monday, February 13, 2017

Giapenta's beautiful new line of PCM-infused lingerie features soft, breathable mesh, delicate appliques and natural, moisture-wicking fabrics. As far as technical details, though, the brand’s founder is leaving much to the imagination.

Giapenta modelThe Florida startup, which launched a Kickstarter campaign last month to cover costs of its first production run, says the TempPro fabric used in the lingerie “proactively” pulls heat away to cool the body. Giapenta’s message to consumers:

“Just as you start to get warm, the phase changing materials in the fabric actively pull heat away from your body. Overheating and sweating are reduced. If you do start to get cold, stored heat is released back to you, when you need it the most.”

The company was founded by Kris Strouthopoulos, who managed Sleep Number mattress and bedding stores for 10 years. That’s where she became familiar with temperature-regulating fabrics and materials.

“Women especially would always come up to me to tell me how amazing and life changing the fabric was for them,” she said. “I always thought that if they were getting such an amazing benefit from this technology all night long, why not get the same effects during the day from their undergarments? So that is how we initially got into the lingerie industry and built a team dedicated to infusing technology and smart design solutions into garments to help improve the lives of others.”

TempPro fabric illustrationShe and her sister, Marketing VP Elena Strouthopoulos, have been working on the brand for two years. The Kickstarter campaign met its modest target of raising $25,000 in just one day, putting the company on a path to complete the production run in Canada by April and ship the first orders in May.

I contacted Kris Strouthopoulos to learn more about the TempPro fabric, which the company says is used throughout the line. What type of phase change material is used? What is its melt point? How is it encapsulated? She politely declined to answer any questions of a technical nature, saying such information is proprietary. Fair enough. We'll leave that to your imagination.

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.

The 3-liter bag comes with two sets of PCM cooling packs. It's available on Amazon.in for about $52. In an interview with Express Pharma, company director Samit Jain talked about the Prongo and another new product, Celsure, a passive shipper designed to keep pharma products "at the right temperature for 96 hours and beyond at the tropical temperatures that countries like India, South East Asia and Africa have."

1414 Degrees, the Australian company that has developed a way to store electricity as thermal energy by heating and melting containers full of silicon, is now scaling up the technology and plans to launch the first commercial systems this year. Executive Chairman Kevin Moriarty said the company is waiting for AusIndustry, a division of Australia's Department of Industry, Innovation and Science, to sign off on the 10MWh project in February so manufacture can begin.
