PCM briefing: Ice Energy seeks distributors in Australia, Mexico and Saudi Arabia; Thermetrics' new manikin can measure PCM effects

Ben Welter - Friday, August 31, 2018

• In an interview with Energy Storage Report, CEO Mike Hopkins discussed Ice Energy's plans to distribute its ice-based thermal energy storage technology in Australia, Mexico and Saudi Arabia. In June, the California company announced a $40 million cash infusion from Argo Infrastructure Partners to finance the delivery of Ice Energy's residential and commercial thermal storage contracts.

Thermetrics manikin ANDIThermetrics says its new ANDI sweating thermal manikin has the "unrivaled ability" to measure both positive and negative heat flux and to respond to changing environmental conditions with "unprecedented" speed and accuracy. The new manikin was unveiled this week at the 12th International Meeting of Manikins and Modeling, hosted by the Swiss research institute Empa, in St. Gallen, Switzerland. The manikin can be used to evaluate the thermal performance of apparel, blankets and seats, as well as quantify the cool-to-touch or warm-to-touch temperature-buffering effect in fabrics containing phase change materials.

Viking Cold Solutions says the thermal energy storage system the company installed at a 93,000-square-foot frozen food distribution center in Richmond, Calif., has reduced peak period energy consumption by up to 43 percent and reduced overall freezer energy consumption by 35 percent. Viking installed the system at the Dreisbach Enterprises warehouse earlier this year. Plastic panels filled with a proprietary salt hydrate are installed evenly throughout the warehouse atop the existing product racks. The PCM absorbs heat as it melts, allowing chillers to run less frequently and still keep the warehouse within a few degrees of the target temperature. The system also includes intelligent controls and sensors to optimize energy use and alert managers to temperature abnormalities, equipment failure and power outages.

PCM briefing: Shipping costs rise for chemical companies; Inventure to build plant in China

Ben Welter - Saturday, August 11, 2018

Viking Cold Solutions founder and board chairman Paul Robbins, who retired as president at Caribbean Shipping Services in July, says he plans to resume a more active role in the day-to-day operations at Viking. The Houston company makes TES systems that pair phase change material with intelligent controls and remote energy-monitoring software to reduce commercial refrigeration costs.  

Chemical Week reports that shipping costs are on the rise for chemical companies as capacity tightens and truck traffic shifts to railroads.  

Inventure Renewables of Tuscaloosa, Ala., is partnering with Wilmar International and Desmet Ballestra Group on a new manufacturing plant in China's Jiangsu province, the Birmingham Business Journal reports. Construction is expected to begin in 2019. The plant will use Inventure’s soap carbonate technology to convert low-value processing residues into uncontaminated free fatty acids.

Ed Brzytwa, the American Chemistry Council's director of international trade, has urged the Trump administration to remove all chemicals and plastics products, valued at $2.2 billion, from a list of Chinese goods subject to possible increased tariffs. In testimony before officials from the Office of the U.S. Trade Representative this week, Brzytwa said higher tariffs on those products “has the potential to harm America’s manufacturing renaissance and is counterproductive to U.S. economic interests.” 

• The program for the 13th Conference on Advanced Building Skins has been posted. The event will be held Oct. 1-2 in Bern, Switzerland. Last year's conference included at least 10 presentations on phase change material. "Phase change" appears just twice in this year's program. A presentation by Jose Manuel Montes Donaire of AKT II Envelopes, London, "Thermal tuning of envelopes and its use as a parametric design tool," will address the topic of energy buffering with phase change materials. A presentation by Annie Shaw of Manchester School of Art on the architectural potential of knitted textiles will explore "three-dimensional seamlessness and stretch, phase-change form-finding and form-fixing."

• Pillow talk: Phase change material is no longer enough. Manufacturers like Tulo and Blu Sleep are turning to titanium particles and essential oils in an effort to stand out it in the crowded pillow market.
