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.

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.​"

Viessmann’s ESyCool Green propane-based heat pump refrigeration system has been awarded the government-backed German Innovation Prize for Climate and Environment. The system includes an ice thermal storage component.

NOTE: You must be a Phase Change Matters subscriber to submit an entry. Representatives of organizations attending the first meeting of the PCM Industry Association of North America in October know the answer and are not eligible for this contest. Good luck to all the contestants!

Chocolate1. Mmm chocolate

We are exploring new ingredient technologies to produce a chocolate product that will release heat when it is consumed. Standard chocolate produces a minor cooling effect when it's melting in the mouth – the main fat is cocoa butter. The idea is to develop a new filling fat/oil that will release heat when consumed.

2. Premium padsWonder Woman

I represent a consumer goods company that is seeking materials that could help the feminine pad feel ‘cool’ in order to increase the comfort of use, especially when female is engaging in activities such as boxing, distance running and other extreme athletic challenges.

Chickens3. Chicken helper

I am hoping phase change materials could help solve a problem I have. First, I am completely serious. Second, here is the problem: I live in Texas and have 10 back yard laying hens. It is hot. Chickens start to go into heat stress at 85 degrees. Is it possible to enclose PCMs into a sort of pad for my chickens to rest near during the day?

Golden Girls4. Hot flashes

I am interested in using your product for a product I am developing for my design thesis. I am trying to make a responsive bra that senses a hot flash, and responds by turning on peltiers and "conducting" the cold through some sort of gel medium to the skin. Are any of your products the right thing for this?

Mosquito eggs5. Mosquito eggs

I'm wanting to ship mosquito eggs and need the parcel to stay dry, and within a prescribed temperature range of 10-35 degrees for up to three days. Would you be able to recommend a particular product of yours which could meet these requirements?
