PCM briefing: Viking Cold Solutions lands deal in Phoenix; study finds ARPA-E is doing what it was designed to do

Ben Welter - Monday, June 19, 2017

Viking Cold Solutions has announced a collaboration between Salt River Project and Bashas' Supermarkets to install and evaluate the performance of Viking's PCM-based thermal energy storage system at Bashas' distribution center in the Phoenix area. The system is expected to significantly reduce energy costs by shifting peak demand to nighttime hours.

A six-year study finds that ARPA-E, the U.S. Energy Department program that supports cutting-edge energy technologies, is meeting the goals of the 2007 law that created it even as the Trump administration seeks to eliminate its funding. The National Academies of Sciences, Engineering and Medicine report concludes that the program is moving in the right direction and does not require major changes to keep bringing new energy technologies to market.

Ice Bear 20 gets high marks for energy efficiency in third-party tests

Ben Welter - Friday, June 09, 2017

Ice Energy reports that its Ice Bear 20 home cooling and energy storage system has achieved a Seasonal Energy Efficiency Ratio (SEER) of 14.56 when operating like a conventional AC unit. Not bad. But the unit's Energy Efficiency Ratio when operating in ice cooling mode is a remarkable 150. According to CEO Mike Hopkins, that is "more than three times greater than the next best rating we could find, which is a geothermal system with an EER of 46." Many wall air conditioners now in use have an EER of around 10.

During off-peak hours, the Ice Bear stores cooling energy 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.

Large-scale manufacturing of the Ice Bear 20 is set to begin this summer to fulfill utility-sponsored programs in California and Massachusetts. Later this year the product will be made available directly to homeowners in California, Hawaii, Australia and the Middle East.

PCM-enhanced table selected for French accelerator program

Ben Welter - Friday, June 09, 2017

Table ClimatiqueA table designed to reduce energy costs by absorbing heat when indoor temperatures rise above a comfortable level is among 25 innovations chosen for FAIRE Paris, an accelerator program supporting "innovative urban design and architecture projects" in France. 

"Table Climatique," designed by Jean-Sébastien Lagrange and Raphaël Ménard, contains microencapsulated Micronal phase change material within triangular folds of lightweight anodized aluminum. The PCM has a melting point of 22º Celsius. It releases heat when temperatures fall below a comfortable level.

"The waved geometry of the conductive aluminum fosters thermal exchanges between the room and the PCMs located inside the Climatic Table," according to the creators' website. "The folds of the light-weight sheet of aluminum give also an excellent structural rigidity and carrying strength. Thus, the plateau might have a very large span."

Ménard and Lagrange hope to develop a line of "zero energy furniture" products based on the table.

Roccor LLC of Longmont, Colo., is using phase change material in a device designed to manage internal heat in low-orbit satellites. “We have one product with paraffin wax inside a flat structure. When the spacecraft is hot, it dumps heat into that paraffin wax and turns that into a liquid — basically a store of energy,” Chris Pearson, Roccor’s vice president of space programs, said in an interview with Via Satellite. The heat is later released into the satellite to keep temperatures stable.

Axiom Exergy system installed at Whole Foods in California

Ben Welter - Friday, April 28, 2017

Axiom Exergy has completed the first installation of its thermal storage system at a Whole Foods Market store in Los Altos, Calif.

In just three years, notes Greentech Media, Axiom has transitioned from a garage startup to a revenue-generating company with a major supermarket customer.

Axiom system integratorAxiom's "Refrigeration Battery" system is designed to reduce a supermarket's peak power use by up to 40 percent and provide backup cooling during power outages. It uses the excess capacity of a customer's existing refrigeration system to "store cooling" at night by freezing tanks of salt water. The frozen tanks supply refrigeration to the building during periods of peak demand, reducing the need to run energy-intensive compressors and condensers.

The "passive retrofit" at Whole Foods did not require modification of the store's existing refrigeration system. The thermal storage tanks were placed in the loading dock area behind the store, and Axiom's system integrator was installed next to the compressor racks in the mechanical room. Axiom says the system has successfully charged and discharged 1040 kWh of load for up to 10 hours a day over the course of several months.

"We are proud to be leading our industry by being the first to use such an innovative technology to shift our large refrigeration-based energy loads to off-peak hours," said Tristam Coffin, director of sustainability and facilities at Whole Foods.

Ellen gives away Ember mugs

Products that tap the power of phase change material have appeared on network television before, taking star turns on "Shark Tank" and "Superstore." But until this week, a thermal-management product had never generated howls of appreciation from an audience.

The Ember temperature-control coffee mug was among the high-end products given to cheering audience members on Thursday's episode of "The Ellen DeGeneres Show." The $150 mug, introduced last fall, is sold online and in select Starbucks stores in the United States. It uses phase change material and a microprocessor-controlled heating system to maintain hot beverages at temperatures set by the user.
