PCM briefing: Traction battery for electric vehicles; Ember mug available in Apple stores

Ben Welter - Friday, October 19, 2018

• The Fraunhofer Institute for Structural Durability and System Reliability in Darmstadt, Germany, has developed a traction battery that can use thermal energy as a heat source in electric vehicles. A new type of fiber-reinforced composite sandwich housing protects the battery from temperature fluctuations. The phase change material composite system is designed to precondition the battery at low outside temperatures and reduce heat generation during rapid charging. The system was developed as part of the European Union's Optimized Energy Management and Use project. "We've developed material, structural and process technologies that can guarantee drivers a more reliable and uniform range for their battery-powered vehicles," said Felix Weidmann, project manager at Fraunhofer LBF.

Airec AB of Sweden has joined the EU Horizon 2020 project SWS-Heating. The project's goal is to develop seasonal thermal storage of solar energy. The energy will be stored in phase change materials. Airec will develop heat exchangers for the project. 

A process for extracting a biodegradable polymer from crustaceans is among the winners of this year's Green Chemistry Challenge Awards. The awards were formerly known as the Presidential Green Chemistry Challenge Awards. The American Chemical Society’s Green Chemistry Institute has collaborated with the U.S. Environmental Protection Agency to manage the awards since their inception in 1995. The EPA dropped out this year, citing long-term certainty about the program’s financial situation.  

Ember temperature-control tumblerEmber Technologies' temperature-control mugs are now available in Apple stores and on apple.com. The travel version right, uses phase change material to bring hot beverages down to a drinkable temperature. Earlier this year, Nordstrom began selling the mugs online and in Nordstrom popup stores.

Capstone Turbine Corp. and Argonne National Laboratory have received funding from U.S. Department of Energy to refine Argonne’s high-efficiency, fast-charging and fast-discharging thermal energy storage system for use in combined heat and power systems. The system, originally developed for use in concentrated solar power applications, will use phase change material to capture waste heat from industrial manufacturing processes. The goal is to integrate Argonne's technology into a Capstone C200 CHP system.

• At the World Energy Engineering Congress in Charlotte, N.C., this week, Mark Richards of Phase Change Energy Solutions reports that the company demonstrated "a mini PhaseStor tank in action with 1/2 ton chiller and small heater (system hand made by Scott Queen) to charge and discharge the tank and includes on board DAQ system to show tank thermal performance." Richards presented at a panel discussion Friday, "Justifying HVAC Energy Savings in Buildings Using Phase Change Materials - A Debate with a Skeptical Engineer." Also presenting were Guy Frankenfield, energy division manager at DN Tanks Inc. ("Thermal Energy Storage - Uncovering the Value of Ice and Chilled Water TES Systems") and Ice Energy CEO Mike Hopkins ("Thermal Energy Storage in Package Units? Yes, it is Here").
