• Axiom Exergy has announced a partnership with Leap, a technology company that serves as an aggregator of flexible power loads in California. Axiom says the arrangement will unlock grid services revenue for its customers, including three Whole Foods Market facilities in Northern California.
Axiom'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 existing refrigeration systems to "store cooling" at night by freezing tanks of salt water.
"Axiom Exergy is excited to announce that Whole Foods has connected three of their buildings to our platform, which will serve as our first Virtual Power Plant," Axiom CEO Amrit Robbins wrote in a LinkedIn post Friday. "Axiom’s platform will intelligently manage 340 kW of dispatchable load across these facilities in order to generate more value for Whole Foods and to help stabilize California’s electricity grid."
• Sonoco ThermoSafe has announced a global partnership agreement with Cargolux for the leasing of the PharmaPort 360 temperature-controlled bulk shipping container. The agreement enables pharmaceutical shippers to lease PharmaPort 360 containers directly from the all-cargo airline based in Luxembourg.
• On LinkedIn this week, Ice Energy posted an update on its 5 MW contract with Riverside Public Utilities in California: "We are working to install 9 Ice Bear thermal #energystorage batteries and 13 rooftop units with Inland Mechanical Services Inc. at a car dealership in Riverside."
• A high-temperature thermal energy storage system inaugurated in Denmark this week stores heat in stones. The test system uses surplus wind power to generate hot air, which heats up small stones in an insulated container to 600 degrees. The stored heat is used to generate electricity when the wind doesn't blow. The system was developed by the energy company Seas-NVE, in collaboration with DTU Energy, Aarhus University Geoscience, Danish Energy, Energinet.dk and Rockwool.
• Alexium International CEO Bob Brookins was among the presenters at the International Conference on Textile Coating and Laminating in Berlin earlier this month. His topic: "Advanced applications of phase change materials."
• The German Aerospace Center (DLR) is investigating whether Germany’s coal plants can be refitted to serve as thermal energy storage sites. "The research body, which has a track record in concentrated solar power (CSP) development, is planning a pilot that will involve ripping out the boiler from an old coal plant and replacing it with a molten salt thermal storage tank that will be heated using excess renewable energy," Greentech Media reports. "If the concept works, then advocates say it could help safeguard coal generation jobs while giving Germany tens of gigawatts of storage capacity for renewable energy load-shifting on the German grid." DLR says it is preparing a commercial-scale pilot in association with an unnamed German utility.
