On November 15, Viking Cold Solutions, a provider of thermal energy storage systems announced that an independent 3rd party energy management firm, ASWB Engineering, had completed a field demonstration study of the Viking Cold Thermal Energy Storage (TES) system on behalf of an unnamed Southern California utility.

According to Viking, the study verified a reduction in electricity consumption of 30% and 39% in two separate low temperature cold storage facilities in the San Diego area. The purpose of the study was to determine the effectiveness of Viking Cold’s system in cold storage freezer applications and to qualify the system for California utility inventive programs as part of the California Energy Commission Emerging Technologies initiative.

John Baffa, Professional Engineer at ASWB Engineering noted: “The benefits of the technology include reduced refrigeration equipment run time and increased product safety during power emergencies due to the thermal storage capabilities of the solution.”

James Bell, CEO of Viking Cold Solutions remarked:

“It is exciting to see our technology recognized by a leading utility energy efficiency program and I’m pleased that the study validates the results that Viking Cold customers already experience daily. Our passive, non-mechanical system is a cost-effective way to reduce energy consumption across the cold chain, from walk-in freezers to large distribution warehouses, which can be used stand-alone, or to boost the return with solar PV.”

Per Viking, two locations were studied by ASWB. The first test site, a walk-in freezer on Camp Pendleton in Southern California, showed a net facility energy savings of 30%.  The second test site is a commercial freezer warehouse at the Jacobs & Cushman San Diego Food Bank. By leveraging the Food Bank’s existing photovoltaic system to run the refrigeration during the day and using Viking Cold’s TES system at night, the facility showed a net energy savings of 39%.

Corey Rosenbusch, President and CEO of the Global Cold Chain Alliance (GCCA) commented: “Electricity costs are one of the top two expenses in the cold storage industry and this study demonstrates the value of using an intelligent Thermal Energy Storage system to reduce energy consumption in freezers. Based on these results, our membership should evaluate this technology for their own low temperature applications.”
