Solar + Thermal Energy Storage

Solar energy is, by some studies, the cheapest form of electrical energy generation, as well as the cleanest, delivering exceptional benefits for both the planet and for businesses. Yet, in order to maximize the return on solar requires an efficient way to store that energy and flexibility for its future use.

Viking Cold has developed the only proven, environmentally friendly way to store solar energy in the cold storage market (the highest energy demand per cubic foot of any industrial category). Review the third-party Emerging Technologies Coordinating Council Study.

The solution is the combination of solar generation and Thermal Energy Storage (TES). Our TES system allows you to store solar energy in the form of cold and then release that energy when it’s most cost effective.

The Viking Cold TES system has no mechanical components and is the perfect solution to managing demand and solar shift (the “duck curve”) for your facility. We leverage the existing refrigeration equipment to minimize energy costs while simultaneously maintaining temperature control.

Learn how PV Generation + Thermal Energy Storage reduced overnight grid usage by 95% and reduced overall refrigeration energy consumption by 39% at the San Diego Food Bank’s 90,000 square foot warehouse.


Protection From Rising Peak Energy Charges

Viking Cold’s System stores thermal energy during low cost periods of the day and uses it during high cost periods of the day saving you up to 90% of peak demand charges.

 Protection That Lasts

The Viking Cold solution is designed to last 20 years, has no moving parts and is maintenance free. Unlike competing products, the system is easy to install and works alongside your existing refrigeration equipment.

 Thermal Backup Protection

When the power goes out or mechanical systems fail, Viking Cold systems keeps your facility cold. Your business is protected from costly product loss.

 Protection In Real-time

Our monitoring and reporting system provides predictive tools to protect your business. When refrigeration begins to degrade, alarms provide early warning before expensive problems arise.

 Protection For Your Bottom Line

Viking Cold Solutions™ will work with your company to install a system tailored to your business, with many flexible purchase options to protect your balance sheet.

reduced electricity costs, lower utility bills 4 Thermal Energy Storage Benefits That Will Improve Your Bottom Line

Viking Cold’s Thermal Energy Storage (TES) has many benefits for commercial businesses with high refrigeration based loads. Here are four of the main benefits that TES can provide. 1. Big Savings Imagine a world where gasoline costs $3 per gallon, but you could buy the same gasoline at night for $.75 per gallon. What time of the day would you buy your gasoline? You probably would buy the $.75 per gallon gasoline at night, store that energy in your gas storage tank and then use it during the day.

refrigerating elements ceiling The Thermal Energy Storage Revolution Has Begun

A new report from GreenTechMedia finds that energy storage capacity in the United States grew 243 percent last year – a sign the clean-energy revolution is here. According to GreenTechMedia, 112 megawatts of energy storage were deployed in the fourth quarter of 2015. This was more than the combined total of all storage added in 2013 and 2014. We’re in a revolution with energy storage systems rapidly expanding across the country. What’s driving this?
