Viking Cold Solutions enables companies to achieve up to a 35% or greater reduction in energy costs through efficiency and energy storage flexibility.

Thermal Energy Storage (TES) leverages phase change material to store energy in the form of cold for future use. It is engineered to freeze/thaw at specific temperatures commonly used in frozen cold storage (-20°F to 32°F or -28°C to 0°C). This allows the refrigeration equipment to be turned off for long periods of time (up to 13 hours) while maintaining stable temperatures in the freezer.

Our TES system works well for new construction, retrofit, or refurbishment projects.

We save our customers 20 to 35% or more on their energy costs (some up to 50%). TES adds efficiencies and flexibility to existing refrigeration systems to avoid peak pricing, reduce overall load, and reduce net consumption. Now cold storage operators and grocery stores can buy, store, and use their energy when it's most economical for them.
Thermal energy storage stabilizes temperatures by reducing the number of temperature fluctuations, dramatically slowing the temperatures' rate of rise, and providing thermal back up resiliency to maintain temperatures 3X longer in the event of a power outage or equipment failure.
TES improves the efficiency of existing refrigeration systems in many ways. 1) increasing the percentage of refrigeration run time during hours with lower ambient temperatures 2) running the compressors at maximum designed efficiency levels 3) consolidating up to 85% of the heat infiltration directly in the refrigeration air flow 4) no additional mechanical components or parasitic energy consumption 5) the PCM’s higher heat transfer rate (eight-times that of frozen food). All of this means more heat is removed using less equipment run time and an average of 26% fewer kWh.

Viking Cold Solutions Strengthens Community Bonds with Holiday Volunteer Effort at Houston Food Bank

Continuing our tradition of giving back, Viking Cold Solutions volunteered at the Houston Food Bank over the holiday season.  The team rolled up their sleeves to tackle a variety of tasks, from building and breaking down boxes to packing essential food items for local pantries.  Pallets of goods were transferred to assembly lines, and the kitchen buzzed with activity as a holiday lunch was prepared for those in need. The Houston Food Bank is a solution to both hunger and food waste.  Around 1 million people in the 18 southeast Texas counties served by Houston Food Bank are considered food insecure – lacking consistent access to enough nutritious food to fuel a healthy life.  To address this challenge, the Houston Food Bank distributes food and other essentials through a network of more than 1,600 community partners.  In addition, the food bank provides programs and services aimed at helping families achieve long-term stability which include nutrition education, health management, and help in securing state-funded assistance and other services. At Viking Cold Solutions, we believe in paying forward our good fortune by supporting food banks across the globe with our Thermal Energy Storage technology.  This innovative solution reduces energy costs and allows food banks to allocate more resources toward serving their communities.  The most recent addition to Viking Cold Solutions food bank portfolio includes Feeding Northeast Florida.  We completed a project for Feeding Northeast Florida in December just in time for the holidays and the New Year season.  By providing food banks with sustainable technology, Viking Cold Solutions helps organizations like the Houston Food Bank and Feeding Northeast Florida to extend their reach and increase their impact in the fight against hunger.

Thermal Energy Storage: Shaping the Future of Demand Management & Renewable Energy

Renewable energy has long been synonymous with wind and solar — sources derived from nature’s ability to create energy that emit zero greenhouse gases.  Today, Thermal Energy Storage (TES) is emerging as a critical component of the renewable energy landscape, standing alongside wind and solar as part of the solution for a cleaner, more resilient energy future. At this year’s Energy Efficiency Policy Forum, put on by the American Council for an Energy-Efficient Economy (ACEEE), demand response and virtual power plants (VPPs) were key topics of discussion, with Thermal Energy Storage increasingly recognized as a vital component.  TES provides a reliable and cost-effective means of storing and releasing energy as cold or heat, helping balance supply and demand.  By integrating with distributed energy resources like solar and wind, TES enhances the efficiency and flexibility of VPPs, storing excess renewable energy for later use, reducing grid strain, and improving energy resilience. The ACEEE is a nonprofit focused on advancing energy efficiency to foster economic growth and address climate change which is committed to reducing energy waste, supporting equitable economic opportunities, and improving public health and the environment.  This year’s Policy Forum centered on shaping federal energy policies, with discussions on building efficiency, transitioning industries to low-carbon practices, and enhancing electric vehicle and freight systems.  The forum aimed to influence policies that strengthen U.S. competitiveness and address climate challenges. Inspired by the discussions at the Energy Efficiency Policy Forum, Viking Cold Solutions leadership team took these learnings to the subsequent Department of Energy’s Deploy 24 Conference.  The focus of the DOE conference was on accelerating the deployment of critical energy and decarbonization technologies, such as TES, across the U.S.  At both events, Viking Cold engaged with policy makers, utility companies, and developers, exploring the growing opportunities TES offers for increased utilization of renewables.  Viking Cold Solutions is ready to partner with our customers and ensure they achieve their sustainability goals.
