What is the best method to harness thermal energy storage in refrigeration systems?

Industrial refrigeration consumes more energy per cubic foot than any other utility load. Refrigerated facilities are energy intense and have a large peak demand. This demand creates significant impact on the grid. For an owner or operator, these facilities are expensive to operate. Thermal storage creates the opportunity to save energy and reduce or shift peak demand – resulting in energy cost savings. It also increases system resiliency.

Emerging methods of thermal storage can provide grid flexibility and save kWh. But the ability for these technologies to save kWh, and the magnitude of that savings, is still highly uncertain – especially in cold climates.

Slipstream is digging into three different methods for harnessing thermal storage in refrigeration systems.

  1. In food storage, using the static thermal mass of the stored product
  2. Applying Viking Cold thermal storage technology to harness tuned phase change material as thermal mass
  3. Using the existing refrigeration system in parallel with an active ice storage system
