Having in a previous life installed a 400Kwp Solar array onto a cold storage facility, I know well the phenomenal energy demand for refrigerated retail, transport and storage. This looks a brilliant solution to shift the demand and usage, beyond just time-shifting electricity demand. It would be interesting to see the numbers.
Whilst we're still not seeing any real level of take up in energy storage at the C&I scale, this could be something to kick start the appetite. Just as my 400kwp solar array was at the time the largest rooftop solar in the north of England, and one of the early fully funded PPA projects, and is now just a small array in the great scheme of things. We need this sort of innovation and reference project, as we sure have a significant retail/cold storage electricity demand to address in Europe.
"By deploying refrigeration battery systems, these locations can convert power-hungry refrigeration systems into intelligent ‘batteries’ that can respond dynamically to the needs of the facility and the grid operator, taking into account energy prices, weather patterns, and grid programs like demand response," Robbins said in a statement. The $5 million project could provide up to 8 MWh of energy. According to Axiom, its refrigeration battery can shift six hours of a building’s refrigeration-based electricity loads by utilizing the existing refrigeration system’s excess capacity to “store cooling” at night by freezing a tank of salt water and then using the frozen tanks for cooling during afternoon hours.
