Alternatively, a facility can use ‘off-peak’ electric power fees which are lower during the night to create ice, that may be included right into a making’s cooling procedure to lower demand for energy during the day. A patented cold thermal energy storage system from O-Hx works by using ice slurry https://purethermal.co.uk/media-news/pure-thermal-webinar-can-icebat-cold-thermal-energy-storage-provide-an-alternative-cooling-design-option/
