4 Cold storage for emergency cooling systems. Due to the short discharging times of the sp.ICE, the ice energy storage is ideal for emergency cooling systems that have to react particularly quickly. The sp.ICE in the 10ft container version can supply a server room with a cooling requirement of 25kW with cooling power for over 40 hours.
Cited by 6 | Viewed by 2320. Abstract. In South Korea, renewable energy policy is mainly focused on electricity and tends to neglect renewable heat (RH). However, for the purpose of reducing greenhouse gas emissions, the heating sector must sharply switch from its use of conventional fuels to renewable sources.
