14 14 Some of The Challenges Space where do you find a spare 12,500m 3 in an urban context? (equivalent to 5 Olympic swimming pools) Finding the correct balance: installed chiller capacity v storage volume Ice storage: reduced volume v increased carbon Operational cost, reliability, longevity, system complexity Electrical Infrastructure: benefit v diversity risk Intermittent occupation: operational diversity v installed capacity

15 15 The Value of Thermal Storage Establish the value early and integrate into master planning and early design The holistic benefits to complimentary infrastructure (capacity and time of day load management) Thermal Utilities with storage: on the agenda in an urban regeneration environment, and looking for opportunities to expand into community developments Providing value to people: economic, reliable, flexible, Place making: Centralised Utilities can free up roof tops for other urban activities and greening
