Innovative thermal energy storage technologies (Vincent O'Brien)

  1. 1. Innovative thermal energystorage technologiesVincent O’BrienCopper Industries (Ireland) LtdVincent@copperindustries.co.uk
  2. 2. Copper Industries and UUcollaborationsUniversity of Ulster’s Centre forSustainable TechnologiesCopper Industries (Ireland) Ltd• Based in Toome, Northern Ireland• Manufacturer of hot watercylinders, buffer vessels andthermal stores from domestic tocommercial/industrial scale withover 13 years of experience
  3. 3. Introduction to hot watersystemsSystem types• Domestic hot water• Low temperature hot water heatingsystems• Combined but separate systemsSystem options• Direct/indirect• Vented/unvented• Gravity fed/mechanically pumpStorage issues• Safe storage and supply temperature• Legionnaire’s disease and bacterialgrowth• Efficient energy transfer and storage• Material compatibility/suitability
  4. 4. The need for changeEnvironmental focus• A higher recognition of the needfor the responsible use of energySocial focus• Fuel poverty and higher fuel costsCustomer focus• Quality product providing fast,efficient hot waterMarket focus• Effective integration of renewablesinto new build and retrofitinstallations
  5. 5. Copper Industries and UUcollaborationsInvest NI Innovation vouchers:• MaxiPod – thermal store• HotHead – stratifying cylinderKnowledge Transfer Partnership todevelop an innovative thermal energystorage system for future/renewabletechnologies through theestablishment of a novel R&D facility
  6. 6. The MaxiPod thermalstore - description• Maintains the store attemperature• Instantaneous response to heatingand hot water demand• Mains pressure hot water• Indirect hot water supply reducesthe risk of exposure to Legionella• Efficient multi-fuel system
  7. 7. The MaxiPod thermalstore – performance• “Can provide up to 38 kW ofdomestic hot water demand whilestill maintaining suitable flow ratesand volumes that would besuitable to satisfy all appliances ina modern domestic setting.”• “Simplifies the method by whichconventional fossil fuel andrenewable heating systems can beintegrated to provide both spaceheating and domestic hot water,whilst reducing the potential oflegionella infection.”
  8. 8. The HotHead stratifyingcylinder - description• Rapid and efficient response tovarying levels energy inputs,durations and flow rates• Energy is delivered where it ismost useful• Decreases start-up and recoverytimes
  9. 9. The HotHead stratifyingcylinder - performance• “exhibits significantly increasedstratification”• When tested using an evacuatedtube solar collector, there was a“4% increase in the efficiency ofthe solar collector”• More rapid response to inputenergy• The hottest part of the cylinder iscloser to the point of use and notthe coil
  10. 10. KTP projectCurrently commissioning acomprehensive in-house test facilitywith the capacity to characterise:• Charging• Discharging• Re-charging• Storage• Heat exchanger performanceFor:• Vented• Unvented• Direct• Indirect• Renewable integration
  11. 11. Where to next?Improved heat exchanger performance• Faster response• Safer supplyImproved cylinder storage• Stratified storage• Improved retention• Optimizing multi-fuel interactionsNew materials and applications• Potential of cost effective phasechange materials• Integrating renewable energieswith combi-systems
