Whats needed? 1.Interested, Enthusiastic People 2.Senior Management Support 3.Allocation of Resources (Money) PLUS … Some Measure of Luck / Timing!
Edinburgh: University in the City … invested £12million in Decentralised Energy / CHP Pollock Halls 526kWe CHP Kings Bldgs 2.7MWe CHP George Sq 1.6MWe CHP
Edinburghs 3 CHP Projects 1.Pollock Halls: 526kWe engine serving student residences as lead boiler – The Kings Buildings: 2.7MWe engine displaced old steam system + 2 new 7.5MW LTHW boilers serving high base load – George Square: 1.6MWe engine again replaced steam system – plus 75 tonne Heat Store and 600kW Absorption Chiller to even out load – 2005
UK Energy Flows – 50% wasted
Combined Heat and Power
George Sq: Trigeneration
George Square Energy Centre
George Sq buildings now linked:
First remove old steam boilers…
1.6MWe Alternator bolts on
High Efficiency, Low NOx Boiler
75 cubic metre Thermal Store
GE Jenbacher 612 Engine 12 cylinder Jenbacher Engine
600kW Absorption Chiller
