Summary
Veolia, is set to deliver wide-ranging energy projects to further decarbonize the heat supply at the University Hospital of Hartlepool. Designed to de-steam the current heating system and deliver guaranteed carbon savings of 2,179 tons per year, it will use a ground source heat pump and thermal store, combined with solar arrays to maximize energy efficiency.
Veolia has been managing energy at the hospital that provides patients with a wide range of diagnostic services, outpatient clinics and low risk surgery, since 2003 using combined heat and power, CHP. The new upgrades will use a combination of technologies to optimize efficiency and balance the electrical and thermal requirements.
The new scheme combines a 1,400kW ground source heat pump system, with a 70,000 liter thermal store, to optimize the efficiency of the system by operating the heat pump at a higher load, when it is most efficient, to charge the store and deplete it over several hours. To maximize efficiency and give N+1 redundancy the heat pump will use the supply from two boreholes, and will be supported by 1MWp of renewable electricity supplied from ground and roof mounted solar PV arrays.
