The connection of the Valladolid Clinical Hospital to a biomass heat network presents its candidacy for the Expobiomasa 2019 Innovation Award

Connection of the Valladolid Clinical Hospital to a heat network with biomass

The biomass heat network installed at the University of Valladolid supplies 90% of the energy demanded by the Clinical Hospital y saves the emission of 3.000 tons of CO2 year. The complex, which demands 12 millions of kWh every year, thus becomes the Spanish hospital with the highest percentage of thermal demand served by renewable energy. The rest of the power that the building requires is serviced with the old natural gas boilers, it had 5 boilers that added 11MW. The connection was made on January 16 of 2019.

The total budget allocated for the project was 1,18 million euros, an action that is amortized against the economic savings generated while reducing the hospital's energy bill by five percent.

The connection to the heat network of the Grape involved several technical actions:

  • El increased thermal power installed in the boiler room, it has gone from 14,1 MW of power to 19,1
  • La distribution network extension of energy A new branch of pre-insulated pipes from the IBGM building to the boiler room of the hospital.
  • And to hydraulically decouple the circuits and perform the delivery of thermal energy in the conditions of power and temperature demanded by the Hospital, a new thermal exchange substation of up to eight megawatts in the premises of the complex.

The project is part of the «savings, sustainability and energy efficiency» policy. The hospital, with 73.400 m² of surface and through which 7.300 people pass daily, now uses 90% renewable thermal energy instead of gas, avoiding the emission of about 8 tons of CO2 to the atmosphere daily.
