HEATING AND COOLING POLYGENERATION POWER PLANT (HEATING AND COOLING DISTRICI) ST-4 OF THE SCIENCE AND TECHNOLOGY PARK OF CERDANYOLA DEL VALLÈS, BARCELONA (SPAIN)

 

Electrical and thermal power supplier of the complex, including the frist particle accelarator synchrotron in Spain and the south western of Europe the Alba Synchrotron.

 

This polygeneration plant will allow energy savings of 109,000 MW/hour each year and will reduce CO2 emissions by 7,500 tons per year, (21,000 T. upon completion of the four plants), what represent, compared to traditional energy systems, savings up to nearly 35% by using residual energy (heat generated by electrical motors) for the production of cold and hot water. Based on a design with increases energy efficiency and savings it relies on a wide variety of technologies:

 

> Cogeneration engines. 3 of 3.35 MW each.

 

> Absorption machines. 2 of 50 MW each.

 

> Chiller. 2 of 5 MW.

 

> Storage tanks. 2 of 5,000 m3.

 

> Boilers. 2 of 4 MW.

 

> Refrigerating towers.

 

> Gas Natural boiler.

 

The ST-4 has pioneering facilities at European level that have been subsidized by the European Union through the project Polycity, such as: a refrigeration machine by double-effect absorption only in Europe, which uses the heat generated by electric motors to cool water from the district cooling network; a thermal storage tank of large capacity, which allows the plant to operate at a steady pace for 24 hours a day; or an advanced energy management system that optimises plant efficiency.

* The system will also incorporate two renewable energy facilities on a trial basis at European level: a biomass gasification plant and a solar cooling plant.
