Analysis of potential and integration opportunities for DHC networks
The development of concentrated solar power (CSP) technology has received a boost over recent years by the increase in electricity generation plants. Despite this, Spain currently has very few CSP facilities for thermal applications, largely designed to cover the demand for heat in industrial processes or for the temperature control of buildings. However their application for thermal use has a huge development potential in the country given that some regions have a very high availability of direct solar irradiation. The Institute for Energy Diversification and Saving (IDAE) has undertaken a technical-economic study on the incorporation of CSP into district heating & cooling (DHC) networks, using a reference network situated in Jaén. The results obtained conclude that the incorporation of CSP installations into DHC networks is a viable and attractive alternative that is both technically and economic competitive.
According to the census undertaken by the Spanish Association of DHC Networks (ADHAC), there are currently around 270 DHC networks in Spain with a total combined installed capacity of 1,139 MW for heating and cooling. Out of the existing DHC installations, approximately 30% use renewable energy (mainly biomass) and only one incorporates solar power. This is the DHC network at the Balearic Science andRead more…
