Assessment of potential for Aquifer Thermal Energy Storage Systems for Spain

Aquifer Thermal Energy Storage (ATES) Systems is a technology to sustainably and economically provide space heating cooling. However, it cannot be applied everywhere because successful application depends on the presence of suitable aquifer favorable climatic conditions. Despite some operational ATES systems, Spanish market immature, there are no regulations or guidelines developed. To foster adoption in Spain, this paper introduces potential study considering resource potential, technical, economic, environmental aspects. The GIS-based approach focused geographical identification assessment for This allows distinguish those areas considered more systems residential tertiary sector. results show where Spain energy GHG savings with can found. 38% aquifers 63% large urban located such areas. Also, 50% population lives sector seems based reach up 91% 68% respectively, derived from use ATES.
