Descripción del proyecto
Nuevas tecnologías para la implantación de energías renovables en redes de calefacción y refrigeración urbanas
La calefacción y la refrigeración en el sector residencial son responsables de hasta el 40 % del uso total de energía. Por lo tanto, se necesitan soluciones innovadoras para la calefacción y refrigeración urbanas (DHC, por sus siglas en inglés) para una mayor implantación de la energía renovable. El proyecto RESTORE, financiado con fondos europeos, desarrollará una solución basada en la tecnología del almacenamiento termoquímico de energía y la tecnología del ciclo de Rankine orgánico. La primera tecnología permite almacenar y aprovechar la enorme cantidad de energía que se desperdicia, mientras que la segunda adapta la energía de diferentes fuentes de energía renovable para alimentar los sistemas de almacenamiento y suministro. El equipo del proyecto combinará estas dos tecnologías para desarrollar una solución que pueda abordar los principales obstáculos para la implantación generalizada de la energía renovable y el calor residual en la red de DHC.
Objetivo
RESTORE proposes a radically innovative solution for DHC, based on the combination of two key innovative technologies (TCES+ORC), that allows integrating a wide variety of renewable technologies combined with competitive seasonal storage in DHC networks, allowing them to be 100% renewable to radically improve their environmental sustainability.
The first technology the project aims to develop is an innovative thermal energy storage system based on Thermo-chemical reactions, the Thermo-Chemical Energy Storage (TCES), that provides daily and seasonal competitive energy storage due to its high energy density, very low energy losses and its low-cost. The system represents a key development due to the fact that it allows harnessing the enormous amount of energy that is normally wasted due to the mismatch between energy demand (loads) and energy generation (related to the availability of the renewable resource or waste heat), mainly occurring between seasons. In addition, the project aims to develop a second technology that is based on Heat Pump and ORC and is combined with the TCES system. This second technology adapts the energy provided by different renewable technologies to feed the storage system, thus a wide variety of renewable technologies as well as waste heat can be integrated into the whole system to finally supply the energy demand under the specific conditions laid down by each DHC.
This radically innovative solution would tackle the main barriers for a wide deployment of renewable energy technologies and waste heat in the existing and future DHC networks. The projects consider the experimental validation of the RESTORE concept and also the demonstration of the concept replicability potential, adapting and optimizing the proposed solution to different real sites (different network conditions and local particularities as the available renewable technologies/waste heat) spread over the EU, and quantifying its potential benefits via virtual use-cases.
