Description du projet
De nouvelles technologies pour le déploiement d’énergies renouvelables dans les réseaux de chauffage et de refroidissement urbains
Le chauffage et le refroidissement résidentiels représentent jusqu’à 40 % de la consommation totale d’énergie. Des solutions innovantes pour le chauffage et le refroidissement urbains (CRU) sont donc indispensables pour un déploiement plus important des énergies renouvelables. Le projet RESTORE, financé par l’UE, développera une solution basée sur le stockage thermochimique de l’énergie (TCES) et la technologie du cycle organique de Rankine (COR). Le TCES permet de stocker et d’exploiter l’énorme quantité d’énergie qui est gaspillée, et la technologie COR adapte l’énergie fournie par différentes sources d’énergie renouvelable pour alimenter les systèmes de stockage et d’approvisionnement. En combinant les technologies TCES et COR, le projet permettra de développer une solution susceptible de lever les principaux obstacles au déploiement à grande échelle des énergies renouvelables et de la chaleur résiduelle du CRU.
Objectif
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.
