About Us

This European project facilitates the development of innovative, thermal energy storage technologies that can easily be integrated into buildings to increase their energy efficiency and grid flexibility.

A consortium of 20 organisations from across europe is lead by Veolia Spain and brings together leaders in thermal energy storage research, innovative technology development and thermal storage manufacturing companies to deliver cutting edge thermal energy storage at three demonstration sites from northern and southern europe.  ThumbsUp aims to overcome the limitations of existing building-integrated technologies by increasing energy density and reducing the intensity factors of capital investment in this sector. The project will promote complementary digital innovations aimed at simulating, optimising and maximising the technical, operational and economic benefits of the proposed storage solutions.

Project Overview

The ThumbsUp project aims to develop and demonstrate thermal energy storage (TES) at daily (based on PCM) and weekly level (based on TCM sorption technology) solutions to be easily integrate in EU buildings (both connected and not-connected to DHN) to increase their energy efficiency as well as to exploit power-to-heat approaches also to make EU Buildings as grid flexibility actors. The ambition of ThumbsUp is therefore to deeply demonstrate this technology in three demo sites in different EU climates and energy market contexts, also to assess ThumbsUp replication potential in further two replication sites. Via its demonstration and replication campaign, ThumbsUp promotes the role of TES as key enabling technologies to optimise thermal comfort and energy efficiency in buildings as well as to promote Power-to-heat as facilitator of RES grid integration in a sector coupling approach.
