Methodology for analysis of thermal energy storage technologies towards a circular economy (MATCE) is a
multi-disciplinary coordinated project with three sub-projects: (sub-project 1) Universidad de Lleida,
(2) Universidad de Barcelona and (3) Universidad Rovira i Virgili. The project is aligned with the
Spanish Strategy for Science and Technology and Innovation 2013-2020 and the EU Energy strategy with its
contribution to the challenge safe, sustainable and clean energy with TES as a key technology.
Specifically, it contributes to the Spanish Strategy on Circular Economy, Circular Spain 2030 by
developing a specific methodology for the sustainability assessment and circular economy.
Today thermal energy storage (TES) has reached different levels of maturity concerning their
commercialization and application. Previous projects of the participating universities focused on the
improvement of materials, their characterization, the development of new materials and the design and
the evaluation of different applications for TES systems and barriers to their implementation. A new
challenge is presented by the Circular Economy strategies at European and national level. Circular
economy is based on the principle of closing the life cycle of goods, services, waste, materials, water,
and energy. Therefore, TES is included in this new circular economy approach of considering our actions,
as energy is part of the concept, but one step further is to consider circular economy principles when
developing TES systems or materials.
Therefore, the main objective of this project is to develop and validate a methodology to evaluate and
improve the sustainability of energy technologies integrating TES in order to come closer to a circular
economy and to apply this methodology with different case studies for industry and building
