The THESILO project is a pilot initiative exploring the conversion of old grain silos into thermal batteries for renewable energy storage. These structures, which are currently disused, are strategically located, have a large capacity and feature highly robust concrete structures, making them ideal candidates for reuse in thermal storage systems. Their transformation will enable greater integration of intermittent renewable sources, contributing to the stability of the electricity grid and the decarbonisation of the energy system.
The project is structured around four main areas: (1) selection and adaptation of silos, assessing their structure and insulation and applying digitalisation tools; (2) optimisation of the storage medium, exploring options for recycled and efficient materials for thermal energy storage; (3) design and integration of systems, including Power-to-Heat, heat exchangers and heat transfer fluids; and (4) feasibility assessment, analysing the model’s sustainability, legal impact and replicability. THESILO drives the revitalisation of rural areas, promoting investment in sustainable infrastructure, job creation and the transition to a low-carbon economy. Its implementation in the EUROACE region strengthens these regions’ competitiveness in energy innovation, positioning them as leaders in sustainable thermal storage solutions.
