The European Union’s “2030 climate & energy framework” strategy (Link) sets the direction for European policies and objectives with the aim of reducing greenhouse gas emissions by 40% by 2030. This framework also calls for an increase of 32% in the share of renewable energies and a 32.5% improvement in energy efficiency. To contribute to the achievement of these objectives, the project proposes to advance in the decarbonization of energy-intensive industry through the implementation of thermal storage systems. Specifically, a systematized methodology will be developed that will allow the sizing and analysis of the technical-economic and environmental viability of low-impact thermal solutions based on thermal storage, as well as evaluating the suitability and advantages of implementing intelligent management strategies to optimize the energy, economic and environmental balance of the system. All this will be easily adaptable to use cases in different contexts of the building and industrial sector and to different company decarbonization strategies.
