Research on tractor technologies as a pathway to decarbonisation through renewable hybrid energy grids of the future


The TERA_RED project aims to generate technical scientific knowledge on very low temperature networks. These networks, also called anergy, neutral or 5G networks, have been studied through the application of the scientific method on a laboratory scale, both virtual and experimental. In addition, the various technologies involved in distribution, generation, storage, management and interaction with other higher temperature grids and cooling rings, as well as the economics and electrification of energy consumption under an integrated conception of the energy system, have been studied in an integrated manner. All with the aim of making a substantial leap in the knowledge available in its design, management and operation, it has enabled an improvement in the positioning of Spanish industry in a scenario of decarbonisation.



    • Ability to design and manage low and very low temperature grids as a strategy to decarbonise conventional thermal grids by reducing dependence on gas.
    • New functional structures of geothermal systems and the analysis of the benefits of the integration of heat pumps on the structure of energy grids powered by renewable electricity will be investigated in view of the growing trend towards domestic photovoltaic self-consumption.
    • Independent experimental evaluations to obtain optimal data, from which the results will be used for the hybrid energy networks of the future to select the optimal system(s) for each particular case and to know their capacities, response and evolution over time.
    • Energy exchange between different types of grids combined with temperature rise systems or distributed control of substations, facilitating greater flexibility of the systems allowing increased use of renewable energy. The influence of each energy flow and boundary conditions on the overall structures of energy networks will be quantified, providing integrated solutions that enable optimised management of energy networks.
    • It will address research into the key aspects that influence and condition this joint management and operation, considering different types of interconnected storage, generation and demand forecasting, as well as their flexibility.
