The TERA_RED project aims to generate technical scientific knowledge on very low temperature networks, also known as anergy, neutral or 5G networks, by applying the scientific method on a laboratory scale, both virtual and experimental, by comprehensively studying the various technologies involved in distribution, generation, storage, management and interaction with other higher temperature networks and cooling rings, in order to make a substantial leap forward in the knowledge available in their design, management and operation, enabling an improvement in the positioning of Spanish industry in a decarbonisation scenario, management and interaction with other higher temperature grids and cooling rings, in order to make a substantial leap in the knowledge available in their design, management and operation, enabling an improvement in the positioning of Spanish industry in a scenario of decarbonisation of the economy and electrification of energy consumption under an integrated conception of the energy system.
