The use of fibres in concrete is becoming more and more widespread. But can we go further? How about obtaining these fibres from recycling?

The main objective of the project is to define, obtain and extrude polypropylene fibres and perform different tests with these additives in concrete, so that they can improve the physical characteristics of the concrete, identify the advantages and disadvantages, as well as assess which fibres are the most suitable for REE (in form and dosage, or mixed with non-recycled fibres) for construction and to contribute to sustainable development.

Project for the collection of atmospheric water (condensation of water contained in the air) and the application of renewable energies.

Objective: To achieve self-supply of water for the electrical substations, thus avoiding dependence on external supplies or connection to municipal supply networks.

Project for the design of support and efficient node-based assembly system for Overhead Electricity Transmission Lines.

Objective: Compactness, Cost Reduction and Sustainability in overhead line supports.

In this project, a hybrid device has been developed and tested, capable of providing different flexibility services to the electricity system, especially in isolated systems such as the one in the Canary Islands. The device integrates a statcom, a lithium-ion battery and supercapacitors, optimally coordinated and managed by an advanced control system.

The PLATEA RENEWABLE project aims to provide a renewable power supply system for auxiliary services in a substation as an alternative to the use of a generator set.

Its main objective is to reduce environmental pollution by means of a hybrid generation system (photovoltaic+batteries) and to make the system portable for use in other locations.

The purpose of the project is to develop a hybrid storage system equipped with a grid-forming monitoring system. Therefore, firstly, the functional requirements that the system should provide were specified and PSCAD models were developed incorporating the controls developed. These models have been used to check, through simulations, the fulfilment of the functional requirements. Laboratory tests are currently being carried out to try to replicate the behaviour of a real electricity grid in order to study the behaviour of the device in response to different events. The project is being carried out in collaboration with HESStec and IBERDROLA.

The objective of the project is to provide a full-scale demonstration of the benefits and services that uncontrollable renewable energy plants in combination with dedicated storage systems could provide to the system. Therefore, a series of capabilities to be provided have been established by the generation and storage plant, specific models have been developed, and techno-economic studies have been carried out to determine the optimum size and degree of hybridisation (batteries + ultracapacitors) for the experimental plant in Barasoain, owned by Acciona, where the tests are being carried out. The last phase of the project is to carry out tests in a real environment where the slow and fast response capabilities will be tested. The testing of the former is currently nearing completion.

SafeDelimit is a hardware product for safe area delimiting at industrial environments. Thanks to its LiDAR capabilities, it is able, once programmed, to warn the technician or operator that he is entering an area of the installation in which, for safety reasons, he must not be. This solution won the DESPEGA intra-entrepreneurship program held in Redeia.

Based on technologies such as internet of things, artificial intelligence and data analytics, ASUMO aims to improve procedures and activities related to maintenance, engineering and construction areas in order to optimise and automate transport network infrastructure development processes, as well as in-service asset management.

The Virtual Synchronous Compensator (ViSynC) project is a crucial initiative on the path towards the ecological transition and the integration of renewable energy sources in the electricity system. Its relevance lies in the growing need to increase energy storage capacity in Spain to meet ambitious energy and climate targets. ViSynC addresses this challenge by developing a hybrid storage system combining lithium-ion batteries and ultracapacitors, managed in synchronous grid-forming mode, which allows maintaining grid stability and improving the integration of intermittent renewable energy sources.

ViSynC is an example of how Elewit is at the forefront of the energy transformation, leading the way towards a cleaner and more sustainable future. In this project we work with other companies, such as: Redeia, Red Eléctrica, Hesstec, CEN Solutions, S2 Grupo and CERE.

The ViSynC project is supported and funded by the following institutions:

The Ergonomic Grounding System Project (SERPAT) is an advanced solution for achieving the objectives of zero accidents and incidents in our activities. This project comprises a set of two devices designed to place and remove portable grounding safely and ergonomically, thus minimizing the inherent risks of this activity. Ignoring the implementation of a proper grounding process can have serious consequences in terms of safety for people, assets and the electrical system.

The objective of the project for the alternative design of transmission network pylons is to study new pylon designs that can reduce manufacturing and installation costs, as well as the associated carbon footprint thanks to the recyclability of the potential new materials that could be used. For this purpose, after a first technical-economic analysis, the second phase has been started, where mechanical, electrical and foundation calculations, constructability and maintainability throughout the useful life of the installation are established, taking into account criteria of recyclability of materials, circular economy, reduction of carbon footprint and health and safety of workers.

With the aim of seeking innovative and efficient solutions to continuously monitor SF6 gas by-products, Elewit launched the challenge "continuous monitoring systems for SF6 polluting by-products in high voltage equipment of the electricity transmission network". The objective was to find a solution that would not only detect insulation anomalies, but also provide information with which to characterize as accurately as possible the cause of the anomaly in a reliable and selective manner.

Once the winning proposal of the challenge, presented by the Nanophotonics Technology Center of the Polytechnic University of Valencia (UPV), was selected, a proof of concept was performed with three main objectives: to determine the efficiency of THz spectroscopy to detect the presence of SO2 and to define its threshold; to study the effect of the presence of SF6 on SO2 detection and to analyze the threshold of SO2 detection in a SF6 gas contaminated with a defined concentration of SO2.

The CICA Project, developed by Red Eléctrica, Elewit and SHEMAR, consists of the implementation of composite insulated cross arms for the deployment of electricity transmission lines. This solution offers multiple benefits, as by reducing the width of the overhead clearance (ROW) and the dimensions of the supports, their environmental and social impact is minimised.
