HERCULES introduces an innovative approach to thermal storage of surplus renewable energy through a hybrid thermochemical/sensible thermal storage concept, applied with the help of porous media made of refractory redox metal oxides and electric heating elements. Specific redox oxides are capable of undergoing reversible reduction/oxidation reactions when heated/cooled in direct contact with air, accompanied by endothermic/exothermic thermal effects, respectively. The heating elements use surplus/low-cost renewable electricity (e.g., from photovoltaic, wind, or other renewable sources) to charge the porous storage block made of metal oxide by heating it to a level above the reduction onset temperature of the metal oxide (i.e., the energy storage/charging stage).

Therefore, energy is stored in the porous oxide structure both sensibly and thermo chemically through the endothermic reduction reaction. Later (i.e., on demand), the fully charged system can transfer its energy to a controlled airflow passing through the porous oxide block, initiating the exothermic oxidation of the reduced metal oxide. During this step, a stream of hot air is generated, which can be used to provide usable heat for industrial processes.

These storage systems based on redox oxide materials not only have a much higher energy storage density than conventional sensible types, but they also offer a high discharge temperature range (> 500 ºC), do not require gas storage, and greatly simplify the overall system design and operation.

DESOLINATION es un proyecto de colaboración cuyo objetivo es descarbonizar el proceso de desalinización en las regiones áridas demostrando en un entorno real el acoplamiento eficaz de una planta CSP a un sistema de desalinización por ósmosis directa. Para lograrlo, se utilizará la ósmosis directa (presión osmótica) para inducir un flujo de agua de mar hacia una solución de extracción. En su camino, el agua atravesará una membrana que sólo dejará pasar el agua dulce, pero bloqueará la sal. Utilizando el calor residual de la planta CSP, la solución diluida se calentará hasta que el agua dulce pueda recuperarse a través de una segunda membrana.

GENERDIS is an industrial research project focused on investigating new photovoltaic technologies, storage, and energy management for distributed generation. These technological capabilities will be directed towards the digitalization, management, and optimization of resources within energy communities. The project is based on three main pillars:

(1) Optimized management of decentralized energy resources, both for the energy community and the electrical system as a whole, through optimization algorithms and Artificial Intelligence-based systems.

(2) Research into innovative storage technologies for generated energy, including centralized storage at the community level and its digitalization.

(3) Investigation of new materials, methods for maximizing solar resource utilization, and integration into available building surfaces.

The objective of this project has been the development of a system capable of automating the early detection of leaks in heat collector pipes of concentrated solar power installations, redundantly and through the use of artificial intelligence technologies applied to image recognition, as well as IoT technologies.

This solution involves automating the detection by incorporating a set of elements into the installations that monitor the sensitive components of the entire plant, along with a system capable of processing the generated images and providing real-time and highly reliable alerts of leak production from the very moment they occur.

To carry out this project, we have worked with artificial intelligence technologies, specifically machine learning and deep learning, in combination with IoT technologies that have allowed us to collect both optical element images and information from sensors in the installations, which will act as redundancies or corroborators. Additionally, cloud computing technologies have been utilized for system training tasks. We have successfully connected the information acquisition systems (images and other sensors) with IoT technologies and created training systems in the cloud.

This project has been subsidized by Red.es through the 2020 Call for Grants on technological development based on artificial intelligence and other digital enabling technologies, within the framework of the strategic action on digital economy and society of the State R&D&i Program aimed at addressing societal challenges and the State R&D&i Business Leadership Program (C007/20-ED).

The BALITH project focuses on developing a new organic REDOX flow battery suitable for operating temperatures up to 80°C. Conventional REDOX flow batteries are designed to operate at temperatures up to 40°C; however, the battery generates heat and requires a cooling system to prevent electrolyte degradation or battery malfunction. This cooling consumes energy and consequently reduces the overall efficiency of the battery. Thus, this new technology will allow operation at temperatures of up to 80°C without the need for cooling.

Offshore wind energy has a number of advantages over terrestrial technologies as it is possible to find locations with greater wind resource. In addition, offshore conditions allow the installation of larger and more powerful wind turbines. However, it is still necessary to continue reducing costs in manufacturing, installation, operation and maintenance.

Regarding O&M operations, the marine environment entails more severe conditions during its useful life, which is why WATEREYE sets corrosion as a key point for cost reduction in offshore wind farms as these costs can represent up to 30% of the LCOE (in 2030 an estimated LCOE of 70 €/MWh). In addition, other risks associated with corrosion are structural failures and downtime due to repairs.

The main objective of the WATEREYE Project is Maintenance-Predictive, i.e. to obtain the necessary tools for the detection and prediction of future failures. This project basically follows 3 main lines.

1. Development of a monitoring system capable of remotely calculating the level of corrosion in specific areas.
2. Development of algorithms for the control of wind turbines as well as the global control of the whole plant.
3. Development of high precision ultrasound sensors to measure corrosion in real time. As well as a robust "wireless" communication system specially designed for marine conditions. In addition, a drone will be designed to monitor the surfaces from inside the tower.

These proposals will be validated by means of tests and simulations that allow to verify the functionality and efficiency of the developed systems.

Floating offshore wind is still a nascent technology and its LCOE is substantially higher than onshore and bottom-fixed offshore wind, and thus requires to be drastically reduced. The COREWIND project aims to achieve significant cost reductions and enhance performance of floating wind technology through the research and optimization of mooring and anchoring systems and dynamic cables. These enhancements arisen within the project will be validated by means of simulations and experimental testing both in the wave basin tanks and the wind tunnel by taking as reference two concrete-based floater concepts (semi-submersible and spar) supporting large wind turbines (15 MW), installed at water depths greater than 40 m and 90 m for the semi-submersible and spar concept, respectively. It is aimed that the resulting recommendations will facilitate the cost-competitiveness of floating offshore wind energy, reducing risks and uncertainties and contributing to lower LCOE estimates. COREWIND aims to strength the European Leadership on wind power technology (and specially floating). To do so, the project consortium has been designed to ensure proper collaboration between all

Biomass solar micro generator for residual use.

The general aim of this project resides in the development of a compact micro-trigeneration system using biomass waste from tree pruning and agroindustrial waste as its principal fuel, hybridized with concentration solar power technology for distributed generation of heat and cold electrical energy. The system should be compact, modular and scalable within the range of micro and small power generation in such a way that all of its components can be contained in one or various containers as easily interconnecting modules.

The developments undertaken in this project can be implemented in any part of the world with access to agricultural waste and biomass. It is especially interesting in situations where there exists an intense seasonal demand for energy and in isolated outposts where the distribution networks are inadequate and the transport of other fuel such as gas or diesel creates a difficult logistical problem. It is here where distributed power generation is most efficient

The principal clients for the system will be the food processing industry located in remotes places and with difficult access to electricity (which has a negative impact on the prices of their products). The waste products from these industries will be the raw materials that can be used for power production.

This project is being carried out by the consortium led by COBRA with the participation of GAMMA SOLUTIONS, MARLE, AUSCULTIA y GESTIONA GLOBAL.

The Grand Solar project was born from the desire to make a quantitative leap forward in the technology applied to thermal solar plants with concentration towers. The objective of the project was to develop new technologies to perfect heliostat (sun tracker) specifications, in concentration tower thermal solar plants. The final aim is to create models that will lead to the development of power plants with a capacity of 100 MW or more.

The general objectives were:Research and development into heliostats with “0” spacing and a greater net surface area.

To increase the distance from the receiving tower to 1500 meters in contrast to the 800 meters achieved with the older technology.

The development of a series of characterization tools for heliostats in relation to the surface area and the possible the deformations produced by wind and gravity as well as the distance from the target tower.

Bearing in mind the peculiarities of the new development in terms of size, wind resistance and the effects of gravity and the distance to the target, it was necessary to have a complete characterization that ensured correct functioning. The proposed characterization system was based on a ray tracing program that allow the optimization of each heliostat, by taking as reference chosen heliostats and their position in relation to the tower and in the design phase through the optimum configuration for collecting of energy. COBRA has great experience in the installation of electric power plants and in particular in solar energy and as such led in the aspects of installation of the large size heliostats, those with a surface area of 2 by 1.6 m, each with its own edge and reflection characteristics.

New solutions for floating platforms and innovative technology associated with the energy evacuation and network integration for floating maritime wind farms.

FLOCAN TO GRID emerges as a strategy for the investigation and development of the technical and economic viability of two floating technologies at full scale in addition to that of the necessary energy evacuation infrastructure and subsequent integration in the power grid in typical operating conditions along with the tools needed to define the operational logistics associated with the life cycle of an infrastructure located in an adverse environment.

The technologies to be developed in the project are robust, efficient, floating solutions for turbines from 5MW to 8MW for deeper water usage and aimed at mass production. These will minimize the operations in deep sea environments with human, economic and environmental risks. In addition, by having two solutions, all the necessary elements for the general power evacuation from an offshore farm will be studied, differing from other ad-hoc defined evacuation solutions for a single prototype. In this way, all concepts will be integrated in the global development for operations associated with multi-megawatt wind production in deep water as a new sustainable and renewable resource.

[wpv-autop]The results of this project are aimed at developing the first experimental marine wind farm, called FLOCAN5, located in the Canary Islands. The innovation associated with the project will be technically and economically viable in the medium term, with the aim of achieving market acceptance and of fostering the creation of highly valuable knowledge and new competitive industrial capacities associated with the priorities of  Objective Horizon 2020.

The consortium led by COBRA Instalaciones y Servicios,  provides a response to the needs of the sector through this strategic positioning in this new industry.

The objectives of the project for commercial solar power plants are the following:

• The development of specific point sensors (optical and/or thermal) for the precise and robust measurement of concentrated solar radiation in the conditions expected in commercial plants.
• The combination of specific measurement systems (sensors, thermocouples) with other systems capable of global measurements or estimations over large areas (cameras VIS and IR).
• Integrating these systems into the design of solar receivers in tower plants.
• Analysis and evaluation of the integration of the measurement system in the plants control system.

The development of this technology will provide COBRA with a significant commercial advantage in the area of thermal solar energy not only through the durability of the key plant components (solar receivers) but also through their efficiency, which will bring about a reduction in energy production costs and will make a positive contribution to the competitiveness of the company at an international level.

Further responsibilities included: 1) The development of simulation tools for the creation of an electricity production profile aimed at assessing the commercial competitiveness of the energy storage technologies. 2) Plans for commercialization. 3) Business innovation strategies. 4) Contribution to the development of the normative. 5) Creating business models for the regional control centers and new plans for the development of hybrids.

This project was born from the need to acquire better information about the independent management systems that exist in cities within different public services such as street lighting, district heating and electric vehicles etc. in order to achieve advanced coordinated energy saving strategies, as well as providing new business models. In order to obtain this advanced integrated system, a support system was created to help in the decision making that improves urban energy efficiency (Open Trustworthy Energy Service Platform), permitting a reduction in cost and guaranteeing the quality of services (QOS).

COBRA 's role in this project was to contribute with their experience in renewable energy generation and the interaction with the Spanish TSO in the development of the aforementioned platform.
