The main purpose of this document is to gather the information necessary to understand the energetic picture in Tenerife as well as the current energy storage technologies, to explain why Hydrogen may be one of the main characters in the energetic transition plan conceived by the local Government. Hydrogen has several physics characteristics that makes it an appealing alternative for fossil fuels in mobility. Furthermore, although hydrogen is not present in its natural condition, it can be produced using electricity to be stored and used afterwards to obtain electricity again. This has attracted the attention of the whole scientific community since it can be potentially used as energetic vector or even energy storage technology. Finally, a simulation has been executed using the software EnergyPLAN and the data of energy consumes expected in the island in 2030 with the purpose of studying the viability of the target scenario raised by local institutions in order to fight against the climatic emergency. El objetivo principal de este documento es reunir la información necesaria para comprender el panorama energético en Tenerife, así como las tecnologías actuales de almacenamiento de energía, para explicar por qué el hidrógeno puede ser uno de los protagonistas del plan de transición energética concebido por el Gobierno local. El hidrógeno tiene varias características físicas que lo convierten en una alternativa atractiva para los combustibles fósiles en la movilidad. Además, aunque este elemento no está presente en la naturaleza en su estado natural, se puede producir utilizando electricidad para ser almacenado y utilizado posteriormente para su re-electrificación. Esto ha atraído la atención de toda la comunidad científica, ya que puede ser potencialmente utilizado como vector energético o incluso como una nueva tecnología de almacenamiento de energía. Por último, se ha ejecutado una simulación utilizando el programa EnergyPLAN y los datos de consumos esperados en la isla en 2030 con el propósito de estudiar la viabilidad del escenario objetivo planteado por las instituciones canarias para luchar frente a la emergencia climática.

Over time, the way of life of our society has been changing, giving way to an era in which sustainable development and care for the environment play a leading role. Every day there is more commitment to renewable energy and consumer technologies that are more respectful of the environment. In addition, the pace of life and the characteristics of our society have led us to depend on devices and tools that facilitate our daily tasks. Our country is one of the countries with the highest vehicle-to-person ratio in the world. Due to these circumstances, the need to make a change can be seen, and little by little the electric vehicle is having a greater presence in the market, covering this need without having to depend on fossil fuels. This project has been developed around the same idea. Cover a need such as powering electric vehicles at a particular level, such as alleviating this consumption by providing the system with a photovoltaic power plant. The building for which we have developed the project is located in Santa Cruz de Tenerife, in which a photovoltaic generator with a power of 33kW will be installed. The photovoltaic installation consists of 60 panels of 550 watts each, which will be located on the nonpassable roof of the building. This installation is proposed to reduce consumption in common areas as well as power charging points for electric vehicles in the garage of the building. In addition, 3 charging points located in 3 community parking spaces, located on the first floor of the garage, have been planned as a solution for users who currently have electric vehicles or in the near future. This project is a positive bet that can generate a good impact among the users of the building, providing solutions to possible needs that they may in the near future.

This project includes the design of an electrical, home automation, fire protection system, ventilation system and photovoltaic installation for a sport center. The building design shows a main floor and a rooftop. The first floor has its own electrical switchboard, which will provide users more comfort. The photovoltaic panels are located in the roof. The home automation installation aids users simplifying the normal tasks, providing them with all the amenities like intelligent lighting with motion sensors, flood detectors and fire alarms. In addition to this, the blinds will close automatically in case of heavy winds.

This project deals with the implementation features of a wind farm of 6,9 MW of installed power in the municipality of Santiago del Teide in the province of Santa Cruz de Tenerife. The first point that has been checked out is to find the most suitable location for the facilities. Trying to avoid protected natural areas and trying to introduce the facilities with the consent of the inhabitants. Moreover, trying to put the installation away from the city center as much as possible. As well as looking for their installation in land for agricultural use to not slow down urban development. Once the location has been chosen, the wind characteristics of the area have been studied and how the Enercon E-70 wind turbine of 2,3 MW with a tower height of 85m would behave in those wind conditions then this analysis of the wind conditions will reflect the orientation within the wind turbines will be installed. After this process, the calculations for adaptations to the grid and grounding of the switching facilities and the medium voltage subway line were carried out by selecting the medium voltage facilities to be implemented. Next, the necessary technical documents will be generated for the correct development of the project, including in this section the report, plans, annexes and specifications. Finally, the installation budget for this wind farm will be developed.

The objective of this project aims at designing the installations of the fire protection systems, lighting and low-voltage in order to expand the services currently presented by a sports complex already built. The client requests the construction of an annex building that will be dedicated to teaching use. In addition, there will be installed a tennis court and two paddle courts outside of the sports complex.

Finally, highlight the fact that different legal provisions have been applied to each area and a series of computer programs have been used to carry out this project such as:  AutoCAD  DIALux  CYPE  Microsoft Word

It is clear to see that, nowadays, that energetic transition is unstoppable. Canary Islands renewable energy potential is undeniable, due to its climatology and geographic situation. In the energetic storage field, hydrogen is emerging as the main future tecnology. The main purpose of this project is to outline the benefits of using energy storage through hydrogen, specifically studying Tenerife’s case. Currently, we can find different energy storage projects in Canary Islands, such as Gorona del Viento in El Hierro, or Chira-Soria in Gran Canaria, both being pumped hydro energy storage. However, Tenerife does not own any energy storage solution. For that reason, and also following the technological trend, hydrogen must be considered a relevant option to solve storage issues in Tenerife. In order to develop this analysis, several sources have been both consulted and studied, such as reports, analysis, reviews, papers, roadmaps, normatives, etc. All of these are available on the bibliography. Hoy en día, la transición energética es imparable. El potencial de las energías renovables en las Islas Canarias es innegable, debido a su climatología y situación geográfica. En el ámbito del almacenamiento de energía, el hidrógeno se está postulando como uno de las principales tecnologías del futuro. El principal objetivo de este proyecto es estudiar y remarcar los beneficios de usar el hidrógeno como herramienta de almacenamiento de energía, concretamente analizando el caso de la isla de Tenerife. Actualmente, podemos encontrar diferentes proyectos de almacenamiento de energía, como la Gorona del Viento en El Hierro o Chira-Soria en Gran Canaria, siendo ambas centrales hidroeléctricas reversibles. Sin embargo, la isla de Tenerife no cuenta con ningún sistema de almacenamiento de energía. Por esa razón, y siguiendo la tendencia tecnológica actual, el hidrógeno debe ser considerado como una posible solución a los problemas de almacenamiento de energía en Tenerife. Para poder desarrollar este análisis, se han consultado y estudiado diversas fuentes: informes, análisis, reviews, papers, hojas de ruta, normativas, etc. Todo ello está disponible en la sección de bibliografía.

La tesis "Intra-hour solar forecasting for photovoltaic systems integration in weak electric grids" estudia la problemática de la variabilidad del recurso solar en la integración de sistemas fotovoltaicos en redes eléctricas débiles, que es el principal obstáculo que enfrenta esta tecnología para un despliegue masivo. Por un lado, se desarrolla un sistema de predicción de energía fotovoltaica intra-horario basado en dos cámaras de cielo capaz de predecir las rampas de producción causadas por el efecto de las nubes. El sistema hace uso de técnicas de procesamiento de imágenes y deep learning para identificar las nubes y predecir cuando éstas afectaran a la producción de las plantas fotovoltaicas cercanas. Por otro lado, se evalúa el potencial fotovoltaico de las Islas Canarias haciendo uso de técnicas de Big Data. También se estudian los problemas de integración derivados de la inclusión de energía fotovoltaica en las redes eléctricas de distribución, proponiendo un algoritmo para la optimización del control de los inversores fotovoltaicos.

In this final project, a complete study was accomplished for a thermal solar installation and a photovoltaic solar installation, to reduce maintenance costs at the El Polvorín de Taco sports complex, located in the municipality of San Cristóbal de La Laguna. The study was based on the actual consumption data provided by the maintenance manager of complex. First, the solar thermal installation has been designed to adjust the temperature of both swimming pools and hot water. It has been designed in such way that the collectors are placed directly on the roof of the pool, adapting them to the already existing characteristics of inclination and orientation. It is concluded that 220 collectors of the Escosol FMAX 2.4 model has to be installed. Apart from the solar collectors, the other equipment involved in the installation that have also been designed are pipes, heat exchangers, expansion tank, heat accumulators, insulators and circulation pumps. Secondly, it was studied to add a photovoltaic solar installation taking advantage of the remaining space on the roof with the same characteristics of inclination and orientation. It was decided to install a total of 85 solar panels of 325 W by the manufacturer Talesun, with a 25 kW inverter by the manufacturer Fronius. Similarly, the other components that make up the installation have been dimensioned are wiring, earth connection, magnetothermic, differential and fuses. Finally, the necessary schemes have been carried out through plans or sketches with which it is intended to facilitate the understanding of how both technologies will be distributed and connected, both on the roof of the complex and in the engine room.

This Project describes the design, calculation and develop of two different wirings located in Tenerife South Airport, specifically in the down right corner of parking, one of the zones were usually rent a car companies operate. The location selected provides the ideal environmental conditions to generate energy due to irradiation level and amount of sunlight hours per day. One of them is a photovoltaic wiring that take the capacity to generate energy up to 12 kW to sell it to local electric distributor company at current market price. With this renewable energy system, airport manage company wins an input amount of money that helps to decrease the overall billing in concept of energetic consumption. Other is a charging point to provides energy for electric vehicles. This one is compounded about four chargers with 7,4 kW per each one. It is necessary that both wirings were separates according to new Spanish legislation. From economic point of view, the owner company also will receive payments from rent a car companies that use the chargers. That means an increasing of project viability due to energy consumption in points and photovoltaic generation will turn into money.
