| Sumario: | The objective of this work is to conduct a study of a hydrogen production plant, which uses the surplus of the electricity generated from the solar photovoltaic installation as a source to produce hydrogen, once the base demand to the industrial sector has been covered. Additionally, as secondary objectives, the available electrolysers on the market will be studied to determine which one might be the most appropriate for the studied case, the regulations related to hydrogen technologies and the potential impact of the plant deployment will be analyzed, and a Matlab code that simulates the hydrogen production plant will be developed and validated. Firstly, the considered area is studied to understand the terrain conditions and the feasibility of deploying the plant without causing any negative impact, as well as analyzing the current regulations that promote these technologies. It is successfully confirmed through the review of municipal regulations and Natura 2000 Plan that the chosen area, Puertollano, is suitable for carrying out the activity, and also from the Royal Decrees and European Directives, action plans and subsidies in favor of the use and development of these technologies are confirmed. Next, the corresponding calculations for the hourly production of photovoltaic energy as well as the hydrogen produced is done, being the basis to analyze the payback period, the general profits and the hydrogen production frequency. From these calculations, a complete reduction of electric consumption is obtained for the alternative considering 100% of the demand covered, that is, 2500 MWh, only requiring the action of the grid at those times when the renewable resource isn’t available, resulting in savings of €45.616, Similarly, the highest hydrogen production is achieved, specifically 9 tanks of 2.8 tons, translated into profits of €128.973,6; however, covering a higher demand and producing more hydrogen also involves larger disbursements, €574.692,00, despite they are recovered in 5 years. As mentioned, a plant model has been built using Matlab, since it allows combining different technologies in a modular way, providing flexibility for future studies. This model has been built, compared and validated with the results from the Spreadsheets, meeting the established objectives. Finally, through the different chapters in the study, the potential of Spain to exploit a renewable resource such as solar energy is highlighted, which empowers the energy transition and decarbonization. Furthermore, it also helps to create new job positions to be filled and a flow of money that leads to strenghtening the economy, which is considered as a succes in the study. |
