Abstract(s)
O crescimento do consumo mundial de energia levou a que o mundo procurasse novas formas de energia renovável de forma a moderar a nossa dependência em combustíveis fósseis que tanto prejudica o meio ambiente. A previsibilidade e a imaturidade tecnológica que permite a exploração de um mercado em desenvolvimento da energia das marés faz com que esta seja uma das soluções renováveis promissoras para substituir e diversificar as fontes de energia. O objetivo principal deste trabalho é avaliar a energia passível de ser extraída da Ria de Aveiro através de aproveitamentos de maré. Tal foi atingido através da aplicação de um modelo desenvolvido no programa Delft3D capaz de reproduzir a hidrodinâmica da laguna. Através do software, foram corridas simulações com o intuito de identificar as melhores zonas de exploração de energia potencial e de energia cinética. Para os locais de maior interesse, foram calculadas potências e energias anuais para ambas as tecnologias de aproveitamento de maré. Através da comparação dos resultados deste trabalho com literatura, concluiu-se que o potencial energético da Ria de Aveiro é considerável e que poderá ser interessante, num futuro próximo, ponderar albergar algum tipo de aproveitamento de maré.
The growth in world energy consumption has led the world to search for new forms of renewable energy in order to moderate our dependence on fossil fuels that damages the environment so much. The predictability and technological immaturity that allows the exploration of a developing market for tidal energy makes of it a very promising renewable solution to replace and diversify energy sources. The main objective of this work is to evaluate the energy that can be extracted from the Ria de Aveiro through tidal exploitation. This was achieved through the application of a model developed in the Delft3D software, capable of reproducing the hydrodynamics of the lagoon. Through the software, simulations were run in order to identify the best areas of potential energy exploration and kinetic energy exploration. For the places of greatest interest, power and annual energy were calculated for both tide exploitation technologies. By comparing the results of this work with literature, it was concluded that the energy potential of the Ria de Aveiro is considerable and, in the near future, it may be interesting to consider the accommodation of some type of tidal exploitation.
