Desenvolvimento e otimização de protótipo para recuperação da energia das ondas

Abstract

A crescente necessidade de energia a nível mundial implica uma inovação constante de dispositivos de captação de energia a partir de fontes renováveis, visto que é imperativo reduzir o consumo de combustíveis fosseis. O aproveitamento da energia das ondas apresenta-se como um sector ainda pouco explorado, ou por falhas confirmadas dos dispositivos desenvolvidos ou pela falta de validação experimental dos testados até então, levando a um maior investimento nos estudos desta fonte renovável de elevadíssimo potencial. O facto de Portugal dispor de uma vasta área oceânica, torna-o num país ideal para o desenvolvimento destes tipos de dispositivos. Esta dissertação apresenta-se como uma continuação das dissertações anteriores realizadas na Universidade de Aveiro. O principal objetivo é a continuação do desenvolvimento de um mecanismo de Power Take-Off com vista à elaboração de um protótipo para recuperação de energia potencial das ondas. Foi realizada uma análise do conjunto e de cada peça individual do conceito estudado até então, de forma a acrescentar melhorias ao dispositivo e a otimizar todo o sistema para aumentar a eficiência de conversão de energia. Finalizou-se com sucesso a fase de construção do protótipo funcional à escala, não se tendo atingido, contudo, o objetivo de realizar testes laboratoriais. Futuramente estes testes poderão ser realizados e, assim, será possível confirmar o potencial de geração de energia do dispositivo.

The growing need for energy worldwide implies a constant innovation of devices capable of capturing energy from renewable sources, since it is imperative to reduce the consumption of fossil fuel. The use of wave energy presents itself as a sector that has yet to be explored, either due to the confirmed shortcomings of the devices developed or the lack of experimental validation of those tested so far, leading to greater investment in studies of this renewable source of extremely high potential. The fact that Portugal has a vast ocean area makes it an ideal country for developing these types of devices. This dissertation is a continuation to previous dissertations carried out at the University of Aveiro. The main goal is to continue the development of a Power Take-Off mechanism with the focus on creating a prototype for recovering potential wave energy. An analysis was made of the whole and each individual part of the concept studied so far, in order to add improvements to the device and optimise the whole system to increase energy conversion efficiency. The construction phase of the functional scale prototype was successfully finalised, however the goal of testing the device was not achieved. It can be carried out in the future to confirm the device's energy generation potential.
