Abstract

This thesis discusses the development of a site selection tool for positioning Tidal Stream Generators (TSG) with respect to both the financial and environmental impact that the site selection process has. This is particularly important due to the current commercialisation of the tidal stream industry, which is presently transitioning from testing and refining device designs to fully functioning device deployment and even tidal stream arrays. Tidal power is billed as a green and renewable energy source that has the advantage of being reliable and predictable. However, current site selection techniques typically look purely at the feasibility and the financial elements of a project. The methodology proposed in this thesis combines the results from a typical Technical Feasibility Study (TFS) with a Life Cycle Assessment (LCA) to account for the Global Warming Potential (GWP) that occurs during the life cycle of a TSG. These results are combined with respect to a user-defined weighting system that will enable the user to weigh the importance of each of these elements. This results in the creation of a novel decision-making support tool for site selection of tidal devices, with both financial and environmental assessment aspects right at its core.
