Abstract
ABSTRACTThe search for suitable marine areas is a prerequisite at an early stage of any offshore renewable energy system project. This paper introduces a methodological framework for identifying the maritime areas the most appropriate to implement an offshore wind turbine farm in the Hong Kong bay. The framework is based on the combined use of Multi-Criteria Decision Analysis (MCDA) and Geographical Information Systems (GIS). At the first stage of the analysis, unsuitable areas for the deployment of an offshore wind turbine have been first identified. At the second stage of the analysis, eligible marine areas have been ranked using a MCDA and different scenarios. Finally, a cost analysis has been performed to refine the whole approach as well as a comparison to previous studies in the Hong Kong bay.
Highlights
Renewable energy is one of the greatest challenges for developing countries
The aim of this paper is to develop a decision-aided system whose objective is to estimate some suitable locations for offshore wind turbines in the Honk Kong bay by considering different levels of such constraints and combining Geographical Information Systems (GIS) with Multi-Criteria Decision Analysis (MCDA)
This is the reason why different zones are possible, but they are all in the same area, which is cohesive because whatever the method used, the similar requirements are taken into account. This applies at the exception of the Western zone, because all criteria but the wind were respected; it was a very suitable area according to the MCDA but it was not the most appropriate one
Summary
With an estimated population of 1.404 billion people, an important objective for China is to develop clean and sustainable ways to produce energy. Marine renewable energy like offshore wind turbines has become a subject of increasing interest in the recent years. The main principle of wind turbines is to capture wind strength and convert it into electricity. The objective of such installations is to be as productive as possible, while minimizing additional costs, as well as environmental and social impacts. An important issue before planning the development and implementation of an offshore wind turbine farm is to search for the most appropriate technologies and some potential sites for implementing them
