摘要：Water scarcity is a threat for mankind and its symptoms have been aggravated by several factors such as climate change effects, increase in population and accelerated urbanization. Among the alternatives of water supply, the desalination has become one of the most sustainable solutions to provide freshwater. However, the process of desalination requires high quantities of energy and the use of renewable energy sources can make the technology affordable for regions characterized by fresh-water scarcity where the supply from electricity is not accessible. In this context, wind power can be singled out because of the constant innovations and progress of the wind power industry, which grows rapidly worldwide. This study aims to use patent applications for the technological forecasting of wind-powered desalination in order to analyse its innovation potential. China is the leader country in the technological development of this field, accounting for almost 80% of patent applications in the last 17 years. The patents analysis showed that innovations are being developed to combine the wind power, mainly, with Reverse Osmosis technology. This study also shows the immense potential of integrating of these two technologies as a strategic alternative for remote regions affected by a lack of freshwater and with no electricity access.
