IRENA – Offshore Wind Energy Report, 2023

The IRENA Offshore Wind Energy Report offers a comprehensive analysis of patent filings in the offshore wind energy sector from 2002 to 2022. The report emphasizes the significance of offshore wind in tackling climate change and achieving sustainable energy goals. The study examines around 17,000 patents from the European Patent Office's database, covering various aspects of offshore wind technology. The data indicates a surge in global patent filings between 2006 and 2012, followed by a period of stagnation and then a resurgence in activity from 2017 onwards. The analysis highlights the dominance of European countries, particularly Germany and Denmark, in terms of filed International Patent Families. Notably, the United States, China, and Japan also demonstrate considerable patent activity in the offshore wind sector. The report identifies areas with high levels of invention activity, including floating foundations, transportation equipment, and the integration of offshore wind with green hydrogen production. The interest in floating foundations is driven by the potential to install turbines in deeper waters with greater wind resources. Additionally, the sector is exploring alternative tower and blade designs to reduce steel consumption and enhance sustainability. In conclusion, the report provides valuable insights into the global offshore wind energy landscape, emphasizing technological advancements and market trends. It underscores the crucial role of innovation in addressing challenges and driving the growth of the offshore wind industry.
