Tapping offshore wind energy to generate electricity is emerging as a clean and renewable source of affordable and reliable electricity. It has been on the top agenda of all wind energy producers and distributors worldwide since 2006. The filling of patent applications in the offshore wind energy field surged between 2006 and 2022. The patenting activity in offshore wind energy remained dominant in the field of floating foundations, erection of turbines, transportation equipment and mechanical transmission. Inventors have also shown interest in scaling up the combining offshore and electrolysis, thus opening doors for the production of green hydrogen.
