Monitoring scientific collaboration trends in wind energy components

This report presents a bibliometric analysis of scientific articles issued on blades and on offshore wind support structures. It uses the JRC-developed TIM software for data analysis and visualisation, drawing on text mining and network analysis to count publication activity levels and identify collaboration patterns between entities. Our bibliometric searches detected increasing densification in the co-publication networks mapped by TIM for blades and on offshore support structures. This indicated that scientific publication activity could be intensifying, and this was confirmed by experts and by literature on wind energy. Both provided evidence of growth in these two research fields, and of intensified collaboration among partners – following the wind-energy industry orientation towards larger blade designs and innovative offshore support structures. The recent EC Communication on a renewed European Agenda for Research and Innovation points out that Europe is relatively strong in adding or sustaining value for existing products, services and processes, known as incremental innovation. But Europe needs to do better at generating disruptive and breakthrough innovations. Thus, the agenda encourages cooperation between research teams across countries and disciplines, supporting them to make breakthrough discoveries. Also countries outside the EU have put policies in place (e.g. China's 12th Five Year Plan) explicitly focussing on technology innovation in the sector of onshore and offshore wind. Within this context, this analysis uses the JRC's Tools for Innovation Monitoring (TIM) software developed by the JRC to retrieve bibliometric data on blades (a component more benefitting from incremental innovations) and offshore wind support structures (a relatively new research field in which disruptive innovations like floating power plants might become breakthrough innovations) to - measure the publication and collaboration activity, - identify leading organisations and new entrants, - identify the main areas of publications of the leading players and - identify the leading countries and country collaboration patterns. The bibliometric results obtained are then contrasted with data for research funding on wind energy from the Horizon 2020 Research and Innovation programme, to analyse the thematic focus of publication and funding activity. Results are also complemented with recent information from the wind industry and research news on the latest developments in the investigated areas. Thus, this study can support policies aiming for prioritisation and alignment of European research efforts within the wind energy topic.
