| Project title | Transdisciplinary end-of-life analysis of wind energy plants for the development of technically-economically optimal post-use strategies (TransWind) |
| Project duration | 01.11.2020 – 31.10.2023 |
Of the approximately 30,000 wind turbine generators (WTGs) currently in operation in Germany, about half will reach the end of their service life in the next ten years. Continued operation would be unprofitable – for example, due to the expiry of 20-year EEG subsidies.
It is not yet clear what a technically and economically optimal post-use strategy for these WTGs could look like. Therefore, the research project TransWind pursues the overall goal of analyzing the end-of-life issue of wind turbines in Germany with the help of a transdisciplinary approach from different perspectives on micro and macro level in order to provide problem-specific decision support for the different actors from politics, wind industry as well as resource and recycling management in the selection of an optimal post-use strategy.
The joint project TransWind is coordinated by the Institut für Statik und Dynamik (ISD) of Leibniz University Hannover. The project partners include three further research institutions – including the Institut für Integrierte Produktion Hannover (IPH) gGmbH – and four companies.
The IPH sub-project is entitled "Development of technical and logistic deconstruction and repowering concepts and a GIS-based spatial planning analysis". This includes in particular the development of technical-logistical end-of-life concepts as well as support in spatial planning analysis and the development of cost models.
Publications about the project
For more than half of the approximately 30,000 wind turbines in Germany, the 20-year EEG funding will end in the next ten years. It is still unclear what the optimal technical and economic strategies for end-oflife utilization might look like. The BMWK joint project „TransWind“ aims to analyze the end-of-life issue on a micro- and macro-level in a transdisciplinary manner to support stakeholders from politics, the wind industry, and the resource and recycling sector in the selection of end-of-life strategies.
