This study aims to perform a feasibility study on the DTU 10MW-RWT wind turbine blades constructed in the fossil-free high-strength steel 1300 MPa from SSAB. The acceptance criteria, on which the study is based, are taken from the DTU composite wind turbine model. A maximum weight of 41 000kg and a maximum tip displacement of 12.5 m are chosen. By fulfilling the acceptance criteria, the results of this study could contribute to a more sustainable future by decreasing the carbon dioxide emissions of wind turbine blades and improving their recycling options. To perform weight optimization the Finite Element Analyses software Abaqus and the optimization software Tosca Structure are used. The study is conducted based on Design for Six Sigma (DFSS) up until the design concept SG2. The study results in a preliminary design of the wind turbine blade constructed in SSAB Strenx 1300 and proofs that Tosca is a suitable software for performing weight optimization. The results show that it would be feasible to replace the wind turbine blades with SSAB Strenx 1300 MPa, but it will result in a weight increase for the current design. For further studies, it is recommended to consult with the stakeholders on how much weight increase of the blade is acceptable and study on how to modify the design of the steel wind turbine blade.
