On April 7, 2022, we were happy to have Per Lindström Lussi from Linnaeus University among our lineup of speakers at the 5th Wind & Drivetrain Conference 2022.
Per LINDSTRÖM LUSSI is a Sámi Mariner (Marine & Welding Engineer) who graduated with a Ph.D. in Production Technology (2015) from University West in Trollhättan, Sweden; a Licentiate of Naval Architecture and Ocean Engineering (2005) from Chalmers University and a B.Sc. in Marine Engineering (1991) from Linnaeus University.
Since his completed active sea service as Chief Engineer Officer in the Swedish Merchant Navy, Per Lindström has concentrated his professional career on specialty welding operations in the field of marine structures, nuclear reactors, boilers, and pressurized equipment. Since March 1, 2017, he has been a Senior Lecturer in Marine Technology at Linnaeus University.
Per Lindström is a steering committee member of Linnaeus Knowledge Environment: Advanced materials; chairman of the Swedish Welding Commission's workgroup AG41 'Welding metallurgy and Fracture avoidance'; and since 2005, Sweden's delegate to the IIW working unit C -X 'Structural performances of welded joints — Fracture avoidance'.
The title of his presentation is "Fossil Free High Strength Steel Wind Turbine Blades — Concept Feasibility Study"
Abstract:
There is a need for environmentally friendly and recyclable light-weight wind turbine blades. Light-weight wind turbine blades are currently constructed in Glass Fiber-reinforced Plastics (GRP) and Carbon Fibre reinforced Plastic (CRP) composite materials. Combinations that don’t decompose into nontoxic organic materials and/or minerals during the foreseeable future when buried, therefore, create a substantial negative impact on the environment.
By 2023, ca. 14 000 wind turbine blades from first-generation wind turbine farms will be decommissioned in Europe. Due to financial aspects, the recycling of GRP and CRP are believed to be performed by large landfills. With increasing wind power farms, the number of GRP and CRP wind turbine blade landfills will also increase.
Therefore, Linnaeus University Welding Mechanics Laboratory, LNU WML, in Växjö, Sweden, is performing a feasibility study of a novel fossil-free high, strength steel wind turbine blade concept. This study explores the possibilities of SSAB Strenx and SANDVIK steel grades by the well-established scientific engineering method ‘Systems Engineering’ and the Dassault Systèmes Finite Element Analyses (FEA) solver Abaqus in combination with its optimization software Tosca.
All in all, for the sake of manufacturing wind turbine blades by:
I. Recyclable material
II. Reduced cost by about 50% compared to GRP and/or CRP
III. Less negative environmental impact compared to GRP and/or CRP
Preliminary results indicate more than 10% blade weight reduction by using Swedish fossil-free high-strength steel instead of GRP and/or CRP.
