While steel towers, concrete foundations, and copper cables are comparatively easy to recycle, rotor blades are much more complex and are made of different materials, making them significantly more difficult to recycle. The aim of our #research is to ensure high-quality recycling.   💡 Find out more about the opportunities and challenges of recycling rotor blades and our research projects in the blog article by our colleague Niels Ludwig 👉 https://lnkd.in/ecD6x3ma   #windenergy Photo: © Fraunhofer IWES

📃𝗡𝗲𝘄 𝗽𝗮𝗽𝗲𝗿 𝗼𝗻𝗹𝗶𝗻𝗲: "𝗡𝘂𝗺𝗲𝗿𝗶𝗰𝗮𝗹 𝗦𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗥𝗶𝗻𝗴 𝗖𝗿𝗲𝗲𝗽 𝗼𝗻 𝗮 𝗪𝗶𝗻𝗱 𝗧𝘂𝗿𝗯𝗶𝗻𝗲 𝗠𝗮𝗶𝗻 𝗦𝗵𝗮𝗳𝘁" Have a look at the paper written by our colleagues Peter Große and Hans Kyling. This paper presents an advanced finite element method (FEM) approach for #simulating ring creep in the main bearing assembly of wind turbines. The model enhances previous #research by incorporating the stiffness of the surrounding structure, enabling more realistic predictions of the ring migration effect. The research builds on findings from the "BeBen XXL" project, which revealed the occurrence of bearing creep on a wind turbine's main shaft. Earlier simulations had limitations, which are now addressed by a high-fidelity FEM model capable of simulating ring creep under realistic conditions. The developed "full model" accounts for the stiffness of all load-bearing components in the #windturbine drive train and employs a submodeling technique to accurately simulate movements and forces. This allows for a precise representation of ring creep. To the paper 👉 https://lnkd.in/eizskEzc #windenergy #WeKnowHow 

🌏𝗩𝗶𝘀𝗶𝘁 𝘁𝗼 𝗦𝗼𝘂𝘁𝗵 𝗞𝗼𝗿𝗲𝗮 Germany and South Korea are facing similar technical challenges: The demand of #greenhydrogen exceeds domestic production capacities, so both will have to rely on imports. Our colleague Simon Kühner has visited the city of Gwangyang together with colleagues from the Fraunhofer Innovation Platform Hydrogen Energy at Kentech. In Gwangyang, 35 million tons steel are produced per year. After a tea ceremony with the mayor, possibilities of a #hydrogen city were discussed with representatives of the council and the city administration. On the visit of the Hyosung Chonam Liquid Hydrogen filling station, Simon gave an interview.

On 19 March, we had our mid-term review meeting in the #ICON #NEMO project together with colleagues from France Énergies Marines and Fraunhofer-Institut für Windenergiesysteme. Thanks to Eric Dupont from EDF for hosting us at #EDFLab in Chatou, and to our project advisory group for the in-depth discussions - in particular Florent Guinot for BP, Julien HAIZE for TotalEnergies, Eric Dupont, and online Sylvio Freitas (Vattenfall) and Zachary Parker (RWE). #NEMO - for: "New methods for turbulence measurements and models in offshore wind" - is a French-German collaborative project with the two sub-projects DRACCAR-NEMO (https://lnkd.in/ebvgMa9M) and ICON-NEMO (https://lnkd.in/evSAcDQx). We have 18 months left in the project during which we will work together on solutions for assessing wind turbulence in offshore wind - using fixed, floating and dual scanning lidar measurements, WRF mesoscale simulations and LES.
