How accurate are wind measurements from dual-Doppler scanning lidar systems? And what is their potential for offshore wind energy? Fraunhofer IWES is investigating these questions together with Oldbaum Services Ltd and TotalEnergies through two concurrent measurement campaigns in Great Britain and Japan. With dual-Doppler scanning lidar technology, two measuring devices are operated synchronously at different onshore locations. They are aligned in such a way that the laser beams cross at a point up to 10 kilometers off the coast – at a typical wind turbine hub height – returning, potentially, highly accurate information on wind conditions. To prove this, two measurement campaigns started to compare these data to offshore met mast measurements in order to evaluate the technology´s performance. As well as wind speed accuracy, the comparison of the measurement methods could even reveal advantages in the area of turbulence measurement.

Fraunhofer IWES, together with its partner companies Tetra Tech RPS Energy Limited and Geowynd Limited, was commissioned by the Netherlands Enterprise Agency (RVO) to further develop the 565 km² Doordewind Wind Farm Zone (DDWWFZ). The contract, lasting ap-proximately two years includes the planning of upcoming offshore geotechnical site investigations in DDWWFZ, the development of a fully Integrated Ground model (IGM) for the entire Investigation Area and the preparation of a comprehensive Geotechnical Interpretative Report (GIR). The aim of the project is to prepare, interpret and integrate marine exploration data in order to enable potential investors to assess the cable, layout and foundation conditions within the DDWWFZ and assist their preparation and submission of bids within the Wind Farm Zone.

Setting sail for more sustainable, climate-friendly shipping - this was the motto of Windship Day 2024, which was held on Wednesday, 4 September 2024, on board the four-masted barque ‘Peking’ in Hamburg's Hansa Harbour. The event was organised by the Fraunhofer Working Group for Sustainable Maritime Mobility (under the joint leadership of Emden/Leer University of Applied Sciences and the Fraunhofer Institute for Wind Energy Systems IWES), MARIKO GmbH, the GreenShipping Lower Saxony Competence Centre, the International Windship Association and the German Harbour Museum, which is home to the ‘Peking’ at its exhibition site.

Three Fraunhofer Institutes and the Korean Institute of Energy Research (KIER) want to intensify their exchange on hydrogen, photovoltaics and wind energy topics. To this end, a cooperation agreement was signed today in Halle (Saale). The Fraunhofer Institute for Microstructure of Materials and Systems IMWS, the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM, Dresden Branch and the Fraunhofer Institute for Wind Energy Systems IWES are involved. The collaboration is intended to support the faster establishment of a hydrogen economy and sustainable energy supply in South Korea and Germany.

The year 2024 is characterized by a substantial reduction in federal funding for project research. Energy research is particularly affected by this. A 30% reduction in available funding for new projects is looming, compared to the previous year. Against this backdrop, the Fraunhofer-Group »Energy Technologies and Climate Protection« is warning of a massive decline in German industry's ability to innovate in technologies for the energy transition. Nine institutes of the Fraunhofer-Gesellschaft are organized in the group, which play a key role in driving forward application-oriented energy research.

Together with its project partners RWE, ForWind (University of Oldenburg – Institute of Physics), and Helmholtz-Zentrum Hereon, the Fraunhofer Institute for Wind Energy Systems IWES is investigating in the “C²-Wakes – Controlled Cluster Wakes” research project how the total energy yield of offshore wind farms can be optimized. The aim of the project is to utilize an extensive offshore wind measurement campaign and modeling methods to determine if and how large-scale wake effects and the global blockage effect can be reduced in the future. The project is set to make significant contributions to climate change mitigation and ensure reliable and cost-efficient energy supply. To date, little research on this topic has been conducted anywhere in the world. The project is being funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) with a total of around €2.86 million.

Bremen/Gdynia, Poland, March 2024 – The Fraunhofer Institute for Wind Energy Systems IWES has conducted a boulder detection campaign in the Baltic Sea on behalf of Baltic Power for the foundations of the planned wind turbines. It also applied the surveying technology along the planned subsea cable routes for the very first time. The innovative Manta Ray G1 measuring system allows not only the detection of boulders located up to 100 meters below the seafloor but also the surveying of shallower objects along cable corridors. This technology developed by Fraunhofer IWES makes it possible to minimize risks posed by boulders during the installation of wind turbines, offshore substations (OSS), and cables.

Oldenburg – Fraunhofer Institute for Wind Energy Systems IWES is joining forces with ENERTRAG SE to assist in planning an expansive onshore wind farm as part of Hyphen’s green hydrogen project in Namibia.

Research at Fraunhofer-Gesellschaft would be inconceivable without its employees, including those with migration backgrounds - they are the foundation of our scientific system. Internationality, diversity, and respect are integral components of the Fraunhofer mission statement and the Fraunhofer Code of Conduct.
