CIRCWIND will develop and validate innovative technologies for current and future wind turbines (WT), to enhance reliability and lifetime, performance, operability and maintainability, as well as to find cost-efficient pathways towards complete circularity in a context where a growing number of WT are reaching their EoL. CIRCWIND’s most relevant results are: - A prototype Fibre-Reinforced Polymer (FRP) material for blades with improved damage-tolerance and fatigue life, using a new multiscale modelling tool and simulation framework. - A circular low Carbon concrete material for offshore floating WT based on a new geopolymer binder and circular lightweight aggregates (CLWA). - New virtual replica-based constitutive models and simulation tools for the FRP material and geopolymer concrete, coupled with monitoring technologies allowing to simulate and predict failure and lifetime, and enabling future digital twinning for blade and substructure components. - Integrated sustainability analysis addressing social, economic and environmental aspects, as well as improved circularity. CIRCWIND will develop its technologies to TRL5, building prototypes and validating them in relevant environmental conditions. Representative components of TLP floater and blade have been chosen, made of geopolymer concrete and FRP materials respectively. These innovations will allow future WT to include circular and cost-efficient materials installed in critical WT components at operating windfarms, ensuring feasibility, sustainability, acceptability and high replicability. Besides, new simulation tools, virtual replicas, DT to improve O&M costs. CIRCWIND consortium has a good balance of academic and industrial partners, which allows the project’s developments to be well-oriented towards real market needs that in addition to the strong dissemination and exploitation plan proposed will maximise future impacts, clustering with relevant Offshore Wind stakeholders.

MADE4WIND aims to develop and test innovative components' concepts for a 15MW offshore Floating Wind Turbine (FWT) consisting of new designs and manufacturing techniques for blades, substructure, and drivetrain. The main results obtained in the project will be: - Novel FWT component design (and validation at reduced-scale): Lighter and recyclable WT blades; Improved TLP substructure (including lightweight floater concept, smaller gravity anchor and lighter tendons); and Improved drivetrain design (by a Compact generator with less rare-earths, and more reliable converter). - New material applications: new blade toughening material; new concrete; and Aluminum rebars for floating substructure. - New manufacturing processes: Preform for manufacturing blades. - Recyclability/Reuse of composites from Blades, concrete from substructure, and Aluminum rebars. - New software tools: Novel maintenance strategy and remote control systems; Improved modelling tool for LCoE analysis; Virtual model of 15MW FWT. - Guidelines: Integrated sustainability assessment; Biodiversity protection strategy; Training pathways for offshore wind local industry; Position paper with Offshore Wind stakeholders. These innovations will jointly allow future FWT to include new circular lightweight materials, minimize the impact of sea habitats, increase operational availability, reduce maintenance needs and minimize LCoE; thus, unlocking the massive deployment of >15MW floating WFs in Europe and worldwide. Partners' expertise will be key for project success, as they cover different expertise along the offshore wind value chain: Academia (SINTEF, AAU, NTNU, IFEU), consultancy (ZABALA), material suppliers (Norsk Hydro, Fibertex), WT components manufacturers (Acciona, Ingeteam, Indar) and WT manufacturer (Siemens-Gamesa). Moreover, in addition to partners' research skills, MADE4WIND proposes a strong dissemination plan, clustering with relevant Offshore Wind stakeholders, to maximise future impacts.

The OYSTER project will lead to the development and demonstration of a marinized electrolyser designed for integration with offshore wind turbines. Stiesdal will work with the world’s largest offshore wind developer (Ørsted) and a leading wind turbine manufacturer (Siemens Gamesa Renewable Energy) to develop and test in a shoreside pilot trial a MW-scale fully marinized electrolyser. The findings will inform studies and design exercises for full-scale systems that will include innovations to reduce costs while improving efficiency. To realise the potential of offshore hydrogen production there is a need for compact electrolysis systems that can withstand harsh offshore environments and have minimal maintenance requirements while still meeting cost and performance targets that will allow production of low-cost hydrogen. The project will provide a major advance towards this aim. Preparation for further offshore testing of wind-hydrogen systems will be undertaken, and results from the studies will be disseminated in a targeted way to help advance the sector and prepare the market for deployment at scale. The OYSTER project partners share a vision of hydrogen being produced from offshore wind at a cost that is competitive with natural gas (with a realistic carbon tax), thus unlocking bulk markets for green hydrogen (heat, industry, and transport), making a meaningful impact on CO2 emissions, and facilitating the transition to a fully renewable energy system in Europe. This project is a key first step on the path to developing a commercial offshore hydrogen production industry and will lead to innovations with significant exploitation potential within Europe and beyond.

The objective of GreenHyScale is to pave the way for large scale deployment of electrolysis both onshore and offshore, in line with the EU hydrogen strategy and offshore renewable energy strategy. GreenHyScale will develop a novel multi-MW alkaline electrolyser platform with factory assembled and pre-tested modules, allowing rapid onsite installation capable of reaching a CAPEX below 400 EUR/kW by the end of the 5-year project. A 6 MW module fitting into a 40-foot container will be demonstrated as the first step in the project, and lead to a minimum 100 MW electrolysis plant located in the ideal hosting environment of GreenLab Skive: a symbiotic, industrial Power-to-X platform capable of replicating across Europe with associated green growth and job creation benefits. The minimum 100 MW electrolysis plant will generate green hydrogen for 2 years from 80 MW directly connected renewables in combination with certified green electricity from a TSO grid connection. GreenLab Skive distributes green electricity from both sources through its unique SymbiosisNet which optimises and exchanges energy in all forms (heat, gas, water, heat) between the industrial park entities and external suppliers and offtakers. The setup enables the electrolysis plant to reach an overall energy efficiency above 90%. The GreenHyScale electrolysis plant will become the world's largest electrolyser system qualified as a TSO balancing services provider, thereby reducing the cost of hydrogen to below 2.85 EUR/kg for an electricity cost of 40 EUR/MWh. Besides, because of the inevitable link between offshore wind and electrolysis, an upgraded high-pressure 7.5 MW electrolysis module suited for offshore applications will be developed. GreenHyScale will form new European green value chains that support the paradigm shift to hydrogen economy and transition to green energy by overcoming both technical upscaling and commercial barriers. GreenHyScale will pave the way towards GW-scale electrolyser plants.

Metallic structures are the backbone in a wide range of industrial sectors e.g. energy, space, aerospace, automotive and metal forming. Metals are, however, not utilised optimally since conservative safety factors are used to mitigate residual stresses known to cause fatigue failure. Using synchrotron x-ray and neutron diffraction techniques, the full 3d stress tensor can be measured within the bulk of a component in a non-destructive manner which is not possible with any other technique. Knowing the actual stress levels and incorporating these into modelling tools will lead to three competitive advantages for companies: 1. Increased lifetime and reduced risk of failure 2. Reduced material usage due to reduced safety factors 3. Reduced time-to-market of new products, materials and processing technologies Diffraction-based techniques have been used for decades in academia but have not yet gained foothold in industry because of a lack of validation, standards and procedures. within the framework of the EASI-STRESS project, the consortium, consisting of large industrial partners and experts from the large facilities and universities bound together by RTOs and a standardisation body, break down the main barriers for industrial use of these strong techniques by 1. Validating the techniques and their accuracy against more widespread (semi)destructive measurement techniques. 2. Developing and implementing protocols and procedures aimed at standardisation for the measurements, in close collaboration with both standardisation bodies and industrial partners to ensure their industrial acceptance. 3. Defining (meta)data formats and software that ensure reproducibility and traceability of the data and enable their incorporation into modelling tools to secure the link between data and reliable end-product. 4. Setting up and validating an industrial test bed service for residual stress characterisation to ensure that all European industries can get a head start on the technology.
