The wind energy sector continues growing rapidly even under the pandemic, as an estimated 93GW wind capacity was installed in 2020 globally. After installation, wind turbines are expected to run around 20-25years, during which O&M (operation and maintenance) becomes crucial in maximising the economic and environmental benefits of wind assets. This project aims to develop a complete solution for robotic based inspection and repair of wind turbine blades (WTBs), both onshore and offshore. Firstly, we will integrate thermography and shearography with laser heating, so that advanced lock-in techniques will be achieved for in-situ inspection of both surface and subsurface defects within WTBs. (Current techniques including drone-based are limited to surface defects only). Secondly, a compact and efficient robotic deployment system will be developed which will hold the inspection unit and a robotic repair arm. The robotic system will be operated by engineers working on ground (for onshore wind farms) or on a vessel (for offshore wind farms). When defects are detected and deemed reparable, the repair arm of the whole system will be activated to rapidly repair the faulty area of composite components by resistance welding for joining and/or disassembly. Comparing to the traditional adhesively bonding for repair, the proposed resistance welding with optimised processing would significantly reduce the curing cycles/time with much fewer preparation for surface treatment steps while it will be more easily designed to integrate with robotic arm. The whole system will be operated remotely by engineers working on ground or on a vessel without risking their lives working in the sky on WTBs. Field trials on wind towers will be conducted to validate the system.

Recognising that current storage solutions are unable to stabilize enough the intermittent renewable energy production, new long term energy storage solutions are becoming mandatory. Current long-term energy storage is mainly provided by Pumped-Storage Hydroelectricity (PSH). Compressed Air Energy Storage (CAES) has appeared for decades as a credible alternative but its poor energy efficiency, the need of fossil fuels and the use of existing underground cavities as storage reservoirs have limited its development. Variations to CAES have shown low efficiency, losing a big percentage of energy as heat and mechanical losses. Since the 2010s, there is a strong revival of scientific and industrial interest on CAES, led by China and the European Union (EU). For the EU, leading the new generation of high-efficient, low climate-impact and long-term energy storage research, is key to increase its energy independency. In this context, the main objective of Air4NRG is the development of an innovative, efficient (over 70% RTE), long- term, and sustainable CAES prototype, which can enhance renewable energy availability and offers robustness and safety while increasing cost effectiveness and improving the environmental footprint. At the same time, it will promote innovation and competitiveness in the European energy storage industry, while prioritizing the principles of circular economy and environmental sustainability. Another key factor of the solution is the integrability to the electrical grid system and their intelligent EMS, which will be proven by the end of the project through end user integration activities (TRL5). The project will result in two prototypes: one of them will be a plug and play system fitting into a standard 40ft container with an over ten- hours storage duration, while the other will be a larger-scale system of 200kW with the same duration of storage. The developed system is a rare material-free solution with simple industrial infrastructure needs, allowing its full development within the EU, strengthening Europes position in the energy storage system sector.

The AmBIENCe project aims at extending the concept of Energy Performance Contracting to Active Buildings and making it available and attractive to a wider range of buildings. AmBIENCe will provide new concepts and business models for performance guarantees of Active Buildings, combining savings from energy efficiency measures with additional savings and earnings resulting from the active control of assets leveraging for instance price based incentive contracts (Implicit Demand Response). The willingness to invest in additional sensorisation, ICT an IoT will be increased by offering adjacent other-than-energy services, e.g. related to comfort, security or maintenance. Within the course of AmBIENCe, we will leverage the experience of the project’s business and research partners, and extend this through regional workshops where we will bring together various stakeholders to make an assessment of best practices and learnings. Based on this, an integrated modular concept will be proposed, and a proof-of-concept platform will be developed, to support the creation of Active Building Performance Contracts.

Hydrogen Offshore Production for Europe (HOPE) intents to pave the way for the deployment of large-scale offshore hydrogen production. To this aim, HOPE will design, build and operate the first offshore hydrogen production demonstrator of 10MW by 2025 in an offshore test zone near the port of Oostende in Belgium. The two-years demonstration of a mid-scale concept on a retrofitted jack-up barge will prove the technical and commercial sustainability of renewable offshore hydrogen production, export by pipelines and supply to end-clients onshore. It will also provide an extensive experience to assess the feasibility of 300MW and 500MW offshore concepts. The experience gathered by the consortium members and the maturity levels reached at the end of the project will enable the deployment of commercial large-scale solutions as soon as 2028. HOPE gathers a unique consortium of European players with cutting-edge expertise across the whole hydrogen value chain: an offshore wind power developer, a renewable hydrogen producer, an electrolyser manufacturer, a desalination solutions manufacturer, an offshore hydrogen pipes manufacturer, a research centre, a regional development agency, a strategic consultancy and a renewables communication agency. HOPE will produce a large range of exploitable results including not only detailed designs of replicable offshore hydrogen technologies, operational data and resulting analyses from a first-of-a-kind project but also pre-feasibility studies and techno-economic assessments of two large-scale concepts. Through an ambitious dissemination and exploitation plan, the consortium intends to accelerate the deployment of large-scale offshore hydrogen solutions to contribute to reach the 10 Mt of clean hydrogen produced in Europe by 2030 to decarbonize the European economy and reach our climate goals.

The main project objective is to reduce the cost of energy (LCOE) of floating wind by 50% through the validation of the "PivotBuoy", an innovative subsystem that reduces the costs of mooring systems and floating platforms, allows faster and cheaper installation and a more reliable and sustainable operation. The PivotBuoy system combines the advantages of Single Point Mooring systems (SPM - pre-installation of the mooring and connection system using small vessels) with those of tension-leg systems (TLPs - weight reduction, reduced mooring length and enhanced stability), enabling a radical weight reduction of 50% to 90% in floating wind systems compared to current spar and semi-submersible systems but also enabling a critical simplification in the installation of traditional TLP systems. The PivotBuoy concept, initially conceived by its founder while at MIT, is currently at TRL3 after the proof of concept in a wave tank at 1:64 scale and it is the result of years of experience. The project proposes validating the concept at PLOCAN test site, integrating a part-scale prototype of the PivotBuoy single point mooring system in a 225kW downwind floating platform developed by X1 WIND. By testing in a relevant environment, the project will also validate critical innovations related to assembly, installation and O&M techniques, reaching TRL5 at the project end. The impact of the proposed innovations is sector wide: the system can be integrated not only in X1 WIND downwind platform but in any other floating platforms using single point moorings systems in the wind and in other sectors such as wave energy, tidal and oil&gas industries. The project consortium, combining experienced industrial partners from the oil&gas, naval and offshore wind sectors with cutting-edge R&D centres, will also bring additional innovations in components, materials and installation and O&M techniques, advancing the state-of-the-art of the floating wind sector.
