TRIĒRĒS is Greece’s first Hydrogen Valley brings together business, knowledge and regional interests. The TRIĒRĒS Valley starts as a small scale Valley but has a tremendous upward perspective over a large part of the Balkans, South-Eastern Europe and the wider area of Eastern Mediterranean. The Valley will be built around the nucleus of MOH’s Corinth Refinery complex. From a business perspective the project has strong transeuropean interest as 80% of the refinery sales are generated outside of Greece, rendering it internationally oriented by default. Creating and building a Valley using the refinery as Hydrogen generator accelerates the transition, with an annual production of 2,410 tons of Green Hydrogen that will be utilised in the production of low and no Carbon footprint energy and industrial products and will be injected in the natural gas grid creating a Hydrogen Backbone of full EU interest. High visibility actions in mobility will include one (1) short-sea ferry ship, three (3) public transport buses, and at least (two) 2 cars. Knowledge and innovations are spurred through the intensive collaboration with knowledge institutes and SME’s. The participation of the local and regional governments assures the component of public acceptance, understanding and advocacy, generating interest to many parties supporting regional economic growth. The learnings from HEAVENN and WIGA P&G Valleys will be replicated with the specific knowledge of the Greek and broader connected geographies. TRIĒRĒS entails an investment of 115 mil EUR (initially by project partners) up to 408 million EUR (potential direct/indirect leverage of investments). Several thousand people will be employed during the realisation of the valley project, which will promote new skills development. The consortium partners are creating a true new perspective in the region, transitioning from a traditional refinery complex to a state-of-the art future oriented energy and hydrogen ecosystem in the region.

The overall Aim of MUSICA is to accelerate the roadmap to commercialisation of its Multi-Use Platform (MUP) and Multi-use of Space (MUS) combination for the small island market, and de-risk for future operators and investors, by validation to TRL7 and providing real plans to move to mass market commercialisation. The MUSICA solution will be a decarbonising one-stop shop for small islands, including their marine initiatives (Blue Growth) and ecosystems. The overall Aim of MUSICA will be achieved by developing a replicable smart MUP. MUSICA will advance the existing FP7 funded MUP concept developed by the University of the Aegean (UoAeg) and EcoWindWater (EWW), currently at TRL5, to TRL7. The EWW MUP was successfully trialled in Heraclea in 2010 for 2 years, funded by FP7 of €2.8M. MUSICA will provide a full suite of Blue Growth solutions for small island: • Three forms of renewable energy (RE) (wind, PV and wave) (total 870kW), providing high RES penetration and competitively affordable electricity. Three forms of RE provide non-correlated supply. • Innovative energy storage systems on the MUP, provide all required storage for power on the island and platform, as well as electrical output smoothening (compressed water/air storage and batteries). • Smart energy system for the island, including: demand response, modelling and forecasting based on high flexibility services from distributed generation. • Desalinated water made by desalination unit on the MUP powered by RES providing 1000m3 fresh water for a water stressed island. • The MUP will provide “green” support services for island’s aquaculture (pilot 200 tonnes production) This project will demonstrate that the MUSICA MUP is a viable enabling infrastructure for multiple RES, desalination and BG aquaculture services for small islands, that can share the same space and work synergistically together, sharing supply chains. reducing operating and maintenance costs and solving increasing demand for space.

Many elements of an offshore wind farm become more expensive as depth increases: mooring, anchoring and dynamic cables are the most obvious. However, deep water areas also pose additional challenges for installation and O&M strategies. FLOTANT project aims to develop an innovative and integrated Floating Offshore Wind solution, optimized for deep waters (100-600m) and to sustain a 10+MW wind turbine generator, composed by: a mooring and anchoring system using high performance polymers and based on Active Heave Compensation to minimise excursions, a hybrid concrete-plastic floater and a power export system with long self-life and low-weight dynamic cables. The project includes enhanced O&M strategies, sensoring, monitoring and the evaluation of the techno-economic, environmental, social and socio-economic impacts. The prototypes of the novel mooring, anchoring and dynamic cable components, and a scaled model of the hybrid offshore wind floating platform will be tested and validated within the scope of the project. Three relevant environments have been selected to perform the tests: MARIN basin for global performance under controlled conditions; the Dynamic Marine Component Test facility (DMaC-UNEXE) for large scale prototypes tests; and PLOCAN Marine Test Site, for the characterisation of novel materials under real seawater conditions. An expected 60% reduction in CAPEX and 55% in the OPEX by 2030 will be motivated by FLOTANT novel developments including additional sectorial reductions due to external technology improvements. Overall FLOTANT solution, will allow an optimisation of LCOE reaching values in the range of 85-95 €/MWh by 2030.

The INFINITE project demonstrates a 4.8 MW floating offshore wind system at 100m water depth with two key technology innovations. The first is a disruptive and environment-friendly concrete tension leg platform anchored with an innovative tendon-based mooring system. The platform is designed to work with commercially available WTGs and is scalable, modular and self-installing, showing a vast potential for industrialisation. The second is an innovative aluminium dynamic cable design that is safer, lighter, cheaper and allows for more standardisation in O&M. The demonstrator makes use of a cost optimised O&M strategy that increases accessibility and turbine availability. Moreover, best practices for value co-creation with local stakeholders are applied leading to increased public acceptance of offshore wind developments and an improved Maritime Spatial Planning. The innovations result in an LCOE of 85.3 EUR/MWh at project end and set the path to achieve 43.3 EUR/MWh by 2030. An LCA of the technology innovations developed and an industrial roadmap bringing together innovation needs, supply chain readiness and policy frameworks to allow mass production and deployment complement the project activities.

NEXTFLOAT aims at reducing the LCOE and increase the competitiveness of floating offshore wind (FOW) to accelerate large-scale deployment. The project will demonstrate an integrated system composed of X1’s lightweight floating platform with its proprietary PivotBuoy connection system – a novel design for offshore wind platforms that optimizes the structural design, reduces weight of the structure and greatly improves mooring and installation techniques and costs – and 2BE’s 2-bladed downwind turbine – an advanced rotor that requires less material, fewer components, reduced capital and operational costs and improved environmental benefits. The project also proposes innovations to bring cost-efficiency improvements to the dynamic cable by using aluminium as a conductor material. This innovative concept will be demonstrated in MISTRAL site in the Mediterranean Sea. The design of a 14MW fully integrated system will be developed with a strong focus on optimizing the technological solutions for deep waters and making it suitable for different EU offshore sites. In parallel, this design will take into account mass production and large-scale deployment as key elements to make floating offshore wind a competitive renewable energy source. The project will develop an industrialization roadmap for this FOW concept, in order to facilitate the mass production. Finally, NEXTFLOAT will define a commercial plan for future large-scale deployment that integrates cross-cutting aspects to ensure a sustainable replication based on the analysis of costs, life cycle assessment and socio-economic factors.
