Projecten

Throughout his career George has been awarded several projects which include academic, industrial and consultancy projects, most notably:

2021 Work Package Leader and consortium member of the EC (EU Green Deal) EC funded project: European Scalable Complementary Offshore Renewable Energy Sources (EU-SCORES: Project ID 101036457), awarded by HORIZON 2020. The aim of the project is to prove that the efficient and effective use of offshore renewables (wind-wave-solar) is pivotal in the transition of the EU to become a net-zero economy in greenhouse gas emissions by 2050. 

2020 consortium member of the EC funded project: Verification through Accelerated testing Leading to Improved wave energy Designs (VALID, Project ID: 101006927), awarded by HORIZON 2020. The aim of the project is to de-risk wave energy converters design in terms of components reliability and survivability by developing an integrated and open platform for the testing of critical components and subsystems. 

In 2018 George Lavidas was awarded the Marie Skłodowska-Curie Fellowship for his research project WAVREP (WAVe Resource for Electrical Production, Project ID: 787344), focus of the project was to accelerate the wave energy outreach and technological considerations for Wave Energy Converters (WECs). Since 2015 he has concluded several consultancy projects in the fields of marine energies, offshore wind, resource assessment (solar-wind-wave), feasibility analysis, engineering design, and economic evaluations for commercial projects.

    European Scalable Complementary Offshore Renewable Energy Sources (EU-SCORES)

    Efficient and effective use of offshore renewables is pivotal in the transition of the EU to become a net-zero economy in greenhouse gas emissions by 2050. EU-SCORES will unlock the large-scale potential of the roll-out of offshore renewable energy in multi-source parks across different European sea basins through two highly comprehensive and impactful demonstrations: (1) An offshore solar PV system in Belgium co-located with a bottom fixed windfarm and; (2) A wave energy array in Portugal co-located with a floating wind farm.
    The multi-source demonstrations in EU-SCORES will showcase the benefits of a continuous power output harnessing the complementarity between wind, sun and waves as it leads to a more resilient and stable power system, higher capacity factors and a lower total cost per MWh. These aspects will also improve the business case for the production of green hydrogen within these parks. The full-scale demonstrations will prove how the increased power output and capacity installed per km2 will reduce the amount of marine space needed, thereby leaving more space for aquaculture, fisheries, shipping routes and environmentally protected zones. Additional benefits attained by co-using critical electrical infrastructures and exploring advanced operation and maintenance methodologies supported by innovative autonomous systems will further lower the costs per MWh. The involvement of major project developers and utility companies (EDP, EGP, SBE, RWE, EnBW, Eneco, OceanWinds, and Parkwind) will ensure an accelerated path towards commercialisation of these innovative parks.
    Altogether, through a highly competent, skilled and motivated consortium EU-SCORES will pave the way for bankable multi-source parks including wind, wave and floating solar systems across different European sea basins by 2025, thereby supporting the stability and resilience of the European energy system, while considering sustainability, local stakeholders and existing ecosystems.

    Verification through Accelerated testing Leading to Improved wave energy Designs

    A hybrid testing platform that ensures quality wave energy conversion
    Wave power is one of the most reliable resources for renewable energy utilisation. However, the development of high-performance wave energy converters (WECs) is a complex challenge and requires a solid framework of evaluation tools. The EU-funded VALID project will focus on developing and validating a new test rig platform and methodology for accelerated hybrid testing that can be used across the wave energy sector. By improving the reliability and survivability of the components and subsystems that form WECs, the project aims to establish a standard for future use.

    Objective
    The VALID project will develop and validate a new test rig platform and procedures for accelerated hybrid testing that can be used across the wave energy sector to improve the reliability and survivability of the components and subsystems that form Wave Energy Converters (WECs). The methodology for accelerated hybrid testing combines both physical testing (physical test rigs) and virtual testing (simulated environment, numerical models and data). The VALID Hybrid Test Platform (VHTP) will become the interface that allows for seamless accelerated hybrid testing. With the long-term goal of establishing a standard for future use and making a step-change impact on the sector, the new test rig platform and methodology will be validated for a variety of WECs, critical components and subsystems through three different user cases.

    Often faults in component and subsystems are detected through extensive and costly sea testing in late stages of device development (high TRLs) and finding a problem at late development stages can add significant cost and delays to initial schedules, eventually leading to company’s bankruptcy. Sound testing methods are thus needed to reduce the uncertainties, increase confidence in results, assist and guide the concept and subcomponents design, and thus largely assist in the decision-making progress.

    The new hybrid testing platform with open access for models, testbeds and improved data management are all necessary to lower the cost on future technologies. VALID assembles the full value chain required from methodology and platform development (AVL, Aquatera), technology development (Corpower, IDOM, Wavepiston), LCOE (Julia F Chosaz Consult Engineering) to certification bodies (RINA-C) in order to develop an integrated solution with support from RTO (RISE, Tecnalia, Bimep) and academia (Aalborg University, TUDelft).

    WAVe Resource for Electrical Production (WAVREP)

    WAVREP aims to challenge the notion that wave energy should be considered only at energetic regions exposed to open ocean waters. More than 70% of EU coastlines have moderate wave energy resource of 3000-6000 W/m at deployment depths resulting in lower harsh conditions when compared to open ocean coasts. Most Wave Energy Converters (WECs) are developed for higher operational ranges (ocean coasts), with WEC capacity factors and availability at such areas not exceeding 15% and 40% respectively. Higher latitude regions encompass larger wave environments that can propagate high energy content from 5000-8000 W/m. However, such conditions impose significant stresses on the structural integrity and negatively affect expected energy production of WECs, with final capacity factors not exceeding 15-25% (device dependent). WECs at highly energetic wave environment also require higher survivability considerations and have reduced maintenance times. Such factors result at higher capital, operational and energy costs, hindering WECs cost-effectiveness. Using an interdisciplinary scientific methodology the project aims to provide a WEC that can attain higher availability and capacity factors over 60% and 30% respectively, enhancing its global applicability.
