Description

Expected Outcome:

Project results are expected to contribute to all of the following expected outcomes:

  • Limit the risks related to wind energy systems (e.g., operational, financial, climate) and thus reduce the wind energy projects’ uncertainties;
  • The European wind energy supply chain strengthens its strategic autonomy, technology leadership, competitiveness, and technology export potential.
Scope:

Proposals are expected to address at least four of the following aspects:

  • Develop and validate solutions to increase the reliability of wind energy systems and their components, thus ensuring security of supply and further reducing the environmental impacts;
  • Develop new methods, computational techniques and tools to analyse and predict the reliability of wind energy systems, considering the analysis of the failure modes of existing systems and including a focus on new analytical approaches, technologies and materials;
  • Develop new methods and tools for condition and health monitoring of wind energy systems and their components;
  • Develop and validate solutions to optimise the operation and maintenance of wind energy systems and their components, for example through improved scheduling and predictive maintenance, autonomous tools, robots and vehicles, semi-automated inspection methods or advanced repair methods;
  • Develop and validate new components to be incorporated in structures’ designs to improve the safety and efficiency on-site during maintenance activities in wind farms;
  • Develop and validate innovative digital tools to facilitate wind farm operation and maintenance, for instance through improved interoperability, decision-making support tools, condition and health monitoring techniques and innovative sensors, while ensuring increased cybersecurity and data sharing.

The solutions proposed have to provide solid evidence to support the choice of the sub-systems and components in focus. They have to be critical for the overall reliability of the wind energy systems. For instance, in the case of floating offshore wind, these could be dynamic cables, moorings and connection systems (electrical and mechanical) and their interaction with complex ocean flows.

Particular efforts should be made to ensure that the data produced in the context of this topic is FAIR (Findable, Accessible, Interoperable and Re-usable).

Digitalisation plays a prominent role under various perspectives, for instance in terms of improved predictive maintenance activities and advanced sensors technologies for diagnostics, condition and health monitoring of the power electronics, and structural health assessment and monitoring.

Projects should aim at reducing downtime and operational costs, enhancing safety protocols for maintenance crews, and increasing the overall lifespan and efficiency of wind energy assets.

These solutions should be easily standardised and/or should take into account current standardisation efforts, notwithstanding the TRL level envisaged for the projects developed under this topic.

Destination & Scope

This Destination includes activities targeting a sustainable, secure and competitive energy supply. In line with the scope of cluster 5, this includes activities in the areas of renewable energy; energy system, grids and storage; as well as Carbon Capture, Utilisation and Storage (CCUS).

This Destination contributes directly to the Strategic Plan’s Key Strategic OrientationsGreen transition’, ‘Digital transition’ and ‘A more resilient, competitive, inclusive and democratic Europe’.

In line with the Strategic Plan, the overall expected impact of this Destination is to contribute to the ‘Ensuring more sustainable, secure and competitive energy supply through solutions for smart energy systems based on renewable energy solutions’.

This destination contributes to the activities of the Strategic Energy Technology Plan (SET Plan) and its implementation working groups.

The main impacts to be generated by topics under this Destination are:

Renewable energy

  1. Energy producers have access to competitive European renewable energy and renewable fuel technologies and deploy them to enhance the EU’s energy security. This will contribute to the 2030 “Fit for 55” targets (in particular, at least 42.5% renewable energy share and aiming for 45% in the EU energy consumption, 5.5% advanced biofuels and renewable fuels of non-biological origin share in EU fuel consumption). It will also contribute to the indicative target of at least 5% innovative renewable energy technology for the newly installed renewable energy capacity. By 2050, climate neutrality in the energy sector will be achieved in a sustainable way in environmental (e.g., biodiversity, multiple uses of land and water, natural resources, pollution) and socioeconomic terms, and in line with the Sustainable Development Goals.
  2. Technology providers have access to European, reliable, sustainable, and affordable value chains of renewable energy and renewable fuel technologies.
  3. Economic sectors benefit from better integration of renewable energy and renewable fuel-based solutions that are among others cost-effective, efficient, flexible, reliable, and sustainable. Such integration is facilitated by digital technologies and by renewable energy technologies that provide network stability and reliability.
  4. European researchers benefit from a stronger community and from a reinforced scientific basis on renewable energy and renewable fuel technologies, also through international collaborations.
  5. European industries benefit from a reinforced export potential of renewable energy and renewable fuel technologies, also through international collaborations.
  6. European industries become frontrunners and maintain technological leadership in innovative renewable energy technologies in line with the energy union strategy.
  7. European citizens, including disadvantaged and vulnerable groups, have access to an energy market that is affordable, fair and equitable, more resilient, uses all different types of local renewable energy resources, and is less dependent on fossil fuels. Local communities benefit from a more decentralised and secure energy system and from multiple uses of land and water. Less citizens experience fuel and energy poverty.
  8. Strategic Energy Technology Plan (SET Plan) implementation working groups on solar photovoltaics, solar thermal technologies, renewable fuels and bioenergy, wind energy, geothermal energy, and ocean energy benefit from a reinforced scientific basis and collaboration on renewable energy and renewable fuel technologies towards meeting the ambitious targets of the European Green Deal.

Energy systems, grids & storage

R&I actions will support the just digital and green transformation of the energy system through advanced solutions for accelerating the energy systems integration and decarbonisation. The developed clean, sustainable solutions will contribute to making the energy system and supply more reliable, resilient, and secure. The solutions will contribute to increase flexibility and grid hosting capacity for renewables through optimising cross sector integration and grid scale storage. They will enhance the competitiveness of the European value chain, reduce pressure on resources (also by making technologies ‘circular by design’) and decrease dependencies.

Innovative and cost-effective energy storage (integration) solutions are developed, that provide flexibility to the energy system, reduce total cost of grid operation and enhancement and that minimise the use of critical raw materials and ensure, to the best extent possible, their reuse and recycling, are key elements of the energy system.

Carbon capture, use and storage (CCUS) and carbon dioxide removal (CDR)

  1. Accelerated development of carbon capture, use and storage (CCUS) as a CO2 emission mitigation option in electricity generation, in industry applications and carbon dioxide removal technologies (including conversion of CO2 to energy products).
  2. Reduced EU’s dependency on imported fossil fuels and increased energy security, reduced energy system’s vulnerability to the impacts of the changing climate.
