Innovative technologies and solutions to improve wave and tidal energy systems

Expected Outcome:
Project results are expected to contribute to all following expected outcomes:

• Advance in the realisation of the Strategic Energy Technology (SET) Plan’s research and innovation priorities and targets for ocean energy;

• Energy producers and consumers benefit from increased performance of wave and tidal energy technologies with the focus on efficiency and flexibility, reduced cost, improved reliability and sustainability, operation and maintenance, robustness and security during all stages of the lifetime of an ocean energy farm from installation, operation and maintenance to decommissioning;

• Efficient and effective support to ocean energy research and innovation through alignment and cooperation among different actors, avoiding fragmentation of efforts providing effectively a significant developmental boost of wave and tidal energy technologies.

• Increased contribution of ocean energy to the energy system, with minimal impacts on health and the environment (notably biodiversity) and at the lowest possible cost.
Scope:
The action contributes to address the Strategic Energy Technology (SET) Plan’s research and innovation priorities [1] and targets [1] for ocean energy focussing on wave and tidal energy development. It will take into account the input defined in this context by the Implementation Working Group on ocean energy (IWG ocean), the European Technology and Innovation Platform on ocean energy (ETIP Ocean) [3] and the European Energy Research Alliance (EERA) joint programme on ocean energy [4] .
The overarching objective is the development and demonstration of cost-effective wave and tidal energy systems that can survive in a harsh ocean or sea environment with minimal impacts on health and the environment and biodiversity. The challenge is open to proposals seeking to steer wave and tidal energy development for different type of resources in an effective way at a European level and to bring these technologies to the market. In this action the following can be considered:

• The development and demonstration in controlled environment of innovative wave energy devices.

• The development and demonstration in controlled environment of innovative next generation tidal energy devices

• The development and demonstration of new sustainable materials in ocean energy converters, moorings and foundations whilst ensuring structural integrity, durability and circularity can be considered.

• The development and demonstration of sustainable tailored mooring and connection of electrical or other power transmission systems (cable system, electrical equipment, ....) for wave and tidal energy devices. Advance combined mooring and electrical connectors or hydraulic power transmission to reduce component cost and number of connection operations, included in systems for sharing an anchor between devices in arrays. Develop novel systems for safe and quick connection/disconnection that do not require large vessels and/or diving teams.

• The instrumentation for condition monitoring and predictive maintenance of ocean energy devices and structures. Apply recent advances in condition and structural health monitoring from other sectors to ocean energy. The use of Artificial Intelligence (AI) in ocean energy technology development.

• Advanced manufacturing of ocean energy devices and structures and auxiliary equipment considering reduced energy, manufacturing costs and materials consumption, high production throughput and optimization of logistics.

• Development of technologies and solutions for the installation, maintenance and decommissioning of wave and tidal energy devices.
The validation and demonstration of new ocean energy technologies should be done in a controlled environment meaning that this is done under monitored and reproducible conditions, using for instance, test rigs and test tanks, semi-enclosed basins, or dedicated real-sea demonstration sites with instrumented monitoring infrastructure.
Structure, breakdown of activities and budget allocation
The action consists of activities directly implemented by the consortium and activities implemented through financial support to third parties. The latter can include cooperation with the activities undertaken by the beneficiaries of the EU grant and may complement them. The R&I activities are divided into three challenges:

• Breakthrough challenge

• Validation challenge

• Demonstration challenge
The breakthrough and the validation challenge can be carried out both through activities directly implemented by the core consortium and through FSTP activities. The demonstration challenge will solely be implemented by the core consortium.
The breakthrough challenge entails actions to develop new solutions, tools and new knowledge to increase the competitiveness of the ocean energy sector and on the acceleration of ocean energy deployment at scale. The aim is that the innovative technologies have been at least validated towards the end of the project.
The validation challenge entail actions to validate technologies, tools and innovative solutions both in a laboratory and in a relevant environment which have been developed in the project or have been developed previously or separately in other European and national projects. FSTP can be used for new illustrative application use-cases demonstrating well defined added value to end users.
In the demonstration challenge the consortium is expected to carry out demonstration activities (up to TRL 7) in line with the priorities set by the SET Plan ocean energy R&I priorities and targets and accelerate the take up of innovation by the industry. The demonstration activities will be selected using the stage gate approach developed by the IEA OES task 12 [5] .
Activities directly implemented by the core consortium
The activities of the core consortium are expected to include direct research and innovation activities in any of the areas listed in scope and in any of the challenges…
