About the IWG
In March 2018, the Ocean energy Implementation Working Group (IWG) adopted its implementation plan (IP). It focuses on developing research and roadmaps that set out the aspirations of the wave and tidal sectors.
The IP aims to transform those aspirations into operational actions. The actions listed in the IP are based on the ocean energy strategic roadmap. This roadmap provided the ground for producing the IWG declaration of intent, which includes a series of targets. The targets for tidal technologies should be met by 2025, and those for wave technologies should be met by 2030.
The OceanSET project is a 3-year Horizon 2020-funded project, developed to support the IWG and carry out the IP’s actions.
Targets and objective
The ocean energy IP outlines 3 high level actions:
annual coordination between EU countries and regions to share and track critical information, in order to demonstrate ocean energy technologies’ progress.
collaboration between EU countries, regions and the European Commission to ensure funds are used effectively and blended appropriately, if possible, to drive large scale deployment
the need for annual monitoring of progress with a review carried out at the end of each phase, in order to decide whether the development of the technology concerned can move to the next phase.
IP targets for wave and tidal sector:
Development of cost competitive ocean energy technologies with high market potential for Europe
Reduce the levelized cost of energy (LCOE) for tidal stream energy to:
15 ct€/kWh in 2025
10 ct€/kWh in 2030
Reduce the LCOE for wave energy technology to:
20 ct€/kWh in 2025
15 ct€/kWh in 2030
10 ct€/kWh in 2035
The Ocean energy IWG identified 11 technology development actions to be carried out at a national and EU level. The actions are both cross-cutting (i.e. relating to all ocean energy technology) and technology specific (i.e. relating to either wave or tidal). They include:
6 technical actions supporting all technology readiness levels (TRLs) to ensure tidal arrays are developed and drive convergence in wave technologies
3 financial actions ensuring that investment and insurance support funds are available to develop the sectors
2 environmental actions to share knowledge on safety and environmental matters.
These actions are detailed as follows:
1.1 Tidal energy technology device development and knowledge building up to TRL 6
1.2 Tidal energy system demonstration in operational environment (TRL 7-9)
1.3 Wave energy technology development and demonstration up to TRL 6
1.4 Wave energy system demonstration and deployment TRL 7-9
1.5 Installation, logistics and testing infrastructure [and] supply chain development
1.6 Coordination of the development of standards and guidelines for technology evaluation and LCOE analysis
2.1 Creation of an investment fund for ocean energy farms
2.2 Creation of an EU insurance and guarantee fund to underwrite project risks
2.3 Pre-commercial procurement action for development of wave energy technology
3.1 Developing certification and standards to support the offshore renewable technology sector
3.2 De-risking environmental consenting through an integrated programme of measures
The IWG is composed of representatives from the EU countries, regions and other stakeholders.

De-risking environmental consenting through an integrated programme of measures
In 2019, the OceanSET project published its first report, providing an overview on the progress made in the ocean energy sector in 2018. Key findings for 2018 include:
• 6 EU countries (out of 11) had an ocean energy policy
• EU countries provided funding of €26.3 million to ocean energy
• EU countries funded 90 ocean energy projects, two-thirds of which support wave energy devices
• 12 ocean energy projects, operational in 2018, were identified as TRL 7 or above
• 3 EU countries gave permission for wave or tidal projects to be carried out
• Test sites enabling demonstration were found in almost all EU countries
• The supply chain in most EU countries was considered robust.
The report is available here. A second annual report was published in March 2021.
For 2019, initial findings on the ocean energy sector's progress indicate that 127 ocean energy projects were being carried out. Of these, 25 ocean energy projects had a TRL 7 or above.
