Budget: €20.000.000
Eligible countries:  EU Member States and Horizon Europe Associated Countries. Non-EU/non-Associated Countries may also be eligible if specific provisions are made.
Deadline: 17 February 2026

Description
The Horizon Europe call HORIZON-CL5-2026-02-D3-13 focuses on accelerating the development of robust, cost-effective wave energy technologies through transnational pre-commercial procurement (PCP). It aims to support wave energy converters that can withstand harsh marine environments and reach Technology Readiness Levels (TRL) 7–8 by the end of the action.

Building on the EuropeWave PCP initiative, this call promotes a stage-gate evaluation process aligned with the IEA-OES framework, ensuring that selected technologies have successfully completed Stage 3 (TRL 6) and are ready for real-sea demonstrations. The action is structured into a preparation phase—where procurers agree on performance specifications and finalize procurement agreements—and an execution phase that delivers at least two commercial-scale demonstrators tested over 12 months.

Proposals must include a consortium of at least three legal entities from different EU or Horizon Europe-associated countries, including a minimum of two public procurers. Activities should cover coordination, joint research, and validation of the PCP strategy, with results shared across the European industry to foster standardization and knowledge transfer.

By the end of the action, at least one demonstrator should be ready for operational testing at commercial scale, paving the way for Stage 5 activities (commercial-scale array demonstration) under the IEA-OES framework

Budget: € 16.000.000 (Estimated EU contribution per project: 8.000.000
Eligible countries: EU Member States, Overseas Countries and Territories (OCT), countries associated to Horizon Europe – see list of particpating countries
Deadline: 20 January 2026

Description
The Horizon Europe call HORIZON-CL5-2026-01-D5-17 supports innovation actions aimed at enabling real-time monitoring of both regulated and non-regulated emissions from vessels and port activities in waterfront cities.

The goal is to develop tamper-proof, remote measurement technologies that can track pollutants-including those from alternative fuels-during vessel operation and port processes such as cargo handling, towing, and bunkering.

These tools will help public authorities enforce emission limits and contribute to the EU’s Zero Pollution Action Plan and Smart and Sustainable Mobility Strategy. Projects should also address emissions from other industrial activities within port areas and support harmonized methods for measuring emissions across coastal, inland, and open sea contexts.

The call expects projects to reach Technology Readiness Levels (TRL) 7–8 by completion. Demonstrations should take place in at least six TEN-T ports and align with the Climate-Neutral and Smart Cities Mission, feeding into local Climate City Contracts. Proposals must include collaboration with the Cities Mission Platform, formalized through a Memorandum of Understanding. Outcomes should include validated emission factors, automated reporting systems, and governance models that enhance port-city cooperation on pollution abatementv

The UN Ocean Decade – officially the Decade of Ocean Science for Sustainable Development (2021–2030), is a global movement with the vision to ‘generate the science we need, for the ocean we want’

Ocean Decade Actions are the concrete initiatives carried out across the globe to fulfill this Ocean Decade vision. They tackle one or more of the 10 critical Ocean Decade Challenges that have been identified.

These Decade Actions are led by a wide range of stakeholders including, but not limited to, research institutes, governments, UN entities, intergovernmental organizations and other international and regional organizations, business and industry, philanthropic and corporate foundations, non-governmental organizations, educators, community groups or individuals (e.g. via community-led science initiatives). 

Through its recurring Calls for Decade Actions, the initiative invites projects, programmes, and contributions that tackle these ocean challenges, to be endorsed and labelled as an official Ocean Decade Action.

The Call for Decade Actions No. 09/2025 is the latest opportunity to join this global effort. It welcomes:

• Programmes: Large-scale, multi-year initiatives aligned with Ocean Decade priorities.
• Projects: Targeted efforts that contribute to endorsed programmes.
• Contributions: Financial or in-kind support to the Decade ecosystem.

The call is applicable to all sea basins.

 Why Apply?

Being endorsed as an Ocean Decade Action by the United Nations is more than just a badge of honor—it’s a gateway to global collaboration, visibility, and impact.

Here’s what it unlocks:

1. Global Recognition: Your initiative becomes part of a UN-endorsed movement, signaling credibility and alignment with international sustainability goals.
2. Access to a Global Network: Join a vibrant community of scientists, policymakers, NGOs, and innovators working across disciplines and borders.
3. Increased Visibility: Endorsed Actions are promoted through the Ocean Decade website, events, and global communications—boosting your project’s reach and influence.
4. Strategic Partnerships: The endorsement opens doors to collaboration with other Decade Actions, UN agencies, and funding bodies.
5. Policy Impact: Your work contributes directly to the 10 Ocean Decade Challenges, helping shape ocean governance and sustainable development.
6. Enhanced Funding Potential: While endorsement doesn’t guarantee funding, it strengthens your case with donors and investors by demonstrating alignment with a high-profile global initiative.
