Opened

Code: 39034 | Identifier Code: HORIZON-CL5-2026-05-D5-13 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 18/12/2025 | End submission calls: 14/04/2026

The rapid transition to low and zero-carbon solutions in maritime and inland waterborne transport requires port authorities and stakeholders to swiftly adapt to supply large quantities of renewable low and zero-carbon fuels and electricity.

However, this shift poses new safety challenges, particularly in port areas where multiple bunkering operations, import/export terminals, and fuel handling and storage activities coexist. The close location of most ports to cities and inhabited areas raises issues of safety on two fronts: the space deficit due to the difficulty of enlarging the port areas in these locations, (leading to e.g. the storage of various fuels in close proximity), and the broader danger to these inhabited areas due to their proximity to the ports and by extension the storage of these fuels.

To ensure a safe and efficient energy transition, it is crucial to assess and mitigate the risks associated with the introduction of renewable low and zero-carbon fuels in port areas. As not all ports will be able to store every type of clean fuel in the port or neighbouring area, safety of transport and distribution within the port area (including anchorage) should also be analysed.

Shipyards of the future (ZEWT Partnership)

Opened

Code: 39031 | Identifier Code: HORIZON-CL5-2026-05-D5-12 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 18/12/2025 | End submission calls: 14/04/2026

European shipbuilding industry is facing increasing pressure from international players, and there is a need to improve its competitiveness through innovation and technological advancements.

The MARI-4YARD project together with RESURGAM, FIBRE4YARDS, SMARTYards and PENELOPE developed several solutions on materials, processes, AI and skills. Additionally, the project SEUS in Horizon Europe is developing an integrated software platform with the ambition to save time in engineering, assembly and construction at European shipyards.

However, there is still a need to increase the ambition and demonstrate these solutions in medium and small-size shipyards.

Energy-efficient software-defined EVs (2ZERO Partnership)

In the past years a variety of road vehicle technologies on component and sub-system level (e. g. mechanical, electro-mechanical, electro-chemical, etc.) have been developed and offer the potential to be combined and improve user benefits at the embedded system level.

The potential to further leverage these developments with Software Defined Vehicle solutions (e.g. high-level functionality ranging from energy efficiency and performance improvements to personalizing the driving experience) over the lifetime of the vehicle needs to be explored. This would bring together developers working at the embedded system level with those working on high-level functions also to ensure that novel solutions will conform with homologation requirements. Solutions coming from this project must also be compatible with current automotive standards, esp. regarding external infrastructure. Compatibility e.g. with EVSE regarding ISO 15118-20 must be ensured.
