EU Maritime Innovation Projects Advance in €3.4-Billion Funding Selection

Summary

Six maritime innovation projects covering ammonia propulsion, vessel electrification, offshore charging and onboard carbon capture have been selected under the EU Innovation Fund’s latest round. They form part of a €3.4-billion selection spanning 77 projects. Grant agreements remain under preparation, with funding terms and implementation requirements still to be finalised.

Maritime technologies enter grant preparation

EU maritime innovation projects have secured places in the 2025 Net-Zero Technologies call, advancing several approaches to reducing shipping emissions.

The European Commission’s project register lists GAFF, RIPPLE, FIN-SWE-EC, RETRO-EMT, OffshoreCharge and Seatron as invited to grant-agreement preparation.

The selection covers different vessel types and operating requirements. It includes technologies intended to change propulsion fuels, expand battery use, provide charging infrastructure and reduce emissions from existing ships.

Their common status is an invitation to negotiate grant agreements. Final budgets, schedules, technical deliverables and contractual responsibilities will be established through that process. Results are expected in the first quarter of 2027.

Six projects address different operating needs

Project	Proposed development
GAFF	Gas carriers capable of using ammonia, LPG or marine gas oil, with ship-to-ship ammonia bunkering capability
RIPPLE	Ammonia dual-fuel retrofits for four very large ammonia carriers
FIN-SWE-EC	Additional batteries for Finnlines’ Finnsirius and Finncanopus
RETRO-EMT	A feeder containership combining carbon capture, wind assistance and efficiency measures
OffshoreCharge	A 7.5-MVA offshore charging system for electric service vessels
Seatron	Battery-electric conversion of an existing 3,500-TEU containership

Seatron envisages operation on the Bremerhaven–Hamburg–Gothenburg route. FIN-SWE-EC proposes adding 25 MWh of batteries to each vessel, taking installed capacity to approximately 30 MWh per ship. These remain project specifications rather than completed installations.

Electrification connects vessels with infrastructure

The selected portfolio shows that vessel electrification involves both onboard equipment and access to power.

Battery capacity determines how much energy a vessel can carry, while charging arrangements influence where and how it can operate. For commercial deployment, those elements need to fit sailing schedules, port calls and service requirements.

OffshoreCharge addresses the infrastructure side. Its proposed system would enable fully electric service operation vessels to charge at offshore wind farms, extending the application of charging beyond conventional port facilities.

For operators, the commercial assessment will include equipment expenditure, energy costs, charging time and operational flexibility. Funding can support development, but the resulting service must also meet customer requirements.

Ammonia projects retain commercial conditions

RIPPLE forms part of Maersk Tankers’ work on ammonia-capable shipping. The company has stated that proceeding with conversions depends on securing commercial commitments from customers.

That condition illustrates a wider investment challenge. Technical readiness and grant selection can advance a proposal, while contracts and vessel employment provide the commercial foundation for execution.

GAFF’s combination of transport and bunkering also links vessel development with fuel distribution. Such projects will need coordination between shipowners, fuel suppliers, customers and the authorities responsible for approving operations.

Separate fuel projects support the supply chain

The Commission’s selection also includes fuel-production projects relevant to maritime decarbonisation.

Its register identifies Musel GreenMet with e-methanol and biomethanol, VICTORIA with e-methanol, and CATREF with recycled-carbon fuels. All are listed at grant-agreement preparation stage.

Their inclusion matters because the adoption of alternative propulsion depends on suitable fuel becoming available alongside ships and delivery infrastructure.

However, selection across these categories does not establish dedicated supply contracts between the projects. Those commercial connections would require separate agreements.

Carbon-market revenue supports the programme

The Innovation Fund reinvests revenue from the EU Emissions Trading System into innovative low-carbon technologies.

The latest selection spans 77 projects across several industries, so the €3.4-billion figure represents the broader funding round rather than an allocation exclusively for shipping.

For maritime businesses, the immediate development is the progression of a varied project pipeline into contractual preparation.

The next milestones will be signed grant agreements, confirmed investment decisions and delivery schedules. These will establish which proposals move into execution and when their technologies become available for commercial operation.
