The Maritime Low Emission Network (MarLEN) 2026 Call supports transnational research and innovation projects that accelerate the development and deployment of zero-emission waterborne transport technologies. The programme promotes international collaboration among industry, research organisations, ports, and maritime stakeholders to advance sustainable shipping, maritime decarbonisation, and Zero Emission Waterborne Transport (ZEWT) solutions.
MarLEN aims to strengthen European maritime research cooperation, support innovative clean shipping technologies, and facilitate the transition toward climate-neutral maritime transport through industrial research, experimental development, and real-world demonstration projects.
Overview
The Maritime Low Emission Network (MarLEN) is a European transnational initiative established to support collaborative research and innovation activities that contribute to the decarbonisation of waterborne transport. The programme builds upon previous ERA-NET maritime initiatives and seeks to create a long-term framework for cooperation among European ministries, funding agencies, research institutions, and industry stakeholders involved in maritime innovation.
The 2026 call focuses on accelerating the transition toward Zero Emission Waterborne Transport (ZEWT) by funding projects that develop, test, validate, and demonstrate innovative technologies capable of reducing greenhouse gas emissions from the maritime sector.
The initiative also seeks to strengthen coordination between national and regional research programmes, improve the effectiveness of maritime research investments, and enhance Europe’s global competitiveness in sustainable maritime technologies.

Why This Matters
Maritime transport is essential to global trade but remains a significant contributor to greenhouse gas emissions. Achieving climate neutrality in the maritime sector requires substantial innovation in fuels, vessel technologies, infrastructure, and operational systems.
MarLEN helps address these challenges by:
- Accelerating maritime decarbonisation.
- Supporting climate-neutral shipping solutions.
- Advancing clean maritime technologies.
- Encouraging international research collaboration.
- Strengthening Europe’s leadership in sustainable maritime innovation.
- Promoting commercialisation of zero-emission technologies.
- Supporting long-term environmental and economic sustainability.
The initiative also contributes to broader European climate objectives by fostering technologies that reduce the environmental impact of waterborne transport.
