Current Projects
Marmara Hydrogen Gateway
PROJECT OVERVIEW
The Marmara Hydrogen Gateway is ActivZero’s flagship project focusing on green hydrogen and green ammonia, representing a vital renewable energy infrastructure development in South Marmara, Türkiye.
This initiative is designed as a scalable platform that connects Türkiye’s abundant renewable energy potential and industrial capabilities with domestic decarbonisation needs, as well as with emerging European markets for low-carbon hydrogen derivatives and sustainable energy solutions.
The current development plan outlines an initial electrolyser configuration of approximately 200 MW, with scalability aimed at reaching around 500 MW as the project progresses and commercial demand solidifies.
Situated in one of Türkiye’s key industrial and maritime regions, Marmara Hydrogen Gateway is strategically positioned to support domestic hard-to-abate industries while establishing a clean-molecule supply corridor for green ammonia and hydrogen between Türkiye and European markets.
key points:
RENEWABLE ENERGY INTEGRATION
Marmara Hydrogen Gateway is being developed around a flexible renewable energy strategy, focusing on wind-dominant generation, hybrid renewable configurations and grid integration under evaluation.The optimal energy architecture will be determined through technical and techno-economic assessment as the project progresses.
Responsible Water Strategy
Responsible industrial water sourcing is a core component of the project-development strategy. Alternative water solutions, including treated wastewater and desalination, will be evaluated to minimise reliance on municipal freshwater resources and support environmentally responsible project development.
TECHNICAL DEVELOPMENT & PARTNERSHIPS
ActivZero is progressing the project through structured technical development and engagement with specialist engineering, technology, and industry participants. DNV has prepared a comprehensive pre-feasibility / FEL-1 proposal covering techno-economic optimisation, renewable integration, hydrogen and ammonia architecture, infrastructure requirements, risk and implementation pathways.
SCALABLE DEVELOPMENT
The current development concept envisages an initial approximately 200 MW electrolyser configuration, with potential expansion toward approximately 500 MW as technical development progresses and commercial demand ins established. At full platform scale, the project represents an indicative infrastructure investment of approximately €2 billion, subject to technical validation, optimisation, and development-stage refinement.
GREEN HYDROGEN & GREEN AMMONIA
The Marmara Hydrogen Gateway is being developed to supply green hydrogen and green ammonia for industrial decarbonisation and emerging clean-molecule markets. The platform is intended to serve domestic applications in Türkiye while developing future export pathways for hydrogen derivatives into European markets. With an indicative full-scale production potential of approximately 80,000 tonnes of green hydrogen and around 470,000 tonnes of green ammonia per year, subject to technical validation and optimisation.
Why Türkiye ?
Türkiye combines substantial renewable-energy potential with a major industrial base, established energy and maritime infrastructure, and strategic proximity to European markets.
South Marmara offers a particularly strong development proposition, bringing together renewable resources, energy-intensive industries, established ports and logistics infrastructure, and access to domestic and international clean-molecule markets.
Marmara Hydrogen Gateway is being developed to leverage these advantages — supporting Türkiye’s industrial decarbonisation while establishing a potential future supply corridor for green hydrogen derivatives between Türkiye and Europe.
