Project description
The H-Lyzer project develops and demonstrates a new electrolysis technology for producing green hydrogen more efficiently and at lower cost. The project scales Shiptown’s membraneless and bubble-free alkaline electrolysis concept from prototype level towards a 2 MW industrial demonstration at European Energy’s Måde site.
H-Lyzer aims to reduce both the capital cost and electricity demand of hydrogen production by simplifying system design, avoiding critical materials, and improving energy efficiency. As green hydrogen is a key building block for Power-to-X and sustainable fuels, lowering both CAPEX and OPEX is essential to making green fuels more competitive and supporting MissionGreenFuels’ Northern Star: the integration of sustainable fuels in transport and industry before 2050.

Project objectives
Develop a scalable H-Lyzer system design
The project will finalise the full mechanical, process, electrical and control design for a 2 MW H-Lyzer system. The design will be based on modular building blocks, making it easier to replicate and scale for future commercial deployment.
Improve electrode performance and lifetime
Together with DTU Energy, the project will investigate and test electrode materials and surface structures that can improve efficiency, durability, and long-term performance.
Manufacture and assemble a full-scale demonstration system
The project will translate the system design into manufactured components and assembled modules. This includes mechanical manufacturing, assembly, quality assurance, and factory acceptance testing before installation at the demonstration site.
Develop power, control, and SCADA systems
AE Partner and Init Denmark will develop the power conversion, control systems, data logging, and SCADA integration. These systems will be designed to support the modular architecture of H-Lyzer and enable safe, efficient, and flexible operation under real industrial conditions.
Demonstration at real-world, industrial scale
The H-Lyzer system will be installed, commissioned, and tested at European Energy’s Måde site. The demonstration will generate performance data on efficiency, reliability, hydrogen quality, and system operation under real-world conditions.
Prepare the technology for replication and commercial deployment
The project will consolidate results from the demonstration into documentation, operational learning, performance data, and readiness assessments that support further scale-up and commercial use.

Impact & outcome
The expected outcome of the H-Lyzer project is a validated 2 MW electrolysis demonstration system and a stronger basis for scaling a new Danish hydrogen technology towards commercial deployment.
The project will deliver data on efficiency, reliability, manufacturability, control, safety, and system integration. It will also provide learning on how a simpler, membraneless electrolysis architecture can reduce system complexity and improve energy performance.
The broader impact is the potential to lower the cost of green hydrogen production and hereby, help make sustainable fuels more competitive.
The project also strengthens the Danish green fuel value chain by bringing together partners across technology development, electrode optimisation, mechanical manufacturing, power electronics, control systems, and industrial demonstration.
Mission fit
H-Lyzer contributes to the MissionGreenFuels portfolio by addressing one of the key upstream challenges in sustainable fuel production: efficient and cost-competitive green hydrogen. The project strengthens the fuel production part of the value chain by developing and demonstrating a scalable electrolysis technology that can support future Power-to-X pathways.
H-Lyzer will also share experience on modular design, industrialisation, manufacturability, and system-level simplification to reach CAPEX/OPEX reductions across the value chain.
