Scaling up green hydrogen
With MHP – the most efficient PEM electrolyzer solution for 10 to 100 MW+

Modular, skid-mounted, ready-to-install: The H-TEC SYSTEMS Modular Hydrogen Platform (MHP) is an industrial scale electrolyzer system with unrivalled system efficiency. The Modular Hydrogen Platform is based on proton exchange membrane (PEM) technology, and it allows you to undertake large scale hydrogen production. Using renewable energy to power the electrolysis process, you contribute to the energy transition by turning water into green hydrogen to replace fossil fuels on an industrial scale.

The H-TEC SYSTEMS MHP electrolyzer provides the highest possible electrolyzer efficiency, high availability, and proven maintenance concept, which results in low hydrogen production costs and stable safe operation.

The H-TEC SYSTEMS Modular Hydrogen Platform is a scalable indoor solution with 77% system efficiency for the industrial production of green hydrogen. Scale is achieved by combining 10 MW blocks to build systems with electrolysis capacity of 100 MW and more.

The system is ready for indoor installation on pre-assembled skids. Modularity simplifies scaling and reduces costs. The highly standardized 10 MW blocks are based on proven S450 stack technology. Each 10 MW block is equipped with integrated process water treatment and electric power supply. The system can be optionally equipped with fresh water treatment and hydrogen purification system.

System reliability is guaranteed by our ingenious redundancy and service concept: critical components are installed redundantly and less critical elements can be replaced quickly thanks to an intelligent spare parts management with short reaction times. The 10 MW stack module consists of 12 cascades. Individual cascades can be switched off for maintenance or replacement of single stacks - this way the rest of the electrolyzer plant can maintain almost full performance without restricion during this time. Hydrogen from our PEM electrolysis is emission-free and climate-friendly and can be used directly for fuel cells.

PEM stands for Proton Exchange Membrane. A PEM stack uses electricity to turn water into oxygen and hydrogen by electrolysis. The stack is the core working element of the electrolyzer. The more stacks you have, the more hydrogen you can produce.

Our stacks are efficient, reliable, and enable a low levelized cost of hydrogen. The hydrogen produced can be used in a wide variety of applications. We have been making them in Germany for 25 years and we are ramping up hydrogen production with a new stack factory in Hamburg with a total electrolysis capacity of up to 5 gigawatts.

Modularity increases the reliability of the electrolysis systems. There are independent controls at stack cascade level, single stacks can be exchanged quickly and easily. We offer a 360° service package with performance guarantee and 24/7 remote monitoring. Our customized maintenance contracts to ensure the best price-performance ratio.

We have always focused on optimizing efficiency and reliability to drive down the levelized cost of hydrogen (LCOH). Our 77% system efficiency for the MHP electrolyzers is now best in class and makes us one of the top electrolyzer companies. This is thanks to continuous work on the reliability of the stacks, fast start up times, and high availability. Our solutions can go from minimal load to nominal load in 30 seconds, ensuring that valuable renewable energy is fully utilized. This flexibility, coupled with high efficiency and reliability enables you to produce hydrogen at a competitive price.

The rush for green hydrogen feels like breaking news but, as one of the top electrolyzer manufacturers, we’ve been working on it for 25 years. Time for us to hone the reliability and efficiency of our core systems. Now it’s time to scale up green hydrogen and we have the backing of MAN Energy Solutions and VW Group, which gives us direct access to practical expertise in large-scale plant EPC and product scaling.
