Hydrogen from the region - for the region
Decentralized hydrogen production
with PEM electrolysis
With PEM (Proton Exchange Membrane) electrolysis, you can rely on one of the most efficient technologies for hydrogen production. Thanks to its compact design and fast reactivity, the hydrogen electrolyser can convert surplus electricity, for example from renewable energies, directly into high-purity hydrogen.
The high dynamics of this hydrogen electrolyser also enable it to react flexibly to fluctuating energy sources, which makes it particularly suitable for integration into green energy systems. This allows you to produce hydrogen cost-effectively and sustainably – the key technology for a clean future.
Our PEM electrolysers are based on cascadable stacks that each generate up to 200 Nm³/h of hydrogen. The PEM stacks can be regulated between 10 and 100 percent of the nominal output and quickly adapted to load changes. The standardized modular design of our greenelectrolyzer series is ideal for system sizes with nominal loads of up to 50 MW.
This speaks for FEST as the perfect partner
Our electrolysis systems are based on state-of-the-art technology and offer maximum efficiency in the conversion of water into green hydrogen. This enables particularly cost-effective and environmentally friendly production. We offer flexible solutions that are tailored precisely to the needs of our customers.
Our team consists of experienced engineers and specialists who not only have extensive knowledge of hydrogen technology, but also decades of experience in the automation of industrial processes. Our customers benefit from this experience at every stage - from planning to operation and maintenance.
The Schmidt-Kranz Group includes companies that have been working with hydrogen for 20 years in the field of compressors and high-pressure components. This allows projects ranging from electrolyzers to complete hydrogen filling stations and storage solutions to be implemented. You benefit from comprehensive and technologically leading solutions.
