IGAS ENERGY GMBH

Their core work

IGAS Energy is a German engineering SME specializing in the design and development of components for proton exchange membrane (PEM) water electrolyzers — the industrial hardware that converts electricity into green hydrogen. Their practical expertise centers on the physical internals of electrolyzer stacks: membranes, bipolar plates, porous transport layers, and electrocatalysts. A defining characteristic of their recent work is the push toward CRM-free (critical raw material-free) electrocatalysts, addressing one of the core cost and supply-chain vulnerabilities of PEM electrolysis. They bring hands-on engineering capability to consortia developing next-generation hydrogen production equipment.

What they specialise in

How they've shifted over time

IGAS Energy's H2020 participation began in 2018 with PRETZEL, which focused on modular stack architecture and wide operating-range performance for high-pressure electrolysis — an engineering challenge around design flexibility. By 2020, with PROMET-H2, the focus had shifted toward material-level innovation: eliminating critical raw materials from electrocatalysts and optimizing individual stack sub-components like membranes, bipolar plates, and porous transport layers. The trajectory is clear: from system-level stack design toward deep materials and component engineering, with cost reduction and supply-chain independence as the driving rationale.

IGAS Energy is moving deeper into materials-level electrolyzer engineering, with a specific focus on reducing dependence on scarce catalytic metals — a direction that aligns strongly with EU green hydrogen scale-up priorities through 2030.

How they like to work

IGAS Energy has participated in both projects as a consortium partner, never as coordinator, which is consistent with the profile of a specialist SME that contributes targeted technical expertise rather than leading project management. They have engaged with 20 distinct consortium partners across two projects, suggesting they work within mid-to-large consortia rather than tight bilateral arrangements. This makes them a reliable specialist contributor to bring into hydrogen technology consortia where component-level engineering depth is needed.

IGAS Energy has built a network of 20 unique consortium partners spanning 8 countries through just two projects, reflecting active participation in substantive pan-European research consortia. Their geographic reach is solidly European, consistent with FCH2 JU and Horizon 2020 project structures in the hydrogen technology space.

What sets them apart

IGAS Energy occupies a specific niche that few SMEs fill: industrial-grade PEM electrolyzer component engineering with an explicit focus on removing critical raw materials from the stack — a bottleneck that directly affects the commercial viability of green hydrogen at scale. Based in Stolberg (near Aachen), they are embedded in one of Germany's historically strong industrial corridors, with hands-on manufacturing context that pure research institutes lack. For consortia building green hydrogen demonstrators or moving toward industrial pilots, IGAS offers the kind of applied component expertise that bridges laboratory materials science and real stack performance.

Highlights from their portfolio

• PROMET-H2
  Their largest project by far (EUR 842,812 EC funding, running to 2024), targeting cost-competitive CRM-free PEM electrolysis — one of the most commercially relevant challenges in European hydrogen technology.
• PRETZEL
  An early FCH2 JU project addressing high-pressure operation and modular stack design, establishing IGAS's foundation in next-generation electrolyzer architecture.
