Making green hydrogen cost-competitive with fossil hydrogen
elementarhy
We develop, build, and recycle the elementary component of the electrolyzers, the membrane electrode assemblies (MEAs), which transform volatile renewable energy into hydrogen by splitting water.
Green hydrogen production is the key element on the way to a zero emission society.
Hydrogen
Hydrogen is the fuel of the future. To mitigate the impacts of climate change, we need to decarbonize industry and transportation immediately. Through our technology, we enable the large-scale production of green hydrogen, a vital key to de‑coupling from fossil-derived hydrogen.
We deliver the elementary part to make this happen!
YOUR Solution
We help electrolyzer manufacturers scale green hydrogen by delivering MEA solutions that cut costs, reduce critical raw material use and deliver top-tier performance — built with your needs at the core..
About us
elementarhy has its roots in basic science since 2013 through collaborations with the Leibniz Institute of Plasma Science and Technology, the University of Copenhagen, and the University of Bern, and it is validated by the German Aerospace Center.
As the energy supply in Europe nearly collapsed, the founders aimed to make a change by increasing energy security and sustainability through green hydrogen production.
Built upon revolutionary technologies and energy management, elementarhy was created. Since 2024 elementarhy is an independent company and the technology is funded by the German Ministry of Economics and Climate Protection. elementarhy is dedicated to supply electrolyzer manufacturers with cost-efficient and scalable Membrane Electrode Assemblies.
Our international team is united by a common desire to have a strong positive impact on global challenges with technology and an entrepreneurial spirit – more (H2) from less (Ir)
New: We are doing something a MEA-producer is not supposed to do
And why we do it anyway..
We built forty test benches to develop our own MEAs. Now we run yours on them — your protocol, live data from day one, and every result stays your IP.
Durability decides bankability, and bankability takes thousands of bench hours nobody has spare. We do. Keeping that capacity to ourselves would slow down the only thing we actually care about: hydrogen at scale.
Send us your component spec. Fixed quote within days.
And this is how it works
- Send us your electrode or component
- Run & Monitor. Live data from day one.
- Swap & Repeat. Fast sample changes keep the data flowing
