Green hydrogen is the energy of the future. But only if it makes financial sense.

This is exactly where hyworx comes in. Our goal is to manufacture PEM electrolysis stacks that last longer, operate more efficiently, and are more cost-effective - reducing both CAPEX and OPEX at the same time. No compromise between performance and cost-effectiveness. Affordable green hydrogen needs both.

That’s hyworx.
German engineering for affordable green hydrogen.

Durability –
Replace less. Produce more.

Stacks that last longer directly and significantly reduce your CAPEX. We develop electrolysis stacks designed to run as long as possible—because every hour of runtime counts.

Minimal degradation –
Performance that lasts.

Aging costs money. Anyone who uses more electricity to produce the same amount of hydrogen loses money every day. Our technology combats aging—and consistently minimizes your OPEX as a result.

Leakproof
No compromises. Ever.

A leaky stack is not a stack—it’s a risk. Our sealing concept is designed to ensure the stack remains leak-free throughout its entire service life. That’s not just a hope—it’s our expectation.

Efficiency —
Because electricity costs money.

In most applications, electricity is the biggest cost driver. Higher efficiency isn’t a technical gimmick—it’s economically essential. We always keep this in mind when developing hyworx stacks.

Optimal electrode layout –
Details that make all the difference.

While the market standard is a spacing of over 1.2 mm, we work with less than 0.9 mm. That may sound like a small difference – but it’s a huge one. Better layout, thinner electrodes, more cost-effective bipolar plates. That’s our unique selling point – and it’s no coincidence.

Minimized contact resistance –
What matters on the inside.

Every contact point costs power. We use state-of-the-art technologies to keep this loss to a minimum – throughout the entire service life.

Ready for mass production from the start –
Affordable doesn’t have to mean cheap.

Our team brings together more than 30 years of experience in the development and manufacturing of hydrogen technology. We develop stacks that are not only technologically impressive but also economically scalable. Mass production processes, minimized material usage, lean cell design – because the best stack is the one that sells.

Overhaul –
The stack’s second life.

Just scrap it at the end of its service life? Not with us.

We want to offer replacement stacks and refurbishment – at a fraction of the new price. That’s not just economical; it’s consistent.

Small. Light.
Powerful.

Our exceptionally flat cell design allows for more cells in less space—with the highest power density per unit of volume and weight.

Ideal for container solutions and offshore applications. And all this at no extra charge.

Smart Pressure
Boost Efficiency. Cut Costs.

Our stacks generate hydrogen under pressure—eliminating the need for a first-stage compressor in most applications. The oxygen pressure further reduces water carryover. Less effort, more efficiency.

50% Less Flow Resistance –
Efficiency Without Compromise.

Thanks to our special bipolar plate design, we have reduced flow resistance by around 50% compared to the market standard, despite the stack’s flat construction. The circulation pump consumes less energy—overall efficiency increases.

Too much power available?
We’ve got it covered.

Want to profitably use electricity at negative prices? Thanks to optimized stack cooling, hyworx stacks have outstanding maximum power handling capacity.

Maintenance
especially simple

Tighten tie rod nuts? With a simple power wrench—in just a few minutes. No special tools, no downtime, no stress. This is how we envisioned maintenance.

German Engineering –
Quality that speaks for itself.

ISO 22734, EN 13445, ASME in preparation. The highest development and manufacturing standards – not just a marketing promise, but a given.

hyworx - Technologies for the global energy transition

The global energy transition requires new, innovative solutions. Green hydrogen, produced from renewable energy sources, is one of the key technologies for decarbonizing industry and mobility.

Invest in hyworx. With funding from the state and the EU, we are developing the core of this revolution: High-performance PEM electrolysis stacks of the future more maintenance-friendly and with more capacity per m² than anything else on the market.
