Our Building Block
RuggedCell™ - The World's Most Durable Electrolytic Cell
Built on century-proven Stuart unipolar alkaline technology with over 1,000 plants installed worldwide, our RuggedCell® serves as the core element of our hydrogen electrolyzers. The RuggedCell is unique among water electrolyzers for its patented unipolar architecture, which delivers the advantages of both PEM and standard alkaline electrolyzers: -They offer the robustness, stability and reliability of alkaline but are reactive, flexible and scalable like PEM. -They are built with simple, strong and lasting materials, with no critical minerals and no PFAS. They are the most durable water electrolysis cells in the market, with plants still operating after 30+ years. -They require little maintenance and offer minimal degradation, with no stack replacement required over a typical project lifetime.
RuggedCell by the Numbers
25+
year of lifespan
The RuggedCell outlasts every other electrolyzer. Made from robust materials and built to last. No platinum group metals or PFAS inside.
0
stack replacements
No stack replacements are required during a project lifetime. Unlike other technologies, the RuggedCell design minimizes replacement parts and simplifies maintenance.
100%
operating range
The RuggedCell delivers the same great performance and purity throughout a range of 0% to 100%.
<0.25%
annual degradation
Thanks to its low current architecture, the RuggedCell has limited degradation, enabling it to deliver superior energy efficiency over a project lifetime.
98%
availability
The RuggedCell is a reliable workhorse with very few moving parts and closed loop electrolyte, significantly limiting failure points.
< 10
seconds response
RuggedCell reacts within seconds. Its dynamic response is perfectly matched with renewables, reducing intermittent power losses.
3 Configurations
3 Standard Modules
We've engineered three standard modules - 12.5 MW, 25 MW, and 50 MW - each integrating the best elements of hydrogen production technology at industrial scale. At the heart of every module are our RuggedCells, delivering the durability and performance that make long-term hydrogen production economic. Our unique modular design allows you to scale seamlessly from a single unit to multi-hundred-megawatt facilities while maintaining consistent performance and reliability. This standardized approach reduces project complexity, shortens installation timelines, and provides the flexibility to expand production capacity as your hydrogen demand grows. Each module is factory-tested, fully integrated, and ready to deliver reliable hydrogen production from day one.
12.5 MW
Capacity* : 5.9 Tpd
Our entry-level module delivers proven performance for emerging hydrogen markets and pilot-scale commercial operations. Ideal for distributed production, remote locations, or projects requiring phased capacity expansion.
25 MW
Capacity* : 11.7 Tpd
Our 25 MW module strikes the optimal balance between production efficiency and deployment flexibility. This mid-scale configuration suits most commercial applications, offering excellent economies of scale without oversizing your initial investment.
50 MW
Capacity* : 23.4 Tpd
Engineered for large-scale hydrogen production and utility-grade installations, the 50 MW module maximizes output per footprint. This flagship configuration delivers the lowest cost per kilogram in high-capacity facilities for ammonia production, steel manufacturing, or synthetic fuels.
