Simpler stacks. Better project economics.

We sell stacks. A well-designed stack reduces the cost and complexity of everything around it — balance of plant, power electronics, installation, and long-term operations. EVOLOH rethought stack design, manufacturing, and deployment from the ground up to drive down material costs, factory costs, and the effective cost of electricity. Built for projects that pencil out.

Simple is our strength.

The Nautilus® 3 MW and 12 MW modules are engineered for simplicity and affordability. Compact, lightweight, and built from earth-abundant materials, they’re designed to reduce system complexity and lower your levelized cost of hydrogen (LCOH). 

  1. No PGMs, PFAS, or caustic electrolytes.
  2. High-voltage, low-current design for off-the-shelf power electronics.
  3. Native load-following — fast response, high turndown.
  4. Ships in standard containers.
  5. Fast stack replacement.

The Nautilus® product line

Our core products, the Nautilus® 3 MW and 12 MW modules, are the building blocks for hydrogen projects at any scale. Both are compatible with off-the-shelf power electronics, ship in standard containers, and are designed for fast replacement with standard industrial equipment. 

Nautilus® 3 MW module

  • Standardized building block for hydrogen projects.
  • 10-foot container.

Nautilus® 12 MW module

  • Same proven Nautilus® architecture at a larger scale.
  • 40-foot container.

Built for any project configuration

EVOLOH’s Nautilus® modules are designed for hydrogen projects at any scale. However you choose to deploy them, we have an option that works for your project. 

  • Turnkey solutions
    No integration partner? We will connect you with our established network of EPCs, integrators, and packagers to deliver a complete solution at any scale.
  • Modules only
    If you prefer to work with your own integration partners, our modules are designed to integrate simply with standard, widely available BoP components. No custom engineering or specialized infrastructure required.

De-risk your project from day one.

De-risk operations

An insurance-backed LTSA means predictable costs, reliable performance, and fewer surprises over the life of your project. 

Stack replacement program

When performance declines, stacks are replaced fast. Replacement takes hours, not days, minimizing downtime and protecting project returns. 

Remote monitoring & diagnostics (RM&D)

Real-time RM&D identifies potential issues before they impact operations, enabling preventative maintenance and extending stack life. 

Periodic maintenance

Regular scheduled maintenance keeps your system running at peak performance, preventing issues before they become costly problems.

Why AEM

AEM combines the proven chemistry of alkaline electrolysis with the compact footprint of modern membrane-based stacks.

  • Low-cost materials; no precious metals.
  • Resilient supply chain; sourced from local suppliers.
  • Proven chemistry; in use for over a century.
  • Simpler end-of-life handling; no stack separation required.
  • Simpler balance of plant; fewer pumps, simpler piping.
