What makes EVOLOH different

View products

Lower total cost of ownership

Cost-effectiveness is built into the design. Off-the-shelf power electronics. Simplest balance of plant.

4× lower factory cost.
No proprietary parts.

Enables behind-the-meter projects

Direct-to-DC architecture connects directly to on-site power — no inverters, no grid interconnection, no delays, and native load-following in real time.

No new power electronics needed.

Predictable performance

Our insurance-backed long-term service agreement covers remote monitoring and diagnostics, preventative maintenance, and stack replacements.

Guaranteed uptime.
Proactive, not reactive.

Built to scale

Compact, lightweight stacks shipped in standard containers. Local supply chains mean no import delays, no bottlenecks, and no specialized logistics.

100% domestic supply chain.
No multi-year lead times.

Direct-to-DC (DDC™) architecture

No inverters, transformers, or rectifiers. Connect directly to your DC source.
Native load-following

Rapid response to intermittent power.
Faster deployment

No grid interconnection queues and simplified permitting.

Grid-connected

Off-the-shelf power electronics

High-voltage, low-current design enables the use of standard power electronics.
Reduced integration complexity

Simple balance of plant.
Secure supply

Widely available stack components reduce delays and cost overruns.

The numbers behind the difference

$600/kW: Proven full-system CapEx
4x: Lower factory cost
100%: Secure supply chains

Thin metal sheets on rolls in a machine.

Roll-to-roll manufacturing makes it all possible.

Most electrolyzer manufacturers face 2–5‑year lead times, vulnerable supply chains, and factories that can’t keep up with demand. EVOLOH borrowed roll-to-roll manufacturing, a proven technique from high-volume industries such as solar, batteries, and printing, and applied it to producing stacks. The result is dramatically lower factory costs, faster production, and a manufacturing model that scales to meet your timeline.

Locally-sourced materials.
High-throughput.
Scalable production.
No delays in plant builds.
