EVOLOH Nautilus Electrolyzers

EVOLOH lists Santa Clara, CA as its address and Lowell, MA as its manufacturing center. It develops Nautilus electrolyzers aimed at lowering installed cost for industrial on-site hydrogen, chemicals and fuels production, and renewable power monetization.

The design uses a Direct-to-DC (DDC) architecture without inverters, transformers or rectifiers, a high-voltage, low-current layout, and standard shipping containers, with a 3 MW module pictured. The site quotes $600/kW full-system CapEx. In November 2025 it reported MW-scale AEM tests, and on 18 May 2026 it announced a commercial-scale hydrogen project at a 3M facility.

• Direct-to-DC architecture: no inverters, transformers or rectifiers.
• Nautilus stacks: electrolyzer stacks built for lower installed cost.
• Containerized modules: standard shipping containers, with a 3 MW module pictured.
• High-voltage, low-current design: reduces balance-of-plant electrical hardware.
• AEM testing: MW-scale anion exchange membrane electrolyzers tested, announced November 2025.

On-site hydrogen for chemical or fertilizer plants in Vietnam paired with solar. Electronics and glass manufacturers needing industrial hydrogen. Pilot projects with renewable developers.

The DDC architecture removes inverters, transformers and rectifiers from the system. The site states $600/kW proven full-system CapEx, a company claim. Containerized modules simplify shipping and deployment. A commercial project at a 3M facility shows an industrial reference.

Electrolyzer buyers are pressed to cut installed cost per kW, and architectures that remove power electronics are one route. On-site hydrogen for industry is relevant to Vietnamese chemical, fertilizer and electronics manufacturers using solar power.
