# EVOLOH

> EVOLOH is a Santa Clara industrial hardware company trying to make electrolyzers less like bespoke chemical plants and more like repeatable manufactured products. Its Nautilus anion-exchange-membrane stacks use earth-abundant materials, roll-to-roll production and standardized 3 MW and 12 MW modules. The commercial proposition is broader than a cheap stack: simpler balance-of-plant equipment, direct use of intermittent DC power, standard-container shipping, rapid replacement and a long-term service agreement. The strongest public evidence so far is a validated 0.5 MW standard stack, more than 5 MW contracted for 2026 delivery, and a 2.5 MW commercial-scale pilot planned at a 3M facility for 2027.

- **Founded:** 2020
- **Headquarters:** Santa Clara, United States
- **Founders:** Dr. Jimmy Rojas (Founder and CEO), Taylor Huff (Co-founder (reported by Crunchbase))
- **Products:** Nautilus 3 MW module, Nautilus 12 MW module, Direct-to-DC architecture, Long-term service agreement, Nautilus M5
- **Notable:** Raised an oversubscribed $20 million Series A in March 2024 led by Engine Ventures with strategic participation from NextEra Energy Resources and 3M Ventures., SoCalGas reported that a joint R&D project improved hydrogen-production efficiency by 15% and could reduce electrolyzer capital cost by approximately 25%., Signed a 0.5 GW supply agreement with an unnamed US renewable-energy developer in 2024, backed by a non-refundable deposit and contingent on completion of the Lowell manufacturing center.

## Products & services

- **Nautilus 3 MW module** — A standardized 3 MW AEM electrolyzer module packaged in a 10-foot container and designed for off-the-shelf power electronics, load-following and fast replacement.
- **Nautilus 12 MW module** — A larger 40-foot-container module using the same Nautilus architecture for utility and industrial-scale hydrogen projects.
- **Direct-to-DC architecture** — A behind-the-meter configuration intended to connect to on-site DC generation without separate inverters, transformers or rectifiers and to follow intermittent output.
- **Long-term service agreement** — An insurance-backed service package covering remote monitoring, diagnostics, preventative maintenance and stack replacement.
- **Nautilus M5** — An earlier 1 MW advanced liquid alkaline stack recognized by Solar Impulse at prototype demonstration maturity, representing the bridge to EVOLOH's current commercial modules.
