## Summary

$297M total raised. Bengaluru factory actively shipping PEM electrolyzers at commercial volumes in 2026. Modular design for distributed hydrogen projects.

## Company Overview

Ohmium is a green hydrogen electrolyzer manufacturer with an operational factory in Bengaluru, India that is actively shipping PEM (proton exchange membrane) electrolyzers at commercial volumes in 2026 — one of the few electrolyzer companies delivering actual product rather than promising future delivery. The company has raised $297 million in total funding and is scaling projects across India and international markets from its manufacturing base.

Ohmium's modular PEM stack design is purpose-built for distributed hydrogen projects: smaller installations at industrial sites, refineries, and fueling stations that need hydrogen at the point of use rather than centralized production and transportation. The modular approach allows customers to start with smaller installations and add electrolyzer capacity as demand grows, reducing upfront capital commitment.

Unlike many US-focused electrolyzer competitors struggling with Inflation Reduction Act rollbacks and domestic content requirement uncertainty, Ohmium's India manufacturing base insulates it from US policy headwinds while qualifying for hydrogen production incentives in multiple jurisdictions. India's green hydrogen mission — targeting 5 million metric tonnes of green hydrogen production by 2030 — provides a massive domestic demand signal, while Ohmium's export strategy serves European and Middle Eastern markets facing their own green hydrogen mandates.

## Frequently Asked Questions

### What does Ohmium make?
Modular PEM electrolyzers for green hydrogen production — designed for distributed projects at industrial sites, refineries, and fueling stations.

### How much has Ohmium raised?
$297M total raised. Factory in Bengaluru, India actively shipping at commercial volumes in 2026.

### Why does Ohmium manufacture in India?
India's green hydrogen mission creates massive domestic demand, while India manufacturing insulates Ohmium from US IRA policy headwinds affecting competitors.

### What makes Ohmium's modular design valuable?
Customers start small and add electrolyzer capacity as hydrogen demand grows — reducing upfront capital and allowing incremental scale-up.

### What type of electrolyzer does Ohmium make?
Ohmium makes proton exchange membrane (PEM) electrolyzers — a technology that uses a solid polymer membrane to split water into green hydrogen and oxygen using renewable electricity. PEM electrolyzers are known for fast response times and compact design, making them well-suited for pairing with variable renewable energy sources.

### Where does Ohmium manufacture its electrolyzers?
Ohmium operates a manufacturing facility in Bangalore, India — one of the first dedicated green hydrogen electrolyzer factories in Asia. This positions Ohmium to serve the rapidly growing Indian green hydrogen market as well as export to global buyers at competitive manufacturing costs.

### Who are Ohmium's target customers?
Ohmium targets industrial hydrogen users (refineries, fertilizer plants), renewable energy project developers pairing electrolyzers with solar and wind, green ammonia producers, and hydrogen fueling station operators. The Indian government's National Green Hydrogen Mission is a major demand driver.

### What is Ohmium's competitive advantage?
Ohmium combines PEM electrolyzer technology with low-cost Asian manufacturing and a modular, scalable design (the Ohmium Stack) that allows customers to start small and add capacity. The India manufacturing base provides cost advantages over European and US PEM competitors.
