Size a fuel cell
for your use case.

H2C0 systems are custom-engineered — pick an application to see a typical power range, drag to your target output, and see the diesel CO₂ displaced. Deployed from 0.5 kW (defense) to 70 kW (Rishikesh / THDC).

Hydrogen, in five movements

The cleanest molecule,
end to end.

Click any stage, or watch the lifecycle advance. From the solar farm to the server rack, Umagine works every step.

1
Renewable energy
Solar and wind power an electrolyser — no fossil inputs, no carbon.
2
Electrolysis
Water is split into H₂ and O₂. The hydrogen is captured as our fuel.
3
Storage & transport
Compressed, liquefied, or carried as ammonia to where energy is needed.
4
Fuel cell
H₂ + O₂ recombine in a PEM stack to produce electricity, heat, and pure water.
5
Application
Data centres, telecom, heavy industry, mobility — clean, dispatchable power.
