Fuel cells, with headroom built in
Hydrogen fuel cells of 80 kW and up total as much as 1.76 MW installed behind the 1.5 MW rating. That margin is engineered redundancy: the system holds its rated output without ever asking every cell to do so.

EmPower 1.5 MW
1.76 MWof fuel cells installed behind the 1.5 MW rating
A megawatt-class hydrogen power plant in a 40-foot container. It arrives factory-integrated, sits on a concrete pad, and delivers primary and backup power with no combustion, no transfer switch, and no CO₂ emissions permits.
Just add hydrogen. You're ready to go.

Always online
A UPS and a generator, in one machine.
A standby generator has to start; a UPS has to hand off. EmPower does neither, because its fuel cells are always online. There is no transfer switch and no gap between grid power and backup power. And if the hydrogen supply is ever interrupted, the battery array alone carries the full load for about 30 minutes.

Standby generatorWaits for the outage, then has to start and transfer.
One container, factory-integrated.

Battery array
A 720 kWh lithium-ion array is standard, configurable from 500 to 1,200 kWh. It absorbs load swings and, if hydrogen supply is interrupted, carries the full load alone for about 30 minutes.
Inverters and heat exchangers
Up to 1.5 MW of inverters deliver AC at 120/208 and 480 Delta. High-efficiency heat exchangers are built in, with connections to your facility's exchangers.
Arrives whole, sits on a pad
Everything ships in a single 40-foot container. Site preparation is a concrete pad and your electrical connection. Then add hydrogen.

Where it goes first
Built for loads that can't wait for the grid.
Data centers
Guaranteed uptime, online months before a utility interconnect. EmPower installs outside the building quickly, or inside if needed, connected to existing super-computer cooling systems.
Commercial facilities
Avoid power disruptions and grid-upgrade delays, expand capacity as operations grow, and keep full control over your own energy supply. One machine for both everyday power and outage protection.
EV charging sites
Bypass grid limitations entirely. Megawatt-class power behind the chargers means a site can open where the utility can't serve it yet, and scale without waiting on the feeder.
Data center heritage
Proven where uptime is the product.
The team behind EmPower has been putting fuel cells under data center loads since 2017, when they worked with NREL to prove that hydrogen fuel cells could power a data center, and then with Microsoft and others to demonstrate that the approach scales.
EmPower is that heritage as a product: the fuel cells, battery, inverters and thermal systems integrated, tested and delivered as one machine.

| Topic | EmPower | Diesel generator |
|---|---|---|
| Emissions | Pure water; no CO₂ emissions permits required | CO₂, NOx and particulates; permitted and increasingly restricted |
| Noise | Near-silent, low heat signature | Engine noise constrains siting and overnight operation |
| Efficiency | Over 50% more efficient as primary or backup power | Baseline; efficiency falls further at partial load |
| Fuel logistics | Hydrogen stores indefinitely without degrading | Degrades in storage; needs polishing, treatment and rotation |
| Load response | Battery buffer absorbs surges instantly | Governor lag on step loads; oversizing is the common workaround |
