A solid oxide fuel cell converts propane or natural gas into electricity through chemistry — not combustion. No carbon monoxide. No nitrogen oxides. No sulphur oxides. No particulates. Just electricity, quietly made.

How it works

Fuel goes in

Propane or natural gas enters the fuel cell where it is reformed to drive a controlled electrochemical reaction between hydrogen and oxygen.

Electricity goes out

No engine. Barely audible. Redde R1 runs approximately 8x longer than a standby generator on the same amount of propane.

Ultra-low emissions

Near-zero carbon monoxide, nitrogen oxides, sulphur oxides, and particulate emissions. Significantly cleaner than any combustion generator.

Most solid oxide fuel cells have to run all the time. Shutting them down damages the internal components. That's why they've always been baseload-only — running whether you need them or not.

Redde solved this. The R1 starts quickly and is designed to be cycled repeatedly. 47 patents protect this capability. No other fuel cell on the market can do this.

The result: a fuel cell that sits idle, watches your battery, and only runs when it needs to.
