conversion.

A supercritical CO₂ Brayton cycle converts blanket heat to grid electricity at high efficiency in a compact footprint — printed-circuit heat exchangers, integrally geared turbomachinery, and a dry-cooling option for arid sites.

Why sCO₂ Brayton
REASON 01

Efficiency in a small box

Supercritical CO₂ is dense, so turbomachinery shrinks dramatically versus steam at the same output. The energy island fits on a fraction of the pad.

Cycle efficiency
REASON 02

Printed-circuit exchangers

Diffusion-bonded PCHEs handle the pressure and temperature in a fraction of the volume of shell-and-tube, and they tolerate rapid thermal transients.

REASON 03

Dry cooling for arid sites

Air-cooled rejection means the plant can site where water rights don't exist — the western siting problem, solved at the cycle level.

Convert heat to revenue.

Power conversion is where thermal duty becomes a saleable product. We supervise the whole island.
