Qualified Energy Recovery A Green Power Technology No additional fuel consumption Near zero emissions with air cooled OEC Inside the fence installation.

Qualified Energy Recovery

A “Green” Power Technology

No additional fuel consumption

Near zero emissions with air cooled OEC

Inside the fence installation on existing sites.

No water consumption with closed loop operation

No creation or disposal of waste

Displaces fossil fuel based energy

No new transmission required

Qualified Energy Recovery

A “Green” Power Technology

NEVADA: AB 429 accepts “Qualified Energy Recovery” from non electrical generating sources such as mining processes, as eligible for RPS

NORTH DAKOTA: Pipeline Compressor GT Exhaust Gas Energy Recovery Is “eligible for green tags or green energy sales”
