Energy Recovery from Waste Pressure
The Turbo Expander Generator converts pressure energy into rotational energy through the expander wheel, reducing gas pressure and lowering temperature.
Turbo Expander Generator Operating Principle
- VGN (Variable Geometry Nozzle)
- Maintenance of constant pressure reduction ratio through automatic control
- Expander Wheel
- Conversion of gas pressure energy to rotational energy
- Gear Module
- Transfer of expander wheel rotational motion to the generator
- Generator
- Electricity generated from expander wheel rotational energy
TEG operates through the following process with radially inflowing high-pressure gas:
1. Acceleration(expansion) at nozzle → 2. Expander wheel rotation due to high-pressure, high-speed fluid → 3. Transfer of kinetic(rotational) energy → 4. Electricity generation.

In order to create a regional hub-based system for supplying electricity, natural gas, heat, and hydrogen from natural gas supply management stations connected to microgrids(small-scale distributed power networks), we are currently running a proprietary Turbo Expander Generator(TEG) at KOGAS's integrated energy hub.
TEG Power Output: 1.5 MW(Pressure differential: 60 barg → 8.5 barg)
- Turbo Expander Generator Installation Status

- November 2023 : Completed trial operation
- December 2023~ : In normal operation
Application
The Turbo Expander Generator(TEG) can generate electricity by recovering pressure that would otherwise be lost during natural gas transportation. Natural gas is transmitted at high pressure for long-distance transportation, and pressure reduction stations lower the pressure for use at consumption points.
While conventional pressure reduction stations simply waste pressure energy during the reduction process, implementing TEG allows this energy to be recovered and converted into new electrical power.

Letdown Stations
By lowering the pressure of high-pressure natural gas, steam, and process gases in a variety of industrial sectors, including petrochemical operations, pressure energy is recycled beyond natural gas pressure reduction stations.
