Natural gas is transported through pipelines at high pressure and must be throttled down before reaching end-users. Our system captures the energy released during this pressure drop, converting it into clean electricity and usable cooling — without burning any fuel or consuming any gas.
High-pressure natural gas passes through a radial turbo-expander, where the pressure drop drives the turbine to rotate at up to 40,000 rpm. The turbine shaft connects to a generator, producing electricity. The process is entirely mechanical — no combustion, no emissions, zero carbon output.
There is no single fixed threshold — it depends on the combination of pressure ratio and flow rate. As a general guideline, an expansion ratio of ≥ 1.5 with a flow rate of ≥ 10,000 Nm³/h is typically viable. However, a higher expansion ratio can accommodate a lower flow rate, and vice versa. Share your pipeline operating data with us, and we will assess feasibility for your specific site.
Yes. The system is installed in parallel with your existing pressure-regulation branch, requiring no modifications to the original pipeline. Construction can be carried out without interrupting normal gas supply operations.
Our systems cover a capacity range of 100 kW to 10,000 kW, customised to match your specific pipeline conditions. Each unit simultaneously produces both electricity and cooling energy from the same pressure drop.
No. The system operates in parallel with your existing pressure-regulating station. If any issue occurs, the system automatically switches to the original bypass within 0.2 seconds — gas supply continuity is never compromised. All operating parameters remain within safe limits throughout the process.
30 years. The system is designed for continuous operation with full bypass redundancy, ensuring long-term reliability even in demanding conditions.
The cooling energy produced during gas expansion can be paired with various downstream applications, including:
Ice production — supplying commercial and industrial cold-chain operations
Industrial cooling — process water and equipment cooling for factories and plants
Data centre cooling — reducing or eliminating compressor-based air conditioning for server facilities
District cooling — air conditioning for metro stations, commercial buildings, and residential areas
LNG vaporisation — utilising cold energy from LNG regasification processes
The optimal coupling solution depends on your site's specific cooling demand and proximity to end-users. We evaluate this during the project feasibility stage and recommend the most viable option.
