Gas expanders in pressure reduction stations: energy from existing infrastructure

Pressure reduction stations in the natural gas distribution network represent an unexplored opportunity for clean energy generation. Traditionally, the potential energy of gas pressure is dissipated through valves, but modern gas expanders allow converting this energy into electricity, creating value from an otherwise dissipative process.

The installation of gas expanders in pressure regulation stations does not require substantial modifications to existing infrastructure and can generate electricity with zero direct emissions and without additional fuel consumption. This technology, already successfully implemented in several European distribution networks, offers a typical payback between 4 and 6 years and significantly contributes to the overall efficiency of the gas distribution network, representing a perfect example of energy optimization of existing infrastructure.
