South Texas Gas Compressor Station


Power Generation at a Stationary Engine Application

GCGE teamed with a natural gas compression services company and a South Texas natural gas field to show that the Power+ GeneratorTM could be used effectively on a gas compressor engine. This project marks the first commercial ICE application of the Power+ GeneratorTM, which captures waste heat from a Waukesha 5794 and generates emission-free electricity that can be used for on-site power needs or supplied to the local electricity grid. The waste heat removed by the Power+ is equivalent to increased engine cooling capacity, a significant benefit for compressor engines in the heat of summer.

“Natural gas compressor stations powered by internal combustion engines are located all over North America, and these waste heat streams can be captured to generate additional power and cool the engine at the same time.  This is energy efficiency at its best, and we expect to see many more ICE applications in the future.

Since the machine went online last year, it has generated 14.2 MWh gross with 95 percent up-time in the past three months, enough to power more than 20 homes. This is the first ICE application of the Power+ Organic Rankine Cycle (ORC) technology, powered by its patented Twin Screw Expander.

ElectraTherm’s heat-to-power technology can convert sources of low-temperature heat (ICE jacket water, biomass, etc.) into power. With 13 units in the field, ElectraTherm’s Power+ GeneratorTM has accrued more than 6,000 hours of fleet run time — more than 11,000 hours, including test cell operations.
