The Stirling Power engine is centered on an advanced Stirling cycle engine – a highly efficient, four-cylinder external combustion heat exchange engine designed and developed by our team of engineers.

No other power generator can match our ability to draw from a wide range of green, renewable resources.

Heat is maintained in one section of the engine where heat is transferred to pressurized hydrogen that expands and pushes the pistons.

Efficiency by Design

The heat that powers our engine is generated by an external source. The heat is maintained in one section of the engine where heat is transferred to pressurized hydrogen. As the hydrogen expands, it pushes the pistons. Next, the hydrogen is cooled in the low-temperature section of the engine by heat-storage devices and liquid coolers. As it expands and contracts, the hydrogen drives the reciprocating motion of the pistons, which is converted to rotary motion via a swash plate that powers an electrical generator.

Real World Applications

The Stirling Power engine is a heat engine. The heat can be provided from an external source or be produced by the combustion of a wide variety of fuels within an integral combustor. The heat is delivered to the engine, with electricity and hot water as an output.

Gaseous Fuels

From wastewater treatment plants, agricultural digesters, landfills or stranded and oil field gasses.

Solid Fuels

Woodchips or other bio-based wastes or resources that are usually discarded or problematic can be gasified into synthetic gas or incinerated into high quality heat.


Convert the heat of the sun into electricity.

Heat Streams

Convert high-quality waste heat streams to high-efficiency energy or use heat generated from conversion of problematic or waste fuels sources such as biomass, flare gas, synthetic gas, liquids or others.
