25kW Low-to-Medium Temperature

Stirling Engine - Stirling Engine modules to generate clean electricity from waste heat locally.

Cool Energy’s novel air engine uses captured waste heat at between 150 and 400° C to produce clean electricity on-site.

In remote locations, electricity is commonly generated with diesel-fueled generators. Recovering the heat from the exhaust manifold with a Stirling engine - extremely efficient compared to internal combustion engines - can produce extra electricity, thereby reducing fuel consumption. The solution has other applications such as solar thermal and biomass generation, and can allow for significantly reduced fuel consumption.
