Stirling Engine

Stirling engine modules to generate clean electricity from waste heat locally

Identification

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.

Label Date May 2018
From United States
Maturity stage Prototype testing in the real world
Looking For Fundraising to build additional licensing partnerships for heat recovery and power generation, and growing their network in the European and Asian market.
