Label Date May 9, 2018
From United States
Maturity stage TRL 7 - Prototype testing in the real world

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.

The Environmental Benefits

  • Low-temperature power conversion of recovered heat
  • Unique design maximizes efficiency
  • Common materials that keep costs low
  • Designed for long service life
  • Can be used in combination with other renewable energy systems
  • Can be applied to industrial or remote power generation processes, such as diesel generators or natural gas generators.

The Financial Benefits

  • 2-6 year payback time for typical customers, depending on operating profile and avoided electricity or fuel cost.
  • Can generate $230,000 in social benefit from avoided pollution emissions from the grid.
