Waste Heat Recovery Applications

Using the wasted heat (exhaust and cooling fluid) from a diesel generator, the SolarHeart® Engine (low temperature Stirling Engine) could provide as much as a 20% gain in power. For military and remote power applications, where the effective price for fuel can be as high as $15 per gallon and fuel delivery can be extremely difficult, this new boost in fuel efficiency is extremely valuable.

Waste Heat Recovery

The Diesel Generator Situation

  • Diesel Gensets used for remote electrical supply Military, intermittent rural, remote base load (to 5MW)
  • Reciprocating engine with 30% to 40% net efficiency; Delivers 11 – 14 kWh per gallon of fuel
  • Dependable, rugged, established technology
  • Only 30% to 40% of chemical energy of genset is harnessed: ~40% to exhaust stack, ~25% to cooling, ~35% power
  • Fuel price volatile; Fuel delivery often difficult and dangerous; Required maintenance is frequent

Waste Heat Recovery Opportunity

  • Vast amount of waste heat in liquid and gaseous streams - Large opportunity to recover
  • Low temp waste heat recovery economics previously challenging
  • ‘Free’ fuel and low cost SolarHeart® Engine now will support economics and an attractive ROI
