Waste Heat Recovery

Waste Heat Recovery

As energy becomes more expensive, and the ramifications of wasting it become more evident via climate change, the recovery of waste heat is becoming more important.

Waste heat is produced in many industrial processes.  Most energy conversion processes involve the production of heat as a by-product, which is usually wasted.  Internal combustion engines waste around two thirds of the energy in the fuel as heat.  These are prime examples where our technology can be applied to convert some of the heat into electricity.

A key application of our technology is expected to be in hybrid vehicles where it will be used to recover heat from the exhaust.  The electricity generated can be used to help drive the vehicle.  When the vehicle is stationary the electricity can be used to charge the battery.  This is the next big step to improve the efficiency of hybrid cars such as the Toyota Prius.  We also see application to both heavy and light trucks and smaller vehicles such as delivery vans.  The high fuel usage and distance typically travelled annually by these vehicles means the pay back time for the fitment of Cogen technology is quite short - of the order of a year or two even at current fuel prices.

Our technology can be used for recovering heat ranging from low to high grade.  If you have an application you wish to discuss please contact us.
