Combined heat and power and Internal combustion engines and gensets

Energy flows from internal combustion engines and gensets to combined heat and power; their prices have moved together.

Combined heat and power (energy) and Internal combustion engines and gensets (energy): 2 relationships.

How they are linked

1. Energy flow

Physical flow · Direct · Internal combustion engines and gensets → Combined heat and power

Gas engines supply heat and power in CHP plants.

2. Price link: prime mover

Cost and price · Weak · Both ways

Smaller CHP units use gas engines, larger ones gas turbines. Yearly moves correlate at 0.21 with the engine index, a weak link because the two indices cover different machines and different buyers.
