How Combined Heat and Power Works in Greenhouses

Combined heat and power systems (CHP) provide a profitable and sustainable solution for greenhouses. Greenhouses can reduce operating costs by implementing a Caterpillar CHP system using clean pipeline natural gas as a fuel source. Cat® gas generator sets can provide electricity for electrical loads, heat energy for warming of the greenhouse and recycled carbon dioxide from the engine exhaust as an organic fertilizer.

By generating thermal energy and electrical energy simultaneously, a CHP system can yield a fuel efficiency rate over 90%, versus the typical boiler efficiency of 40-50%. Typical payback on these systems is less than 3-4 years.
