Pollutant indicators of major gas and fuel equipment in the integrated energy system.

Pollutant	Microturbine	Internal combustion engine	Fuel cell	Gas boiler	Public grid	Absorption refrigeration unit
COX	724	543	486	254	922	171
NOX	0.2	0.15	0.0136	0.54	2.295	0.06
SOX	0.0036	0.0032	0.3327	0.764	3.583	0.0008

Note. The pollutant indicators of microturbine, internal combustion engine, fuel cell, and public grid are based on the production of 1 kWh electricity; the pollutant indicators of gas boilers are based on the production of 1 kWh heat; the pollutant indicators of the absorption refrigeration unit are based on the production of 1 kWh cooling energy.
