Greenhouse Gas Emission Analysis for Distributed Energy System

Greenhouse effect directly affects human health. The literature firstly introduces greenhouse effect and the distributed energy system. Four systems including one natural gas micro-turbine system, one internal combustion biogas engine system, one Phosphoric Acid Fuel Cell combined heat and power system and one Proton Exchange Membrane Fuel Cell system are taken as the targets. Greenhouse gas concentration and emission rate measurements for carbon dioxide (CO₂) and methane (CH₄) were conducted in the exhaust stack. The mass emission rates are normalized to power output and reported as grammas per kilowatt hour (g/kWh). The greenhouse gas emission for the systems at different load ratio and emission for per kWh are analyzed and compared with thermal power plant emission. It is concluded that distributed energy system has bright prospects.
