ELECTRICITY GENERATION FROM LANDFILL GAS LFG collected at the landfill site is used for electricity generation. The gas is pumped out and then underwent pretreatment to remove CO2 and yield CH4 (Figure 4). LFG collecting and processing plant requires a flare station to burn the excessive methane production. Energy from LFG can be transformed into cogeneration system or supplied to power plant and natural gas pipeline. Figure 4 Flow of energy production from landfill gas Sri Hapsari Sulistiorini Electricity Generation from Landfill Gas The reciprocating engine has established for decades and compatible to produce electricity from LFG. Currently it is the most utilized technology for power generation from LFG considering its compact form which is flexible to move from a landfill to another. The acceptable revenue of 1 to 3 MW facility along with reasonable capital cost and low in economic risk are the benefits of this machine (Bove and Lunghi, 2006). However the limited capacity of power plant that can provide sufficient revenue will hold back the development of higher capacity to support increasing demand on energy supply. Moreover air pollution from this power plant is higher compared to the other technologies (Table 2). In case of Australia, reciprocating engine has been used in most all LFG power plants and one of it is in Victoria, the Brooklyn Landfill Gas Project of 1 MW (ABCSE, 2007). GAS TURBINE (GT) Gas turbine is usually applied for combined heat and power (CHP) operations. The operation includes a heat recovery from a simple cycle gas turbine exhaust to produce thermal energy in the form of steam or hot water. The Swanbank 5 MW power station in Queensland is an example of LFG power plant that uses gas turbine (Figure 6). Gas turbine engine can vary from 1 to 5 MW for typical LFG power generation. Landfill Methane Outreach Program (LMOP) reported that gas turbine has high efficiency, especially CHP configurations has 70 to 80% of overall system efficiencies. In contrast, the gas turbine application is reported to decrease because of energy losses of small capacity power plant and low performance due to reduced load (Bove and Lunghi, 2006). The less environment impact of gas turbine, however, should be considered for selecting the operation system. Source: (USEPA, 2007) LFG power generation engine is varied and each of them has benefits and drawbacks. Brief reviews of some traditional and current technologies are depicted in the following.
