| Popis: | Thailand is currently the world’s fourth largest producer of crude palm oil. The palm oil mill effluent is proposed to beused for biogas production. A value added option is then proposed by increasing thermal efficiency of the biogas by removingCO2 content and increasing the percentage of methane, consequently turning the biogas in to green gas. In this study, thebiogas and upgrading process for electricity generation with the subsidy or adder in the long term planning is presented. Thisanalysis uses the MARKAL-based least-cost energy system as an analytical tool. The objective of this study is to investigateupgrading biogas with a selected water scrubbing technique featuring least-cost energy planning. The co-benefit aspect ofbiogas and biogas upgrading project is analyzed by given an adder of 0.3 Baht/kWh. The target of total electricity generationfrom biogas is 60 MW in 2012. The result shows that green gas will account for approximately 44.91 million m3 in 2012 andincrease to 238.89 million m3 in 2030. The cumulative CO2 emission during 2012-2030 is 2,354.92 thousand tonnes of CO2.Results show that under the given adders the upgrading project is competitive with the conventional technologies in electricitygeneration planning. |
