POME : Common Treatment Common POME treatment in Palm Oil Mill : * Dominated by open lagoon technology - Need large area (3-4 ha per plant) - High cost for maintenance and social cost - Requires about 60-90 days for processing before discharged to watercourses - Produce methane gas as green house gas that emitted to atmosphere. * Combination of utilizing POME as fertilizer such as land application and composting, and another treatment such as membrane, chemical coagulation…

CBG for Vehicle fuel

Biogas Production Biogas Upgrading (CO2, H2S scrubbing) Bio-methane compression into CBG

converter kit must be installed for gasoline car. 9

KEUNTUNGAN CBG_Hasil Advantages OfPENGGUNAAN CBG as Vehicle Fuel Sementara FUEL CONSUMPTION AND CAR PERFORMANCE • 1 litre CBG equals to 0.5 litres gasoline of equivalent • Power generated using CBG-fueled slightly lower than gasoline especially at up hill road ENVIRONMENTALLY FRIENDLY • 2 Ways to decrease greenhouse gases : • CH4 mitigation is conducted by methane capture in anaerobic digester. • Emissions reduction by applying CBG in vehicle to replace of gasoline fuel USER FRIENDLY • Only press one Button • Can change the Fuel (CBG to gasoline or reverse) in running or stop condition. • Automatic exchange to gasoline if the pressure low 10

TEKNOLOGI BIOGAS PPKS_Pilot CBG for Household Stove fuelPlant

Compressing up to 15 bar The Cylinder dedicated for LPG 11 Burning time less than 1 hour compared to LPG about 3.5 hours

CHALLENGES OF BIO METHANE FUELLED It is not attractive (especially for mill Owners): • Mill owners are still satisfied with the revenue from sale of CPO • High Investment (reactor, gas engine, biogas upgrading and compressor) • Low Economic Revenue (for electricity, presently around IDR 1050 /kwh + IDR 400 if subtitute Diesel fuel)

POM located in Remote Area • Not easy/economic to Injected to Natural gas pipeline • Connection cost and power loss to national grid line (elctricity) • Dominant vehicle use diesel (converter kit for diesel is high cost and ratio diesel and biomethane is low).

Others • Not yet standardization of technology in Methane capture 12

CONCLUSION

Advantages of Biomethane fuelled from Palm Oil : • Reducing the use of fossil energy. • Increasing the amount of labors • Developing the agricultural sector. • Reducing dependence on fuel imports. • Creating friendly environment • Aplicable for blending with or to replace natural gases Methane capture Implementation in POM is still low due to high investment and no obligation to apply this technology 13
