2 Outline Introduction. Development of CNG Utilization Natural Gas Supply and Distribution CNG Standard Quality Air Quality and Vehicle Emission in Jakarta Policy to develop CNG Vehicles in Indonesia 2

3 INTRODUCTION CNG as alternative and environmental friendly fuel for motor vehicles has been used in Indonesia since The number of CNG vehicles from 1987 to 2000 has increased from 300 units to 6630 units, however in 2004, the number of CNG Vehicles have decreased toward to 1500 units and 1 unit bus (Pertamina( Pertamina,, 2004). Limited numbers of CNG filling station, high price of conversion kit, high investment needed for building CNG filling stations, and lack of participations from private companies and the willingness of the government to support this program are some obstacles that cause this problem. Since the middle of 2005, the government of Indonesia has regulation to develop the use of alternative fuel such as coal, natural gas, green fuel to reduce Indonesia s demand of refined petroleum product. As we knew that since 2002, this country was a net importer of petroleum fuel products. 3

4 INTRODUCTION For the natural gas fuel, the total national gas reserves in 2004 was around 134,015.5 BSCF, with production of gas totalled was around 8,642 MMSCFD of which 58.4% was exported and around 41.6% was used as domestic fuel. For that reason the policy relate to the utilization of CNG as alternative and environmental friendly fuel shall be fully developed and implemented to support diversification of energy and blue skies program in Indonesia especially in urban city such as Jakarta. 4

5 METHOD OF EXPERIMENTAL The Method of Experimental is a Description Research, Data and information is result from the related institution that concern to this topics such as: Directorate General of Oil and Gas, PT. Pertamina (Persero) PT. Perusahaan Gas Negara (Persero( Persero) ) (one of gas transmission and distribution enterprise company) Research and Development Centre for Oil and Gas Technology Lemigas,, and the other. 5

6 RESULT AND DISCUSSION The Development of CNG Utilization Number of CNG Vehicles Year

7 The Development of CNG Utilization The decrease number of CNG motor vehicles may due to some factor such as: Price of conversion kit is expensive (In Indonesia currency is about 8 to 10 million rupiahs). The economical of CNG market price At the present, the price is Rp 1400,- per liter equivalent gasoline, So gas producers may have financial loss due to two main problems, those are CNG economic price and high operation cost of CNG filling station. Limited numbers of CNG filling station Consequently, a long queue was most common encounter at refueling station area. 7

8 Natural Gas Supply and Distribution In Indonesia only a limited area that have natural gas supply and distribution by pipeline. The natural gas distribution networks there are in Jakarta, Surabaya (East Java), Batam Island, Medan (North Sumatra) and Palembang (South Sumatra). The natural gas that be used in Jakarta include for CNG has been supplying from two main sources, that are Pertamina s West Java gas fields and the off shore BP North Java gas fields. 8

11 CNG Standard Quality CNG is the natural gas that has been purified and compressed at the elevated pressure up to 200 bars. Generally, it contains two major components i.e. methane (CH4) and ethane (C2H8). To provide guarantee that the quality of natural gas for CNG motor vehicles is safe for infrastructure and installation equipment at the filling station and motor vehicles, it needed the standard or specification of this fuel. 11

14 Air Quality and Vehicle Emission in Jakarta Based on study from ADB, in 2002 with number of vehicles in Jakarta was around 4.8 million, they were significant contributors (greater than 70%) of PM10 and the nitrogen oxides, and about 20% of the sulphur dioxide emission in Jakarta. 14

15 Air Quality and Vehicle Emission in Jakarta Some factors that cause of height mount contamination of gas emission throw away motor vehicle were: Technology of motor vehicles that be used, (such as conventional euro diesel, euro 2 diesel, reformulated gasoline or CNG). Not yet been obliged the periodic emission test of vehicles. Culture of owner or driver of motor vehicle to conduct inspection and maintenance of motor vehicle Fuel quality availability as requirement environment standard. Limited of usage alternative fuel such as CNG, LPG, Bio diesel etc. 15

16 Air Quality and Vehicle Emission in Jakarta To improve air quality in urban city such as Jakarta, some options to use cleaner fuel may be selected as fuel for motor vehicles, with target of air pollutant is: No. Fuel Target Air Polutant(s) Tech Requirements 1. CNG PM10 Conversion kit or full dedicated 2. Reformulated Gasoline 3. Ultra-low Sulphur Diesel Carbon monoxide Volatile Organic Compounds Nitrogen Oxides PM10 Nitrogen Oxides Catalytic Converters Particle traps 16

17 Policy to Develop CNG Vehicles in Indonesia The policy to improve air quality in urban area in Indonesia has been begun since the blue skies program was launched in The objectives of the program are as follows: To provide a mechanism for effective and efficient air pollution management. To manage air pollution. To obtain better ambient air quality for human health and other organism, and To improve human behavior from an environmental perspective. 17
