Abstract

A key factor that should be taken into account in implementing public transport fuel substitution in Jabotabek area is the feasibility of NGV (new) filling stations construction. This needs to be considered in order that the supply of NGV in the area can be secured. Otherwise, additional demand of NGV (CNG and/ or LPG) for the substitution will not be met. A mathematical model of the feasibility of NGV filling station construction has been developed as a rule of thumb of the construction. The model is then applied to select the location of NGV filling station based on public transport population in Jabotabek area.

Abstract

NGV has been used as a vehicular fuel in Indonesia, particularly in Jakarta. However, the success of this NGV utilization is still in question. Currently, only taxicabs and a view dedicated buses have successfully utilized NGV for us fuel.

Abstract

Indonesia with a huge natural gas reserves distributed in various islands and separated by sea has utilized the gas for domestic energy source and petrochemical feedstock purposes. Transportation of the gas to its consumers can be in the form of either pipeline gas or Liquefied Natural Gas (LNG) schemes. Selection of the scheme chosen is determined based on its economic evaluation and technical reliability. The distribution of gas reserves in various islands segmented by sea in Indonesia in combination with economic activity concentration especially in Java island bring about difficulties in gas development due to the up-front massive investment required on gas pipe laying or LNG plant construction. It is therefore required to find a cheaper alternative to the scheme with an established safety standard application, in order that the domestic gas utilization will be able to be enhanced and thus reducing petroleum liquid import. An alternative that can be significantly considered is micro-cryogenic technology development in Indonesia for constructing a low capacity LNG plant so that a small scule of LNG can be economically produced. The LNG is then distributed to gas consumers at regions which has no existing and will not be viable for new gas network installation. Micro-cryogenic technology application is thought to be developed considering a preliminary feasibility study results. The study found that micro-cryogenic technology is around US$ 0,75 million (68,2%) cheaper than gas pipeline technology to provide natural gas for Gas Demonstration Plant operation at R& D Centre for Oil and Gas Technology "Lemigas"
