JAKARTA - Pertamina's Gas Subholding through PT PGN LNG Indonesia (PLI) is increasingly optimistic in the context of converting fuel oil to LNG fuel using the Diesel Dual Fuel (DDF) system on the train mode of PT KAI's power plant. After being observed, the dynamic test of DDF on the Dharmawangsa train generator Jakarta - Surabaya showed the efficiency and value of substitution of diesel by gas/LNG.

“The dynamic test was successfully carried out. The cumulative efficiency obtained in the DDF system is 37 percent. Meanwhile, the efficiency of the existing Diesel Engine Generator (DEG) system is 35 percent," said PLI's President Director, Nofrizal in his statement, Monday, July 4.

Furthermore, the trials were also carried out to obtain the substitution value for diesel energy or the amount of gas used in the DDF system.

"In terms of gas substitution with an average load of 22 percent, the dynamic test can provide substitution of about 43 percent of the existing fuel. The converted train has a power capacity of 500 kVA. Based on the data we have obtained, if it is 100% loaded, the fuel consumption of DEG can reach 110 liters per hour,” said Nofizal.

In this trial using the Fumigation System for Diesel Engines. This system is the simplest DDF system, does not need to make major modifications to the diesel engine and is easier to restore to the original engine. In addition, it can be adjusted according to the settings on the DEG engine belonging to KAI.

"All trials can be carried out properly and can be accepted by PT KAI. It is hoped that it will run according to the target, namely encouraging efficiency at PT KAI. This is because the fuel subsidy is quite large, given the continued increase in global fuel prices. Apart from that, of course it really encourages the utilization of CNG," said Nofrizal.

The LNG to be used comes from Jambaran Tiung Biru or the East Java LNG Terminal or other sources can be used and support the utilization of LNG for trains.

“From the trial, we got an overview of the operation of the DDF system and the results show that LNG has the opportunity to be used as fuel for train generation. No less important, supporting PGN's role can develop new business potential in this infrastructure sector by providing natural gas energy for land transportation," concluded Nofrizal.
