BRIN Calls Natural Gas As An Alternative Gasoline Because Effectively Reduce Emission 20-25 Percent

JAKARTA - Researcher from the National Research and Innovation Agency Hari Sumartono said the use of natural gas was an alternative to gasoline fuel because it was effective in reducing emissions that caused air pollution by 20 to 25 percent. “ Due to the chemical composition of CNG or natural gas, the majority is 90 percent methane, resulting in less CO2 emissions than gasoline, it could be 20-25 percent lower,” he said when contacted by ANTARA in Jakarta, Thursday, September 29. He explained that there are three kinds of gas used in Indonesia, namely Liquefied Petroleum Gas (LPG), Liquefied Natural Gas (LNG) and Compressed Natural Gas (CNG). From an economic perspective, according to him, the use of natural gas such as LNG or CNG is beneficial because Indonesia already exists. Meanwhile, LPG still relies on imports and subsidies. “ Can be more effective in LNG from an economic perspective, we don't have to bother importing, in Indonesia there is. Only the problem is if we talk about CNG or LNG, the infrastructure is still difficult,” said Hari. Hari said that some of the advantages of natural gas fuel are technically the value of the octane which is higher than gasoline, which can reach 320 more. This means that the burning inside the engine will be better, especially if the journey rises. “ LPG itself can be above 100 octane, while even the best gasoline is like Pertamax only 92 octane or turbo 95 to 98 octane,” he said. However, the use of gas fuel is still considered less popular for various reasons, such as the lack of gas refueling station facilities and requiring generally thicker and heavier tubes. “ If we use CNG, we need a special tube because the pressure is very high, 200 times the atmosphere pressure so that the tube is special, thick and heavy. The recharging infrastructure is also less than LPG, which is 3 kilograms, buys in stalls, ” Hari said. In addition, those who use LPG as fuel are not allowed to park in the building basement because if it leaks, LPG's gas properties that are heavier than air cannot get out and will be easily ignited by fire.
