Where to FillFilling Stations - LocationsCNG station - operated by SembCorp Gas Pte. Ltd.Currently, Singapore's only CNG station, operated by SembCorp Gas Pte. Ltd., is located on Jurong Island.In addition to the current CNG station on Jurong Island, more stations are poised to be operational in the near future. The locations and dates will be announced on the website in the coming months.A wide network of CNG stations has already been established in Malaysia. Petronas, the company who operates these Petrol/Diesel/CNG stations, has announced that the number of CNG stations will even be increased throughout the coming years.Filling your CNG tank is done via the inner filling valve located in the front of your car where your engine is. Open the hood and you will see the red capped valve. Lift the cap open and connect the gas hose form the dispenser and it will plug in with a click. Hoses and filling valves in Singapore and Malaysia are of NGV 1 standard and universal so you will be able to refill in both countries. Filing is as similar to filling petrol.Filling your car with CNG is safe, secure and uncomplicated. Thanks to sophisticated technology and standardized filling tubes, the filling process is as easy and fast as filling a car with Petrol. This is also dependant on the compressor pressure and refueling equipment present at the station. An advantage of using CNG is that during the refueling process, no smelly emissions are emitted. Furthermore, no spillage of lubricious liquids will appear. The fuel nozzle will be clean and tidy.
If the vehicle is filled with CNG for the first time, one will soon realize, that some issues are different from the normal Petrol filling. The reason for that is very simple: CNG is in gas-form, not in liquidized form. Gas has other physical attributes than liquids have. If the cylinder is depleted and refilled with new CNG, the cylinder will get warm (not hot). This is absolutely normal and no reason to worry about. If a gas is put under pressure, the density of the molecules will increase, and therefore the temperature will rise. It will take some time, until the cylinder has adopted the temperature of its environment again.This also has a small effect when refilling the cylinder. If a gas is heated up (the temperature increases), the pressure in that gas increases as well. The dispensers at the filling stations automatically stop dispensing CNG, once a pressure of 200 bar is reached. If a cylinder can theoretically accommodate 18 kg CNG under standard conditions (200 bar pressure, 15° Celsius), the cylinder will carry a bit less than 18 kg. Practically that means that the cooler the cylinder and the temperature around the cylinder is, the more kg of CNG can be pumped into the cylinder.It is absolutely no problem to leave the car in the sun. This heat is never sufficient to heat up the cylinder to a critical point. The cylinders are tested and can sustain a pressure of up to 500 bar - a pressure dimension, which is usually never reached in our daily environment.While the car is driving, a different phenomenon can be observed - the cylinder cools down. Again, this is due to the physical attributes of gases. When gas expands, the density of the molecules decreases, and the temperature drops. A nice side-effect in a warm climate like Singapore.
CNG is dispensed in kg (kilogram) and not in litres or m³. If one considers the above mentioned physical attributes of a gas, it becomes quickly obvious, why a measure for mass (kg) is taken instead of a measure for volume (litre or m³). One cubic metre of CNG under 10 bar pressure has just a fraction of the energy value than one cubic metre of CNG under 200 bar pressure. However, one kilogram of CNG has always the same calorific value, no matter whether it has a volume of 500 litres, or just a volume of 60 litres - under 200 bar pressure.Depending on the size and the number of the in-built cylinder(s), the mileage of one refilling is about 150 to 300 km.Throughout CNG popular countries, Petrol station operators such as SHELL and ESSO also operate CNG stations (see pictures).The "box" on the right side of the Esso-picture, and the box on the roof of the Shell station is the so-called compressor. It compresses the Natural Gas of the filling station to 200 bar - exactly that pressure, which is later in the CNG tank of the car. It strongly depends on the performance of such a compressor, how fast the vehicles at a CNG station can be filled up. Modern High-Tech compressors, such as the "Microbox-110", manufactured by Galileo, can fill up several cars in just a few minutes.
An update.After the conversion, I have to drive my car to Vicom to have it assessed. After the assessment, LTA was informed how well the installation is. It was OK'd so I receive another letter to go to LTA to change my car to Bifuel vehicle.Stamp and sealed as legal bifuel vehicle in their system.This week, the CNG system delivered a record 270km from 12kg of gas.
Posted: 04 August 2007 0035 hrs Photos 1 of 1Dr Amy KhorSINGAPORE: Singapore Petroleum Company (SPC) is likely to be the first petrol company here to provide compressed natural gas (CNG).Authorities are also working with other petrol companies to encourage them to supply CNG.This was revealed by Senior Parliamentary Secretary Amy Khor from the Environment and Water Resources Ministry at the launch of the Energy Smart Hotel Label Scheme by the National Environment Agency (NEA) on Friday.The country's first-ever CNG refuelling station that is accessible to the public is expected to start running by next January.The new CNG station will be located at Mandai Road, just off the Woodlands Road junction.Smart Automobile, which runs Singapore's first and largest fleet of CNG taxis, will build and operate the station.NEA has been checking out hotel premises to single out those which have gone the extra green mile and four of them have been chosen as the first recipients of the new energy label scheme.These four hotels are namely, The Regent, Shangri-la, Intercontinental and Changi Village.Recycling used cooking oil into diesel fuel is one of the initiatives that has propelled The Regent to the top of the list of eco-friendly hotels.Lee Baharrudin, Director of Engineering at The Regent Singapore, said: "We are reducing a lot of waste that is being thrown out by recycling metal, cardboard and even light bulb covers."In its rooms, lights are turned off and curtains drawn to minimise energy consumption.Bottles and newspapers are also collected for recycling.But the hotel's most eco-friendly feature is found in the car park as the boiler system uses energy from air conditioners to heat up the hotel's water tanks, thereby generating zero carbon emissions.Dr Khor said: "Energy efficiency really is a low-hanging fruit in our scheme to promote energy conservation and we think there will be tremendous potential and dividends that we can reap by exploiting this to the max, to encourage greater awareness as well as adoption of energy-efficient measures."The NEA plans to expand its energy label program to include shopping centres and schools
power sia... too bad i can't join in the fun, as cng only for na cars right?
How about SC cars ?
