* What is NGV?
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_01
Natural gas for vehicle (NGV) comprises mostly of methane. In its natural form, NGV is colourless, odourless, lighter than air. It offers complete and clean burning in engines with lower level of emission than other fossil fuels and possessing 130 octane number. It is regarded as an economical, safe, environmentally friendly fuel for vehicles. For those reasons, NGV has become more popular throughout the world.


* Properties of NGV
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_02
Natural gas has been used as a vehicular fuel for more than 80 years. NGV was first introduced in Italy where more than 300,000 cars are now driven by natural gas. Many other countries, spanning from Americas to Asia and Australia, have adopted NGV as one of the fuels for cars. Today, more than one million cars around the globe are powered by NGV.

Comparative Safety Features of Fuels
Refer to http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_02
for the table comparison for NGV, LPG, Gasoline and Diesel





* Types of NGV engine
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_03

1)Dedicated NGV or the dedicated natural gas vehicle which operates using only natural gas.
A vehicle that operates only on natural gas and is therefore optimized to take full advantage of the high octane inherent in natural gas, thus using the fuel more efficiently. A dedicated vehicle only operates on one fuel.

2) Dedicated NGV or the dedicated natural gas vehicle which operates using two separate fuel systems.

Bi-fuel , a vehicle with two separate fuel systems designed to run on
either an alternative fuel or a conventional fuel using only one fuel at a time. Typically, gasoline/natural gas bi-fuel vehicles are gasoline vehicles converted to bi-fuel operation by adding natural gas fuel storage, pressure regulation and control systems.

Diesel Dual Fuel,- a vehicle designed to operate on some combination of both an alternative fuel and conventional fuel at the same time. Dual-fuel vehicles have two separate fuel systems, though a duel-duel vehicle can operate on one fuel or the other.

* NGV in Thailand History
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_05
1984
NGV made its debut in Thailand in 1984 when a number of Bangkok buses and tuk-tuk taxis underwent the NGV experimental program. Technically speaking, the experiment was a success with satisfactory engine performance being noted. However, the lower cost of motor fuels and the high costs of modifying engines to NGV fuelling at that time made the program not economical.

1993
In 1993, the Anand Panyarachun Administration's policy in addressing the air pollution problems revived the interest in NGV. Funding supports were granted to the Bangkok Mass Transit Authority (BMTA) to acquire 82 NGV buses and the country's first NGV filling station being built by PTT at BMTA's Rangsit depot in Bangkok's northern outskirts.

1999
In 1999, PTT embarked on another trial, modifying 12 petrol engine cars and 16 diesel engine vehicles into oil/gas bi-fuelling. Again, the results were satisfactory.

2000
A larger NGV test program was launched a year later when PTT sponsored the costs of turning 100 city taxis into oil/NGV burning vehicles.

The success led PTT to start a pilot project by PTT bearing the cost of changing 1,000 taxies into NGV powered cars. In parallel, PTT has started building NGV filling stations in Bangkok and adjoining areas.



* NGV Stations in Thailand
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_06

There are three types of NGV stations:

1) Conventional stations are located along gas pipelines and are capable of only filling gas to cars.
2) Mother stations are built along gas pipelines and fill gas to cars and gas tankers.
3) Daughter stations receive gas from tankers which transports gas from Conventional stations for filling on cars.
TT plans to put five NGV filling stations on stream in 2002, increasing to 30 in 2006 to support the growing number of NGV vehicles.

The five NGV filling stations due to be operational in 2002 are:
1) Rangsit NGV Filling Station at BMTA Garage
2) PTT service station operated by Sricharoen Phan Partnership on Vibhavadi-Rangsit Road
3) PTT service station run by Kim Jin Ci near Anusorn Sathan Intersection
4) PTT service station managed by the State Railways of Thailand Cooperative near Mor Chit II Terminus
5) PTT service station near Three head-Elephant musuem, Samutprakarn province
6) PTT service station on Krungthep-Nontaburi Road
7) PTT service station on Pattanakarn Road
8) PTT service station on Rama III Road
9) PTT Service station on Bangna-Trad k.m. 55 near Amatanakorn Industrial Estate, Chonburi Province
10) PTT Service station on Sukhumvit Road, Entrance of Maptaphut Industrial Estate, Rayong Province

* Expense
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_07
Meanwhile, plans are afoot for PTT to turn more vehicles - BMTA buses and garbage trucks for the time being - into NGV fueled.

The NGV fueling kits are relatively expensive because they are imported. A NGV/diesel dual fuel kit costs about 350,000 baht while a NGV/petrol is about 30,000 baht.

To overcome this cost barrier, PTT has proposed Finance Ministry for a cut or a waiver of import tariff for these NGV kits. At the same, PTT has advised the Board of Investment to grant promotional privileges for local production of NGV kit as well as machinery and gadgets required at a NGV filling station.




* NGV Price
http://www.pttplc.com/en/ptt_core.asp?page=ps_pr_fu_ga_ng_08
Generally speaking, NGV is cheaper than gasoline. To promote this clean fuel in Thailand, PTT has made NGV half the price of diesel oil, or 40% lower than gasoline price and 20% cheaper than the LPG whose price is currently subsidised.

The speed of recovering investment incurred in NGV conversion depends how extensive a vehicle is used. In other words, the more the car is run, the sooner the cost can be recouped.

A calculation shows a 1,600-cc taxi fuelled by NGV at 7.33 baht/kg and covers a distance of 400 km a day can recover the investment of 30,000 baht for conversion in only four months.
