Iran – Natural Gas Vehicle Country Report Update Sept 06

Based on the 121st article of the third national program of economical, social and cultural development of the country, the Iranian Fuel Conservation Organization (IFCO), a subsidiary of National Iranian Oil Company (NIOC), was established in 2000, aiming to manage the fuel consumption in different sectors through the review and survey of consumption trends and executing conservation projects nationwide.

Establishing compressed natural gas (CNG) infrastructure and the promotion of natural gas vehicles (NGV’s) are among the main missions of IFCO.

NGV programs:

CNG projects were started in 1975 with the conversion of 1200 taxis and private passenger cars in Shiraz city as a pilot project.

These are the main strategies of IFCO for bi-fuel vehicles:
– Retrofit conversion as a short term method for existing cars.
– OEM production of bi- fuel vehicles as a medium term measure.
– Design and production of CNG base OEM vehicles as a long term method

A comprehensive project for creating infrastructure and developing CNG in Iran was started by IFCO in 2001 with some separate activities in parallel, as described below:
– Conversion retrofit vehicles to CNG
– OEM CNG vehicles manufacturing
– Legislation of national directives and regulations
– Construction of CNG fueling stations.


The following outlines some of the main measures taken relating to infrastructure development.

Iranian CNG Station

CNG stations: Existing large natural gas resources and pipeline networks that cover more than 560 cities and 3226 villages form the basis for the location of CNG stations in the country.

Up to Sep 2006, 326 CNG stations have been constructed and are in service while more than 432 stations are under construction by the government and private sectors. The total capacity of the service stations is more than 10,000,000 m3/day (6.000.000 m3/day is in service and more than 4.000.000 m3/day is ready for operation)

Public relations: Safety aspects and the promotion of natural gas vehicles have been addressed through many educational films produced and broadcast on TV and radio channels. Brochures including safety requirements for use natural gas as vehicles fuel, specification of natural gas, etc, have also been issued. In several national and international fairs, IFCO has also raised awareness about natural gas vehicles.

Regulations and standards: International standards (ISO Standards), European Regulations and standards of countries with historical background on CNG such as Italy, Argentina and New Zealand have been used for different activities related to CNG in both vehicles (light and heavy duty) and refueling stations since the beginning of the project in Iran. Also some important regulations regarding NGV’s and CNG refueling stations have been issued by IFCO.

After a short interval the national standards based on ISO standards were issued for CNG vehicles and their components (ISIRI 5636 and ISIRI 5764), and at present the country is switching CNG vehicle components standards from ISO standards to European regulation R110 and first edition of national NGV’s standards (ISIRI 7598) has been recently published based on R110 regulation.

A national standard of CNG stations was published in 2005 with code no. ISIRI 7829 based on the Argentina (GE-N1-118), United States (NFPA 52), and New Zealand (NZS 5425 Part 2) standards and considering Iran’s climate and geographical circumstances.

Supporting related research: IFCO supports a number of research projects related to CNG engine performance (dedicated, Bi-fuel, Dual-fuel engines), fuel conservation projects, natural gas vehicle durability, emissions and other associated topics such as the identification of natural gas treatment as a vehicle fuel, gas composition effects on engine performance, etc. CNG based engines and native NGVs have been developed by country research centers and car manufacturers.

Localization of CNG components and equipment production: Transferring technology from abroad and the localization of CNG kit components, cylinders and CNG stations equipments are some of the strategies of IFCO. Construction of a CNG cylinder production factory with a nominal capacity of 120 thousands cylinders per year in different dimensions has been completed and now supplies a portion of the country’s requirements according to present international standards. Another CNG cylinder production factory is under construction in Esfahan with more than 200 thousands cylinders per year. Other CNG cylinder production factories are also being planned. Local compressor manufacturing companies are producing major parts of CNG station equipments with the co-operation of foreign companies.

Conversion workshops: More than 107 conversion centers have been equipped and certified in 37 cities countrywide. Local car manufacturers that produce CNG vehicles have equipped their existing after sale services network to service NGV products and related regular inspection. Identity information and specifications of NGV’s are being entered in audit software for tracking periodic audit and inspections.

Training: Personnel of conversion workshops, inspection centers, after sale services and CNG stations, inspectors, operators and all technical staffs who work directly with CNG, have passed related training courses and have been certified for particular activities. The general public have also been informed on safety issues through many reports, presentations and demonstrations about CNG and NGVs.

Long Term Program:
In approving the nation’s budget for the current year, Parliament gave special attention to the CNG industry and approved considerable subsidies for production of 280,000 OEM NGV’s by Iranian major car manufacturers and the conversion of 120,000 cars to CNG by available conversion workshops.
1. 20% of OEM CNG fueled vehicles are produced annually by Iran’s two biggest car manufacturers (Iran Khodro & SAIPA).
2. Conversion of 600,000 public and governmental cars to NGV.
3. 667,000 OEM CNG based vehicles and contributing a new production line of 410,000 OEM annual capacity at Iran Khodro.
4. Contributing to produce 6,000 OEM CNG based buses in 5 years.
