Global NGV knowledge hub

International Associationfor Natural GasVehicles (IANGV)

A focused international resource for natural gas mobility: compressed natural gas (CNG), liquefied natural gas (LNG), biomethane, refuelling infrastructure, safety, standards and the global NGV ecosystem.

About IANGV

Information, standards and international exchange.

The original IANGV mission described a focus for the exchange and provision of information, plus a medium for action on natural gas vehicle issues of international scope.

The International Association for Natural Gas Vehicles (IANGV) was known as an international focal point for NGV information, industry news, statistics, conference updates, technical resources and discussion around the adoption of natural gas as a vehicle fuel.

Today, the same topics remain relevant for fleets, municipalities, transport operators, policymakers and infrastructure developers evaluating CNG, LNG and renewable methane options. Natural gas vehicles use methane-rich fuel instead of gasoline or diesel, with applications ranging from light vehicles to buses, refuse trucks, delivery fleets and long-haul heavy-duty transport.

This one-page site keeps the domain useful as a clear, English-language reference on the core technologies and historic focus of IANGV.

NGV guide

What natural gas vehicles cover.

NGVs are not one single vehicle class; they are a family of fuel, storage and refuelling technologies adapted to different transport uses.

CNG

Compressed natural gas

CNG is stored at high pressure and is widely used by passenger cars, light commercial vehicles, taxis, delivery fleets and city buses where depot or corridor refuelling is available.

LNG

Liquefied natural gas

LNG is stored at cryogenic temperatures, offering higher energy density for heavy-duty and long-distance applications such as trucks, coaches and maritime-adjacent logistics.

Renewable methane

Biomethane pathway

Biomethane can be produced from biogas sources and injected into gas networks or used directly, giving existing gas mobility infrastructure a renewable fuel pathway.

Refuelling

Stations and compressors

NGV infrastructure includes compressors, storage, dispensers, fast-fill stations, time-fill depots, LNG tanks and safety systems tailored to local demand patterns.

Safety

Codes and inspection

Vehicle cylinders, workshops, fuel systems, pressure vessels and refuelling stations require clear standards, periodic inspection and trained personnel.

Fleets

Operational use cases

Urban buses, refuse collection, distribution fleets, taxis and heavy transport have historically been central NGV markets because fuel logistics can be planned at fleet scale.

Historic scope

From early web resource to sector archive.

Public web archives show IANGV as an international information site for NGV industry resources, statistics, standards and events.

1990s

International exchange

Archived IANGV pages described the association as a focus for the exchange and provision of information, and for action on NGV issues of international nature.

1998

NGV information hub

Early pages highlighted natural gas vehicles, industry news, conference information, message forums and NGV resource directories.

2000s

Statistics, standards and conferences

Later archived pages included CNG, LNG, alternative fuels, safety-and-standards bulletins, country profiles, events and technical resources.

Today

Modern relevance

NGV discussions now include renewable methane, fleet decarbonisation pathways, infrastructure economics, air-quality policy and heavy-duty transport alternatives.
