Understanding the Acronyms
Natural gas vehicle (NGV) fuel is made up of approximately 97% methane (ch4) . It is the same gas sourced from the public network for heating and cooking in homes. NGV fuel comes in two forms: compressed natural gas (CNG) and liquefied natural gas (LNG) . If it is made from waste, such as farm, food and household waste, as well as sewage sludge, it is known as renewable natural gas (RNG) or biomethane.
470,000: The potential number of natural-gas-powered trucks in Europe in 2030 (versus 11,500 in 2018).
NGV is not to be confused with liquefied petroleum gas (LPG) , which is a mixture of propane and butane and is stored in a liquid state, like in bottles for household use.
Today, CNG is the most widely used type of NGV fuel. It is stored at very high pressure (200 to 300 bar) in a suitable tank inside the vehicle. LNG, which is kept at a temperature of ‑161°C, has only been permitted by international regulations for use as a fuel since 2014. It requires cryogenic tanks, which are more complex and therefore more expensive, but smaller in size.
