A fuel cell vehicle ( FCV) or fuel cell electric vehicle ( FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels ( petrol or petrodiesel ). The term also refers to any technology (e.g. electric cars, hybrid electric vehicles, solar-powered vehicles) powering an engine that does not solely involve petroleum. [citation needed]
Compressed natural gas ( CNG) is a fuel gas mainly composed of methane (CH 4 ), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical shapes.
There were 6,700 fuel stations selling autogas in 2014, supplying about 500,000 registered gas-fuelled cars (1.1 per cent of all cars in Germany). mylpg.eu lists 7.240 stations in 2016. In addition to filling stations, numerous suppliers of industrial gas run dedicated autogas stations on their premises. Most filling pumps use the ACME adapter ...
The time to fill a CNG tank varies greatly depending on the station. Home refuels typically fill at about 1 kg/h (0.4 GGE/h). At gas stations, where the pressure is greatly higher, it is possible to refill a 25 kg (10 GGE) tank in 5–10 minutes. Also, because of the lower energy density, the CNG range is lower compared to LNG.
One way is to compress the gas to very high levels. Hydrogen fuel cell cars like the Toyota Mirai contain Kevlar-armored tanks that store hydrogen at 700 times the pressure of the Earth’s ...
Two sets, or tiers, of emission standards for light-duty vehicles in the United States were defined as a result of the Clean Air Act Amendments of 1990. The Tier I standard was adopted in 1991 and was phased in from 1994 to 1997. Tier II standards were phased in from 2004 to 2009. Within the Tier II ranking, there is a subranking ranging from ...
Cascade filling system. A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. [ 1][ 2] In some applications, each of the large cylinders is filled by a compressor, otherwise they may be filled remotely and replaced when the pressure is too low for effective ...
