Methanefueled

Methanefueled refers to systems, vehicles, or engines that utilize methane as their primary source of fuel. Methane, the main component of natural gas, is a potent greenhouse gas and a hydrocarbon with the chemical formula CH4. When used as a fuel, it can be combusted to produce energy, typically in internal combustion engines or turbines.

Vehicles powered by methane are often referred to as natural gas vehicles (NGVs). These can operate on either compressed natural gas (CNG), where the gas is stored at high pressure, or liquefied natural gas (LNG), where the gas is cooled to a liquid state for greater energy density. Methanefueled engines are generally considered to be cleaner burning than gasoline or diesel engines, producing fewer particulate matter and nitrogen oxides. However, methane itself is a potent greenhouse gas, and unburned methane escaping into the atmosphere contributes to climate change.

The use of methane as fuel is driven by several factors, including its relative abundance and lower cost compared to fossil fuels in some regions, and the potential for reduced tailpipe emissions. Infrastructure for refueling methanefueled vehicles, however, is less widespread than for conventional fuels. Applications extend beyond transportation to include power generation and industrial processes.
