Liquid natural gas (LNG) is natural gas that has been cooled to a liquid state, making it easier to store and transport. This process reduces its volume by about 600 times, allowing large quantities to be shipped in specialized tankers. LNG is primarily composed of methane, a clean-burning fossil fuel. When LNG reaches its destination, it is converted back into gas for use in homes, power plants, and industries. This form of energy is considered more environmentally friendly compared to other fossil fuels, as it produces fewer greenhouse gas emissions when burned.
