LPG (Liquefied Petroleum Gas) is a hydrocarbon gas that exists in a liquefied form. LPG is a colourless, low carbon and highly efficient fuel. Supplied in two main forms, propane (C3H8) and butane (C₄H₁₀), LPG has a range of uses – from providing fuel for leisure parks, crop-drying, BBQs, heating homes and much more.

LPG boils at a low temperature and to avoid it evaporating due to its low boiling point, it is typically stored in pressurised steel vessels such as gas bottles or bulk LPG tanks.
