Natural gas is generally cheaper per megajoule (MJ) than LPG. However, natural gas customers will need to pay a supply charge – a daily fee which varies between 60c and $1 for being connected to the mains gas network. LPG customers may have to pay a ‘service charge’ that covers the cost of renting gas cylinders, but this usually only This can be accomplished with a strong metal tank. To keep natural gas a liquid, it requires a room temperature and maintains a pressure of about 32,000 kPa. Household metal tanks cannot resist this pressure. Natural gas is not stored in household tanks because the symmetry of its molecule makes it hard to liquify. Here’s our quick oil and gas glossary to help you sort your coal bed methane from your LNG. Natural gas: Natural gas is a major energy source around the world, accounting for 21 per cent of the world’s energy supply in 2010. Natural gas is an odourless, colourless gas, largely formed over millions of years underground. Estimates vary, but the cost today for hydrogen produced by electrolysis is in the range of $4-6/kg, which works out to about $32-48/MMBtu. Estimates from multiple sources (e.g. the DOE here Natural gas is lighter than air. In the event of a leak it will rise and disperse in the atmosphere and not form puddles (as in petrol) or spread (as in LPG). The ignition temperature of Natural Gas is much higher than petrol making it more difficult to ignite. A high gas concentration in the air is needed to ignite CNG, not easy to achieve LPG produces more greenhouse gases than CNG. 6. CNG is light, hence if spilled, fastly disperses into the air. LPG is heavy, hence if spilled, slowly disperses into the air. 7. It is primarily used as an alternative fuel for automobiles. It is primarily used for cooking and heating our homes. 8. CNG is cheap. Both are odourless, colourless, and clean-burning fossil fuels. Propane is more energy-efficient and considered to be a green fuel, while natural gas is not. Natural gas is delivered to houses via gas pipelines. Propane is delivered in propane tanks. Lastly, propane is heavier than air, but natural gas is lighter. LPG is a mixture of gases that is produced as a residual product from oil refining. CNG / LNG are natural gas products, whereas CNG is a product for passenger cars, LNG is for trucks. It is important to know that you cannot exchange the products. A car for LPG cannot therefore refuel with CNG or vice versa. App Vay Tiền.
