LNG metrology—Measurement support for LNG as a transport fuel

The use of LNG as fuel has generated much interest in the global transportation sector due to two main drivers—the environment and cost. First, LNG emits virtually no sulfur oxides (SOX), low nitrogen oxides (NOX) and particulate matter, and significantly less carbon dioxide (CO2) per unit of energy released than do oil-derived liquid fuels. This can reduce the compliance cost imposed by the use of traditional liquid fuels. Second, interest in LNG is also driven by lower prices and by gas marketers’ need to create new markets for now-abundant gas supplies. The lower retail price of natural gas in recent years is a strong driver for LNG penetration in commercial transport.1 Within the EU, th
