Publishable summary

Liquefied Natural Gas (LNG) is a strategic, and in the case of long distances, a more economical alternative for pipeline gas. It is also used to transport natural gas from and to locations where no pipeline infrastructure exists. After regasification of the liquid form, the natural gas is transported to the main users: power plants, industry and households. Recently the use of LNG as a cleaner transport fuel has been added to the list of important applications.

Need for the project
In comparison with other commodities like natural gas or gasoline the total uncertainty of measured energy is high for LNG and has been estimated to be up to 1 %. The current lack of direct traceability to the SI also leads to the delayed introduction of new measurement methods in the LNG business. Therefore, a sound metrological framework is an indispensable element for the development of LNG as transport fuel, which is one of the pillars of the EU clean fuel strategy.

Scientific and technical objectives
The aims of the JRP are to further develop the metrological framework for LNG, to contribute to a reduction of the measurement uncertainty of LNG custody transfer by a factor two (starting from 1 %) and to enable the development of LNG as a clean transport fuel.
