Renewable natural gas Renewable natural gas Renewable Natural Gas (RNG), also known as Sustainable Natural Gas (SNG) or biomethane, is a biogas which has been upgraded to a quality similar to fossil natural gas and having a methane concentration of 90% or greater. A biogas is a gaseous form of methane obtained from biomass. By upgrading the quality to that of natural gas, it becomes possible to distribute the gas to customers via the existing gas grid within existing appliances. Renewable natural gas is a subset of synthetic natural gas or substitute natural gas (SNG). Renewable natural gas can be produced and distributed
Liquefied natural gas terminal LNG terminal whose main structure is a special ship that is moored next to the port. As of January 2014 there are operating FSRUs in Brazil, Argentina, Kuwait, Israel, the UAE, Italy, Indonesia, China and Lithuania. Liquefied natural gas terminal Liquefied natural gas terminal is a structure for liquefied natural gas to store. It can comprise special tanks, ships or even building structures. Port infrastructures and pipelines are also a part of LNG terminals. Liquefied natural gas is the form used to transport natural gas over long distances, often by sea. In most cases, LNG terminals are purpose-built ports used
