Natural Gas and Liquefied Natural Gas Basics LNG Enables Customers to Access Natural Gas Without Direct Pipeline Infrastructure . Natural gas is abundant in North America and is used for utility, industrial, residential, commercial and transportation applications LNG is natural gas chilled LNG is not flammable as a liquid . Natural gas is primarily to ‐260 degrees Fahrenheit and quickly dissipates if released transported via pipeline where there is sufficient LNG infrastructure 101 . To reach remote areas, natural gas is liquefied (LNG), stored, and transported to end users via truck or marine vessel LNG shrinks to 1/600th Natural gas releases significantly lower the volume of natural gas emissions than other fossil fuels Source: U.S. Energy Information Administration, industry research. 5

Small‐Scale Production Offers Large Opportunity for LNG Small‐Scale LNG offers a scalable method for replacing energy sources such as petroleum and coal What is Small‐Scale LNG Production? How Does Small‐Scale LNG Reach End‐Users? Small‐scale liquefaction plants are developed to service specific markets and generally have a production capacity of less than one million gallons per day Pipeline Gas Small‐Scale LNG Plant Why Do Customers Use Small‐Scale LNG? 1 Virtual pipeline for markets that do not have access to LNG Transport traditional pipeline infrastructure or to supplement pipeline natural gas during service interruptions 2 Lower fuel and operating costs compared to competing fuels such as diesel and propane Industrial & Pipeline & Oil & Gas Mining OTR Trucks Marine Remote Power Utilities Source: Engie; Strategy & Research, GEA Group Aktiengesellschaft. 6
