2. Natural Gas is clean and environmental friendly with a major obstacle - it requires a large volume at ambient conditions. As a result natural gas is generally transported at high pressure or in chilled liquid form:  Pipeline Gas – transported at different pressure levels and ambient temperature. Long distance pipelines operate at around 80 bar.  Compressed Natural Gas (CNG) – transported at 200 bar and ambient temperature.  Liquefied Natural Gas (LNG) – transported at ambient or slightly elevated pressure and -160 °C. Volume reduction is essential for batch transportation and allows for flexible handling and transportation route selection. Volume of Natural Gas at different conditions.

3.  Natural gas demand is expected to grow significantly over the next years. Natural gas contribution to the energy basket is expected to grow from 14% to 23% in 2025.  Within the next years natural gas replaces more and more coal as energy source for several reasons, e.g.:  mining constraints,  rehabilitation,  environmental issues.  Increasing demand requires development of:  new transnational pipelines and LNG terminals  accelerated utilization of domestic natural gas fields and other alternative gas sources.

4.  Various smaller gas fields exist with most of them in remote areas or offshore. Only some of them are utilized due to large distances to existing natural gas infrastructures and consumers.  1 Bill. Nm³ of gas is flared and vented each year representing 3.3% of the gross natural gas production.  Coal bed methane gas (CBM) reserves are estimated to 4.6 Trill. Nm³ which is more than four times larger than the natural gas reserves (1.1 Trill. Nm³).  Landfill gas and biogas are “new” alternatives and can be considered as renewables with neutral carbon emission.

8. Benefits of Small- and Mid-Scale LNG (IV) Lowers Market Entry Barriers  Makes it feasible for several suppliers of natural gas to compete for sales in a region, without being dependent on third-party access to pipelines.  Avoids committing to large investment funds against sales, reducing the overall financial risk, e.g. no commitment to a future pipeline has to be made upfront.  LNG based supply systems creates real options by leaving flexibility in whether and when to move to the next steps in developing the supply chain. This is particular relevant where traditional fuels are well established and the sales growth is generally slow. 8 Nov. 2010 Import TerminalSmall LNG Carrier Intermediate Storage Liquefaction Plant Truck LoadingTruck Distribution Satellite StationFuel / Filling Station

10.  Various proven liquefaction technologies are available on the market using expander or mixed refrigerant cycles.  Stranded gas is too far away from the market and/or too small to monetize otherwise. The value of the gas can be considered much lower than conventional gas sources.  For world-scale plants a high efficiency is essential whereas for small- and mid-scale plants the key to success is to compensate the negative effect of the economy of scale:  Use proven of-the-shelf equipments  Keep the process as simple as possible  Standardize and modularize plant design and construction  Optimize the balance between cost and energy efficiency Cost of liquefaction plants for various plant capacities.
