storage density of natural gas. CNG is typically stored in steel or composite containers at high pressure (205 to 275 bars (2,970 to 3,990 psi)). These containers are not typically temperature controlled but are allowed to stay at local ambient temperature. There are many standards for CNG cylinders. The most popular one is ISO 11439.
Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure.It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 bar), usually in cylindrical or spherical shapes.
[1] Compressed natural gas (CNG), for example, is a gas rather than a liquid. It can be measured by its volume in standard cubic feet (ft 3 ) at atmospheric conditions , by its weight in pounds (lb), or by its energy content in joules (J), British thermal units (BTU), or kilowatt-hours (kW·h).
Production licences for the Rough field were given in 1964, and gas was first brought ashore to Easington gas processing terminal in 1975. In 1980, British Gas Corporation (which became British Gas plc in 1986 following privatisation) purchased the Rough field with one-third of reserves depleted, with the intention of converting the field into a gas storage facility to manage seasonal trends ...

[5] [6] It specializes in health and nutrition related products, including vitamins, supplements, minerals, herbs, sports nutrition, diet, and energy products.
A standard 20-MPa, 5-L steel bottle has a mass of 7.5 kg, and a superior one 5 kg. High-tensile-strength fibers such as carbon fiber or Kevlar can weigh below 2 kg in this size, consistent with the legal safety codes. One cubic meter of air at 20 °C has a mass of 1.204 kg at standard temperature and pressure. [54]
A compressor map is a chart which shows the performance of a turbomachinery compressor.This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor.
