Natural gas vehicle gas has the highest energy/carbon ratio of any fossil fuel, and thus produces less carbon dioxide per unit of energy. The major difficulty in the use of natural gas is transportation. Natural gas pipelines are economical and common on land and across medium-length stretches of water (like Langeled, Interconnector and Trans-Mediterranean Pipeline), but are impractical across large oceans. Liquefied natural gas (LNG) tanker ships, railway tankers, and tank trucks are also used. CNG is typically stored in steel or composite containers at high pressure (3000 to 4000 psi, or 205 to 275 bar). These containers are not typically temperature controlled,
Center for the Study of Carbon Dioxide and Global Change Center for the Study of Carbon Dioxide and Global Change The Center for the Study of Carbon Dioxide and Global Change is a 501(c)(3) non-profit organization based in Tempe, Arizona. The Center produces a weekly online science newsletter called "COScience". The Center was founded and is run by Craig D. Idso, along with Sherwood B. Idso, his father, and Keith E. Idso, his brother. They came from backgrounds in agriculture and climate. According to the Idsos, they became involved in the global warming controversy through their study of earth's temperature sensitivity to radiative perturbations and plant responses to elevated CO
