For example, (x +1)*(x +1) is a term built from the constant 1, the variable x, and the binary function symbols + and *; it is part of the atomic formula (x +1)*(x +1) â¥ 0 which evaluates to true for each real-numbered value of x.
In recent weeks, the U.S. diesel fuel price has been hovering around $4.16 per gallon. LNG is selling for about $2.92 per diesel gallon equivalent, 30 percent less, according to Clean Energy Fuels' current price report, which is updated weekly.
LNG has some fixed costs above and beyond the cost of the raw natural gas. These costs are typically amortized over 20 years. The most significant of those fixed costs are: 1) Liquification plant $1.1 per Mcf +/- $0.20. 2) Shipping costs (LNG tankers and operating costs) $0.70 per Mcf +/- $0.30 depending on distance.
