Claim 0:
1. A method of producing a fuel comprising:
a) filling a pressure vessel system with biogas;
b) transporting the pressure vessel system containing the biogas from a first location to a second location; and
c) unloading the biogas transported in step (b), said unloading comprising removing the biogas from the pressure vessel system at the second location, thereby reducing a pressure of the biogas, said removing comprising:
(i) controlling a flow rate to provide a total decant time greater than 40 minutes; or
(ii) actively heating biogas contained within a pressure vessel of the pressure vessel system; or
(iii) a combination of (i) and (ii), and

d) feeding the biogas unloaded in step (c) into a biogas upgrading system, a fuel production process, or a combination thereof,
wherein step (i), or (ii), or (iii) is performed so as to reduce risk of phase change resulting from the pressure reduction and such that a temperature of the biogas within the pressure vessel system, in degrees Celsius, is greater than, (
