Claim 0:
1. A process for producing gas and generating power or electricity, comprising:
producing hydrocarbon gas from an underground reservoir, a produced hydrocarbon gas being at a first temperature;
heating a heat exchange medium via concentrated solar power to increase a temperature of the heat exchange medium;
heating the produced hydrocarbon gas, via indirect heat exchange with the heat exchange medium, to a second temperature, producing a heated produced hydrocarbon gas and a cooled heat exchange medium; and
expanding the heated produced hydrocarbon gas across an energy conversion device to convert energy contained in the gas to another form of energy,
wherein:
the indirect heat exchange is conducted via an indirect heat exchange system,
the expanding produces a low-pressure produced hydrocarbon gas, and
the low-pressure produced hydrocarbon gas is prevented from further getting into the indirect heat exchange system.
