Consider a geopressurized deposit with water at a temperature of 200°C
and dissolved methane with a molar fraction of 10-5. The heat content of the water is used to generate electricity in a heat engine with one-half of the Carnot efficiency and a cold reservoir of 50°C, and the chemical energy content of the methane is used by burning the methane and generating electricity with a heat engine with an overall efficiency of 25%.
What is the energy produced by m3 of resource by each of these methods?
