ABSTRACT:
An embodiment is an apparatus for generating a driver gas, for recovering fluid from the Earth's subsurface. The apparatus includes a fuel reformer, adapted to react a fuel with water to produce carbon dioxide gas and hydrogen gas; a compressor, adapted to compress a portion of the carbon dioxide gas and a portion of the hydrogen gas; a gas injection unit, adapted to inject the portion of the carbon dioxide gas and the portion of the hydrogen gas compressed by the compressor, into a subsurface reservoir; a gas capture unit, adapted to capture a portion of the carbon dioxide gas and the hydrogen gas, that emerges from the subsurface reservoir; and a control module capable of using subsurface data to regulate operation of the gas injection unit. The apparatus may also include a power generator adapted to utilize a portion of the hydrogen gas to generate power, hence producing electricity without greenhouse gas emissions.
