Research of high-pressure reactions in the earth by engineers and geologists have led to many to conclude that since carbon and hydrogen are massively present in the earth, hydrocarbons will exist within it in a variety of forms. Over time, they get trapped in geologic zones that are favorable for storing or absorbing the carbon. Movement of earth masses combined with very high pressure and temperatures make the earth a huge chemical reactor. The low-level nuclear reaction can ensure that the motion and resulting reactions are continuous, and perhaps hydrocarbons can be considered a renewable resource.
