Methods for stimulating hydrogen production from Fe(II)-bearing rocks and minerals under non-hydrothermal conditions (e.g., ≤200oC) by both increasing the rate and extent of hydrogen production and reducing the consumptive loss of hydrogen by abiotic or biotic reactions. The methods utilize a fluid (e.g., liquid) having low levels of oxidants such as oxygen, nitrates, sulfates and carbon dioxide (CO2), low levels of nutrients such as phosphate, a highly basic pH, and elevated Ca2+ or ammonium activity. In some embodiments of the methods, the fluid is free of any or all of oxidants, nitrates, sulfates, CO2, as well as the nutrient phosphate. By use of the terms "free of" and "essentially free of," what is intended is a level of no more than 1 ppm per oxidant.
