Abstract

Geologic hydrogen could be a low-carbon primary energy resource; however, the magnitude of Earth’s subsurface endowment has not yet been assessed. Knowledge of the occurrence and behavior of natural hydrogen on Earth has been combined with information from geologic analogs to construct a mass balance model to predict the resource potential. Given the associated uncertainty, stochastic model results predict a wide range of values for the potential in-place hydrogen resource [10 3 to 10 10 million metric tons (Mt)] with the most probable value of ~5.6 × 10 6 Mt. Although most of this hydrogen is likely to be impractical to recover, a small fraction (e.g., 1 × 10 5 Mt) would supply the projected hydrogen needed to reach net-zero carbon emissions for ~200 years. This amount of hydrogen contains more energy (~1.4 × 10 16 MJ) than all proven natural gas reserves on Earth (~8.4 × 10 15 MJ). Study results demonstrate that further research into understanding the potential for geologic hydrogen resources is merited.
全球地质氢资源模型预测
地质氢可能是一种低碳的初级能源资源;然而,地球地下蕴藏量的大小尚未得到评估。我们将地球上天然氢的存在和行为知识与地质类似物的信息相结合,构建了一个质量平衡模型来预测资源潜力。考虑到相关的不确定性,随机模型的结果预测了潜在的就地氢资源[10.3 到 10.10 百万公吨 (Mt)]的广泛数值范围,其中最有可能的数值为 ~5.6 × 10.6 百万公吨。虽然其中大部分氢的回收可能不切实际,但一小部分(例如 1 × 10.5 百万公吨)将提供达到净碳零排放约 200 年所需的预计氢量。这一数量的氢所包含的能量(约 1.4 × 10 16 兆焦耳)比地球上所有已探明的天然气储量(约 8.4 × 10 15 兆焦耳)还要多。研究结果表明,有必要进一步研究了解地质氢资源的潜力。
