尽管含水层地下储氢是大规模储氢的最有前景的选择，但导致指进的不稳定流动会增加损失，从而限制经济运行。例如，由于地下气泡表面积的增加，气体进入地下水的溶解速度加快。讨论了手指的尺寸，并解释了实验室模型的实验，以表明地下气泡是如何发展的：最初是圆形的气泡生长出手指，这些手指分裂并分叉形成树状结构。缓冲气体将是地下储氢的主要费用。也许可以使用氢气以外的气体作为垫子；然而，指法将再次提供限制。
Although underground storage in aquifers appears to be the most promising option for large-scale storage of hydrogen, unstable flow which leads to fingering will present limitations to economical operation because it increases losses. For example, the rate of solution of gas into ground water is accelerated due to the increase in surface area of the underground gas bubble. The dimensions of fingers are discussed and experiments with laboratory models are interpreted to indicate how an underground gas bubble develops: an initially circular gas bubble grows fingers which split and branch out forming a tree-like structure. Cushion gas will be a major expense of underground hydrogen storage. It may be possible to use a gas other than hydrogen as the cushion; however, fingering will again provide limitations.
