Superpermeation allows for hydrogen fluxes through metal foil membranes at rates orders of magnitude higher than pressure driven permeation. This process occurs only for hydrogen isotopes, meaning it is hydrogen-selective, and it can work against a pressure gradient, implying pumping capabilities. These characteristics allow for using superpermeation as the base process for a very efficient, selective separation of hydrogen from other gases.

在清洁和氧覆盖的表面上原子氢与 N​​b 和 V 相互作用的从头算模拟

超渗透允许氢气以比压力驱动渗透高几个数量级的速率穿过金属箔膜。该过程仅针对氢同位素发生，这意味着它具有氢选择性，并且可以逆压力梯度工作，这意味着泵送能力。这些特性允许使用超渗透作为基本过程，以非常有效地、选择性地将氢气与其他气体分离。
