Deploying affordable and sustainable energy storage devices is one of the major pillars for changing the current energy systems. Natural gas (NG)/bio-methane storage for vehicle transportation is an existing technology where the gas is pressurized up to 250 bar. One possibility to reduce the compression and infrastructure costs of new installations is to use tanks filled with porous solids that can selectively adsorb and release methane. This is the so-called Adsorbed Natural Gas (ANG) concept, where pressure of storage is reduced to 30–60 bar while the energy density per tank volume is maintained.

吸附天然气装置工程数学模型的充分性与复杂性

部署负担得起且可持续的能源存储设备是改变当前能源系统的主要支柱之一。用于车辆运输的天然气 (NG)/生物甲烷存储是一项现有技术，其中气体加压至 250 巴。降低新装置的压缩和基础设施成本的一种可能性是使用充满多孔固体的储罐，这些固体可以选择性地吸附和释放甲烷。这就是所谓的吸附天然气 (ANG) 概念，其中存储压力降低至 30-60 bar，同时保持每罐体积的能量密度。
