Transportation sector contributes significantly to increased emission of greenhouse gases and local environmental pollution (e.g. smoke in large cities) by the combustion of large amounts of fossil fuels. For the energy transition, adsorbed natural gas technology (ANG) is a promising technology as it can directly replace gasoline by biomethane with lower CO2 emissions and in an existing infrastructure. To achieve required energy density, methane need to be stored in gas tanks at very high pressures (200 bars). Alternatively, it can be stored as an adsorbed phase on a porous solid at relatively low pressure (3.5-4 MPa) and at ambient temperature, in adsorbed natural gas technology (ANG). The low pressure allows using lightweight, inexpensive, conformable fuel tanks, single stage compressors, and facilitates decentralized refueling at lower costs. This project aims to investigate the adsorption of natural gas on hierarchical porous materials at low pressure and at ambient temperature to lower the cost of methane storage. For this purpose metal-organic frameworks with ultrahigh surface areas of several 1000 m2/g will be investigated for methane storage after structuring into macroscopic shape by advanced processing techniques, such as electrospinning of MOF nanofibers and in-situ growth.
