H2 is increasingly regarded as a decarbonized solution for the increasing energy demand. However, due to its low density, H2 cannot be easily compressed, and there is a need for materials that can store large amounts of H2. Here we tested H2 adsorption capacity of micro-polyethylene (MicroPE) – a significant environmental pollutant - at 1–70 bar and 30 °C. H2 adsorption capacity increased with increasing the adsorption pressure (from 0.06 mol/kg at 17.21 bar to 0.20 mol/kg at 68.11 bar for raw MicroPE). MicroPE activated with aqueous NaOH significantly changed H2 adsorption under the same operating conditions. H2 adsorption increased …

Hydrogen is a clean fuel that can potentially completely decarbonize the energy supply chain and mitigate global warming. Hydrogen – a highly volatile gas – however, needs to be separated from CO2 during H2 production, and also from cushion gas in H2 geo-storage projects; in addition, large-scale H2 storage is a key obstacle. We thus tested and chemically upgraded common sub-bituminous coal as a material for H2-CO2 separation and H2 storage. The coal adsorbed significant amounts of H2 and CO2 and demonstrated an excellent H2-CO2 separation efficiency if chemically modified. The work presented here thus provides fundamental data required for …
