Ambient pressure storage of high-density methane in nanoporous carbon coated with graphene
Nature Energy, Published online: 23 May 2025; doi:10.1038/s41560-025-01783-zHigh-density methane storage typically requires high pressures and/or low temperatures, which can pose operational challenges. Here the authors report graphene-coated carbons that, after high-pressure charging, can store methane at high densities even at ambient external pressure.
