Abstract The basic equation for volume, heat and CO 2 flux in a porous medium which is subject to both a temperature field and molecular diffusion have been analysed with respect to the stability criteria for convectional vertical flow in a porous medium. This analysis reveals under what condition vertical convection may occur, which is important for the total storage capacity of CO 2 in aquifers.
