The Planets around Tau Ceti may be fairly volcanic

If it is a "hot ice giant" (or, rather, a "hot ice dwarf"), then it might be similar to a miniature HydroJovian; if a waterworld, then it might even be of the BathyPelagic type, because of its (relatively) low mass. The low metallicity of the primary star (~28% relative to Sol) indicates most, if not all, planets will be rocky terrestrials rather than gas giants, so the likelihood of e being a gas dwarf is not high. A large terrestrial or a waterworld seem the most probable choices, in that order. As far as warmth is concerned, quantities of liquid water will persist on the surface at (Bond) albedos between 0.278 and 0.343, assuming Earth-like atmospheric pressures and constituents.
