# Greatest volumetric heat capacity

Is there any substance with bigger volumetric heat capacity than water? According to this table water has the biggest known VHC. But I can't believe that in the 21. century we have no special material with larger VHC.

Here is a thesis that details construction and characterization of thin films with large volumetric heat capacities (some nearing $6\ MJ\cdot m^{-3}K^{-1}$):

What about the pressure? May water under greater pressure then it has at sea level accumulate more energy? –  ZAB May 16 '12 at 19:31
