For storage, cost per unit energy ($/J or $/kWh) is a useful unit, but because the molar specific heat of virtually all materials is nearly constant, $/mol can also be used. This is because specific heat is predominantly attributed to the amount of energy contained in each atom''s three degrees of freedom (i.e., x, y, and z) of motion.

A possible way for seasonal storage of solar energy will be the thermochemical heat storage (THS) based on vapour adsorption–desorption of zeolites, silica gels and salt hydrates (Table 3). Due to the nature of these materials, as long as they kept hygro-thermally insulated in dry form they are able to store heat independent of the …

Figure 5.3.4 demonstrates a system where dissipative flow is apparent. In this case the steady-state fluid is flowing horizontally in a pipe with uniform area. Thus, there is no change in gravitational or kinetic energy-density from point 1 to point 2 in the figure. Equation 5.3.9 simplified to ΔP = − IR .
