Bioenergy is used as primary fuel for Thermal Storage Power Plants in order to guarantee firm power capacity at any time just on demand in order to close the residual load gaps of the power sector. PV and energy storage integrated to TSPP save as much biofuel as possible in order to reduce the pressure on the limited available bioenergy resources.
However, the enormous change in the volume of the storage materials is a problem and hence is not used in general. The thermal energy stored by latent heat can be expressed as (2) Q = m · L where m is the mass (kg), L is the specific latent heat (kJ.kg −1). 2.2.1.
