Researchers in Italy are combining PV with latent heat thermal storage (LHTM) and other renewable energy sources to maximize clean energy consumption in buildings. The 47kW PV array and LHTM ...

The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. It usually takes more energy to boil a ...

The study highlights that lakes can regulate regional energy exchange on both daily and seasonal timescales. The latent heat flux—the energy associated with evaporation—was found to reach its ...

Note the flat lines on the curve where the latent heat must be overcome to change phase. Unlike batteries or capacitors, phase change materials don’t store energy as electricity, but heat.

According to the research team, a liter of silicon material is able to store more than 1kWh of latent heat, which corresponds to the energy contained in a liter of hydrogen pressurized at 500 bar.

Heat can be stored purely physically in the form of sensible heat (temperature difference), latent heat (phase change energy) and through the use of reversible chemical reactions (reaction energy).

Over the ice-free season, 28 sensible heat pulses and 17 latent heat pulses were observed, accounting for 50.59% and 34.89% of the respective total heat exchanges at Lake Vanajavesi.
