WebThe capacity factor for biomass is thus uncertain. No figures are given for the installed capacity and electricity production of tidal energy in the 2007 Survey of Energy Resources (WEC, 2007). Tidal energy is therefore absent from Table 1. The table clearly reflects the variable capacity factors of the power stations using the renewable sources. WebAbstract Borehole heat exchangers (BHEs) are used for transforming a rock mass into an underground heat storage. Usually, their depth does not exceed 200 m, but some extend to a depth of almost 3000 m. Underground heat storages can operate as part of heating and cooling systems, often economically.
