Third life for coal-fired power plants
Third life for coal-fired power plants
Heat storage power plants use electricity from renewable sources to heat a heat
a heat storage tank with circulating molten salt. When surplus electricity is available
is available, the salt is heated by an electric heater and temporarily stored in a "hot" tank at over 400°C
temporarily stored in a "hot" tank. For subsequent electricity generation, the hot salt is fed into the
pumped back into the "cold" tank at over 200°C via the power plant's steam generator and is then
is then available for a further charging cycle. The possibility of co-firing with
biogas, synthesis gas from power-to-gas or natural gas guarantees reliable performance at all times.
