Green electricity, steam and heat

Power-to-salt (PTXSALT) systems utilize the sustainable mass of molten salt as storage medium of high temperature energy in the range of up to 565º C. This can, on demand, enable green power supply which can be used for power production for daily and weekly load shifting in the electricity grid as well as for constant power supply for well-known PTX technologies such as hydrogen and methanol production. Likewise, it can be used to generate high temperature steam for various industrial processes.

High long-term reliability

Electricity from solar PV and wind turbines is stored in a two molten salt tanks. On demand, the energy is converted back to steam, to be used for the production of electricity, steam or heating. The molten salt steam generator is based on the header-coil technology, which is a fundamental building block for reliable long-term thermal storage. It is the only existing heat exchanger type with high long-term reliability and efficiency under cyclical load conditions, which is a critical point of focus for PTXSALT plants.
