Industrial processes are usually not designed for volatility. In order to attain stability, heating of endothermal- or cooling of exothermal processes must continue round the clock – adding major cost and resource burdens to power plants. But all too often batch processes or interruptions lead to imbalances between supply and demand requiring back-up boilers to start or steam to be dumped.
Our steam to steam storage syste, fills exactly this gap by storing, time-shifting and balancing high- or medium pressure steam to make it available on demand: achieving true balance needed for greener industrial processes.
(1) Excess steam is withdrawn from steam grid to directly charge the ThermalBatteryTM
(3) The ThermalBatteryTM is discharged to steam grid (lower pressure) to supply steam on demand
Either source (1) or sink (3) is volatile and there is difference in pressure of more than 10 bars between sink and source.
Quite often quick wins can be achieved in reducing CO2 emissions on the way to net zero with consuming less energy to produce steam and efficiently balance steam supply.
Depending on client setup, commercial payback can usually be reached in less than 6 years, due to significant cost savings in fuel and carbon certificates. Sometimes additional savings from condensation purification and maintenance can also be achieved.
Harness increased security of supply with auxiliary boilers usually remaining as backup in cold standby, increasing redundancy to n-2.
