steel research international, Volume 91, Issue 11, November 2020., 2020 A novel process for extraction, storage, and utilization of off‐gas waste heat is discussed. Key difference to other concepts is the application of entrained flow Ca(OH)2 dehydration. Waste heat exchangers are avoided. Balancing of power‐off times for the reference plant requires just small heat storage tanks of 6.5 m3. In total, a net power generation
