A Process-Aware Demand Response Evaluation Framework for Hydrogen-Integrated Zero-Carbon Steel Plants Coupled with Methanol Production
Qiang Ji, Lin Cheng, Yue Zhou +4
High penetration of renewables (RES) and the retirement of thermal units aggravate flexibility scarcity in power systems. Hydrogen-based low-carbon steel production systems possess…
Demand response potential evaluation of a zero carbon hydrogen metallurgy system considering shaft furnace's flexibility
Qiang Ji, Lin Cheng, Kaidi Huang +3
The increasing penetration of intermittent renewable energy sources and the retirement of thermal units have widened the power system flexibility gap. Industrial demand response (D…
Energy-carbon comprehensive efficiency evaluation of hydrogen metallurgy system considering low-temperature waste heat recovery
Qiang Ji, Lin Cheng, Zeng Liang +4
To address the lack of energy-carbon efficiency evaluation and the underutilization of low-temperature waste heat in traditional direct reduction iron (DRI) production, this paper…
