Energy consumption and GHG emission for regional aluminum industry: A case study of Henan province, China

摘要

Aluminum industry is a typical energy-intensive and emission-intensive industry. Henan's aluminum output occupies the first for many years until 2013 in the whole country. We analyzed 18 applicable to aluminum smelting process and 8 energy-efficiency technologies to alumina production process. The Conservation Supply Curve (CSC) is used in this paper. It is an analytical tool which selects the economically feasible technologies. Three scenarios are simulated. Under the BAU, S1 and S2 scenario, the energy consumption of the aluminum industry will decrease by 19%, 25%, and 29% compared to 2014 level respectively. The emission mitigation of GHG in SI and S2 scenario are 3.2 Mt CO2e and 5.4 Mt CO2e, compared to BAU scenario in 2030. In addition, sensitivity analysis is conducted. Finally, some policy implications are proposed.
