基于电力绿证下的铝行业降碳新思路

Green Energy Certificate--Provides New Ideas for Carbon Reduction in Aluminum Industry

铝行业是中国有色金属工业碳排放量最高的领域,2020年全产业链(采矿、冶炼、加工)碳排放总量超过5.6×10^(8)t,约在中国有色金属工业中占比80%,其中排放量最高的铝电解环节(间接排放)排放量达到3.85×10^(8)t,约占铝行业总排放量的68.8%。中国铝行业实现碳减排,使用绿色电力是最为关键的一环。近年来,中国电解铝行业通过向清洁能源地区转移产能,全行业能源结构有了明显的改善,随着电力市场改革的不断推进,“绿证”的推广为铝行业进一步改善能源结构提供了新的思路。

In 2020,the total carbon emissions of the whole aluminium industrial chain(mining,smelting and fabricating)reached 560 million tons,accounting for 80%of the total emissions of the non-ferrous metal industry,which is the highest sector.Among them,indirect emissions from power consumption in aluminum electrolysis were about 385 million tons,accounting for 68.8%of the total emissions of the aluminum industry.It’s the biggest emitter.The use of green electricity is the key to reducing carbon emissions in China’s aluminum industry.In recent years,China’s primary aluminum industry has significantly improved the energy structure of the whole industry by transferring capacity to clean energy areas.With the continuous advancement of the power market reform,the promotion of“green energy certificate”provides a new idea for the aluminum industry to further improve the energy structure.
