创新绿电投资模式,推动电解铝行业脱碳
Zhong Guo Huan Jing Bao· 2025-05-19 23:21
钢铁、水泥和铝冶炼3个行业被纳入全国碳市场,三者都是高碳排产业,但排放源有所不同。钢铁和水 泥行业的碳排放主要来自生产制程(制造业中的一系列生产流程和环节),而铝冶炼行业的碳排放主要 来自电力使用。因此,铝冶炼的脱碳关键在于电力绿化,包括以绿电投资来推动绿电的开发和使用。 铝产业链的环节有铝矿开采、氧化铝生成、电解制铝、铝材加工等,其中电解环节的碳排放最多,约占 总量的70%。铝冶炼采用"冰晶石—氧化铝熔盐电解"工艺,涉及以氧化铝作为电解质,以碳素材料作为 电极。这个流程在直流电作用下发生电化学反应,氧化铝与碳阳极的还原反应产生二氧化碳,在阴极析 出铝液。以全球平均数来看,每吨铝阳极氧化过程产生的直接碳排放约为两吨CO2,其余则为电力相关 的间接碳排放。 我国电解铝的用电以传统煤电为主,各家厂商的电力碳排放虽会受到当地电网及其自备电力碳强度的影 响,但行业的平均电力相关碳强度约为12吨CO2 /吨铝,其中75%来自煤电排放。因此,煤电"换绿"是我 国电解铝脱碳的关键。 然而,绿电投资的资金金额大,回报周期长,收益不确定,开发风险高,民间资本的参与意愿不足。对 此,电解铝厂商可与电力产业共同探索可行投资模式,如 ...

Report Summary 1. Industry Investment Rating No information provided. 2. Core Viewpoints - With China's electrolytic aluminum operating capacity approaching the upper limit of 45 million tons, overseas electrolytic aluminum supply has become the main variable in global supply. The report aims to analyze the operating conditions of major overseas aluminum smelting enterprises and predict the supply trend [2][4]. - Overseas electrolytic aluminum supply is highly concentrated and mainly located in regions rich in energy resources. Currently, with sufficient energy supply and an improved aluminum market, the overall overseas electrolytic aluminum operating rate is rising. However, due to the high capacity utilization rate, the production increase from capacity expansion is limited. Existing capacity increments may come from Europe, North America, Latin America, and Africa. In terms of new capacity, the Middle East, India, and Indonesia in Southeast Asia have clear and large - scale expansion plans, which are expected to be important sources of overseas electrolytic aluminum supply growth [2][34]. 3. Company - Specific Summaries 3.1 Rusal - Rusal is a leading global aluminum company, ranking third in global aluminum smelting production in 2024 with an output of nearly 4 million tons, accounting for about 5.5% of the global total [5]. - Its smelting plants are mainly in Russia (Siberia and Ural regions) and overseas. In 2024, its existing aluminum plants had an operating capacity of 42.05 million tons with a utilization rate of 95%, leaving limited room for further improvement [6][7]. - In 2024, Asia was its largest sales market, accounting for 42.9%. Due to sanctions from Europe and the United States, it sold more aluminum ingots to Asia, especially China, where its revenue from China accounted for 30.7% in 2024, up from 6.4% in 2021 [12]. 3.2 Rio Tinto - Rio Tinto is a leading global mining and metal company and one of the top ten global aluminum producers, with a complete industrial chain from bauxite mining to electrolytic aluminum smelting [14]. - Its electrolytic aluminum plants are mainly in Australia, Canada, Iceland, New Zealand, and Oman, mostly using hydropower. In 2025, its planned production is basically the same as in 2024 (equity production of about 3.3 million tons). It is also promoting the expansion of the Arvida AP60 project in Canada, which will add 160,000 tons of capacity and is planned to be put into operation in the first half of 2026 [15][16]. 3.3 Emirates Global Aluminium (EGA) - EGA is the largest aluminum company in the Middle East and one of the top ten global electrolytic aluminum producers. In 2024, it produced 2.69 million tons of electrolytic aluminum with relatively stable production [17][20]. 3.4 Vedanta Resources - Vedanta Aluminium, a subsidiary of Vedanta Resources in India, is the largest aluminum producer in India and one of the top ten global electrolytic aluminum producers. In 2024, its total output was 2.417 million tons, a 2.4% increase from 2023. In 2025 Q1, its aluminum production remained stable. It is promoting the expansion of the Balco aluminum plant (adding about 410,000 tons of capacity), planned to be put into operation in the 2025 - 2026 fiscal year, with a long - term plan to increase annual capacity to 3 million tons [21]. 3.5 Alcoa - Alcoa is a leading global aluminum company with a wide - ranging business. In 2024, its electrolytic aluminum output was about 2.215 million tons, and in Q1 2025, it was about 564,000 tons. In 2025, with the further increase in the smelting plant operating rate, it plans to produce 2.3 - 2.5 million tons of electrolytic aluminum [22][24]. 3.6 Hydro - Hydro is the largest comprehensive aluminum group in Europe and a global leader, focusing on low - carbon hydropower aluminum. In 2024, its production at various plants showed different levels of output, with the Slovalco plant in Slovakia having no electrolytic aluminum output [25][28]. 3.7 Alba - Alba is a leading global aluminum smelting enterprise. In 2024, its output was 1.622 million tons, higher than in 2023. In Q1 2025, its output was 397,000 tons, with a slight decline. It is now aiming to increase capacity by renovating old production lines and installing new electrolytic cells [29]. 3.8 Hindalco - Hindalco is a comprehensive aluminum company in India and one of the lowest - cost aluminum producers globally. In 2024, it produced 1.327 million tons of electrolytic aluminum. It announced an investment plan in the 2024 fiscal year general meeting to expand its aluminum and copper smelting capacity, including expanding the Aditya aluminum smelting capacity by about 200,000 tons [30]. 3.9 South32 - South32 is a global mining and metal enterprise. Its electrolytic aluminum business is mainly in Brazil, South Africa, and Mozambique. In 2024, its production at different plants varied, with the Alumar plant in Brazil having an output of 118,000 tons (40% stake), the Hillside plant in South Africa having an output of 723,000 tons, and the Mozal plant in Mozambique having an output of 326,000 tons (63.7% stake) [31]. 3.10 Press Metal - Press Metal is the largest integrated aluminum producer in Southeast Asia. Its aluminum smelting plants are in Malaysia, with an annual capacity of about 1.08 million tons, all powered by hydropower, making it an important provider of low - carbon aluminum [32].

铝价为何持续下跌?
Qi Huo Ri Bao· 2025-05-09 00:24
Group 1 - After the Labor Day holiday, Shanghai aluminum futures continued to decline, with the main contract dropping to a low of 19,300 yuan/ton, driven by market uncertainty and expectations of weaker future demand [1] - Analysts indicate that the bearish sentiment in the market is partly due to the transition from the peak consumption season to a period of lower demand, as well as the impact of U.S. tariff policies on exports [1][3] - The supply of electrolytic aluminum remains at historically high levels, while downstream processing rates have begun to decline, leading to an accumulation of nearly 40,000 tons of aluminum ingot and aluminum rod inventory during the holiday [1][3] Group 2 - The average cost of electrolytic aluminum is around 16,500 yuan/ton, influenced by a significant drop in alumina prices, which may exert further downward pressure on aluminum prices amid weakening consumption expectations [3][5] - The macroeconomic environment, including potential monetary easing and the easing of U.S.-China trade tensions, could provide some support for aluminum prices, although concerns about the negative impact of tariffs on global demand persist [4][5] - The market is closely monitoring the performance of inventory and the spot market, as well as the upstream alumina prices, to gauge future trends in aluminum pricing [5]

全国碳市场扩容,要打通哪些关键堵点?
Zhong Guo Huan Jing Bao· 2025-04-27 23:22
在"双碳"目标的战略指引下,全国碳排放权交易市场(以下简称全国碳市场)作为推动绿色低碳发展的 核心政策工具,正迎来新一轮扩容。2025年3月,生态环境部正式印发《全国碳排放权交易市场覆盖钢 铁、水泥、铝冶炼行业工作方案》(以下简称《方案》),明确将钢铁、水泥、铝冶炼三大重点行业纳 入全国碳市场,覆盖温室气体排放量新增约30亿吨二氧化碳当量,占全国总量的比例从45%跃升至60% 以上。 此次扩容标志着我国碳市场建设从"单一行业试点"迈向"多行业协同治理"、从"夯基垒台"迈向"提质增 效"新阶段。同时,这也对全国碳市场机制的完善性、数据质量的可靠性、行业差异的包容性提出了更 高要求,既需要破除数据壁垒、优化制度设计,更需要激发市场活力、培育创新生态,以坚持"稳中求 进"的总基调,统筹发展与减排、整体与局部、短期与长期的关系,以真正发挥碳市场对绿色低碳发展 的战略支撑作用,为全球气候治理贡献中国智慧与中国方案。 选择钢铁、水泥、铝冶炼行业扩容势在必行 行业特性决定减排必要性。钢铁、水泥、铝冶炼是典型的高耗能、高排放行业,其碳排放强度显著高于 其他制造业领域。以钢铁行业为例,生产1吨粗钢平均排放约1.8吨二氧化碳(C ...
