China is increasingly looking towards hydrogen as a solution to decarbonize its aluminium industry in alignment with global sustainability goals. With a plan to peak carbon emissions in the aluminium sector by 2025 and support international net-zero targets by 2050, hydrogen is gaining attention for its potential in high-temperature heating, grid renewables integration, and emissions reduction. The expansion of China's national carbon trading market to include aluminium, steel, and cement is set to drive industry players towards emission reduction measures, potentially giving early adopters a competitive edge. The emphasis on clean energy substitution in China's Aluminium Industry Development Plan signifies a policy shift towards utilizing renewable electricity, with hydrogen applications being actively promoted in key production processes. The significant carbon footprint of China's aluminium sector, coupled with the majority of emissions originating from upstream processes and energy use, underscores the pressing need for decarbonization efforts. To reduce environmental impact, the industry is urged to transition to low-carbon electricity, optimize process emissions, and increase recycling rates. In the pursuit of greener electricity sources and reduced carbon intensity, China is targeting over 30% clean electricity usage in the aluminium sector by 2027, prompting investments in renewable energy and hydrogen storage infrastructure. This focus on clean energy development and emissions reduction reflects a positive sentiment towards hydrogen as a valuable tool in the shift towards sustainable practices in the aluminium industry.
