The year 2026 heralds the start of the '15th Five-Year Plan' period, a pivotal phase for transforming overarching strategies into tangible initiatives. Amid this transition, technological jargon like 'green supply chain' and 'clean low-carbon hydrogen' has emerged as key areas of focus. A green supply chain represents a contemporary management framework that embeds environmental sustainability and resource efficiency across every stage of a product's lifecycle—from design and procurement to production, transportation, sales, usage, and eventual disposal. Its primary objective is to mitigate adverse environmental effects while optimizing resource utilization. Clean low-carbon hydrogen, on the other hand, denotes hydrogen generated with minimal carbon emissions through renewable energy-powered production or purification of industrial by-product hydrogen. Its carbon footprint over the entire lifecycle is substantially lower compared to hydrogen derived from conventional fossil fuels, positioning it as a vital component in accelerating the energy transition and achieving carbon neutrality. This form of hydrogen finds extensive applications in industrial deep decarbonization, transportation, and new energy sectors.
