Distributed carbonization and centralized gasification

‌ The main reasons for producing green methanol from municipal solid waste and biomass include the following aspects: 

1. ‌ Environmental protection and energy conservation and emission reduction The production process of green methanol does not rely on fossil fuels; instead, it uses renewable resources such as biomass, carbon dioxide, and hydrogen for synthesis. This production method significantly reduces greenhouse gas emissions, helping to lower the global carbon footprint and promoting the adoption of clean energy12. By using biomass to produce green methanol, every ton of green methanol produced can save 0.77 tons of standard coal. Moreover, effectively utilizing 0.4 tons of biomass straw can reduce carbon emissions by 75%, nitrogen emissions by 15%, and sulfur and particulate matter emissions by as much as 99%34.

2. ‌ Resource utilization China boasts enormous annual output of biomass resources, among which the amount of collectible biomass straw resources is also considerable. Utilizing these resources to produce green methanol will yield significant economic and environmental benefits. For example, by harnessing 20% of China’s biomass straw resources to produce green methanol, approximately 350 million tons of green methanol could be generated each year.

3. ‌ Technological advancement In recent years, technologies for producing green methanol from biomass have made remarkable progress. For example, the Ningxia Coal Industry Olefins No. 1 Company of the National Energy Group, in collaboration with Ningxia Shenyao Technology Co., Ltd., has pioneered, for the first time across the entire industry, a pilot combustion test using continuous feed in a biomass entrained-flow gasifier. This milestone marks the successful full-load industrial operation of biomass gasification in an entrained-flow gasifier, providing valuable experience for the production of green methanol via entrained-flow gasification technology5.

4. ‌ Market demand As an integral part of green hydrogen-based energy systems, green methanol is a key component of the new energy framework and boasts enormous market potential. By establishing an integrated model for the investment, construction, and operation of green methanol businesses, we can foster comprehensive service capabilities in the “green electricity, green hydrogen, and green fuels” integration project and further expand our leading business areas.
