Green alcohol fuels (mainly referring to green alcohols, with green methanol and green ethanol as the core) are the fastest-growing clean energy category under the dual-carbon development background. The core application areas that have been implemented or are planned are as follows:
1. Transportation Sector (Core Growth Driver)
This is currently the largest demand scenario for green alcohols, covering three sub-sectors with high emissions and difficulty in decarbonization:
Ocean Shipping: This is currently the most core application direction for green methanol. The shipping industry is a major source of global carbon emissions. The International Maritime Organization has clearly required the shipping industry to halve its carbon emissions by 2050. Green alcohols can directly replace traditional marine fuel oils; existing ship engines can be modified for use. It is currently the most mature and feasible solution for decarbonization in shipping, and leading shipping companies have already placed bulk orders for methanol-powered ships.
Aviation Industry: Green alcohol can be processed into sustainable aviation fuel (SAF), directly replacing traditional aviation kerosene. China's first and the world's largest green aviation fuel industrial demonstration project was launched in May 2026. The 300,000-ton green hydrogen alcohol aviation fuel project in Jixi, Heilongjiang Province, is expected to be operational by the end of 2027, directly producing green aviation fuel to replace high-carbon aviation fuels.
Land Heavy-Duty Transportation: In the long-haul heavy-duty truck sector, pure electric heavy-duty trucks have significant shortcomings in range and refueling. The alcohol-hydrogen power technology based on green alcohol production is mature. The Yuancheng Xinghan H alcohol-hydrogen electric tractor has achieved a range of 1522 kilometers, reducing fuel costs by 30% compared to traditional heavy-duty trucks, making it an important solution for decarbonizing heavy-duty transportation.
2. Energy Storage and Peak Shaving:
Green alcohol is currently a highly cost-effective green hydrogen storage and transportation carrier. In regions with abundant renewable energy, green hydrogen can be produced by electrolyzing water during off-peak hours, and then combined with carbon dioxide to synthesize green alcohol for storage. During peak hours, the green alcohol is reformed to produce hydrogen, which is then used to generate electricity via fuel cells and fed into the grid. This reduces wind and solar curtailment, improves renewable energy utilization, and solves the problems of high transportation costs and difficult storage of green hydrogen, significantly enhancing the flexibility of the power system.
3. Chemical Production:
Green alcohol itself is an important green chemical raw material. Methanol is the most basic organic chemical raw material. Green alcohol can be used to produce hundreds of basic chemical products such as formaldehyde, dimethyl ether, ethylene, propylene, pesticides, and pharmaceuticals. Compared to alcohols derived from traditional fossil fuels, green alcohol can achieve carbon reduction across the entire industrial chain, meeting the market demand for "low-carbon products" from downstream chemical companies. Furthermore, green alcohol can be used to produce biodegradable bioplastics, replacing traditional non-biodegradable plastics and reducing plastic pollution.
4. Distributed Energy Sector:
Fuel cell distributed energy systems based on hydrogen production from green alcohol reforming can simultaneously supply electricity and heat to buildings and industrial parks. This reduces reliance on centralized power grids, improves energy efficiency, and achieves zero carbon emissions, making it suitable for independent energy supply in industrial parks and remote areas.
