Green Methanol Introduction
Green methanol is a carbon-neutral cornerstone energy based on carbon dioxide and green hydrogen or by-product hydrogen. The production process has negative carbon emissions, and water and carbon dioxide are discharged after combustion, with zero net emissions.It does not use fossil fuels such as oil, so it is also called "non-fossil fuel". This method of production is called "green chemistry".
In China, coal to methanol production capacity has reached 90 million tons/year. The production process of green methanol has negative carbon emissions and zero net emissions, which is sustainable.
At the same time, methanol fuel has been more mature application cases in the fields of vehicle, Marine, high-power methanol generator,methanol fuel cell power generation.
Definition
Green methanol is a renewable energy source, mainly made from biomass, waste and renewable resources, Compared with traditional oil and coal sources, it is more environmentally friendly and sustainable.
Production method
Green methanol production usually adopts biological fermentation technology, which ferments crops, wastes, forestry residues, etc., as raw materials, and then makes it through a series of chemical reactions and refining processes.
Feature
Green methanol has the advantages of high energy density, renewable and low carbon, and can also be used as fuel in automobiles, ships, aircraft and other fields.
Typical Pathway to Methanol
Various Routes Spanning Across Renewables and Fossil Fuel
It can be produced in two ways using renewable energy and renewable raw materials.
Renewable methanol：Biological methanol produced from biomas. Potential sustainable biomass feedstocks include: forestry and agricultural waste and by-products, biogas from landfills, sewage, municipal solid waste (MSW) and black liquor from pulp and paper industries.
Green methanol is produced using CO2 captured from renewable resources (bioenergy from carbon capture and storage [BECCS] and direct air capture [DAC]) and green hydrogen (hydrogen produced from renewable energy generation).
Description
Methanol process
The main steps of biomass gasification gas to produce methanol：
Gasification：
In conditions of high temperature and lack of oxygen, biomass is converted into syngas which mainly CO, CO2 and H2, among which CO and H2 are the key raw materials for the synthesis of methanol.
Gas purification:
Remove impurities such as sulfide, nitrogen oxide and particulate matter in the synthesis gas to ensure the smooth progress of the catalytic reaction.
Methanol synthesis :
In the presence of a catalyst , the purified syngas is synthesized into methanol, and appropriate conditions are controlled to increase the output and purity of methanol.
Product separation storage:
The methanol produced is separated and stored for use as fuel or chemical feedstock.

Green methanol marketing studies
Methanol upstream and downstream chains
The potential market requires billions of tons of methanol per year, so in addition to existing methanol applications, renewable green methanol can also replace most petroleum hydrocarbons and petrochemicals directly or as methanol derivatives.For example, the production of plastics and aromatics (BTX) from renewable methanol could be significantly scaled up. This contributes to the transition to a sustainable circular green economy, where renewable methanol is specifically positioned as a future-oriented chemical feedstock and fuel.
Methanol downstream application
The largest downstream market for green methanol is for chemical production. In 2020, nearly 78% of methanol in China is used for chemical synthesis, the main synthetic products are olefin, formaldehyde, acetic acid, MTBE and diformaldehyde, and 18% of methanol is used as fuel combustion.
