Powering the sustainable energy transition
Green methanol is rapidly emerging as a cornerstone solution in the global energy transition, offering a renewable and sustainable alternative to conventional fossil-based methanol. As a versatile liquid energy carrier, green methanol is projected to experience substantial growth over the next two decades, creating viable decarbonization pathways across multiple industries.
This carbon-neutral chemical delivers exceptional versatility with applications spanning numerous sectors. Green methanol significantly reduces emissions in maritime transportation while providing clean fuel alternatives for road vehicles. It also plays a crucial role in power generation by supporting renewable energy integration and serves as a sustainable feedstock for countless products in chemical manufacturing.
With over 50 years of expertise in methanol synthesis, Clariant leads the renewable methanol revolution through innovative catalysts designed specifically for the energy transition. Our catalysts are already operating in commercial-scale green methanol projects worldwide.
Types of green methanol: bio-methanol and e-methanol
Green methanol represents a revolutionary advancement in sustainable fuel technology, available in two distinct forms: bio-methanol and e-methanol. Both variants deliver substantial carbon reduction benefits compared to conventional fossil-based methanol, though they utilize different production methods and feedstocks to achieve their environmental advantages.
Bio-Methanol production
Bio-methanol is produced from renewable biomass sources, offering a sustainable alternative to fossil-based methanol through a sophisticated multi-stage process.
Feedstock preparation
Bio-methanol can be produced from various biomass sources, including agricultural residues, forestry by-products, biogas from landfills, sewage, municipal solid waste (MSW), and black liquor from the pulp and paper industry.
Gasification
The biomass undergoes gasification, converting it into synthesis gas (syngas), a mixture primarily consisting of hydrogen, carbon monoxide, and carbon dioxide.
Purification of synthesis gas
The purification is a crucial part of the process because biomass and waste sources contain numerous non-typical impurities and poisons (such as heavy metals, As, S, Cl, and others), which can deactivate the methanol synthesis catalyst. Clariant has extensive experience and a wide portfolio of purification catalysts and adsorbents, including the ActiSorb series.

Methanol synthesis
The syngas is then converted into methanol using specialized catalysts. Clariant's MegaMax catalyst technology demonstrates effectiveness well-suited for biomass-to-methanol projects, providing enhanced stability and tolerance to system fluctuations inherent in green methanol production.
Clariant's comprehensive catalyst portfolio includes the ActiSorb series for syngas purification and the MegaMax series for methanol synthesis. These catalysts have been selected for several bio-methanol lighthouse projects across China and Europe, validating their commercial viability and performance excellence.
E-Methanol production
E-methanol represents an innovative pathway to sustainable methanol production, harnessing renewable electricity and captured carbon dioxide.
Green hydrogen production
The production process begins with green hydrogen production, where renewable electricity powers water electrolysis to produce green hydrogen with minimal environmental impact—a critical component that distinguishes e-methanol from conventional production methods.
Carbon Dioxide Capture
CO₂ is captured either from industrial point sources, bioenergy with carbon capture and storage (BECCS), or directly from the air through direct air capture (DAC) technologies. The process continues with CO₂ capture from industrial point sources, bioenergy with carbon capture and storage (BECCS), or directly from the atmosphere through direct air capture (DAC) technologies.
Methanol synthesis
The captured CO₂ and green hydrogen are then combined in a catalytic reactor to produce methanol. Clariant’s MegaMax catalysts has demonstrated exceptional performance in e-methanol applications, exhibiting excellent activity and stability despite the challenging conditions of CO₂-to-methanol conversion. This technological advancement enables more efficient and economical production of this promising renewable fuel.
Both bio-methanol and e-methanol pathways offer viable solutions for industries seeking to reduce carbon emissions while maintaining operational efficiency, with the optimal choice depending on regional resources, infrastructure, and specific sustainability goals.
