We’re developing an ultra-efficient catalysis to mass-produce green methanol —
enabling the shipping and chemical industry to save gigatons of CO2


Fossil-free produced green methanol is key to decarbonizing the shipping and chemical industry.

In shipping today, green methanol is the most tangible carbon-neutral fuel alternative to oil. Replacing oil as shipping fuel will save several gigatons of CO2 every year. Green methanol can also replace oil, gas, and coal as a non-fossil carbon source in the chemical industry, resulting in similar CO2 savings.


To make green methanol — in sufficient amounts and at a competitive price — we have to fundamentally re-invent its production.

Large-scale methanol production today relies on a century-old, maxed-out, high-emission catalysis process. This process is so energy-intensive that it is only economically viable in large-scale plants using cheap gas and coal. It is ill-suited for a more decentralized, flexible production needed to tap into green feedstock sources.

Replacing gas and coal with non-fossil feedstocks without changing the production process would make green methanol expensive and economically unattractive.

for HIGH-PURITY green methanol

100% fossil free. Competitively priced. Decentralized production.

Using quantum-chemical simulations and lab experiments, we invented a new ultra-efficient catalysis for green methanol.

It enables the mass-production of high-purity green methanol at a competitive price — using decentralized, non-fossil feedstock, low pressures, and low temperatures at any plant scale.

Combined with a cutting-edge, containerized design the C1-reactor makes decentralized green methanol production possible almost anywhere.

The ecological impact of our technology is huge: It enables methanol production that locks the carbon used in a continuous cycle instead of adding it into the atmosphere. This empowers industries using green methanol to reach net-zero emissions and save gigatons of CO2.

Existing non-fossil carbon sources — like waste biomass or, in the future, carbon captured from the atmosphere — are converted into syngas

Even if the resulting methanol is burned, it does not add additional CO2 into the atmosphere

Our flexible, decentralized reactor uses our patented C1-Catalysis to synthesize methanol at a lower pressure and heat

The resulting high-purity green methanol is competitively priced and ready for industrial use

Re-inventing methanol for a fossil-free future

Carbon One Team The C1 Team

The challenge that lies in front of us is enormous but not insurmountable. However, we need to move fast. In 2021, mankind emitted 36 billion tons of CO2 into the atmosphere.

To secure a future for our children, we have to break our dependency on oil, gas, and coal to cut carbon emissions to net zero by 2050.
Green methanol in the heart of a circular carbon economy can help us achieve this by providing hard-to-abate industries a way to defossilize.  

That is why we are re-inventing every production step from the atomic scale up to the industrial scale. For our planet. And for our children.
