Re-inventing methanol for a fossil-free future

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.
