How can you make more out of your biogenic CO2 ?
Engelbert Schrapp, Principal Corporate Account Manager, Siemens Energy
INTRODUCTION:
The answer to this question, which is asked inside the Pulp & Paper Industry more and more frequently, is given by Siemens Energy
and Liquid Wind, who partnered up to use renewable energy and biomass based (biogenic) CO2 to produce eMethanol for e.g., the shipping
industry.
Methanol synthesis, based on green hydrogen and CO2 from biomass-based flue gas, raises the prospect of a carbon-neutral
industrial system. As a fuel for mobility applications and feedstock for the chemical industry, green methanol can decisively drive the
de-fossilization of the shipping industry and other industry sectors. At the same time, integrating green methanol production into existing
industrial facilities, such as pulp mills or combined heat and power plants, creates an opportunity to re-use a valuable resource like
biomass-based CO2.
As you can see in the picture above, the transformation of the
transportation industry, from one heavily dependent on fossil fuel
to an, at least, CO2 neutral industry requires all kinds of different
technologies and solutions, for example eMethanol, which can
replace ship fuel as one of the worst fossil-based fuels in use today.
The clients of the big logistic carriers are already demanding a
change, to a climate friendly alternative to transport their goods. So,
the precondition for the transformation of the shipping industry was
never better than before, even though there is still a long way to go.
The Pulp & Paper industry can play an important role by using their
biogenic CO2 emissions to support this transformation.

Production from water, green electricity, and biogenic waste
gases
eMethanol is produced by chemically combining CO2
and hydrogen. First, hydrogen is produced by an electrolyzer.
The hydrogen is converted into methanol in a reactor by catalysis
with carbon dioxide (CO2). To produce ‘green’ (i.e. carbonneutral) eMethanol, hydrogen from renewable energy is used, in
combination with biogenic CO2 .
