Compared to the fossil alternative, LPG, Meva Energy’s
biomass gasi昀椀cation plant has a signi昀椀cantly lower climate impact,
see 昀椀gure 6 where different sources of LPG have been used for the
comparison.
When the biochar sequestration effects are included, the
gasi昀椀cation process gives rise to a negative emissions value, -6
g CO2-eq/kWh. This means more carbon dioxide is removed from
the atmosphere than is emitted. When only considering the impact
allocated to the biosyngas, the process shows a climate impact of
22 g CO2-eq/kWh,
The inclusion of biochar as a carbon sink allows the system
to remove more CO2 from the atmosphere than it emits, enabling
the gasi昀椀cation plant in Kisa to contribute to a carbon-negative
operation.
Conclusion
In conclusion, biomass gasi昀椀cation presents a promising
solution for decarbonization of a tissue paper mill, with substantial
economic potential. The inclusion of biochar as a byproduct further
ampli昀椀es the environmental impact of the system, providing a
viable method for carbon sequestration and supporting sustainable
agricultural practices.
The case study highlights the potential for biomass
gasi昀椀cation to serve as a key technology in the decarbonization of
industrial sectors. It demonstrates that, through innovative energy
solutions, industries can achieve not only emissions reductions
but also contribute to the broader goal of achieving the European
Union’s commitment to achieving net-zero emissions by 2050.
How do you see your energy supply in the future?
“Through our biomass gasi昀椀cation technology, we can transform locally sourced biogenic residues into two valuable
products: biogas and biochar,” explained Sara Palander, Sustainability Manager at Meva Energy.
”Biosyngas serves as a renewable energy source for industrial processes, replacing fossil fuels, while biochar, recognized
by the EU as a carbon dioxide removal (CDR) technology, enhances soil health and reduces atmospheric carbon. Combining
these bene昀椀ts is the reason we achieve such good metrics in the LCA study.”
