Topics

Pulp mills have as yet untapped potential as a site for power-to-X technologies. In addition to green electricity from the combustion of biomass, large quantities of biogenic carbon dioxide are also available in a pulp mill. Furthermore, the necessary infrastructure for the operation of a power-to-X plant also exists in a pulp mill (e.g. wastewater treatment, utilization of oxygen from electrolysis, ...).

Aims

This research project investigates how a power-to-X plant can be integrated into a pulp mill as efficiently and cost-optimally as possible. In addition to the energetic use of residual materials for heat and power generation, the integration of PtX concepts is being investigated as a new building block. The central element will be the production of green hydrogen by water electrolysis.
