Hydrogen Utilization in Pulp Mills for Enhanced Sector Coupling Based on Biogenic CO2

Sub-project: Path Analysis, System Simulation and Life Cycle Assessment

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

In the project, a path study is used to analyze how hydrogen from electrolysis can be used. It is not only about the plant-internal use but also about products which can be sold. By means of a system simulation, the material and energetic integration of selected power-to-X paths in the pulp mill will be analyzed and economically evaluated. Furthermore, the combined purification of methanol from pulp cooking and from a power-to-methanol plant is investigated experimentally. Finally, the simulated production paths are evaluated with a life cycle assessment based on the ecological footprint.
