Source code for A MIBL model for a Northern European negative-emission hydrogen supply chain with CCS in the North Sea
January 29, 2026 (v2)
Subject: Optimization
Keywords: CCS, Hydrogen, MIBLP, Superstructure Optimization
This study presents a mixed-integer bilinear optimization model for the cost-optimal design of a Northern European hydrogen supply chain with integrated CCS, focusing on exports from Norway to Germany and CO2 sequestration in Norway. The model is formulated as a superstructure problem and implemented in Pyomo, considering multiple locations for infrastructure nodes and transport options for hydrogen, wood chips, and CO2.

Preprint of Export of bioenergy from Norway – Hydrogen or wood chips?
January 20, 2026 (v1)
Subject: Uncategorized
Keywords: biomass gasification, compressed hydrogen shipping, eco-techno-economic analysis, hydrogen production, hydrogen supply chain, wood chip shipping
This study investigates the potential of producing hydrogen based on currently unused biomass potentials in Norway and exporting the hydrogen to the European Union. Export of hydrogen via compressed hydrogen is compared with the export of wood chips via bulk shipping and the production of hydrogen from wood chips in the respective import country. A mixed-integer linear optimization model was developed to minimize total supply chain costs of the two parallel supply chain options. Results show that shipping wood chips and producing hydrogen in the importing country is more cost-effective than producing and shipping compressed hydrogen from Norway, with levelized supply chain costs of 33.4 NOK/kgH2 versus 47.6 NOK/kgH2, respectively . This arises mainly because of significantly higher investment costs for compressed hydrogen ships and lower payload. However, hydrogen production in Norway and export via compressed hydrogen shipping result in lower overall emissions due to Norway's highe... [more]
