Abstract

This paper introduces the concept of distributed e-fuel hubs (DEFHs), which consist of power-to-x facilities strategically located near e-fuel demand centers. "Distributed" refers to rather small units scattered across a country close to efuel demand centers (EDCs). DEFHs valorize the local industry’s waste outputs to convert them into e-fuel, and the e-fuel synthesis by-products. The EDCs can be airports for plane refueling, ports for ship refueling, or heavy industries that require e-fuels for high-temperature processes.

This work explores the potential of DEFHs through a case study of a DEFH in Belgium synthesizing Fischer-Tropsh (FT) products (i.e. e-kerosene, e-diesel, e-naphtha) with a lime plant as the source of CO2. In this case study CO2 is captured from the plant’s flue gases using post-combustion carbon capture (PCCC). The waste heat generated during e-kerosene synthesis is valorized in a district heating network. The other e-fuel by-product considered is oxygen which is valorized on market price. Using this case study, we illustrate the appeal of our approach in terms of production cost reduction. This problem is tackled as a linear program where we optimize the asset’s capacities and operations.
