Abstract:

This project was conceived as an extension of a pre-existing optimization tool determining the optimal design of a multi-energy system. The tool determines the optimal selection, sizing and operation of a set of technologies to satisfy the hydrogen demand of an end-user while minimizing the total costs or CO2 emissions of the system [1]. The main goal is to include the spatial network perspective, with the aim of designing an optimal supply chain at a national scale for the use of hydrogen in the mobility sector. Concerning hydrogen production, a comparative assessment of production technologies for blue and green hydrogen, e.g. Steam Methane Reforming and electrolysis, has been carried out. Furthermore, the trade-off between two different types of biomass as energy source was investigated for two processes: biomass gasification with ‘dry’ biomass and biogas reforming with ‘wet’ biomass. They were selected because they are both very interesting for integrated hydrogen production with CCS towards a negative CO2 emissions supply-chain. Three economically competitive networks were analyzed for hydrogen transport: namely railway, pipeline and trucks. Similarly, dry biomass distribution was also considered for the hydrogen production via gasification. Several model parameters and assumption have been investigated through sensitivity analysis, namely the impact of energy losses, the size effect on the investment cost and the effect on the minimum and maximum energy carried by the different networks.
