Industrial hydrogen hub planning and operation with multi-scale optimisation

Résumé

Hydrogen is a chemical product and energy carrier that, if used in the right way, could help decarbonise many sectors such as transportation, electricity production, the steel industry or petroleum refining. However, hydrogen’s versatility, which a strength in terms of energy transition, makes its deployment more complex to plan. This study provides a methodology aiming to understand the evolution of a local energy system including different coupled energy vectors: natural gas, biomethane, hydrogen and electricity. A bottom-up multi-vector linear optimisation provides some elements regarding the planning and hourly operation of hydrogen production and storage infrastructures. The methodology consists in three steps. First, hydrogen demand and the technical context is modelled by defining different evolution scenarios. Then, a first optimisation at the country scale is conducted in order to define the boundary conditions for the third step, where the local hydrogen ecosystem evolution is optimised. This methodology was used to study the evolution of the industrial harbour of Fos-sur-mer in south of France. The results show that electrolysis is expected to grow, replacing existing technologies such as conventional steam methane reforming (SMR). However, depending on the context, keeping the SMR as peak production capacities can bring more flexibility into the local system and thus; improve the competitiveness of hydrogen. For the studied industrial cluster in south of France, we found an average levelised cost of hydrogen of 2.9 €/kgH2 in a reference scenario. This value can decrease to 2.5 €/kgH2 in the most flexible case with large underground storage and go up to 4 €/kgH2 in the case where SMR are banned from 2030. If space is available on a local level, then the development of dedicated renewables together with electrolysis seems to be the optimal trajectory.
