Summary

As energy systems move towards lower carbon emissions and higher shares of renewable energy, stronger connections between electricity, heat, hydrogen, and other energy carriers become increasingly important. Hydrogen is expected to play an important role in this transition, especially in sectors that are difficult to electrify directly. At the same time, hydrogen related processes, including production, storage, transport, and conversion, are often associated with heat release and heat demand. My research studies how these heat flows can be understood and integrated in a systematic way, and how their role changes when they are considered in different energy-system contexts.

The research is organized at three levels. The first is the hydrogen storage technology level, which focuses on heat integration within specific hydrogen storage options. The second is the hydrogen supply chain level, which considers the broader chain from renewable energy supply to hydrogen production, storage, transport, and end use. The third is the sector coupled energy system level, which studies hydrogen in interaction with electricity, heat, storage, and transport infrastructure across sectors and locations. Across these levels, I combine process modelling, techno economic assessment, and capacity expansion and operation optimization.
