: Purpose of Review : Cities are crucial for an effective energy transition, yet national transition exercises often overlook local urban conditions. This paper reviews the assessment of hydrogen integration in urban energy system models and the use of Geographical Information Systems (GIS) to facilitate high spatial resolution modelling. Recent Findings: Embedded GIS frameworks can unmask local conditions crucial for energy transition planning, providing valuable insights to support informed decision-making. We found a gap in holistic modelling of the hydrogen supply chain and sector coupling. Furthermore, most studies lack future cost projections, and GIS is often underutilised. We also detected a general lack of transparency and low temporal resolution. Summary: This review assesses urban hydrogen integration, highlighting how geospatial approaches are used to addresses the lack of local information in recent energy system modelling, Future research should enhance GIS use, integrate sector coupling, and improve transparency and temporal resolution to better understand the optimal integration of hydrogen.

Understanding current and future residential energy demand is crucial for energy system planning and demand-side management. In this database, we generate high-resolution (1-minute) residential multienergy load profiles for Auckland and Christchurch (New Zealand) and Oldenburg and Karlsruhe (Germany). We use resLoadSIM, a stochastic bottom-up tool, to simulate household electricity and heating demand by aggregating individual appliance consumption based on occupant behaviour and statistical data. Based on projected electrification trends, we simulate future energy demand scenarios, by integrating electric vehicle (EV) adoption and electrification of space heating. The resulting dataset provides valuable insights into how residential load profiles may evolve. The data can be used by researchers and urban planners as inputs into energy capacity expansion planning models, grid stability analyses, and demand-side management strategies.
