    <title language="eng">Designing a Fully Renewable Urban Energy System: The Meaning of Sector Coupling and Hydrogen</title>
    <abstract language="eng">This study is the first in a two-part series focused on establishing a fully renewable and energy-autonomous supply system for a small city. Part 1 explores comprehensive energy modelling, while Part 2 introduces an innovative graphical representation that clarifies the operational management strategies of the city's energy hub.&#13;
In this initial part, we conduct an exhaustive analysis of the city's energy needs across all sectors, including residential and commercial electricity demand, heating, and mobility, which provides an almost complete depiction of the urban energy landscape. The city is divided into two clusters: Cluster 1 features decentralized heating primarily through air-to-water heat pumps for low density residential buildings, while Cluster 2 employs a district heating grid for multi-family-buildings.&#13;
Our analysis indicates that approximately 9 kW of wind and solar power capacity per inhabitant is necessary to entirely meet energy demands through renewable resources, with wind power contributing the majority.&#13;
Hydrogen storage plays a crucial role in mitigating seasonal energy fluctuations by leveraging existing capacities within Germany. The study finds that utilizing waste heat from hydrogen production in district heating networks is more efficient, highlighting the advantages of smaller, community-scale hydrogen power plants over larger facilities that lack thermal integration. Furthermore, the study concludes that additional battery and thermal storages are unnecessary when hydrogen storage is implemented. An investment of 11.5 k€ per capita in energy converter facilities is required.</abstract>

    <title language="eng">A Methodological Approach to Analyze Operation Strategies in a 100% Renewable Energy System with Multiple Energy Outputs in an Urban Environment</title>
    <abstract language="eng">This study presents a method and graphical representation for optimizing the operational strategy of urban energy systems to simultaneously meet electricity and heat demands. Building on Part 1, "Designing a Fully Renewable Urban Energy System: The Meaning of Sector Coupling and Hydrogen," this paper addresses the previously open question of effectively operating a complex structure of multiple energy converters. By introducing a two-dimensional merit order principle, the study systematically prioritizes the use of energy converters based on their efficiency and role in balancing heat, electricity, and hydrogen demands. Visualized through a graphical representation, this approach offers an intuitive understanding of how different energy converters interact to meet demand states, elucidating why specific converters are employed under varying conditions. By providing valuable insights into cross-sectoral energy integration, this methodology serves as both a planning tool and educational resource. It highlights the optimal deployment of specific technologies, with applicability extending to other coupled energy systems, such as heating and cooling systems in diverse contexts.</abstract>
