  text: The decarbonisation of industrial heat supply requires a realistic assessment
    of how waste heat can contribute to factory-level energy systems and where applicable,
    to external heat networks. This paper analyses temperature-specific waste heat
    potentials in automotive factories, distinguishing between vehicle assembly and
    component production. Waste heat sources are classified according to their integration
    feasibility, differentiating between directly usable heat and lower-temperature
    heat requiring upgrading via heat pumps. Using real-world operational data from
    eight automotive factories, waste heat potentials are quantified relative to site-specific
    heat demand. The results show that vehicle assembly factories exhibit relatively
    homogeneous shares of directly usable waste heat, while indirectly usable potentials
    vary strongly across sites, particularly in component manufacturing. To capture
    temporal utilisation constraints, a time-resolved case study is conducted for
    one vehicle assembly factory, combining hourly waste heat availability, internal
    heat demand and the load of an external district heating network. The dynamic
    analysis indicates that a substantial share of available waste heat can be utilised
    internally over the year, including periods of full internal heat coverage, while
    only limited surpluses remain available for external use. Overall, the findings
    underline the importance of factory-level, time-resolved analyses for identifying
    realistically utilisable waste heat shares and for supporting site-specific planning
    of waste heat integration under realistic constraints, thereby supporting the
    decarbonisation of industrial and urban thermal energy systems.
