The use of fossil fuels for heating causes a significant share of global CO2 emissions. Geothermal energy can significantly substitute fossil fuels and aid in district cooling, resilience, and load shifting. However, system integration and scalability are currently limited. Therefore, we propose a platform-based, standardized and transferable approach covering all scales from subsurface analysis to district design and city-scale potential assessment. The development of platform-based design and operation frameworks is key to the cost-effective, wide and rapid deployment of renewable technologies with optimal integration of geothermal energy and other carbon-free resources at all scales. Specifically for Switzerland, we will integrate high-temperature borehole storage in the energy hub of the Campus Dübendorf to maximize the impact. At this Forschungscampus, we will demonstrate and validate our framework and the new storage system. Results will be reincorporated into the framework for wide deployment and technology scaling.
