The global shift toward low-carbon and sustainable energy marks a critical step in advancing decarbonization and resilient energy systems. This study presents a process-to-system modeling of a geothermal energy integrated with direct air capture (DAC) and district heating systems. The designed geothermal-DAC-district heating configuration demonstrates a technically robust and thermodynamically synergistic pathway toward carbon-negative energy systems. By effectively integrating geothermal power generation with an all-electric DAC and heat recovery system, this designed configuration advances deep decarbonization goals and aligns directly with the United Nations Sustainable Development Goals (SGDs) on affordable clean energy, sustainable cities, and climate action.
