Outdoor seating areas, often found in urban environments, can indirectly affect underground calcium-air storage systems through environmental interactions. These storage systems rely on chemical reactions involving calcium carbonate and air to store energy or regulate air quality.

The presence of outdoor seating increases human activity and surface-level disturbances, which may alter soil composition and air circulation patterns. This can impact the efficiency of underground calcium-air reactions by introducing contaminants or changing moisture levels. Additionally, seating materials (e.g., concrete or metal) may leach substances that interact with calcium compounds underground.

Research suggests that prolonged exposure to elevated CO2 levels from crowded seating areas could accelerate calcium carbonate dissolution in storage systems. However, well-designed outdoor spaces with proper ventilation may mitigate these effects by maintaining stable air exchange rates. Understanding these dynamics is crucial for urban planners integrating energy storage solutions beneath public spaces.
