In high-tech greenhouse operations utilizing Combined Heat and Power (CHP) or industrial boilers, daytime CO₂ dosing generates excess thermal energy. A properly stratified hot-water buffer tank ($2,000–5,000\text{ m}^3$) stores daytime waste heat at $90^\circ\text{C}$ with minimal thermocline mixing, discharging over $100\text{ MWh}$ of energy during nocturnal peak heating demands.
1. The Thermocline Richardson Number
Ri = \frac{g \times \beta \times \Delta T \times H}{u_{in}^2} > 10
Maintaining $Ri > 10$ ensures buoyant thermal stratification without convective destratification.
