Desalination energy and cost
Estimate energy demand and energy cost for a desalination plant of a given capacity.
Result
Specific energy consumption
3.50kWh/m³
Daily energy demand
350.0MWh/day
Continuous power requirement
14.58MW
Annual energy cost
15.33£ million/year
Energy cost per m³
0.420£/m³
Against the thermodynamic minimum
3.5× the ~1 kWh/m³ physical floor
Method
Daily energy = capacity × specific energy consumption. Annual cost = daily energy × 365 × electricity price. The thermodynamic minimum for seawater is shown for comparison.
