Would be interesting to know what percentage of desalination costs comes down to energy, and what percentage to fixed costs for building and then maintaining the equipment.
- _rpd 9y agoThis paper[0] has capex and opex costs for three types of desalination technology - multistage flashing (MSF), multi-effect distillation (MED) and reverse osmosis (RO). The lowest costs are for reverse osmosis and are $113 million capex, $19 million annual opex, for a 68000 cubic meters per day plant (which is apparently a defacto standard size) with an expected lifetime of 25 years.
