Waterproblems find their solutions
There is a lack of adequate quantities of water of a sufficient quality.
Water scarcity is a global problem that increases in size on a daily basis. Islands and coastal areas have the possibility to desalinate seawater into fresh water. However, desalination is energy intensive. Fossil fuels have limited availability, fluctuating price and negative consequences, thus it would make sense to use renewable energy to drive the desalination process. However, reverse osmosis is designed for constant operation, while renewable energy such as the sun, wind or waves fluctuate over time.
Reverse osmosis via renewable energy
Via reverse osmosis, fresh water is produced from seawater. The energy from solar panels, wind turbines or waves is used to create an elevated salt water buffer. This allows a continuous reverse osmosis even when there is a limited energy supply. By using renewable energy the costs for the desalination decreases, and there is no other electricity source required. The solution is scalable from a few thousand liters of fresh water per day up to a million.
