Pumping for Desalination
Approximately 97.5% of the Earth's water is seawater, and no more than about 2.5% is fresh water, and most fresh water is held in glaciers, icebergs, and underground reservoirs. Water that can be used easily by humans, such as that in rivers and lakes, accounts for just 0.1% of the total. Meanwhile, the global population topped 6 billion in 2000 and is expected to reach 8 billion by 2025, of which 3.5 billion are likely to face water shortages. An important component of the solution to this growing problem is desalination. However, vast amounts of energy are required to supply fresh water for ever growing populations. VIVACE can supply the pumping power (and power for other demands) in a renewable manner without emitting greenhouse gases or other pollutants.
As shown in the graph, the average annual growth in desalination capacity over the past 20 years is approximately two million cubic meters per day.
