Dec 8, 2020 “Wall Street has begun trading water as a commodity, like gold or oil. The country’s first water market launched on the Chicago Mercantile Exchange this week with $1.1 billion in contracts tied to water prices in California, Bloomberg News reported.” “Two billion people now live in nations plagued by water problems, and almost two-thirds of the world could face water shortages in just four years” -, Tim McCourt, global head of equity index and alternative investment products at CME.
The World Water Council map on beside shows many areas of the world are in crisis due water shortage: many more are on the brink. All continents are affected. Clean water is abundant, transport costs are the problem.
Trials have shown that well over 2/3 of the cost of delivering water was for towing by tugs. Large tankers would need an expensive inner coating to carry potable water, would burn expensive fossil fuels and emit tonnes of CO2 and noxious gases.
Here is a real opening for a low-cost low-emissions system. Desalination is very expensive, massively so for potable water, and very environment unfriendly
Transport costs are the barrier, so enter the Aquatug, a Jospa tug towing a large rubber or elastomer bag of water, the size of a football field. A similar bag, the “Spragg” bag, has been towed successfully off the US west coast. It is not practical to tow such a bag faster than the Jospa Tug can. A tanker would move quicker but at higher capital, conversion and operating costs, and probable infrastructural capex, for potable water.
