As I complete my Personal MBA in the Circular Economy, I am exploring and building my inventory of practical ideas that could or have been commercially applied. Ideas that target Circular Systems, Energy, Water, Waste and Wealth – ideas that focus on using the waste of one process as a valuable input to another.
Ships are not part of the Paris Climate Change agreement. Cruise and cargo ships are massive CO2 emitters. This is madness given their impact.
There is a solution. This has been proven, it is not theoretical.
- We use solar panels to extract hydrogen from sea water.
- This hydrogen is stored – a battery – a battery much lighter than lithium, which would cause the boat to sink, of course. Hydrogen is the lightest element and this increases the energy storage by a factor of 6.
- We then use the hydrogen to generate electricity through a fuel cell.
- The by-product. Fresh drinking water. There is no need for desalination!
Could this same principle be used for cities? Create a buoy out in the ocean?
