The desalination of seawater is increasing around the world because of water scarcity. The biggest problem is the brine that gets put back in the ocean affecting the marine life as well as the burning of fossil fuels for the generation of electricity which pollutes our atmosphere every day.
The solution is to use the brine by performing electrolysis and creating hydrogen, chlorine and sodium hydroxide. The chlorine and sodium hydroxide can be supplied to industrial companies while the hydrogen is used for fuel cells. By putting this operation in one place, we can create an effective system that produces electricity and water. This solution can be replicated across the world by working with countries that have access to the coast and in need of a sustainable way of producing electricity and water. The layout will be a desalination plant that receives seawater, the seawater is desalinated and fresh water is sent to storage tanks linking to the municipal dams or pipes. The brine gets sent to a electrolysis facility where the 3 products are produced, the hydrogen is captured and sent to the fuel cells that generate electricity where it can be connected to the grid. This solution will not only address the shortage of water and electricity but as well as have a decrease in pollution in our ocean and air. It is also in line with the SDGs of Created Share Value and Circular Economy. This would also create great private-public partnerships where we work with municipalities/governments to supply water and electricity using coastal towns/cities.
