Water electrolysis: Direct from the sea or not to be?

Hydrogen production by electrolysis provides a sustainable energy vector, but current electrolyzers use ultrapure water. In some regions clean water is limited, but seawater is a widely available abundant resource. In a recent analysis, J. Niklas Hausmann and colleagues carry out a quantitative analysis to assess-does an economic case for direct seawater electrolysis exist?
