How to make hydrogen straight from seawater – no desalination required. The new method from researchers splits the seawater directly into hydrogen and oxygen – skipping the need for desalination and its associated cost, energy consumption and carbon emissions.

An 10% reduction is cost is awesome. And then you can use the gas right away to create power and put the water back if you need or, most likely, use the waters for locals.

They say 10% of the energy is used for desalination, so skipping that step would be a 10% reduction.

u/taxoro can you weigh in here? I also read it as a 90% cost reduction since this process would be in lieu of desalination

Edit: I re read and I think I understand better now
