16. Again, using sunlight to split water is not the same as using electrolysis.

If your solar panels convert about 20% of the available sunlight energy to electricity, and then your electrolysis process is 50% efficient, and then your process of converting the hydrogen back to electricity is 50% efficient, you are ending up with only about 5% of the available energy.

Eliminating a step (using sunlight directly to produce hydrogen) could be an important advance, depending on the efficiency of the process, both in terms of available energy and in terms of cost (dollars) per watt-hr.
