That's nonsense. Hydrogen is just another engery storage technology, and an inefficient one.
Batteries are more efficient, and charge/discharge comes from same device, at a very high power rate. But $100/kwh or even $50/kwh storage cost is higher than $1/kwh cost of H2. H2 being transportable and siteable anywhere with water/electricity access, makes it much more useful than alternate storage technologies.
The battery problem is that it will be sized too big to charge on some days, and too small to fully discharge on others. The high storage costs mean an economic requirement to have at least/close to full daily charge/discharge cycles.
The sellable/transportable property of H2 means producing an unlimited amount in one place, and distributing it as needed. H2 has many different applications than fuel/electricity conversion as well. If we ever make too much, we can shoot stuff into space with it.
