Sounds like it might. Depending on what the membranes are made of, it would be a sustainable, renewable form of energy. I'd say it's worth more research dollars and hope they'll continue working on it.

As the researchers themselves state in the original Reuters article, if every river in the world were dammed with osmotic membranes for this process the energy collected would meet about 20% of existing energy demand.  Destroying all estruaries and driving migratory fish to extinction is too high a price.
