Renewables->electrolysis->hydrogen->ammonia could be a viable energy storage and transport system, regardless of efficiency, as long as it can be made cheap enough. Not all energy demand is easy to run a wire to, and those demands will be willing to pay the cost of inefficiency as long as the absolute price is bearable.
