I agree battery will be better in the future. But it doesn't follow that battery is better investment today. On civil engineering project going poorly, I think that's the problem of poor project management, but I guess sometimes technical solution to management problem makes sense. I note pumped storage gets built routinely within time and budget without any fuss all over the world.
