Why would anyone care at all about portability for grid storage? This makes no sense.

Why would anyone favor lithium ion for grid storage? Makes no sense. So if someone is comparing their product to something that makes no sense, they aren’t making sense.

Are they confused, or just lying?

I would pretty much agree except that lithium ion keeps being sold as a grid storage solution for some reason. But yes they should obviously be showing superiority to lead acid, pumped hydro, etc. as well.
