I usually see people saying the batteries will catch fire and the toxic gasses will kill everyone within 3 miles. Like many NIMBY complaints, they are barely based in reality and blown away out of proportion.

I’ve seen a dozen or so grid scale battery projects local to me in the NE. The majority are hung up in litigation with local NIMBY opposition. The scale of the opposition always surprises me, I can’t help but wonder how much is grassroots vs anti-renewable lobby.
