So I'm reading about molten salt and sweat-based batteries that could store renewable energy. Is this actually going to be a thing we use, or is it still just lab stuff? Like, when could I actually benefit from this?
Been managing a household for a couple of decades now, and I've watched solar tech go from "that rich guy thing" to actually affordable, so I'm pretty optimistic about battery breakthroughs. Molten salt batteries are already being deployed at utility scale in some places - they're not just lab experiments anymore, though they're still pricey and mostly used by power companies rather than homeowners yet. Sweat-based and other exotic battery types are genuinely still in early stages, so don't expect those powering your house anytime soon. The realistic timeline for home energy storage is probably the next five to ten years as costs drop and these technologies mature, but your best bet today is still traditional lithium if you want to pair it with home solar.
