There's at least one company in the market in Australia with a metal hydride absorber system[1], and it's still nowhere near cost effective for household usage

There's at least one company in the market in Australia with a metal hydride absorber system[1], and it's still nowhere near cost effective for household usage (or really any usage IMO: I can't figure out where this would fit where batteries or something much larger like Vanadium or Iron-flow would not).
CHP is also, IMO, cheating since the retrofits to take advantage of the waste heat aren't simple or non-invasive - i.e. theoretically CHP could power hot water and air conditioning for me via heat pumps, but in practice doing any of that residentially is prohibitively expensive.

CHP is widely used in Scandinavia at least, not to mention almost all new houses here are built with water borne in-floor heating as it is much more efficient (lower circulation temperature due to more surface area for heat dissipation).
