Far from dead. They're getting fairly widespread deployment as static peak shavers for utilities. Cheaper than gas turbines, can be located anywhere and make no noise. Lots of noises being made about resurrecting the chemistry for automotive use. packaged in vacuum containers, there is very minimal heat input requirement and that is usually supplied by normal charge and discharge cycles.
