"Iron-air batteries have an exceptionally long lifespan, estimated at over 10,000 charge/discharge cycles, which corresponds to a service life of approximately
20 to 30 years." So notably better than other battery tech. Heavy and inefficient are the downsides. Safe, cheap and long lasting are the upsides. So its good for grid batteries. Maybe even great, I'm not versed enough in the power industry to say.
