I know their energy densities are crap, as are their discharge rates, but boy would I love to see nickel-iron batteries take off for large projects. HN is already about scale, scale, scale, and wow would nickel-iron benefit from that. Not exactly environmentally unfriendly, either. Another reason I think about this for infrastructure projects is, well, America is terrible about maintaining its infrastructure. It's a bit like code -- don't be surprised if that thing you banged out has to be viable for a decade more than you anticipated. And no battery tech stands up to decades of wear and tear like nickel-iron. I just know that any fancy battery stack we want to offset wind or solar will suffer from neglect as the people writing the budgets turn their eyes to shiny new things. Might as well plan for it.
