I never said a single word about transportation. For urban cores, batteries are obviously quite viable today. What I am concerned about is energy storage for power grids or microgrids. Do you want to claim that hydrogen and ammonia can't work for this use case either, and that there is nothing viable? Implying that the most sustainable option is to just continue using fossils fuels. What I think is that there a ways to make both hydrogen and ammonia and other options very viable not only for grid storage but also for transportation. What's holding it back is a lack of critical thinking. This is because most people's views are dictated by social circumstances and then they subconsciously find ways to rationalize them. In other words, it's hard to get people on board with solving new problems related to using different energy sources, and so executives will invent reasons it can't work. What sort of fuel do you think makes sense to pursue for long term (months) energy storage?
