I hold no position in Nikola. Positives include them working in an area with potential large upsides, specifically trying to develop the use of Hydrogen where it's a good fit today, in long haul trucking. Future great places for it include shipping, sporadic power generation storage (wind and solar), etc. Batteries improve steadily, but so far nothing proven scalable and affordable doesn't involve significant amounts of limited lithium, meaning alternatives to battery systems are worth pursuing.
