I'm excited about this - we need to invest in different energy storage solutions; as promising as batteries are they may not be the global optimum for all things as the common woo tells us. For long haul trucking, battery mass eats substantially into payload. And while batteries are getting much cheaper, they aren't getting much lighter (cue the "but structural batteries" woo here). Hydrogen is an incredibly energy dense fuel and can be used in a wide variety of applications, but trucking may be the driver that pushes hydrogen economics and infrastructure towards being a viable part of our power storage and distribution system. Once something drives hydrogen at scale, it becomes possible to think about long term (seasonal) energy storage, electrification of long-haul flight, and replacement of fossil fuel for industrial process heat - all vital for driving emissions to zero.
