I've looked a bit more in depth, and it turns out what Electriq Global does is much more interesting and much more plausible than what's described in the article. It's a very poor quality article. What they do (or at the very least, claim to do) is create a fuel via H2 + KBO2 -> KBH4, apparently in the form of a powder that's much easier to handle and transport than hydrogen itself (no leaks, no heavy pressure vessels needed). In the vehicle (or where ever you need electric energy) they use the reverse reaction: powder in, H2 and KBO2 out. The H2 can then be used in a fuel cell to generate electricity. I don't know if they envision some recycling system to get the KBO2 back to the factory. If that turns out to work, efficiently, it could be a promising technology.
