Sometimes the projects are "open sourced." For example, the findings of "Project Foghorn," which aimed to produce a synthetic fuel from seawater, were published in two academic papers, one explaining the economics and the other the chemistry. https://x.company/projects/foghorn/
Another, "Project Malta," which aims to store energy in molten salt, was spun out into an independent company. https://www.maltainc.com/our-story
