- UK spin-off Hychor is hacking the green hydrogen bottleneck with a direct-seawater electrolyzer. No desalination, no freshwater drain, just pure energy density. By leveraging seawater’s natural conductivity and sidestepping corrosive chlorine, this off-grid tech turns the ocean into a fuel source. It’s the physical layer of AI’s future: scalable, clean power for rockets and heavy industry. While batteries hit their limits, Hychor’s system promises cost-effective, on-site production. This isn’t just chemistry; it’s infrastructure engineering for a post-fossil world. Robots need power; factories need scale. Hychor delivers both, turning saltwater into the backbone of sustainable automation.
