Transcelestial develops shoebox-sized CENTAURI devices that send lasers to one another to form a fiber-like wireless network. The system is designed to avoid underground cables and radio-frequency licensing issues, enabling a lower cost per bit. CENTAURI units have been deployed in South Asian and Southeast Asian markets, and the company demonstrated its technology delivering 5G connectivity at the University of Technology Sydney. Transcelestial plans regional expansion across Indonesia, India, the Philippines, Malaysia, Singapore and the United States, and is working under stealth with a few ISPs and a major enterprise cloud and data center company on the U.S. West Coast. The startup is also developing a low-earth-orbit constellation to deploy its wireless fiber optics from orbit. Its Terabit Factory has capacity to manufacture up to 2,400 CENTAURI devices annually, and recent funding will be used in part to harden that facility against supply-chain uncertainties.

SunGreenH2 has developed a proprietary nanostructured, alloy-based electrode for electrolysis that forms a 3D sponge-like surface, more than doubling current density and hydrogen output while reducing precious-metal use by about 30x. The electrode increases active surface area and, the company says, is compatible with virtually all modern electrolyzers. To address nanostructure fragility, SunGreenH2 uses a "sacrificing catalyst" that corrodes in a way that preserves or enhances the main catalyst's lifespan. Initially the company intends to sell the electrode component separately; next year it plans to partner with system integrators to produce whole electrolysis stacks and later pursue more end-to-end solutions with larger companies. SunGreenH2 also plans to apply its platform to related green-transition materials, including PTLs and bipolar plates for fuel cells, electrodes for batteries, and photoelectrodes for direct solar-to-hydrogen panels. The company has raised $2 million in seed funding to set up its first manufacturing facilities in Melbourne to meet demand from early, confidential partners in the EU, U.S., Canada, Japan and Singapore.
