The company pursues two pathways: thin film solar modules re-engineered with a proprietary hydrogen module design, and a patented nanoparticle technology called Photoelectrosynthetically Active Heterostructures (PAH). SunHydrogen operates a pilot hydrogen production system at the University of Texas at Austin and holds partnerships with Honda R&D, CTF Solar GmbH, and others. It has not yet commercialized its technology.","people":[],"products":[{"name":"Nanoparticle-Based Tandem Semiconductor Units","type":"hardware","description":"Photoelectrosynthetic heterostructures that use sunlight to split water into hydrogen and oxygen without external power."},{"name":"Thin-Film Solar Cell-Based Hydrogen Modules","type":"hardware","description":"Hydrogen panels adapted from commercial thin-film PV modules, achieving ~9-10% solar-to-hydrogen efficiency at 1200 cm² scale."},{"name":"1.92 m² Hydrogen Reactor Module","type":"hardware","description":"Commercial-PV-sized hydrogen panel prototype demonstrated at the Hydrogen Technology Expo in Houston, Texas."},{"name":"Advanced Membrane-Free Housing Unit","type":"hardware","description":"Panel housing enabling hydrogen and oxygen gas separation without expensive ion-exchange membranes, reducing system cost."},{"name":"SunHydrogen Panel (Thin Film Pathway)","type":"hardware","description":"Re-engineered commercial thin film solar modules with proprietary hydrogen module design enabling photoelectrochemical water splitting without a separate electrolyzer."},{"name":"Photoelectrosynthetically Active Heterostructures (PAH)","type":"hardware","description":"Patented nanoparticle technology where billions of electroplated nanoparticles per square centimeter each act as self-contained water splitting units."},{"name":"Hydrogen Reactor","type":"hardware","description":"Assembly consisting of a 1.92 square meter hydrogen module installed within a housing unit for outdoor hydrogen production."}],"partnerships":[{"partner_name":"Honda R&D Co., Ltd.","partnership_type":"development","description":"Joint development agreement;
