SunHydrogen Inc (OTC: HYSR) is a pre-revenue clean energy company developing nanoparticle-based solar-to-hydrogen technology that splits water molecules using sunlight to produce renewable hydrogen. The company has no revenue model in operation: as of June 30, 2025, it has generated zero revenues and carries an accumulated deficit of $100,078,550, with a net loss of $8,226,307 for the fiscal year ended June 30, 2025. SunHydrogen funds operations through equity and debt capital raises rather than product sales. Its core technology, Photoelectrosynthetically Active Heterostructures (PAH), uses nanoparticles that mimic photosynthesis to perform solar-powered water electrolysis at the molecular level. The company holds two U.S. patents on PAH design and manufacturing (U.S. Patent Nos. 9,593,053B1 and 9,593,053B2, expiring November 14, 2032) and has filed additional provisional and non-provisional patent applications covering photoelectrochemical reactor designs and CdTe photovoltaic module systems. SunHydrogen competes in the renewable hydrogen production technology space against companies commercializing electrolysis powered by renewable electricity, as well as large industrial gas producers including Linde, Air Liquide, and Air Products.

Revenue model

No revenue has been generated as of the fiscal year ended June 30, 2025. The company is pre-commercial and funds operations through equity and debt capital raises, including a purchase agreement structure disclosed in filings. No product sales, licensing fees, or royalty income are reported.

Products and services

Core technology is a self-contained nanoparticle-based hydrogen generator using PAH nanoparticles that perform solar-powered water electrolysis. The company is developing a photoelectrochemical reactor with 1.92 m² modular panels, with a planned >30 m² pilot deployment (sixteen panels) at the University of Texas at Austin's Center for Electromechanics Hydrogen ProtoHub. Additional IP covers CdTe photovoltaic module systems for autonomous water electrolysis, with a non-provisional and PCT application filed August 6, 2025.

Customers and end markets

No commercial customers as of the fiscal year ended June 30, 2025. Target end markets are renewable hydrogen production for industrial and clean energy applications. The company operates at the research and pilot-deployment stage.

Value-chain role

Early-stage technology developer and IP holder in the renewable hydrogen production value chain. Holds patents on nanoparticle-based photoelectrochemical device design and manufacturing. Engages university research partners, including UT Austin's Center for Electromechanics, for pilot system deployment and performance validation.

Geographic exposure

Operations are U.S.-based. Pilot deployment planned at the University of Texas at Austin's Hydrogen ProtoHub. No international commercial operations disclosed in the fiscal year ended June 30, 2025 filing.
