Innovative Green Hydrogen Solutions
Discover how Onestone Holdings harnesses cutting-edge vertical wind turbines on ships combined with AI and satellite data to produce and transport sustainable green hydrogen, revolutionizing renewable energy.
Onestone Holdings Generates Abundant Electricity at Scale on Its Ships
Onestone’s specialized wind turbines can scale to an incredible size that is entirely impossible on land. These offshore turbines can surpass the size of the biggest classic land-based wind turbines by double. The system is designed to produce electricity for the entire planet at an affordable and sustainable rate.
Ship Design
Stable and Fast Movement: Onestone’s ship design incorporates proprietary vessel telemetry and AI-optimized operations to ensure the platforms are stable in open-ocean marine environments while remaining mobile and relocatable to high-wind zones.
Massive Wind Turbines: The vessels carry specialized, large-scale vertical-axis wind turbines designed to harvest persistent open-ocean winds with a 95%+ capacity factor.
Onboard Green Hydrogen Facilities & Storage: The ship integrates a complete green hydrogen production facility—converting electricity via electrolysis using ocean humidity—alongside cryogenic storage systems to maintain hydrogen at extreme cold temperatures without using fossil fuels.
Onboard Green Liquid Hydrogen Production Facility
Avoiding Long-Distance Power Loss: While land-based green hydrogen production requires transmitting electricity over hundreds of miles through high-voltage cables—resulting in substantial power loss during long-distance transmission—Onestone’s ship-based facility integrates electricity generation directly with hydrogen production.
Maximum Efficiency: By producing green liquid hydrogen immediately at the source of generation on the ship, the system achieves the highest possible efficiency from raw electricity production straight to storable and transportable green liquid fuel.
Onboard Green Liquid Hydrogen Production Facility
Dehumidification: Onestone’s vessels utilize advanced dehumidification technology—a thermal-based purification process that replicates natural condensation cycles using unlimited surrounding humidity.
Zero Land and Freshwater Impact: By generating its own pure water directly on board for green hydrogen electrolysis, the system places zero strain on municipal freshwater supplies or drought-prone land regions.
Maximum Environmental Integrity: This self-contained marine water generation makes Onestone’s green liquid hydrogen production one of the most environmentally friendly, sustainable, and truly independent energy solutions on Earth.
Advanced Onboard Electrolysis
Direct Water Feed: The ultra-pure water generated on board via the Dehumidification system is fed directly into the vessel’s advanced electrolyzes.
Powered by Offshore Wind: Driven by the high-capacity electricity produced by the ship’s massive onboard wind turbines, the electrolysis units efficiently split the water molecules into green hydrogen and oxygen.
A Closed, Self-Sustained Loop: By combining on-site dehumidification and direct electrolysis right at sea, the ship creates a seamless, self-contained green fuel production cycle that operates completely independently of land-based resources.
Onboard Liquefaction and Cryogenic Storage
Direct Liquefaction: Immediately following electrolysis, the newly produced green hydrogen is routed through an advanced onboard liquefaction system, cooling the gas down to its liquid state for efficient transport and handling.
Cryogenic Storage Integration: The liquid hydrogen is safely stored in specialized, highly insulated cryogenic containment tanks built directly into the vessel’s hull.
Ready for Global Delivery: This integrated storage allows Onestone’s ships to transport clean fuel directly to heavy industry, steel manufacturers, and AI data centers anywhere in the world without relying on complex onshore pipeline infrastructure.
