Green hydrogen at scale
Commercial Scale
The Western Australia facility produces 100 tons of green hydrogen daily using 500 megawatts of solar power. Production costs have reached $3 per kilogram, approaching competitiveness with gray hydrogen.
Export Market
Japan and South Korea have signed long-term offtake agreements, viewing Australian green hydrogen as essential to their decarbonization strategies. Export facilities are under construction.
Applications
Green hydrogen enables decarbonization of steel, shipping, and aviation—sectors difficult to electrify directly. The Australian project proves commercial viability of this critical technology.
