Saudi Arabia Signs 27 Green Hydrogen Deals at Innovation Days

A packed conference hall in Riyadh just became ground zero for the next phase of the clean energy revolution.

ACWA Power wrapped up Innovation Days 2026 last week by signing 27 strategic partnerships focused on green hydrogen technology. The event was so oversubscribed that organizers announced it will expand internationally, with Shanghai hosting the next gathering.

Green hydrogen, made by splitting water using renewable electricity, could replace fossil fuels in industries like shipping and aviation. But the technology remains expensive. These new partnerships target that exact problem.

Danish company Topsoe will provide ammonia technology for the massive Yanbu Green Hydrogen Project. California startup SunGreenH2 is testing electrolyzers that skip precious metals entirely, potentially cutting costs dramatically while maintaining performance.

Other deals tackle efficiency from fresh angles. Advanced Ionics is piloting a medium-temperature system that uses less energy than conventional electrolyzers. Shanghai-based H-Ray developed a method that slashes precious metal use without sacrificing output.

The partnerships extend beyond equipment. German energy company EnBW and Japanese trading house ITOCHU both joined as co-developers and investors in a project targeting 2.5 million tonnes of green ammonia annually.

One partnership stands out for sheer ambition. ACWA will explore receiving power beamed from space-based solar collectors to fuel desalination and hydrogen production. If successful, the company would become one of the first commercial recipients of orbital solar energy.

Universities from MIT to Tsinghua contributed research expertise. Saudi AI company HUMAIN participated across sessions on digital operations and pilot testing, showing how artificial intelligence could optimize hydrogen production.

"Innovation Days has evolved from a meeting to a launching pad," said Thomas Altmann, ACWA's EVP of Innovation. The 27 partnerships include clear goals and dedicated resources rather than vague intentions.

The Ripple Effect

Saudi Arabia is positioning itself as more than an oil exporter. Under Vision 2030, the kingdom is building infrastructure to become a testing ground for integrated clean energy systems at commercial scale.

The sold-out event drew government bodies, research institutions, and investors across energy, water, hydrogen, AI, and storage sectors. That cross-pollination matters because green hydrogen doesn't exist in isolation. It requires renewable power, water desalination in arid regions, and storage solutions.

By combining these elements and attracting global technology partners, Saudi Arabia is creating an ecosystem where innovations can jump from lab prototype to industrial deployment faster than in fragmented markets.

The Shanghai expansion signals that this model could be replicated elsewhere. China leads global electrolyzer manufacturing, while Saudi Arabia has renewable energy resources and ambitious decarbonization targets.

These 27 partnerships won't solve climate change alone, but they represent real money and real commitments moving green hydrogen closer to affordability.
