A different kind of source water

Offering producers the solution they need to fulfill the promise of green hydrogen by delivering high-purity, electrolyzer-ready water with the lowest energy demand, fully powered by renewable energy.

ProtiumSource results from collaboration, combining H+E’s decades of expertise in ultrapure water with innovation from The Gradiant Labs.

Lowest Total Life Cycle Costs

Our high-purity source water exceeds the specified requirements for all electrolyzer systems, extending their usable life and reducing CAPEX, OPEX, and Total Life Cycle Costs.

Feedwater-Agnostic

ProtiumSource outputs a guaranteed, high purity, electrolyzer-ready water from any feedwater. This includes seawater, brackish water, and treated wastewater, making it highly adaptable to operating environments with poor-quality input water.

Industry-Leading Efficiency

Gradiant's award-winning RO Infinity with CFRO technology delivers best-in-class performance with the lowest energy, reducing overall capital requirements for renewable energy infrastructure.

Zero Liquid Discharge

Brine management challenges are mitigated by recycling all water with the option to produce zero or minimal liquid discharge.

Offers Producers compelling benefits

Lower OPEX 

From lower maintenance demands with reduced CIP and minimal consumables

Zero CAPEX  

Option for Gradiant to build, own, and operate the complete electrolyzer-ready water system

Supercharged with SmartOps AI

For immediate savings in efficiency and operating cost
