Gradiant unveils advanced end-to-end solution for electrolyzer-ready water
Gradiant, a global solutions provider for advanced water and wastewater treatment, has announced the launch of ProtiumSource, an end-to-end solution that delivers high-purity, electrolyzer-ready water with the lowest energy demand, fully powered by renewable energy.
ProtiumSource is the result of collaboration, combining the recently acquired H+E Group’s decades of ultrapure water expertise with innovation from The Gradiant Labs.
ProtiumSource offers several key features: it is feedwater-agnostic, delivering guaranteed high-purity, electrolyzer-ready water from any feedwater input, including seawater, brackish water, and treated wastewater, making it highly adaptable to operating environments with limited access to high-quality input water. Additionally, it mitigates the challenge of managing brine by recycling all water with the option to produce zero or minimal liquid discharge. The system also claims to offer industry-leading efficiency, utilizing Gradiant’s award-winning RO Infinity with CFRO technology to deliver what the company describes as best-in-class performance with the lowest energy demand, reducing overall capital requirements for renewable energy infrastructure. Furthermore, ProtiumSource is said to ensure the lowest total life cycle costs by providing high-purity source water that exceeds the specified requirements for all electrolyzer systems, extending their usable life and reducing CAPEX, OPEX, and total life cycle costs.
ProtiumSource employs water treatment technologies in a fully integrated, balanced three-phase system that Gradiant tailors to the throughput needs of any green hydrogen production plant. The first step involves water purification, leveraging Gradiant’s Pretreatment, Selective Contaminant Extraction, and RO Infinity technologies to remove a complete range of inorganic and organic contaminants from any feedwater. The second step focuses on electrolyzer-ready source water production, utilizing H+E’s ultrapure water expertise and experience in IX, EDI, and UV technologies to yield electrolyzer-ready water that exceeds industry specifications. The final step incorporates an integrated brine management system for zero liquid discharge, using Gradiant’s RO Infinity with CFRO technology to reclaim water from brine at the pretreatment and high-purity stages.
“Gradiant believes in the promise of a hydrogen-based economy and understands that producing the best possible electrolyzer-ready water is critical for green hydrogen to achieve its full potential,” said Prakash Govindan, COO of Gradiant. “With the introduction of ProtiumSource, we are removing a major hurdle to making green-hydrogen a fully renewable energy source.”
Siva Kumar Kota, Gradiant’s Head of Technology, added: “Our ProtiumSource solution for green hydrogen producers is testimony to the adaptability of Gradiant’s core technologies to solve key societal challenges. Our patented technology portfolio enables Gradiant to quickly develop revolutionary solutions, like ProtiumSource, to meet the water needs of green hydrogen producers.”
