DNV validates Electric Hydrogen’s HYPRPlant as industry-standard, power-dense turnkey electrolyzer after multi-year testing and factory audit

(IN BRIEF) DNV has completed a comprehensive review of Electric Hydrogen’s second-generation HYPRPlant electrolyzer, confirming compliance with industry standards in process design, safety and manufacturing. The turnkey PEM system—available in 75, 100 and 120 MW variants—achieves high power density, cutting stack counts and simplifying deployment. DNV evaluated proprietary stack technology, power electronics, controls and warranty terms; audited lab and pilot data from 2022–2025; observed a 1/10th‑scale commercial stack at the Pioneer Plant in San Jose; and inspected the Devens, MA factory’s lean quality systems. The review verified that HYPRPlant maintains rated efficiency, pressure and purity while collecting degradation data. Richard S. Barnes of DNV called the work vital for bankability and hailed the plant’s power density and flexibility. CEO Raffi Garabedian said the validation affirms Electric Hydrogen’s mission to build large, low‑cost electrolyzer plants. DNV, active in over 100 countries, provides assurance across the energy value chain and supports accelerated decarbonization.

(PRESS RELEASE) BÆRUM, 23-Jul-2025 — /EuropaWire/ — DNV, the independent energy expert and assurance provider, has wrapped up a full-spectrum technical review of Electric Hydrogen’s second-generation HYPRPlant electrolyzer system, confirming that its process design, safety approach and manufacturing practices align with current industry standards. The pre‑engineered, turnkey platform leverages high‑current‑density proton‑exchange membrane (PEM) stacks to split water into hydrogen and oxygen, trimming front‑end engineering effort and on-site installation time while enabling scalable, utility‑grade green hydrogen production.

DNV’s assessment drilled into Electric Hydrogen’s proprietary PEM stack technology, power electronics, overall plant architecture, monitoring and controls, plus the standard product warranty and commercial assurances around the core technology. The review focused on the Gen‑2 HYPRPlant, which introduces fluid optimization and improved stack isolation. Offered in 75 MW, 100 MW and 120 MW configurations, the solution delivers industry‑leading power density—reducing the number of stacks required for a given capacity within a standardized balance of plant.

To validate performance claims, DNV audited lab and pilot test data spanning 2022–2025 and witnessed live operations at the company’s Pioneer Plant in San Jose, a one‑tenth‑scale facility running a commercial‑grade stack. The auditors confirmed HYPRPlant’s ability to sustain rated efficiency, pressure and hydrogen purity, while simultaneously gathering critical lifetime degradation data. DNV also toured Electric Hydrogen’s Devens, Massachusetts manufacturing site, citing advanced quality controls, 5S lean management practices and value‑stream mapping that meet or exceed established electrolyzer OEM benchmarks.

“DNV has the experience in reviewing new and evolving energy technologies to ensure they perform to specifications, are designed to be inherently safe and are sufficiently de-risked to be considered for bankability. This is a crucial service for bringing systems like Electric Hydrogen’s HYPRPlant to market,” said Richard S. Barnes, Executive Vice President and Director for North America, Energy Systems at DNV. “Delivering such a power-dense, flexible, turn-key electrolyzer plant is a step change for the industry for both new and experienced plant operators”.

“Building powerful electrolyzer plants at low-cost and large scale is the singular purpose of Electric Hydrogen,” explains Raffi Garabedian, CEO and Co-founder of the company. “We are honored that DNV, one of the most distinguished independent evaluation authorities, has validated and recognized our progress.”
