EPS-H2GEN

EPS-H2GEN – Support Offshore Seawater-to-Hydrogen Dedicated Electrolyzer

EPS-H2GEN is a high-power, marine-optimized PEM (Proton Exchange Membrane) electrolysis system engineered for deepwater floating offshore wind platforms. Designed to operate reliably in harsh ocean environments, it integrates seawater desalination with ultra-pure water electrolysis to produce green hydrogen on-site—eliminating the need for costly subsea transmission infrastructure.

Key features include:

Modular capacity: 500–3000 Nm³/h, scalable to 50 MW clusters
Ultra-low energy consumption: ≤4.3 kWh/Nm³
Rapid dynamic response: ≤5 seconds, ideal for direct coupling with variable wind power
Marine-hardened design: corrosion-resistant materials, anti-sloshing stack structure, and lightweight skid mounting
Smart unmanned operation: AI-driven remote monitoring and predictive maintenance via satellite

Compliant with CCS Guidelines for Offshore Hydrogen Production Facilities (2025) and international safety standards, IEPONE-H2GEN enables cost-effective, zero-carbon hydrogen production at sea—turning offshore wind into transportable green fuel for industry, shipping, and beyond.

Description

IEPONE-H2GEN

Offshore Seawater-to-Hydrogen Dedicated Electrolyzer Solution

1. Product Positioning

IEPONE-H2GEN is a high-power PEM (Proton Exchange Membrane) water electrolysis hydrogen production system specifically designed for deepwater floating offshore wind platforms. It adopts a "seawater desalination + pure water electrolysis" technical pathway, ensuring long-term stable operation under harsh marine conditions. This solution strictly complies with the China Classification Society (CCS) Guidelines for Offshore Hydrogen Production Facilities (2025), supporting off-grid operation, remote intelligent control, and unmanned maintenance—enabling on-site conversion of offshore wind power into high-purity green hydrogen.

Note: The system does not directly electrolyze seawater. A pre-installed high-efficiency reverse osmosis (RO) unit ensures feedwater conductivity < 0.1 μS/cm to protect PEM stack longevity.
