Irish Hydrogen Alliance is pioneering a fully integrated modular device for seawater desalination, green hydrogen production, clean power generation, and hydrogen refueling — engineered as one unified system.
Core Technology
Our modular platform combines six purpose-built subsystems into a single, scalable device — deployable offshore, coastal, or on-grid. Each module operates independently or as part of the full integrated chain.
Advanced reverse osmosis combined with electrodialysis to convert raw seawater into high-purity feedwater.
Module 01Multi-stage purification pipeline delivering ultra-pure water for precision electrolysis feedstock.
Module 02PEM and alkaline electrolysers powered entirely by renewables split purified water into hydrogen.
Module 03Stored hydrogen is converted back to electricity via fuel cell stacks for baseload or peak-shaving.
Module 04Solid oxide and PEM fuel cells engineered for high power density and longevity.
Module 05Fully integrated HRS infrastructure directly coupled to the production module (700-bar).
Module 06End-to-End Pipeline
The modular chain transforms seawater into hydrogen, fresh water, oxygen, and electricity within a single continuous process.
Raw ocean water captured via offshore/coastal intake
RO membranes remove salts and minerals
Multi-stage filtration to electrolyser-grade
Renewable-powered H₂ + O₂ splitting
Hydrogen stored or fed to fuel cell generation
HRS refuelling and grid power export
Our Alliance
We unite engineers, investors, and policy leaders under one strategic alliance to make clean hydrogen technology commercially viable, globally scalable, and economically accessible.
Each module can be deployed independently or as a full integrated system.
Addressing the global freshwater crisis and the transition away from fossil fuels simultaneously.
Headquartered in Malahide, Dublin, we leverage Ireland's Atlantic wind resources as Europe's gateway.
Platform Capability Index
Economic Advantages
Energy from wind and solar installations powers green hydrogen production, with excess electricity sold to the national grid or EV charging stations.
Desalinated seawater serves two purposes: providing high-purity feedstock for electrolysis and supplying fresh water to coastal regions.
Deep integration of generation, desalination, and electrolysis minimizes losses and optimizes the capacity factor compared to standalone units.
Shared infrastructure and multi-resource monetization significantly lower CAPEX and OPEX, ensuring market competitiveness.
