The GCW system combines decarbonization, electrolysis, solar thermal energy, and a proprietary crystallization method to transform raw water into clean, usable products – without chemicals and without generating waste brine.
Raw Water Intake
Any water source: groundwater, seawater, brackish water, surface water.
GCW Decarbonization
Patented chemical-free decarbonization process removes contaminants.
Electrolysis
Powered by renewable energy (solar PV, wind, or industrial waste heat).
GCW Crystallization
Remaining minerals and salts are recovered as valuable by-products.
Outputs
Drinking water / Ultrapure water / Green hydrogen / Recovered salts [&] minerals.
Modular. Autonomous. Earthquake-Resistant.
WHO-compliant drinking water, free of microplastics, enriched with essential minerals. Safe for direct human consumption – even in the most remote regions.
One System. Three Products.
Premium Drinking Water
WHO-compliant drinking water, free of microplastics, enriched with essential minerals. Safe for direct human consumption – even in the most remote regions.
Ultrapure Water
High-purity water for semiconductor manufacturing, medical applications, pharmaceuticals, and precision industrial processes. Meets the strictest international quality standards.
Green Hydrogen
Produced as a by-product of the electrolysis process. Green hydrogen as an energy carrier for aviation, mobility, and stationary energy storage – a cornerstone of the global energy transition, supported by UN and the Asian Development Bank.

Stand-Alone Solutions in Remote Areas
GCW systems are well suited for modular, containerized deployments in remote or off-grid locations, independently driven by hybrid power supply systems.
Low-Maintenance + No Membrane Dependency
Operational robustness through a membrane-free design. Systems are planned for long-term availability with minimal maintenance requirements.
High Raw Water Quality via Phase-Change Separation
Phase-change separation keeps non-volatile salts, heavy metals, and many inorganic contaminants in the concentrate, resulting in exceptionally high output water quality.
Suitable for Challenging Water Compositions
Designed for high salinity, fluctuating salt loads, and problematic inorganic contamination – conditions where conventional systems fail.
Low-Temperature Vacuum Operation
Lower boiling point reduces thermal stress on components and helps mitigate scaling and corrosion, extending system lifespan.
