The company Hysata Pty Ltd is developing a unique concept in electrochemical cells for green hydrogen production, wherein water is supplied to the hydrogen- and oxygen-evolving electrodes by capillary-induced transport within a porous inter-electrode separator. This approach, which was pioneered at the University of Wollongong,1 leads to inherently bubble-free production of the hydrogen and oxygen gas at the electrodes.
Alkaline ‘Capillary-Fed’ Electrolysers (CFE) of this type display remarkably high energy efficiencies of only 40.4 kWh consumed per kilogram of hydrogen produced in the cells and 41.5 kWh consumed per kilogram hydrogen produced at the full system level. This substantially improves upon the best state-of-the-art commercial electrolysers, which require 47.5 kWh/kg at the cells and 50-53 kWh/kg at the full system level. It also supersedes the targets of 42 kWh/kg at the cells and 44 kWh/kg at the system level for green hydrogen production set by the International Renewable Energy Agency (IRENA) for the year 2050. Given that the largest cost of producing green hydrogen is the cost of the electricity required, the new approach to energy efficiency being commercialised by Hysata enables notably lower costs and is encapsulated in the company’s moto: ‘Green Hydrogen. Efficiency Wins’.
This presentation will review the Capillary-Fed Electrolysis (CFE) technology being commercialised by Hysata, as well as its scale-up to full commercial size and implementation in the first commercial demonstration projects.
