Bubble-Free Capillary Water Electrolysis
A new approach to industrial water electrolysis and Reflections on Commercialisation of Technological Innovations
Topic: Bubble-Free Capillary Electrolysis – A new approach to industrial water electrolysis and Reflections on Commercialisation of Technological Innovations
This hybrid event will be diffused online and in-person with laboratory tours at the in-person session.
Recordings of past Hydrogen Links Sessions can be found in the video section of the HSA Knowledge Portal.
About the topic:
Renewable, or green, hydrogen will play a critical role in the future decarbonization of our economy, particularly of the so-called ‘hard-to-abate’ sectors like heavy transport, steel, chemicals, and aviation. However, renewable hydrogen is presently not cost-competitive with fossil fuels due to the poor energy efficiency of state-of-the-art commercial water electrolysers. This presentation will describe a remarkable new technology that promises to deliver cost-competitive renewable hydrogen in the near future. The technology employs an electrochemical cell architecture in which water is fed by capillary action to the electrodes, allowing for direct production of hydrogen without the formation of gas bubbles. ‘Bubble-free’ water electrolysers of this type demonstrate efficiencies of ≥95%, equating to an energy consumption of 41.5 kWh per kg hydrogen (vs. 50-53 kWh/kg by present-day commercial electrolysers). This exceeds the target of the International Renewable Energy Agency for the year 2050. The commercialisation of such technological innovations will also be reflected upon. The demand for cost-competitive green hydrogen is such that the company developing this new technology, Hysata Pty Ltd, already has an order book of more than $5 billion.
