Project summary description:
Sparc Hydrogen is developing next generation green hydrogen technology using a process known as photocatalytic water splitting (PWS). This process is an alternative to producing green hydrogen via electrolysis, using only sunlight, water and a photocatalyst. Sparc Hydrogen’s patent pending solar reactor is demonstrated to improve the efficiency of PWS to separate hydrogen from water. Given lower infrastructure requirements, and energy use, if successful, the ‘Sparc Green Hydrogen’ process has the potential to deliver a cost competitive advantage over electrolysis driven by costly renewable energy. With the technology proven in a prototype testing at CSIRO’s Energy Centre in 2024, Sparc Hydrogen is embarking on a pilot testing phase to advance the technology to TRL 6-7. Design and engineering work is currently taking place for the pilot facility, expected to be located at the University of Adelaide’s Roseworthy campus.
