First-of-its-kind green hydrogen facility begins construction in South Australia

Sparc Technologies commenced construction of a revolutionary green hydrogen pilot plant in South Australia on Tuesday, marking a significant milestone for next-generation hydrogen production technology.

The facility, located at the University of Adelaide's Roseworthy Campus, will employ photocatalytic water splitting (PWS) technology that produces hydrogen directly from water using only sunlight and a photocatalyst material – eliminating the need for expensive electrolysers.

“In an environment where major challenges exist for hydrogen projects due to the high cost of power, the requirement for new solutions to unlock low-cost green hydrogen without relying on electrolysers has never been higher,” said Sparc Managing Director Nick O'Loughlin.

The pilot plant represents a joint venture between Sparc Technologies, Fortescue Limited and the University of Adelaide. Several key milestones have already been achieved including manufacture of the linear Fresnel concentrated solar system, commencement of reactor manufacturing, and securing planning consent from local authorities.

Unlike conventional hydrogen production methods, the PWS technology decouples hydrogen production from electricity costs by using sunlight as the only energy input. This approach potentially offers significant advantages for remote locations and off-grid applications.

The facility is expected to be commissioned by mid-2025 and will allow independent testing of different reactor designs and photocatalyst materials under real-world conditions. The company secured its first patent for the reactor technology in January, with 17 additional jurisdictional reviews in progress.
