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 renewable energy.
