The main objectives of SAHARA include the development of a novel photoelectrode with high material utilization, extended lifetime, and low content of CRM. Innovative coating processes are to be employed for this purpose. In addition, groundbreaking cell designs are to be developed and system integration implemented to enhance efficiency. Another focus of the project is ensuring sustainability and high recyclability through thoughtful design. This is made possible through transnational collaboration, which brings together expertise in catalyst and electrode manufacturing, photoreactor design and testing, recycling, as well as economic and environmental assessment.

The SAHARA project aligns with the goal of the European Green Deal to achieve a climate-neutral economy by 2050. With a focus on TRI 3, it addresses the growing demand for renewable hydrogen production, which is crucial for achieving climate neutrality. SAHARA aims to advance photochemical solar H₂ production and contribute to the objectives of CM2023-05 through innovative materials, groundbreaking designs, and sustainability measures. The target technology readiness level (TRL) 6 is being pursued.
