Abstract

Building on previous successful collaborations among CNR-ITAE, USP-IQSC, this project proposes an innovative initiative to develop efficient hydrogen (H2) production through water electrolysis. It will use advanced solid oxide electrochemical cells (SOECs) and solid-state systems powered by renewable and waste-derived fuels like sugarcane ethanol by-products, urea, and glycerol. The aim is to produce green hydrogen with minimal electrical input, advancing the technology of both SOECs and solid oxide fuel cells (SOFCs). Given the urgency of climate and energy challenges, the project focuses on converting surplus renewable energy into storable fuels. SOECs are highlighted for their efficiency and scalability, but currently rely on Critical Raw Materials (CRMs). The project seeks to replace these with CRM-free, entropy-stabilized materials that offer better conductivity and stability. A key deliverable is a prototype SOEC operating with innovative, sustainable materials and low electrical energy input. This will support the green hydrogen market and promote public acceptance of clean energy. With strong scientific backing and partnerships with companies like SolydEra, ITAIPU, ENEL, SHELL, and EDISON, the project is expected to deliver high innovation and commercial value, supported by investments from CNR and FAPESP.
