Abstract (EN): Achieving net-zero emissions in the atmosphere is one of the most critical challenges faced by society. Thus, the research efforts should be intended to develop and implement new green sources to substitute the traditional fossil fuels avoiding carbon dioxide emissions. Among others, hydrogen energy is positioned as promising renewable energy but still requires overcoming the disadvantages of storage. In this context, ensuring a safe process employing reasonable volumes and pressures is one of the hotspots which are needed to address. Sodium borohydrides with significant advantages such as low vapor pressure, stability, or high hydrogen storage capacity have been largely studied in the last years. Catalysts and the different operating conditions are well known in this field. This work intends to demonstrate the benefits of the employment of additives to improve process control in terms of yield. Specifically, sodium carboxymethyl cellulose additive in 1 wt %, provides performance of 85 %, concluding that although further efforts are required, this approach could improve the hydrolysis of borohydrides for hydrogen storage. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
