Water-conscious green hydrogen production and conversion for harnessing long-term storage in remote renewable microgrids Energy Convers. Manag. (IF 9.9) Pub Date : 2024-08-09 Hedayat Saboori, Hesam Pishbahar
Water plays a pivotal role in the production of green hydrogen, requiring meticulous management. Approximately 10 L of water are needed to produce one kilogram of hydrogen through electrolysis. Furthermore, roughly 10–20 L per kilogram are required for process cooling. A share of this water consumption is blowdown, which can be recirculated, while water is also generated as a byproduct of energy conversion

A deep-learning-boosted surrogate model of a metal foam based protonic ceramic electrolysis cell stack for uncertainty quantification Energy Convers. Manag. (IF 9.9) Pub Date : 2024-08-07 Zheng Li, Chen Wang, Xi Chen, Na Yu, Lei Xing, Jin Xuan, Minfang Han, Meng Ni
Protonic ceramic electrolysis cells (PCECs) are widely considered as an emerging technology that shows capability for enabling environmentally friendly large-scale production of hydrogen. PCEC stacks’ performance is considerably lower compared to smaller, lab-scale button cells. This performance gap is largely attributed to the highly uneven distribution of reactants throughout the larger cell or stack
