Power-to-X concepts promise a reduction of greenhouse gas emissions simultaneously guaranteeing a safe energy supply even at high share of renewable power generation, thus becoming a cornerstone of a sustainable energy system. Power-to-syngas, that is, the electrochemical conversion of steam and carbon dioxide with the use of renewably generated electricity to syngas for the production of synfuels and high-value chemicals, offers an efficient technology to couple different energy-intense sectors, such as "traffic and transportation" and "chemical industry". Syngas produced by co-electrolysis can thus be regarded as a key-enabling step for a transition of the energy system, which offers additionally features of CO -valorization and closed carbon cycles. Here, we discuss advantages and current limitations of low- and high-temperature co-electrolysis. Advances in both fundamental understanding of the basic reaction schemes and stable high-performance materials are essential to further promote co-electrolysis.

“…In addition, at higher current densities, although a clear increase in the CO concentration is observed, the H 2 concentration remains nearly unchanged [26]. The most likely reason is that the H 2 produced by the electrolysis of steam is mainly consumed by the RWGS reaction to produce CO [8,27]. The impact of these trends warrants further study and specifically these results require more analysis and interpretation.…”

“…In contrast, obtaining a large amount of H 2 by the hydrolysis reaction of active metallic is relatively easy, which is an optional method before the widespread promotion of the ideal hydrogen production strategies (electrocatalysis and photocatalysis hydrogen generation). [37][38][39][40][41][42] The theoretical hydrogen generation capacity of Al is 1.245 L, which is higher than that of Mg (1.0 L). Therefore, considering the raw materials, hydrogen production medium, equipment, conditions, efficiency, and the overall hydrogen storage link, hydrogen production by alloy hydrolysis will be more economical, simple, and easy, currently.…”

Summary In this study, the metallurgical melting Mg‐10wt.%Ni (Mg10Ni) alloy is firstly modified by high‐energy ball milling (HEBM) and then surface catalysts expanded graphite (EG) or MoS2 or EG‐MoS2 are introduced to prepare Mg10Ni‐M (M = EG, MoS2, and EG‐MoS2) composites. The effects of surface catalysts on hydrolysis hydrogen generation of HEBM Mg10Ni alloy are comprehensively investigated. Their kinetics, rate‐limiting steps, and apparent activation energies are investigated by fitting the hydrolysis curves at different temperatures. The results indicate that the total hydrogen generation capacities of prepared Mg10Ni‐M (M = EG, MoS2, and EG‐MoS2) composites are 200, 170, 674, and 720 mL·g−1 within 1 minute at 291 K. The capacity and yield of Mg10Ni are 500 mL·g−1 and 56% within 15 minutes. The surface catalysts EG or MoS2 or EG‐MoS2 can distinctly elevate the initial H2 produce rate and promote the complete hydrolysis process. The highest capacity and generation yield within 15 minutes are 740.8 mL·g−1 and 91% obtained by HEBM Mg10Ni‐EG‐MoS2 composite at 291 K. The surface catalysis can promote high generation yield of Mg10Ni alloy in a short time.
