Renewable hydrogen (H<sub>2</sub>) is a promising substitute for fossil fuels, offering zero CO<sub>2</sub> emissions. However, its low volumetric energy density poses a significant challenge for efficient storage and transportation. The strategic integration of H<sub>2</sub> storage with decarbonization initiatives has emerged as a viable solution to combat global warming. This review explores the potential sources of renewable H<sub>2</sub> production, storage methods, and applications in the context of decarbonization. Among various approaches, renewable liquid production via catalytic CO<sub>2</sub> hydrogenation—specifically through the reverse water–gas shift (RWGS) reaction, Fischer–Tropsch synthesis (FTS), and methanol synthesis—stands out as one of the most promising pathways. These processes facilitate the storage and transport of renewable H<sub>2</sub> while enabling large-scale industrial applications. The conversion of CO<sub>2</sub> and renewable H<sub>2</sub> into methanol and hydrocarbons not only enhances energy storage efficiency, but also offers significant environmental benefits, contributing to the development of sustainable energy systems. Additionally, this review addresses current technological and economic challenges associated with renewable H<sub>2</sub> and its storage while proposing future research directions.

The Ni-X-AlSBA-15 (X = Y, Sm, Gd, and La) catalysts demonstrated a considerably enhanced catalytic activity and selectivity compared with that of Ni-AlSBA-15. In particular, the Ni-Gd-AlSBA-15 catalyst achieved the highest conversion of ethylene to butene (50.0 wt.%) after 12 h of time on stream. These enhancements were attributed to the improved dispersion of active sites, the presence of oxygen vacancies, and the optimized densities of the acid and Ni sites, which collectively enhanced the rate of adsorption of ethylene molecules. An increase in the selectivity of butylene (≥ 80%) confirmed that the gadolinium as a promoter had a positive effect on the catalytic activity.
