“…Gaseous hydrogen storage is a method of storing hydrogen using high-pressure containers. According to the pressure level, storage containers can be divided into Type I (<20 MPa), Type II (20-30 MPa), Type III (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45), and Type IV (>45 MPa) [21,22]. Type I cylinders are usually made of seamless steel cylinders, and Type II cylinders are wound with glass-fiber-reinforced materials on the outside of the steel cylinders.…”

“…These organic compounds often possess high porosity or polarity, facilitating the efficient adsorption and release of hydrogen. Under the influence of pressure and temperature, hydrogen is adsorbed or absorbed into the organic material, forming hydrogen compounds and enabling its storage [34][35][36]. This method offers several advantages.…”

Solid-state hydrogen storage technology has emerged as a disruptive solution to the “last mile” challenge in large-scale hydrogen energy applications, garnering significant global research attention. This paper systematically reviews the Chinese research progress in solid-state hydrogen storage material systems, thermodynamic mechanisms, and system integration. It also quantitatively assesses the market potential of solid-state hydrogen storage across four major application scenarios: on-board hydrogen storage, hydrogen refueling stations, backup power supplies, and power grid peak shaving. Furthermore, it analyzes the bottlenecks and challenges in industrialization related to key materials, testing standards, and innovation platforms. While acknowledging that the cost and performance of solid-state hydrogen storage are not yet fully competitive, the paper highlights its unique advantages of high safety, energy density, and potentially lower costs, showing promise in new energy vehicles and distributed energy fields. Breakthroughs in new hydrogen storage materials like magnesium-based and vanadium-based materials, coupled with improved standards, specifications, and innovation mechanisms, are expected to propel solid-state hydrogen storage into a mainstream technology within 10–15 years, with a market scale exceeding USD 14.3 billion. To accelerate the leapfrog development of China’s solid-state hydrogen storage industry, increased investment in basic research, focused efforts on key core technologies, and streamlining the industry chain from materials to systems are recommended. This includes addressing challenges in passenger vehicles, commercial vehicles, and hydrogen refueling stations, and building a collaborative innovation ecosystem involving government, industry, academia, research, finance, and intermediary entities to support the achievement of carbon peak and neutrality goals and foster a clean, low-carbon, safe, and efficient modern energy system.

“…There are still only limited studies on the electrocatalytic hydrogenation of LOHC + . 42 One of the few studies that refers specifically to LOHC is a recent paper by Shiraz et al 43 They studied the proton-coupled electron transfer (PCET) reaction of 9-fluorenone/fluorenol as a model for the hydrogenation of LOHC. However, the latter involves the hydrogenation of the aromatic ring rather than the CQO to CH-OH reaction.…”

“…There is already work on electrochemical dehydrogenation of LOHCs [ 76 – 77 ]. In one example, DDQ was used to remove hydrogen from secondary amines by oxidizing them, followed by reoxidation of the hydrogenated DDQ at the electrode to establish a redox catalysis cycle [ 76 ].…”

This review surveys advances in the literature that impact organic sacrificial electron donor recycling in artificial photosynthesis. Systems for photocatalytic carbon dioxide reduction are optimized using sacrificial electron donors. One strategy for coupling carbon dioxide reduction and water oxidation to achieve artificial photosynthesis is to use a redox mediator, or recyclable electron donor. This review highlights photo- and electrochemical methods for recycling amines and NADH analogues that can be used as electron donors in artificial photosynthesis. Important properties of sacrificial donors and recycling strategies are also discussed. Compounds from other fields, such as redox flow batteries and decoupled water splitting research, are introduced as alternative recyclable sacrificial electron donors and their oxidation potentials are compared to the redox potentials of some model photosensitizers. The aim of this review is to act as a reference for researchers developing photocatalytic systems with sacrificial electron donors, and for researchers interested in designing new redox mediator and recyclable electron donor species.
