2. Hydrogen energy technologies – an international perspectives The US administration''s bold "Hydrogen Earthshot" initiatives, "One-for-One-in-One", otherwise simply, "111" is driving and reviving the hydrogen-based research and development to realize for the generation of "clean hydrogen" at the cost of $1.00 for one kilogram in
Generally, hydrogen is produced from renewable and non-renewable energy sources. However, production from non-renewable sources presently dominates the market due to intermittency and fluctuations inherent in renewable sources. Currently, over 95 % of H 2 production is from fossil fuels (i.e., grey H 2) via steam methane reforming
Abstract. As an important raw material for chemical synthesis, hydrogen has been studied in China since the early 1960s. During this stage, hydrogen primarily served as an industrial product.

Globally, the installed capacity of wind and solar power is growing exponentially [9], as shown in Fig. 1.Wind power is one of RES that is difficult to predict accurately [10], making its integration to the grid difficult, as it causes imbalances between peak demand and production, leading the system operator to dispatch the higher cost
Energy density: Hydrogen possesses a lower energy density compared to typical fossil fuels, resulting in larger storage requirements for the same amount of energy. Researchers should prioritize the development and enhancement of hydrogen storage devices to tackle this challenge effectively (Osman et al., 2024 ).
Despite the decline in the total number of hydrogen projects since the 2021 year, the annual planned productivity will continue to increase, which indicates the onset of a new stage in the development of hydrogen energy (Fig. 3).
The current utilization rate of HRS is low, and the amount of hydrogen refuelled daily is low, resulting in hydrogen precooling consuming about 80% of the total energy consumption of HRS [6, 7, 38]. Some researchers have shown that cascade refuelling can reduce cooling energy consumption compared with single-stage refuelling.
With the maturity of hydrogen storage technology and the expansion of hydrogen utilisation scenarios, the on-site development and consumption of hydrogen energy will become more important. Ultimately, the construction of a future integrated energy system coupled with hydrogen, electricity, heat, and gas is a powerful means for
As the global energy landscape shifts towards a greener future, hydrogen''s role as an energy carrier and storage modality becomes progressively significant, making

Solid-state hydrogen storage (SSHS) has the potential to offer high storage capacity and fast kinetics, but current materials have low hydrogen storage capacity and slow kinetics. LOHCs can store hydrogen in liquid form and release it on demand; however, they require additional energy for hydrogenation and dehydrogenation.
On one hand, liquid hydrogen storage requires a low temperature (20 K) and has a higher energy consumption than other hydrogen storage methods [110], [116]. During the hydrogen liquefaction process, approximately 40% of energy is lost [117] .

Hydrogen has a very low density both as a gas and a liquid. Its density is 0.08988 g/l in gaseous state, i.e. 7% of the density of air; 70.8 g/l as liquid (at -253°C), i.e. 7% of the density of water; and 70.6 g/l as solid (-262°C). For comparison, the density of typical fuels is shown in Table 1.
The hydrogen storage density is high, and it is convenient for storage, transportation, and maintenance with high safety, and can be used repeatedly. The hydrogen storage density is low, and compressing it requires a lot of energy, which poses a high safety risk due to high pressure.
In 2022, installed capacity in China grew to more than 200 MW, representing 30% of global capacity, including the world''s largest electrolysis project (150 MW). By the end of 2023, China''s installed electrolyser capacity is expected to reach 1.2 GW – 50% of global capacity – with another new world record-size electrolysis project (260
