Customer ServiceFew studies consider the optimisation of hydrogen liquefaction pressure and the reaction heat of ortho–para-hydrogen conversion, and the time/weather-dependent characteristics of solar energy are not systematically considered.

These methods offer the potential for low-cost, clean hydrogen production by mimicking the natural photosynthesis process. Solar water splitting, which uses solar energy to produce hydrogen from water, is a renewable and environmentally friendly method. Hydrogen produced via solar water splitting is efficient both economically and energetically.
Solar hydrogen generation by water splitting is more efficient than other methods, as it uses self-generated power. Similarly, solid storage of hydrogen is also attractive in many ways, including efficiency and cost-effectiveness. This can be achieved through chemical adsorption in materials such as hydrides and other forms.
The integration of the hydrogen liquefaction process with renewables (such as solar, wind, and geothermal systems) is an important direction for achieving sustainable production. At present, the SEC of the reported hydrogen liquefaction process is in the range of 5–8 kWh/kg LH2 (Aasadnia and Mehrpooya 2018b).
The exergy efficiencies of the hydrogen liquefaction process and the integrated system were 69.55% and 86.72%, respectively. Hence, with the renewables utilised, the exergy efficiency of the hydrogen liquefaction process increased by 24.69%. Exergy balance throughout the SPT–TES system
The efficiency of solar hydrogen production by water splitting is termed solar-to-hydrogen (STH), and it is estimated using Equation (1) . where Ptotal is the power density of incident sunlight (AM1.5G), jsc is short-circuit photocurrent density, 1.23 V is the voltage required for water splitting, and is the faradic efficiency.
