Hydrogen storage and transportation have always been bottleneck links restricting the development of the hydrogen energy industry. Traditional high-pressure gaseous hydrogen storage requires expensive carbon fiber tanks and high-pressure compression equipment, while liquid hydrogen storage faces extremely high energy consumption and evaporation losses. Magnesium-based solid-state hydrogen storage technology utilizes the reversible chemical reaction between magnesium and hydrogen to achieve high-density safe storage of hydrogen, featuring inherent safety, high hydrogen storage density, and integrated purification.
According to the project leader, the demonstration device operates stably with good hydrogen absorption/desorption cycling performance, and has currently accumulated over 1000 hours of operation. Calculations show that adopting magnesium-based solid-state hydrogen storage technology can reduce comprehensive hydrogen storage and transportation costs by approximately 30%. Next, the research team will continue optimizing the hydrogen storage performance and cycle life of magnesium alloy materials, promoting large-scale application of this technology in scenarios such as hydrogen refueling stations, distributed energy, and hydrogen power generation.
