AI Technical Summary
During the hydrogen absorption and desorption cycle, metal hydride hydrogen storage materials undergo particle pulverization due to volume expansion and contraction, which causes internal stress to act on the inner wall of the hydrogen storage tank, potentially leading to deformation or rupture. Furthermore, the gaseous storage capacity is small, and the liquid storage carries the risk of natural evaporation.
A novel hydrogen energy storage device has been designed, comprising a cubic shell and a storage cavity with an internal storage tank. Coolant is injected through inlet and outlet pipes for cooling. A rotating tube and movable seat structure are used to control the staggered or docking of the channels. Combined with a heat-conducting plate and buffer cavity structure, the safety and stability of the storage tank are ensured.
This technology enables cryogenic storage in storage tanks, reducing the safety risks of hydrogen storage, improving storage efficiency and safety, preventing tank deformation or rupture, and enhancing transportation convenience.
