The hydrogen storage density per unit volume of hydrogen storage alloy is much higher than that of high-pressure bottled methods, also higher than that of liquid hydrogen.

The hydrogen storage conditions are stable, and the hydrogen absorption and desorption process are accompanied with obvious thermal effects, it has huge application potential in the field of energy conversion and utilization.

Regardless of whether MH is used as hydrogen or a heat medium, its performance is mainly achieved in the reaction machine, and is closely related to the process of MH absorption and desorption.

The MH absorption and desorption process has a significant thermal effect and a pulverization effect caused by the periodic expansion and contraction of the crystal lattice. Therefore, the design of the reactor (reaction machine) in the MH hydrogen storage/heat storage system and its heat exchange method, hydride filling method and so on design is the kay for deciding the mass and heat transfer capacity of the reaction machine (hydrogen absorption and desorption rate, heat exchange capacity, hydrogen flow characteristics) and the key to long-term safety and stability.

Because the hydrogen release process of medium and high temperature MH alloys requires heat source to provide stable starting heat, and the process of hydrogen release requires a cold source to extract the reaction heat characteristics, we developed a series of light weight MH Hydrogen storage reaction machine, that can be used for heat recovery for medium and high temperature magnesium-based alloys.

Technical features:

1) The use of phase change materials with heating devices can quickly respond to the process of hydrogen absorption and desorption.

2) The system is independent, and the equipment is highly integrated, without external auxiliary heat flow transmission equipment.

3) Mixed with special carbon materials, which can effectively weaken uneven stress distribution and ensure heat transfer and gas flow.

4) It weakens the cyclic compression and natural sinking effects produced by the hydrogen absorption and desorption process of the static alloy reaction machine and has significant technical advantages and safety and reliability.

5) The safe filling rate can achieve 50%. The packing density of the hydrogen storage alloy in the machine is uniform and stable, and the hydrogen storage density and the cost-effectiveness of the reaction bed device are significantly improved.
