The following is a case highlight from a paper that can be read here.
As the need for cleaner forms of energy grows, metal hydrides look to be a promising way to store enough hydrogen to meet future energy requirements. A complex metal hydride storage medium of 2LiBH4-MgH2 was proposed as an optimal candidate for hydrogen storage based on its cost, availability, and energy density. However, the thermodynamic and heat transfer properties of the system need to be understood in order to design proper storage tanks for the material.
The effective thermal conductivity of the complex metal hydride was measured at different temperatures in both the absorbed and desorbed states using C-Therm’s Modified Transient Plane Source (MTPS) sensor.
This graph shows that while the absorbed state has a higher thermal conductivity, both exhibited quite low thermal conductivities compared to other common materials. This provided insight for the design of a thermal management system; since the hydride itself would be insufficient at dissipating enough heat, other solutions must be found such as additives or active cooling.
