Hydrogen based energy is a promising alternative to carbon-based fuel, and is more environmentally sustainable. However, due to safety concerns, it is important to understand hydrogen’s thermal properties, such as thermal conductivity.
Across the world, there is a concerted effort to move towards a hydrogen-based energy economy as a way to combat the environmental concerns from current carbon energy sources. Thus, there is a need for practical, inexpensive hydrogen storage materials.
Thermal conductivity of hydrogen storage materials plays a crucial role in the design of a safe storage configuration. Hydrogen gas can pose a safety hazard due to the exothermic reactions it undergoes. Therefore, effective thermal management is a necessity to ensure the safety of the apparatus. The thermal conductivity of hydrogen storage materials can be measured using the Modified Transient Plane Source (MTPS) sensor, either in a glove box with an inert atmosphere, or by using a C-Therm High Pressure Cell (HPC). The HPC allows for the sample to be isolated from air and therefore safe from combustion.
C-Therm’s high pressure cell test accessory can safely characterize the thermal conductivity of samples under elevated pressure environments up to 2000 PSI.
Thermal conductivity also plays a role in determining the rate hydrogen generation for some storage configurations. Since metal hydrides release hydrogen upon heating, it is important to understand the thermal characteristics of the hydrides and their housings to accurately characterize how much heat the hydride is absorbing.
This webinar will explore the need for hydrogen storage materials particularly in electric vehicles, the importance of thermal properties for safety and performance, and how the MTPS and HPC can be used to safely characterize these energetic materials.
