LSBU researchers investigating metal hydride hydrogen storage for buses

Green Car Congress

On demand, the hydrogen is released from the hydride (endothermic reaction), utilizing the waste heat of the fuel cell. From Adelhelm & Jongh (2011). But concerns have been raised about the size, cost and safety of hydrogen storage in buses. Hydrogen is stored by reaction with a metal to form a hydride (exothermic reaction).
