Exploring new liquid organic hydrogen carrier materials for a safer, more transportable energy source

To reduce CO2 emissions, the energy transition from a carbon-based energy system to a more sustainable system based on hydrogen energy is urgently needed. However, the nature of hydrogen (such as low volumetric density, flammability, and embrittlement) makes its use as a widespread energy source extremely challenging. Therefore, the key to establishing a hydrogen-based society is the safe and efficient use of hydrogen.
