The hydrogen is often stored by high-pressure tank, adsorbents and hydrogen storage materials.
Among them, chemical hydrogen storage method is preferred to because the purity of generated hydrogen, the rapidity in hydrogen production and the portability of hydrogen storage materials is better than the other methods.

Biodiesels are typically made from renewable organic raw materials such as jatropha, soybean or rapeseed oils, animal fats, waste vegetable oils or microalgae oils [2].
Apart from that, this process combines the benefits of equilibrium reaction with distillation in order to achieve a substantial progress in promoting reaction conversion as a result of constant recycling of unconverted materials and removal of products.
