Abstract

See full text

Method of storing hydrogen by forming a first ionic liquid by inducing a borohydride in a second ionic liquid comprising a cation and an anion comprising borate, and forming the second ionic liquid by releasing the hydrogen out of the first ionic liquid by using water and/or a catalyst, which method is characterized in that the first and the second ionic liquid are both water miscible and the second ionic liquid is separated, particularly is salted out, from solution in water by adding a separation inducer; certain ionic liquids for storing and releasing hydrogen comprising a borohydride or for preparing a ionic liquid for storing and releasing hydrogen comprising a borate; and a process for preparing ionic liquids for storing and releasing hydrogen comprising a borohydride.
