Soda stream: Sodium bicarbonate was cyclically hydrogenated in aqueous solution to sodium formate at 100 bar H2 in the presence of a RuII–sulfonated phosphine catalyst. The system functions as a true charge/discharge device for storage and delivery of hydrogen without the need for isolation of either formate or bicarbonate.
Papp et al. (Wed,) studied this question.
