Formic acid has been proposed as a hydrogen energy carrier because of its many desirable properties, such as low toxicity and flammability, and a high volumetric hydrogen storage capacity of 53 g H 2 L −1 under ambient conditions. Compared to liquid hydrogen, formic acid is thus more convenient and...
