WebNov 4, 2024 · Formic acid (53 g H 2 /L) is a promising liquid storage and delivery option for hydrogen for fuel cell power applications. In this work we compare and evaluate several process options using formic acid for energy storage. Each process requires different steps, which contribute to the overall energy demand. WebFormic acid is a by-product, of the production of levulinic acid from hydroxymethylfurfural. This C-1 compound is formed in equimolar ratio in comparison to levulinic acid. Currently the use of formic acid in fuel cells is under investigation [51]. In the presence of platinum, formic acid decomposes with a release of hydrogen and carbon dioxide.
