Formic acid energy storage

Can formic acid be used for energy storage?

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.

Is formic acid a hydrogen energy carrier?

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 safer to store and transport.

Can formic acid be used as a hydrogen storage material?

The latter process, i.e., CO 2 hydrogenation, has long been studied and many efficient procedures have been already developed. [9,10] Accordingly, most research into developing formic acid as a hydrogen storage material is focused on finding the catalyst materials for formic acid decomposition.

Is formic acid a good fuel?

Owing to the better efficiency of DFAFCs compared to several other PEMFCs and reversible hydrogen storage systems, formic acid could serve as one of the better fuels for portable devices, vehicles and other energy-related applications in the future.

Can CO2 and H2 store energy in formic acid?

The authors report a novel catalyst that uses CO2 and H2 to store energy in formic acid. Using a homogeneous Ir catalyst with a proton-responsive ligand, they show the first reversible and recyclable hydrogen storage system that operates under mild conditions using CO2, formate and formic acid.

Can formic acid be used as a fuel without Reformation?

In recent years, formic acid has been used as an important fuel either without reformation (in direct formic acid fuel cells, DFAFCs) or with reformation (as a potential chemical hydrogen storage material).
