To the public, formic acid (CH₂O₂) is best known as nettle, a knowledge resulting from unpleasant interactions of the plant with humans. Less known is the potential of formic acid to act as an energy storage medium, that could compete with hydrogen or metal powder fuels, to name a few. The interesting energy storage aspect of the liquid is that it contains 53 gram/dm3 hydrogen at room temperature and atmospheric pressure, which is 3.5 times as much as compressed hydrogen gas at 350 bar.
In order to investigate the potential of formic acid, six parties involved in the “Power-2-FA Consortium” want to build a test-installation to produce formic acid, based on a n undisclosed but patented process.
