From Science Daily: New catalyst turns carbon dioxide into clean fuel.
New catalyst turns carbon dioxide into clean fuel source
The gist of it is that manganese, as a catalyst, can be used to make formate, the precursor to formic acid. Formate has the chemical formula of HCO2. Formic acid is HCO2H. The idea is to use manganese to make formate, which in turn can chemically store hydrogen.
First thought: the ants are really going to love this one: they are attracted to formic acid. Second: thought: What is the cost in efficiency in making formic acid, then using it to produce hydrogen. Third thought: this may be safer than dealing with H2, but what kind of bulk are we looking at? One mole of formate can hold one mole of hydrogen, but what is that bulk-wise? As a liquid, formic acid should be right at incompressible. Formic acid has a density of 1.22 g/ ml. Molar weight is 46.0254 g / mole, which should be 37.7257 ml to hold 1 mole of hydrogen. I don’t know how usable that is.
It’s interesting because that might be a safer and cheaper form of energy storage that lithium batteries. If it’s practical, it could address the energy storage problems that inhibit solar and wind electricity generation.
