Interesting development reported by FuelCellWorks.com. Of course, the most controversial claim coming out of this development will likely be that:
The production of so-called “green hydrogen” from alcohol also produces carbon emissions but at a much lower rate.
“In addition, it is carbon that was already in the biosphere, because it comes from the vegetables used to manufacture alcohol. Therefore, it does not add carbon dioxide to the atmosphere,” the scientist said.
I suppose one might ask if putting any carbon back into the atmosphere is a good thing considering the overabundance of this element already present. Still, this looks like a promising development.
