Among all introduced green alternatives, hydrogen, due to its abundance and diverse production sources is becoming an increasingly viable clean and green option for transportation and energy storage.
The idea behind the LOHC is that the hydrogen is stored in a molecule that contains double bonds via a catalytic reaction. The hydrogen accumulated in this way can be released at any time and at any location via a catalytic dehydrogenation reaction. In this context, chemical hydrogen storage and transport systems are of great interest.
6.5 Alcohol Metabolism. The other energy source is alcohol. The alcohol we consume contains two carbons and is known as ethanol. Figure 6.51 Structure of ethanol1. Ethanol is passively absorbed by simple diffusion into the enterocyte. Ethanol metabolism occurs primarily in the liver, but 10-30% is estimated to occur in the stomach2. For the ...
