How can possible electrical energy to converted in to chemical energy
Hi Anshul,
Batteries do just that. Store electricity as chemical energy and release the power later. Currently, the only way known is to split water into hydrogen (and oxygen) using electrolysis and try to bind the hydrogen to carbon. There are some interesting developments like for instance making alcohol with help of enzymes and electricity from carbon dioxide and water.
If on the other hand, By chemical energy, a traditional fuel is meant that burns to release energy, it is possible but the process is not a single step method, rather a combination of steps.
The entire process is called power to gas or power to liquid. As a first step, electrolysis is performed on the water to split it into its constituent hydrogen and oxygen. Then in the second step, the oxygen is removed. Then in the third step, the methanation of hydrogen with carbon dioxide is done using a reaction known as the Sabatier reaction. The resulting fuel is called SNG or Substitute Natural Gas.
Good Luck!
