Introduction
IntroductionPower-to-gas (PTG) is the process that converts electrical energy into chemical energy by means of electrochemical or chemical reactions. Normally, the chemical species that are obtained are in gaseous form, most often hydrogen or methane. Gases can be relatively easily stored in tanks for later use.Conversely, the term gas-to-power entails the conversion of the energy stored in chemical form to electrical energy by means of combustion of the gas in FCs, where chemical energy is directly converted to electrical energy, or thermal cycles in turbines, where chemical energy is converted first in mechanical energy and then in electrical energy.This way of storing electric…
