In this reaction, natural gas is reacted with steam at an elevated temperature to produce carbon ... WebElectrolysis is a leading hydrogen production pathway to achieve the Hydrogen Energy Earthshot goal of reducing the cost of clean hydrogen by 80% to $1 per 1 kilogram in 1 decade ("1 1 1"). Hydrogen produced via electrolysis can result in zero greenhouse gas emissions, depending on the source of the electricity used.
