Abstract
High energy-density sources like hydrocarbons have negative environmental implication due to their emission of greenhouse gasses during combustion. The negative effects of greenhouse gasses are becoming more commonly observed as the global demand for energy increases. Renewable energy sourced from wind or solar farms offer a potential alternative to hydrocarbons in a theoretical capacity, but fluctuating environmental conditions limit the ready availability from renewable energy in large-scale implementations. Limited effective storage techniques for excess energy created by renewables is a key roadblock preventing the widespread use of renewables to meet global energy needs. The objective of this project was to design a methanation reaction process which utilizes green hydrogen and CO₂ sourced from industrial emissions to serve as a means of power-to-gas energy storage while reducing direct emissions. The safety and economics of this potentially revolutionary energy technique was assessed to analyze the potential viability of the project.
