Optimal carbon dioxide methanation using green hydrogen

Abstract

The surge in demand for energy has resulted in a significant transformation of the worldwide energy sector, causing a shift toward the advancement of energy sources that are both efficient and sustainable. In order to address environmental issues and advance a sustainable energy future, renewable energy (RE) sources and carbon dioxide (CO2) utilisation are crucial. Greenhouse gas (GHG) emissions increments are driven by economic and population growth, which are increasing. The rise in growth has led to an increase in the atmospheric concentration of CO2. Due to this situation, carbon capture, utilisation, and storage (CCUS) seems to be a promising approach to reducing CO2 emissions. Among all the carbon utilisation strategies available, CO2 methanation is promising for producing fuel for future energy. This project aims to develop an optimisation model for a mobile pilot facility for CO2 methanation using green hydrogen (H2) generated from solar photovoltaic (PV). In this project, an energy model for the design of a solar energy source for hydrogen production integrated with battery energy storage to ensure optimum usability of the renewable energy source for CO2 utilisation will be developed.
