Renewable Methanol Production Using Captured Carbon Dioxide and Hydrogen Generated through Water-Splitting

Abstract

The global warming issues associated with fossil fuels have forced the world to shift towards environment-friendly alternatives. The studies on the capture and storage of CO2 have gained significant research attention, and to attract the world towards CO2 capturing and storing, it is necessary to find suitable applications for this captured CO2. Methanol is one of the products which can be produced by utilizing the captured CO2 and hydrogen that can be produced by water splitting. Keeping in view both these green fuel production processes, this study proposes a combined application of both these technologies for the production of methanol, which is an important chemical used in manufacturing industries. This review paper presents a brief study of both carbon capture and hydrogen production technologies. It also provides research trends, economic aspects, and methods of incorporating both these technologies to produce methanol. Additionally, the prospects of the approach in Oman have also been presented.
