Methanol

as a carrier of hydrogen energy

holds promise in advancing the exploitation of hydrogen energy and achieving carbon neutrality goals. This paper reviews the properties

synthesis methods

and application scenarios of methanol

with a particular focus on summarizing and comparing methanol utilization technologies under the background of the dual carbon

and analyzes the current state of existing methanol application technologies. In terms of direct utilization

direct combustion of methanol is relatively easy to achieve and can be employed for energy supply in internal combustion engines

boilers

and direct methanol fuel cells. However

the low calorific value and strong acidic property of methanol restrict the application of these technologies to some extent. In terms of facilitating hydrogen energy utilization

methanol can serve as a hydrogen energy carrier to enhance hydrogen storage and transportation and provide high-purity and high-quality hydrogen

thereby effectively advancing the development and utilization of hydrogen energy

which should be given attention and development. In terms of industrial raw materials

methanol utilization technologies are relatively mature

and the use of green methanol can also achieve carbon fixation from carbon dioxide. Overall

methanol production and utilization technologies are relatively mature. Nevertheless

further technological development is needed in areas such as methanol fuel cells and direct combustion. It is recommended to develop from multiple aspects such as technological innovation

planning layout

policy support

and relevant standard system construction to ensure the gradual improvement of methanol technology.
