(1) Methanol blended with gasoline and diesel. The two oil crises that occurred in the 1970s, along with strict environmental regulations, **spurred the development of fuels for motor vehicles. Methanol gasoline is a liquid clean fuel, and it has long been used as a fuel for clean vehicles internationally.** In terms of calorific value, methanol contains more oxygen, allowing for complete combustion when mixed with gasoline; as a result, it provides strong power. Internationally and domestically, there are currently challenges such as increasing energy shortages, a growing number of cars, and rising oil prices. Its superior fuel quality has further drawn people’s attention. Through years of research and development, China has established a certain foundation in the development and application of methanol fuel. Extensive practical work has been carried out on experimental studies involving the addition of 5%, 15%, 25%, and 85% methanol to gasoline, as well as the use of pure methanol (100%) as a vehicle fuel. In particular, when methanol is used in low proportions, no modifications to the vehicles are required; it can be directly mixed into gasoline for use. (2) Methanol fuel cell. To meet the global needs for sustainable energy use and environmental protection, fuel cell technology has become a focal point in international high-tech research and development. A power generation technology that uses methanol directly as a fuel, and converts chemical energy into electrical energy spontaneously through the electrochemical reaction between methanol and oxygen, is called a direct methanol fuel cell (DMFC). DMFC is a fuel cell with excellent comprehensive performance, simple operation, and broad application prospects. Its main feature is that methanol can be used directly in the anodic reaction to generate electricity without any pre-treatment, with water and carbon dioxide being produced as by-products; it causes no environmental pollution and thus represents a clean source of power. It has a high energy conversion rate, with an actual efficiency of over 70%, which means that the utilization efficiency of fuel can be increased by more than twice – making it an energy-efficient power generation technology. Thanks to its characteristics such as high energy density, high power, and zero pollution, fuel cells have become the most promising mainstream alternative energy supply technology in recent years. Furthermore, as consumers demand more functions from portable electronic devices, and given that traditional secondary batteries provide significantly insufficient operating time, direct methanol fuel cells have become the most promising mainstream power source for future electronic devices in recent years. (3) Produce dimethyl ether fuel. In addition to its wide range of applications in the fields of daily chemicals, pharmaceuticals, pesticides, dyes, and coatings, dimethyl ether (DME) also possesses fuel-related advantages such as convenience, cleanliness, a high cetane number, good performance as a fuel, low pollution levels, the ability to become a liquid under slight pressure, and ease of storage. It effectively resolves the global challenge of the conflict between energy and pollution, and is hailed as the \"green fuel of the 21st century\". In our country, the conditions for the widespread use of dimethyl ether as a fuel are already well-established. By switching boilers to use dimethyl ether as fuel or by installing gas turbines that run on dimethyl ether, it is also possible to replace diesel and fuel oil, whose supply is becoming increasingly strained in thermal power generation, with dimethyl ether. Currently, the production technologies and scale of methanol and DME make DME an economically viable fuel, offering broad prospects for its development.
