Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
The methanol economy is a suggested future economy in which methanol and dimethyl ether replace fossil fuels as a means of energy storage, ground transportation fuel, and raw material for synthetic hydrocarbons and their products.
Direct-methanol fuel cells are unique in their low temperature, atmospheric pressure operation, which lets them be greatly miniaturized. [46] [47] This, combined with the relatively easy and safe storage and handling of methanol, may open the possibility of fuel cell-powered consumer electronics, such as laptop computers and mobile phones.

RMFC systems offer advantages over direct methanol fuel cell (DMFC) systems including higher efficiency, smaller cell stacks, less requirement on methanol purity, no water management, better operation at low temperatures, and storage at sub-zero temperatures because methanol is a liquid from −97.0 to 64.7 °C (−142.6 to 148.5 °F) and as ...
In contrast to indirect methanol fuel cells, where methanol is reacted to hydrogen by steam reforming, DMFCs use a methanol solution (usually around 1M, i.e. about 3% in mass) to carry the reactant into the cell; common operating temperatures are in the range 50 to 120 °C (122 to 248 °F), where high temperatures are usually pressurized.
As the steam reforming of methanol is more simple and efficient (catalyst bed temperature below 280°C) compared to reforming of other fuels and because of the low cost and high purity of conventional methanol and renewable methanol (e.g. made from waste or renewable power) as well as because of the simple storage of methanol, most HT-PEM fuel ...
JOHANNESBURG (AP) — The toxic chemical, methanol, has been identified as a possible cause of the deaths of 21 teenagers at a The post Methanol, used as fuel, found in bodies of 21 underage South ...
This eliminates the need for storage of two products, including pressure storage for liquefied petroleum gas and storage of liquid methanol. Simplifying a gas to liquids process by combining multiple steps into fewer reactors leads to increased yield and efficiency, enabling less expensive facilities that are more easily scaled. [12]
