There are many, many types of alternative fuel technologies that convert or develop existing engines or other energy producing mechanisms to use non-traditional fuels. However, there are a few forms of technology that are frequently required to utilize alternative fuels with existing technology.
- Fuel pumps - many alternative fuels exist at a viscosity or state of matter (i.e. solid at room temperature, rather than a liquid like traditional gasoline) that is incompatible with existing fuel technology in most vehicles or heating systems. Fuel pumps are often required to adapt an engine to take alternative fuels. Fuel pumps can also be paired with fuel injectors to assist in the movement of fuel around the engine, or to use the fuel more efficiently.
