Dimethyl ether (DME) is an organic compound with the formula CH3OCH3

DME is an ideal carrier for hydrogen fuel

Dimethyl ether has a number of qualities that make it perfect for transporting zero-emission hydrogen fuel to power a new generation of fuel cell vehicles that are just beginning to hit the road:

  • DME is particularly dense in hydrogen, with six hydrogen atoms in each DME molecule.
  • Converting DME into pure hydrogen a simple, inexpensive process compared to natural gas to hydrogen conversion.
  • DME liquifies at low temperatures, making it much easier to transport than pure hydrogen.

These qualities mean that the roll-out of DME-powered trucks can also accelerate the expansion of hydrogen fueling infrastructure.

As trucking fleets begin to use DME as a fuel, the same equipment and feedstocks can also be used to bring DME directly to hydrogen fueling stations, where it can easily be converted to fuel those vehicles as well.

With DME engines and trucks in development now, and with hydrogen vehicles pushing into the market, these two fuels can quickly become natural allies.

A more detailed description of the potential for DME to play a dual-role in a cleaner, zero-emissions transportation future is described in  our recent Medium post.
