DME and Its Future rDME

What is DME?

  • Dimethyl ether (DME) is a synthetically produced alternative to diesel. Under normal atmospheric conditions, DME is a colorless gas. It is used extensively in the chemical industry and as an aerosol propellant. Dimethyl ether requires about 75 pounds per square inch (psi) of pressure to be in liquid form. Because of this, DME's handling requirements are similar to those of propane.

  • DME application

  • Because of its lack of carbon-to-carbon bonds, using DME as an alternative to diesel can virtually eliminate particulate emissions and potentially negate the need for costly diesel particulate filters. 

  • The Ultimate Goal: rDME

  • Renewable DME is the ultimate goal of our Green Energy Strategy. Using bio-gas, Bio Friends and H&H will produce rDME to achieve carbon neutrality.
  • H&H's partner: Bio Friends and its DME plant

  • Bio Friends completed the construction of 5,000 TPY DME commercial plant in Boeun, Chungbuk, South Korea in July 2020, and is producing DME for chemical and agricultural use and hydrogen production
  • Bio Friends conducted a test operation in September, and began its commercial production in October 2020
  • Based on this, Bio Friends and H&H are promoting various DME projects including rDME all over the world
  • rDME to Green Hydrogen
