We make our rDME from renewable feedstocks 


Oberon was the first company to build a commercial scale plant to make renewable DME. 


DME itself (dimethyl ether, or CH  OCH  ) is a clean, colorless, non-toxic gas that is easy to liquefy and transport. At standard temperature and pressure DME is a gas, but it can be liquefied under moderate pressure, similar to LPG for storage and handling.


rDME can be blended in with LPG up to 20% without changes in handling procedures. We also support and supply applications ranging up to 100% rDME, such as in transportation, for equipment modified to use this flexible fuel. 



Oberon’s technology: making rDME from waste

We can use many different types of renewable, organic wastes including wastes from biomass, agriculture, municipal, and cellulosic sources. We can also produce rDME from syngas or renewable methanol.


We built the world’s first commercial scale rDME plant

Our ‘Maverick’ plant started making rDME in May 2021, and has a capacity of 1.5 million gallons per year. This milestone unlocks Oberon’s ability to reduce emissions from transportation today, while accelerating the development of the hydrogen economy and a net-zero carbon future.

This plant was brought to life with the generous support of the State of California, and created over 10 full-time local jobs in the community.

Oberon has completed design work for our second and third production plants, each with multiple times the capacity of our first plant, with startup planned for early 2025.


With over 30 projects under development, we currently estimate over 200 million gallons per year later this decade.

Many-fold capacity expansion by 2025; more to come
