Conventional LPG supply comes from natural gas processing and crude oil refining, but the sector is developing more renewable and lower-carbon options. Bio-propane (often called bio-LPG) has been produced for more than a decade, typically from refinery processes using renewable feedstocks – often vegetable oil – instead of fossil.
The problem is making enough of it. The demand for bio-propane is higher than the supply, which raises the price and makes negotiating supply contracts more complicated. However, the production is projected to grow significantly, as companies invest in new or expanded production facilities.
Dimethyl ether (DME) and renewable DME (rDME) also continue to attract attention. They can be blended with LPG in certain proportions, and, depending on the application, may be used within existing infrastructure with limited changes. One practical consideration is material compatibility, as DME/rDME can be tough on certain seal and gasket materials used in standard LPG equipment.
The World Liquid Gas Association (WLGA) continues to support the progress of renewable gases through initiatives like the Global Science Conference, held during Liquid Gas Week in Rio de Janeiro in September 2025, to help new solutions reach technical and commercial maturity.
