Suburban Propane Partners LP and Iwatani Corp. of America will collaborate to advance the adoption of low-carbon alternative energy solutions across multiple applications in the propane market, including propane blended with renewable dimethyl ether (Propane+rDME). The companies announced an agreement May 23, also highlighting their collaboration on advancing investments in hydrogen infrastructure and transportation services in the United States.
Suburban Propane and Iwatani plan to work together to test and evaluate material compatibility, equipment performance, and emissions profiles of residential and commercial appliances, forklifts and on-road vehicles at varying blend levels of Propane+rDME.
The partners will also explore investment and development opportunities to expand the distribution network for hydrogen in the United States. Iwatani’s parent company is Japan’s only fully integrated supplier of hydrogen with the largest share of hydrogen production, distribution and hydrogen refueling stations in Japan, according to the announcement.
