There has been much more focus on the “crumbling infrastructure” related to how vehicles travel on the roads and bridges in the United States. But what about the infrastructure that supplies the 12 million barrels of transportation fuel that is required every day? And what are the critical considerations for any new fuels introduced to the market—especially how they must fit into an existing infrastructure?   The podcast examines the research findings in a Fuels Institute report that evaluates the U.S. supply chain, how it works and what limitations/weaknesses exist at each point to accommodate diverse fuel specifications and achiev­ing higher rates of biofuels penetration. Understanding the fundamentals of this complex system is essential for anyone considering introducing a new product into the market or adjusting market dynamics for any reason.
