We’ve Arrived at the “Blend Wall”
The Energy and Commerce Committee of the US House of Representatives has been holding hearings this week on the Renewable Fuel Standard (RFS). It’s otherwise known as the ethanol mandate, although it covers biodiesel, as well. These hearings are timely, since at least two bills have been introduced to reform or repeal the RFS. During Tuesday’s session Rep. Waxman (D-CA) referred to the “gasoline blend wall, which may be around the corner.” In fact, a review of current gasoline sales and this year’s ethanol target confirms that the ethanol “blend wall” has arrived, at least for some of the nation’s refiners. That explains the urgency of the debate about the future of the RFS.
The blend wall is simply the threshold at which the RFS requires more ethanol to be blended into US gasoline than the quantity necessary to dose essentially all of it with the maximum 10% ethanol content for which most cars on the road were designed. Because the Environmental Protection Agency, which administers the RFS, has been unwilling to exercise its flexibility under existing law, the fuels industry must now choose from a set of unattractive options: It can limit mainstream gasoline to 10% ethanol content and absorb substantial RIN costs (see below) or penalties for failing to blend the required volumes of biofuel. It can produce less gasoline than the country needs, or export more of its production, to reduce its renewable fuel obligations. Or it can produce higher-ethanol blends such as E15 and risk the integrity of millions of cars and large portions of the country’s fuels infrastructure, including all but the newest gas station pumps and tanks. All of these choices affect the price consumers pay at the pump.
By now you have probably heard that the EPA has postponed issuing guidelines on whether to allow ethanol blends of higher than 10% into the gasoline pool. Going up to 15% ethanol blends would allow ethanol producers to put a lot more of their product into the market, which is currently bumping up against the limits of the current 10% ethanol blend allowance. Ethanol producers and proponents have assured us that the higher blends will not damage engines. Small engine makers and boaters are very worried that the higher blends will damage their engines. In fact oil companies, having been mandated to use ethanol, are now facing a class action lawsuit over ethanol blends damaging boat motors. Even the auto… Continue»
