  • Big square baler harvesting wheat straw for production of cellulosic ethanol

    Though the Environmental Protection Agency has already ruled on ethanol-blended gasoline mixtures for 2018, that hasn't stopped ethanol advocates from pushing for a higher 30-percent blend for non-flex-fuel vehicles. The latest call for ethanol comes from corn-state ethanol refiners, farmers, and an ethanol-producer trade association, all of whom want the EPA to take a good, long look at raising the approved blend for standard "gasoline" from E15 to E30. Meanwhile, on the other side of the debate, two bills making their way through Congressional committees would cap ethanol blends at E10 for...

    Proposed ethanol cuts bring EPA up against Iowa's powerful politician

    Following years of debate, the EPA said earlier this month it will study the possibilities of cutting the amount of ethanol in the United States' gasoline supply. Since 2007, the Renewable Fuel Standard (RFS) has required growing amounts of ethanol to be blended into U.S. fuel supplies, with...

    EPA to study cutting amount of ethanol in U.S. gasoline

    Since 2007, the Renewable Fuel Standard has required increasing levels of ethanol in gasoline blends sold in the U.S. Most fuel stations across the United States no longer offer pure gasoline, with E10—a blend of 10 percent ethanol and 90 percent gasoline—prevailing. After years of...

For at least one carmaker--Ford--and possibly others as well, that turns out not to be the case: Different gasoline formulations are...

  • Non-ethanol gasoline pump

    Ethanol is a beleaguered fuel these days, with national availability E85 nowhere in sight, rollout of E15 seemingly stalled, and concerns over its full carbon footprint hotly debated. Most drivers pumping gas pay little attention to its ethanol content, which in several states may now be at 10 percent. Meanwhile, traditionalists seek out pure gasoline for older engines and those in motorboats, lawn equipment, and other offroad uses, which they claim can't withstand even E10.

    Bills To Kill Renewable Fuel Law, Ban E15 Ethanol Fuel Likely Doomed

    The addition of ethanol to gasoline has now been a political hot potato in the U.S. for more than a decade. Joined by cosponsors from both sides of the aisle, U.S. Representative Bob Goodlatte [R-VA] introduced two bills in February that together would eliminate the Renewable Fuels Act passed in...

But marine users in...

    Ethanol A Victim Of Change As Gasoline Sales Have Flatlined?

    Eight years ago, ethanol was going to let the U.S. grow its own vehicle fuel, reduce its use of gasoline made from imported oil, and boost energy security. How much have you heard about those themes lately? Not much, we'd wager. A lot has changed since the 2007 passage of the Energy Independence...

  • Big square baler harvesting wheat straw for production of cellulosic ethanol

    Could low prices be the key to making ethanol more popular? One Michigan filling station allows customers to change the ethanol-gasoline blend in their fuel. As customers "dial up" the amount of ethanol, the price goes down, WardsAuto reports. Other stations offer multiple blends, with varying amounts of ethanol at varying prices. Mike O'Brien, vice president-market development for Growth Energy--an organization representing ethanol producers--told Wards that lower prices will help ethanol-blended fuels gain traction with consumers. However, while ethanol blended fuels like E15--a mix of 15...

    Demand For Gas Falls, Gas Prices Rise: Blame Ethanol (And Congress)

    For fans of fuel efficiency, the New York Times has good news and bad news. The good news is: drivers in the U.S. are using less gas these days. The bad news is: that's driving up the cost of gas. To anyone who's taken Econ 101, that probably seems counter-intuitive -- mostly because it is. To...

    Ethanol Is Nothing New; E10 Gasoline Was Sold In 1930s

    Back in the 1930s, the United States produced the vast bulk of the oil it burned. It wasn't until the 1973 oil crisis that things like OPEC and fuel efficiency entered the U.S. consciousness. And it took a while longer for the phrase "energy security" to come along. That's what led to the concept...

    EPA Keeps Corn-Based Ethanol Mandate, Rejects Suspension Request

    Last month, the governors of eight states and almost 200 members of Congress asked the U.S. Environmental Protection Agency to suspend rules that mandate production of ethanol for use in gasoline. On Friday, the EPA said no. The request to suspend parts of the 2007 Renewable Fuel Standard came from...

    With flex-fuel cars that can run on E85 ethanol still a minority of the vehicles on sale, you might think ethanol isn't as important as some other future fuels.

    You felt the earth shake a week ago today when the EPA formally approved the sale of E15 gasoline, right? Oh, you didn't? Not surprising, really. No gas station in the U.S. sells E15 today, and it looks like it may be a while before any given driver sees the stuff showing up as one of several...

  • Corn Ethanol Pump

    When the U.S. Congress adjourned for the holidays on Friday, December 23, its departure sealed the fate of subsidized ethanol production. During its session, the Congress did not renew a tax break for U.S. production of corn-based ethanol that had become increasingly unpopular across a wide area of the political spectrum. The tax credit amounted to 45 cents per gallon of ethanol that was blended into gasoline. It had been in place since 1980. Corn lobby loses support As The Detroit News reported the next day, by some estimates, total subsidies to the ethanol industry may have reached $45...

    Ah, ethanol, that most political of alternative fuels. Farmers love it, deficit hawks hate it, automakers want it for flex-fuel CAFE credits but nowhere else, and environmentalists only want it if it doesn't suck up food supplies, use too much water, or worsen the carbon balance. Yesterday, EPA...
