Cogeneration and ethanol production

I am not the biggest fan of corn ethanol. But I am the biggest fan of cogeneration, also known as combined heat and power, or CHP (well, maybe the second-biggest fan). It is probably the single most overlooked strategy for sharply cutting greenhouse-gas emissions while reducing overall energy costs.

Now a new EPA report finds that running an ethanol plant on natural gas CHP can, with the right design, result in negative net CO2 emissions (click on figure to enlarge).

Important caveat: "Impact of Combined Heat and Power on Energy Use and Carbon Emissions in the Dry Mill Ethanol Process" (PDF) does not examine the energy consumed (or emissions generated) from growing and harvesting the corn or from transporting the corn or ethanol. Still, with CHP, corn ethanol can actually generate significant CO2 reductions compared to gasoline.

If Congress is serious about promoting ethanol in a manner that actually reduces GHGs, they should require all new ethanol plants to cogenerate.

Keeping power broker’s hands out of the cookie jar

[[editor's note, by David Roberts] In addition to the updates below, I wanted to make it clear that this post does not meet Grist's standards. Had I been around (I'm on vacation), I would not have published it. I've sent Khosla a personal apology, which he has graciously accepted.]

[UPDATE: Dave has requested that I update this post, which I have done below with some clarifications and added links.]

Vinod Khosla recently posted this comment titled: "Numbers Matter Here: Support your statements" over on Joseph Romm's post.

There is nothing wrong with an individual investing in a product that he or she believes in. The problem arises when perversely wealthy individuals try to further line their pockets by putting their paws in our pockets, using our tax dollars to fund their get richer schemes. Get your hands out of our pockets and keep them out, you money-grubbing rascals.

When Vinod Khosla takes E-85 fueled car trips with the likes of Sen. Tom Daschle, he is quite obviously lobbying for support of ethanol. Our government process has become seriously compromised thanks to wealthy special interest seekers buttonholing politicians to line their own pockets. It is a two-way street of course, with the senator hoping to receive campaign donations from those who want his support of ethanol. There are almost 35,000 registred lobbyists in Washington. How many of those lobbyists get to ride in a car with a Senator?

Vinod, that may be how business has been done in India but that may also explain a lot of India's past problems. We need to fix the problem here before we end up like India (the country you bailed from).

[UPDATE: The above comment has been taken by some to be xenophobic (and therefore racist). I am referring only to the Indian government's low CPI score (corruption perception index). I should have been more clear that it is this political corruption that Khosla has left behind. Commenter pangolin read my intent correctly here:

The OP points out that the rise of ethanol as a motor vehicle fuel is the product of rampant political corruption and crony capitalism in the US Federal government. He vaugely mentions the well documented rampant political corruption and crony capitalism that has been widely acknowledged to be preventing India from solving it's many problems.

All bloggers eventually get into hot water when what they write is misinterpreted or flat out wrong, as many of my fellow contributors can attest. It comes with the territory. And yes this is a harsh critique. Market distortions by special interests are wreaking havoc on the the environment. My apologies to anyone offended.]

As a self-professed life-long Republican, you helped put the most anti-intellectual, anti-environmental, ham-fisted president in the history of this country into office who for the first time in our history took us to preemptive war and on erroneous data at that, essentially by accident. We may never recover from his legacy. Based on that decision alone I would not trust your judgment any further than I could throw you.

Now let's talk about your numbers and especially about the assumptions made to get them.

PNG agrees to let palm-oil producers raze rainforest

Everyone at Bali cheered when the Papua New Guinea delegate dissed the Bush team:

We seek your leadership. But if for some reason you are not willing to lead, leave it to the rest of us. Please get out of the way.

Oh, snap! [Sorry, couldn't resist one last 2007 Daily Show-ism]

Now comes the heartbreaking news:

Unlike the U.S., European governments are cutting back on agrofuel goodies

European biodiesel makers have entered a rough patch. The price for their main feedstock, rapeseed, has risen more than 50 percent since the beginning of the year. But the price of the final product, biodiesel, has plunged, because producers are churning out far more biodiesel than the market can absorb. Similar conditions hold sway among […]

A new piece on the insanity that is U.S. ethanol policy

I have an article in Salon on the insanity that is America's ethanol policy. The new energy bill sets this country on a path to finish the assault on the world food supply begun by the (even lamer) 2005 energy bill. As I explain, our ethanol policy does not help fight global warming, but it does threaten food supplies:

In just the past two years, food prices have jumped 75 percent in real terms ... The Economist points out the amazing statistic that "the demands of America's ethanol program alone account for over half the world's unmet need for cereals."

By law (the 2005 energy bill) we are going to increase corn ethanol production at least 50% over the next few years. And the new energy bill will probably require corn ethanol to triple from current levels! But current levels are already bringing havoc down on the global food market.

Boat aims to set speed record … powered by human fat

Here's a nice PR gimmick (and by nice, I mean totally disgusting): power your monster "eco-boat" with biodiesel made from human fat:

You can also make biodiesel from tallow (animal fats), fish oil, seaweed and algae. In fact, in an extraordinary show of dedication to the project, the skipper, Pete Bethune, underwent liposuction, and the fat (all 100ml) was used to make a small amount of Biodiesel for Earthrace!

I think this mostly shows an extraordinary dedication to clever marketing. Unfortunately for the earth, Bethune isn't all that chubby, so he enlisted a few "big, fat people" (his words) to squeeze out four gallons of biodiesel. All in, this represents about 0.06 percent of the fuel Bethune will need to set the "Round the World Speed Record by a Powerboat."

Don’t tell Canis!

This is one of those stories where you don't know whether to be hopeful or depressed after reading it. Like drug addicts who will try snorting every powder in the house, we seem to be willing to subject any substance on the planet to the real acid test of our age: Will it help us keep carburbia going?

Notable quotable

“I really would like to vote for this bill because we desperately need an energy bill. The world and particularly the United States faces a real challenge on energy in the future. But I cannot vote for this bill primarily because of the corn ethanol mandate. A recent article in The Economist noted that our […]

The ethanol boom could trigger a ‘tipping point’ in the Gulf

Days after Congress voted to ramp up the government mandate for corn ethanol, bringing it to fully three times current production levels within a decade, we get bracing news from the Gulf of Mexico. Here is the AP: The nation’s corn crop is fertilized with millions of pounds of nitrogen-based fertilizer. And when that nitrogen […]
