That's our energy balance. From my blog:

Kumar,
Thats sweet. Didn't know you were doing that kind of volume. Wish someone up here was, I can't find anyone doing it at all near Billings.

PB, what's truly crazy is that we are NOWHERE NEAR as efficient with our energy usage as I'd like to be. We don't even use boilers for our heating. Yes, we certainly will eventually, but it's pretty amazing that we are currently operating at nearly 3 times the DOE rate, and a testament to what could be. Long live UFOs*!

What about the fossil energy in the methanol and KoH or NaOH? Are you accounting for that?

Aha! A flaw in my formula- if anyone can help with some data on that embodied energy, I'd appreciate it. Kumar Plocher Yokayo Biofuels Fueled for Thought blog .........../ \.............. fueling / R \ evolution since 2001 '''''''''''''/____\''''''''''''''''''' Sustainable Biodiesel... |

If you COULD get to use that generator you could also use the waste heat from it to help heat your process. That would make it even more effecient. (CHP - Combined Heat & Power)

That sounds good, but what about the energy inputs of methanol, catalyst, water, etc?
Chris oops, i posted this directly from my email, didn't see that'd already been mentioned. I believe that Lyle at Piedmont Biofuels did an energy calculation on their fuel at the coop a few years ago, came up with a number similar to yours. I don't have the numbers on these, but if I get a chance, I'll post. |

Thanks. I remember him saying something like 7:1. I don't think methanol and lye would lower us that much, but we're certainly in the ballpark. These numbers really do showcase that the recycled fryer biodiesel industry is a different beast than the soy people. My goal is now to double our energy balance to over 17:1. We are doing algae research with some partners- a wild strain growing on sewage. Because it's a wild strain, it's *only* projected to produce ~900 gallons/acre. Gee, I wonder what the energy balance on that will be...

Methanol has a BTU content of 62,800 BTU/gal, so that's pretty straighforward to account for.
This is FAR lower than gasoline by the way. If you want to be "fair" and "sophisticated" in your EROEI analysis, you would count the BTU content of the glycerin byproduct in FAVOR of your EROEI. That's how they make the EROEI numbers look somewhat positive on ethanol. They count the spent grain mash BTU's on the positive side of the ledger. Keep in mind, it all gets fed to cattle, but it does have some "energy" value. You could make exactly the same argument for the glycerin since cows are reported to love it! We too can be sneaky and underhanded if we wish. HTH, troy |

Its not that straightforward, since you would need to count the energy input to make the methanol and KoH. That will be much more than the BTUs contained in it. I think most methanol is made from natural gas. KoH has no BTUs (I don't think it burns) yet still requires a lot of BTUs to make it.

I was thinking about this earlier today, and it's a really tough thing to include MeOH, KOH, and glycerin, which should really all be accounted for. Assuming the glycerin is being put to good use (broken up, some of it burned as fuel), even if the MeOH and KOH negatively affect the energy balance, I think we'll still be in the 7+ range.
