How to Grow Fuel the Real Way, No Subsidies Required

02/04/2015 12:50 PM

Here is completely (as near as I can see), the answer to removing ethanol production from a source based on cereal grains (as far as fuel ethanol, or maybe even beverage ethanol distillate).

It is not intended to be a "commercial" for the Alginol company, but it demonstrates their efforts for seven years, their committment, and the progress they are making.

The fact that a high ethanol yield per acre is made, and the remaining biomass is converted into gasoline, diesel, and jet fuel is remarkable and noteworthy.

quite interesting. basically its solarto be a success they'd really need to ramp up their acreage, thats doable. I'm no fan of ethanol but it is a legit fuel. I never saw that much on their biodiesel but if it performs I could see them teaming up with any number of partners to get in the market

When one considers the carbohydrate content of most algae (>25% up to 40%) it would seem to be a viable feedstock for ethanol production that can easily replace corn. Algae should require less actual water consumption (although water utilization can be high), as the water is easily kept from evaporating in the bag system, and is also able to be recycled into the next run.

Kind of a sideline fan of using cattail grass for ethanol production myself.

Very high ethanol production per acre plus uses swampy land and can be set up where the land is also used for sewage, bio remediation work or wildlife wetland applications in locations that normally would be way too wet or poor of soil/water conditions for any normal crops.

Impressive. If you're out of whisky and feeling cooled, you just sip on your gas tank a little and it should make you get going. A blood alcohol level of 0.05% is euphoric

But the algae could be detrimental if they are invasive or someday it will evolve.

Doesn't algae also produce a large amount of atmospheric methane? If the climate change boys are right, then according to research, we should also get rid of the hydro power industry, as the reservoirs used produce over 20% of the methane currently being measured...

Who measures the methane, and what did they eat last night? I don't really want to know.

Algae has growth stages/phases as follows: Inoculation/Induction, Linear, Peak Quasi-Static, and Die Off. The situation in most ponds, lake, reservoirs,etc. where water is just sitting around, is stage 3-4 where the algae is somewhere between static level and die off. The dying algae basically fall to the bottom and rot, thereby bacterial activity produces the methane (also called swamp gas). Algae in waters where the sulfate ion is present above (I think) 50 mg/L (ppm) are not known to be methane producers, but below that figure (sulfate removed) methane is produced, and it is due to an alternate bio-pathway in the organisms.

The aquaculture of algae can be in a -semi-closed (bag) system, or an open system.

Open systems are subject to all manner of problems when/if wild strains take over.

Semi-closed systems would not experience that problem as often.

All algae production nees to be operated in the higher linear growth phase to maximize production, minimize die-off, and to ensure the controlled balance between sugars, higher saccharides, oils, and proteins in the product organisms. This appears in yield branching ratio during production of the sugars for ethanol, with the remainder going into pyrolysis to make gasoline, diesel, and jet fuel.

The highway patrol would not want ethanol to become fuel someday.

What was the source of that picture? It looks like my nephew!

Someday? Ethanol, in case you failed to notice has been in our gas tanks for quite a number of years now, and is presently about 10% of gasoline. We could also blend gasoline with anhydrous ammonia (with small modifications of the tank to handle pressurized operation above what little there is now). Talk about finding or noticing a fuel leak! WOW!

In Brazil, they changed to automotive fleet to accept up to 100% ethanol, how does that grab ya?

Here is the latest new factoid on algae: a way to make biodiesel and jet fuel from the same organism: Isochrysis. Isochrysis is currently only grown in small lots to feed crustaceans, I think. At the current rate of production, it might cost $10,000/gallon of fuel produced, but there is hope in scale up - the organism will grow rapidly. It produces some FAME's (biodiesel), but also contains high enough levels of Alkenones (C29-C39 or so) to make the extracted "oil" a black greasy semi-solid. Olefin metathesis converts theses long chain keto-olefins to shorter chains consistent with jet fuel.

This last link is all about olefin metathesis, includes a description of Grubbs' Ruthenium catalyst that is central in exchanging butene with the double bonds in the Alkenone molecules.
