How much does Geo fuel cost per litre and does it harm the atmosphere?

Question

Scientist have thought of a new way to feul cars .... by cereal crops and i want to know how much it costs per litre and if it harms the apmosphere

Answer 1

cost  about 25 pence per litre at the moment until they get the tax on it and also its only diesel, alternate by product should be water as in hydrogen fuel, so no CO2

Answer 2

i depends on your area but in Ellesmere Port cheshire I have seen it for sale at 84p a ltre and owner of garage said he would only use it on old engines not new ones?

Answer 3

Perhaps Geo fuel is a brand name?

The generic term for farmed fuels is BIO fuel.

There are 2 main types, alcohol (ethanol) and oil(Bio Deisol)

Obviously the bio deisol is only good for deisol engines. Whereas the ethanol is suitable for petrol engines.

Generally it is ok to mix up to 10% ethanol with petrol and to use that directly in a normal petrol engine without having to make any changes to it. (it will boast engine performance by a tiny amount).

With slight modifications to the fuel intake systems, 100% ethanol can be used in petrol engines. For a time over 80% of Brazil's cars were run on ethanol. The handling and storage of ethanol is not very different to that for petrol, so no great infrastructure costs needed to make the change at the delivery end.

As to combustion products, H2O and CO2. But as the CO2 was removed from the atmospher by the plant used to make the fuel from just a couple months before, there is no increase in green house gasses. But as the ethanol is the product of fermentation of sugars there is an excellent opportunity to capture additional CO2. One of the byproducts of fermentation is CO2. It is given off almost pure and so easily captured for disposal by whatever clever way we come up with. MUCH cheaper than extracting it from flue gasses at a power station. So an ethanol based transport system using bio ethanol, could be a big CO2 removal enterprise at little cost.

Bio deisol also does not add CO2 to the atmosphere, but it does not have the advantage of that extra CO2 removal option. (Bio Deisol from waste fats and oils is a winner though because all of that would have ended up just decaying in some land fill.)

As to cost, ethanol and bio Deisol are already cheaper in some countries where fossil based fuels are expensive or heavily taxed.

Here in the remote areas people are already making their own bio deisol and saving a fortune as it comes in free (apart from labour) or if you buy it at half the cost of deisol.)

Ethanol never quite seems to make it into the fuel tank! For some reason the output from the average home fermentry/stil seems always to fall short of expectations, and the cheary unsteady somewhat incoherent  interviewees can't offer any explanations.
