A hypothetical question to ponder:

Assuming I could get some land to grow stuff on (e.g. big allotment), could I realistically grow and process my own biofuel cheaper than forecourt prices?

I was thinking something like oilseed rape would be a good candidate (anyone know of a better one?) which would then need harvesting and processing to a point it would be suitable for a clanky old diesel.

How much land would I need to grow about 2000L worth a year in the north of England? How much processing would it need and can this be done 'in the shed'?

It would neatly sidestep fluctuating oil prices, taxation (tax free for first 2500L a year iirc), and be true zero net emission motoring (if you like that kind of thing).

As an afterthought are their any oil crops that have useful 'waste' products that could be sold on to make it more viable?

370-760 litres of rapeseed oil per acre, apparently.

You'd need a lot of land roughly 600 US gallons per acre from the very quick google i did, of course one answer would be for the gov to make farmers who leave land dormant and claim EU grants to leave it that way to grow the stuff that way it would affect the food supply as mutch but that's too complicated.

Yeah, you'd need around four acres to do it constantly (since you can't grow the same crop on the same land year after year) plus you'd probably have to get someone to process it for you. Not sure how much that would cost and whether you could still avoid the tax.

This covers the tax change to make it free which as far as I can tell hasn't been revoked.

It's amazing the difference in googling 370-700 litres or 600 US gallons per acre laugh

Wikipedia seems to suggest 102 US Gal / Acre for rapeseed but then in that article it also says 150 US gal / acre.

Assuming 4 acres is what is needed = 16,000 sqm = 126m x 126m. Hmm that's a BIG allotment.

Land price appears to be the killer. Nearish to me (Merseyside) it seems to be about 10K for 400sqm = £400K for 4 acres! That seems a bit steep. I suspect I don't need planning permission or certainly not in the same way as someone wanting to build houses. Might be able to get it a lot cheaper in that case.

A bit more reading suggests land not traditionally considered arable can be used for certain biofuel crops but their yield is lower. Might not be a problem if the land is considerably cheaper.

Whatever happened to the top gear fuel crop anyway?

You'd be better off growing food and using the money you save to buy petrol.

Bit more enjoyable too I imagine.

Already doing that in a limited capacity - anything that grows unsupported in the garden without dying I consider suitable for its environment and should be encouraged. So far only the rhubarb has taken smile

Although delicious for a more balanced meal I need the sugar cane and custard plant worked out.

Additionally the OH is campaigning me for a chicken pen (an Egloo if anyone has heard of them) to rescue battery hens, which apparently start laying again if given reasonable treatment.

or just using your land to grow whatever is easiest/worth the most at the time, and spending it on fuel!

That land price quoted above surely isn't for agricultutal land?

Up here it's £3k-5k per acre.

No its not. I couldn't find prices for agricultural land.

£20K for my own indefinite fuel supply does sound more in the realms of sensible.

The more I think about it the more I need to convince the OH we need to buy a farm. Loads of space for her chickens or whatever animal needs rescuing at that point in time (cats, dogs, rabbits, chickens, sheep etc), loads of space for growing fuel and idea loads of space to store cars biggrin

And agri land lets you get a holding certificate which lets you buy red diesel, build workshops (garages) etc without planning permission etc.

And you can have a dirt track going round the outside of your fields for a farm racer.

DO IT!

You can't grow crops on land all the time, it has to rest every few years, that's why land is left dormant.
And that's before you get into biodiversity etc.

See, additional benefits! This sounds like the perfect solution!

So where do I find agri land going at sensible rates? Or should I just hunt out a small farm?

If you only need a few acres find a biggish farm in a location that suits, speak to the farmer, explain you just want to buy some land for a small holding and see how you get on.

Found some land for sale nearby (bout 3 miles from work) but its 18 acres and they want £90K for it. Which works out as £5K/acre which doesn't sound too bad.

It's class 1 whatever that means confused

Something to do with quality for arable use.

Do you need 18 acres? That's a reasonable sized field, 72,000m2 (270m x 270m)

I don't know how agri land price varies by region tbh, up here 5k/acre is top-dollar. My mate just bought 5 acres of rough grassland, suitable for grazing, for less than £10k.

I've thought about this as I have access to about 10 acres of land I just don't know how easy it would be to turn the crop into diesel.

TBH I don't even need 4 acres, this was all just a thought on if biofuel was a realistic prospect. Seems like its definitely worth more research and investigating, especially from the aspect of somewhere to store, work on and play with some nice machinery.
