bit of an old thread...
just wondering if you got anywhere with this Ivan ?
I'll need a new van in a few months... and I'm tempted to buy a petrol one and convert to cng....
I'm thinking pretty soon it'll be cheaper than the veg oil I run on now!
(and I'm doing lots of miles now too)

Yes, and no. My car is running on LPG at the moment, with a tank in the spare wheel well. I have the kit for CNG conversion, and a plan....My calculations suggest that if the Methane regulator is set at 2bar output pressure rather than 1bar (the LPG regulator pressure), then the LPG ECU will not know the difference if I switch between regulators (which is easily done with 12v solenoids). That's the plan, anyway!
The setback I had, was that I seem to be carrying big PV panels in the car most weeks, which requires all of the load space with rear seats down. Consequently, I planned to fit the tank in the rear footwell (children are still too small to require legroom), but my CNG tank diameter is too big, so I cannot do this. I really need a small diameter CNG tank but so far haven't found one.
I must get round to doing somthing about it.......

Now there is a solution for Ivan, a big plastic bag on the roof! |

It's slowly starting to be implemented. http://www.cngservices.co.uk/crewe-cng-filling-station/The rate that AD is being implemented, food waste will eventually have a positive value. |

I agree with you Ken, running cars on Methane is not very different to running on oil, a diversion from the task of shifting our transport to sustainable leccy power.
Desperate
Id have to disagree. It is said that agriculture is responsible for an estimated 14 percent of the world's greenhouse gases. A significant portion of these emissions come from methane, which, in terms of its contribution to global warming, is 23 times more powerful than carbon dioxide. Its a natural by-product of the bacteria in the gut and is also released during the treatment of our own sewage. If this methane was captured and used as fuel, the waste product would be CO2, which in turn is absorbed by the grass being used to feed the animals and us. Therefore, completing the Carbon Cycle and being pretty much carbon neutral, if we use solar electric to power the digester's/compressors  So I cant see how is no different to oil ! |

food waste will eventually have a positive value.
If you include waste cooking oil, then it does already have market value, perhaps 30-40ppl for decent but unfiltered oil. Five years ago it had a negative value if anything, with distributors charging to collect and dispose. |

A number of years ago people couldnt give it away. We used to collect it and fuelled a Lister CS engine on the stuff almost 24/7. As long as it was left running there was no problems. The heat generated, helped in the processing and filtering of the oil prior to burning. The electric fed into the batteries. All for free!! The only draw back was having to switch over to diesel to start and stop the thing. You would need to be a very strong individual to start a cold Lister on 100% veggie oil !!

old thread bump (again) any further along Ivan ? I wimped out last time and bought a diesel van and twin tanked it for veg oil.... but now I need another van... so I'm looking around again... thinking about gas again.... veg oil is starting to get expensive (I buy all mine in) and it looks like the price will only go up!  |

No, I keep meaning to get it finished. I've got two problems though:
1) My passat estate is just the right size for carrying PV panels - with only a few mm excess width, and requiring the seats down. If I put a gas cylinder in the boot, I won't be able to do this, and at the moment, I seem to have to carry a lot of PV about (won't be for too much longer....). I'd hoped to put a tank in the rear footwell of the car, but the tank I have (70litre) is too large a diameter to go in the available space. I need something more like the diameter of an oxygen cylinder, but not found a supplier yet (there doesn't seem to be anyone carrying CNG tank stocks in the UK
2) I've been distracted by the recent PV incentives. Should get back to normal soon!
