John Lewis trucks running on biomethane

[jerseycowsman]

does anybody know where I can find more info about this. We will be needing new slurry storage soon, if we can store it and use the methane for the tractor or sell it, that would be good. But can’t find anymore info other than this article about it

Never knowingly undersoiled – John Lewis trucks to run on cow manure

Retailer’s fleets will use carbon neutral renewable biomethane

New Holland have just launched the first (production) methane powered tractor. As seen in the YouTube video, not the concepty looking thing but the regular looking tractor at the end of the video.

Thought they said methane came off or out of livestock before manure captured for this?

Not new.

Not new.

No, certainly not. But it is the first production tractor that's available to buy.

How much more??

Don`t think it`s as simple as that.
@sjt01 is the man who knows about getting goodies out of shite

Look up Methanogensis

Certain microbes that are in decaying organic matter at a certain stage make it.
An example is flooded paddy fields... ( vegetarians note) they actually give off tons of methane ...literally ...not many people know that.

Anyway , I guess bits of silage, hay or straw in fym and rotting down in'storage' would make methane at least...

We costed it up a few years ago. The cost of getting the CO2 and H2S out and converting a tractor made it more expensive than red diesel but cheaper than white. Talk to Marches Biogas about their Agridigestore, also there have been some past threads on here about Bioelectric digesters. If you are not generating enough gas for electricity generation, then you may well still have enough to run a boiler for dairy heat, domestic and office, I think RHI may still be available.

Not new.

Was being done probably 40 years ago, petrol tractors converted to CNG, or better still diesel engines with spark ignition as you really need compression ratios of 16:1 or 17:1 for maximum effectiveness/horsepower.

Price wise? I'm not sure.

i thought storing methane was a problem as it needs very high pressures to liquefy? has this been overcome?

Just high pressure gas tanks. It needs cryogenics to liquify so not practical unless you are bringing a ship load from Saudi, and then they use what is boiling off to power the ship engines.

Classes as bombs on site will they????

Have a look at Jean Pain who was doing this 30 years ago with shredded wood powering his vehicle cooking and heating. All very simple with low pressure methane stored in inner tubes then for his vehicle the gas was compressed using a scuba compressor and scuba tanks. Lots of small scale methane kits available from South Africa.

40yrs ago doing things with turkey muck also?
Nothing new really?

Dont forget the humble sugar beet when considering methane production as the improvement in methane output of AD plants is supposed to be dramatic.

We find if you feed too much you can kill it quite quickly. At this time of year we feed 2.5 t beet, about 4 t maize silage, 7 t dairy slurry. Dare not go over 3 t beet over an extended period (hard won experience).

The future must be a consortium/cooperative of farmers (even 00's) getting together and building a large plant as opposed to multiple small ones.

Economies of scale would see upgrading biogas to CH4 which is then injected into the grid. It could then be removed at any point and compressed as CNG, then used as vehicle fuel.

Alternatively, upgraded to CNG at the plant and made available as a commercial gas station.

In addition, all the nutrients could be re-cycled.

Think gas has got to have scrubbers and other technical devices to be able to end use ,plus storage handling,hse ,etc etc etc.
