Been thinking about a small scale AD plant. Bare with me! We dont have any livestock and are a cropping farm only. We have solar power already and dont really have a demand for the power (although heat may be useful) We do have a few gas mains running through the farm although not near our buildings. What are my options or is it just completely uneconomic.

Totally uneconomic on crop fed. You might make it stack up on slurry + waste silage, but only if you use the electricity and the heat to good purpose. You will get more electricity per acre from your solar by a long way, and far less work, maintenance costs, haulage and the rest.

Been having similar thoughts, but small enough to cover our winter demand when solar is down (10kw/h Average)

Speaking to AD owners, if you think you can justify the upfront cost, just double it to cover maintenance and running costs. 👎

Anyone going seriously down this route is welcome to come to our farm and see how we have had to modify our AD to get it to work, and reduce maintenance costs.

3rd World biogas production... Saw these in the early 80s in action in India, but possibly not quite what the OP had in mind.... :)

I helped in the build of the gasholder in this one in Malawi in 1977. It made gas for cooking the farm workers food. Ran on cow manure (got a hyaena stuck in it after I left)

Yes, they do work. I have seen them in Africa and India. In India there are many but some become silted up from crop residues and the Ladies refuse to clean them out. So no longer operate.
Simple process can power a simple ring gas burner for domestic family or small village community cooking. A few cows can provide power, digestate spread on adjacent land to feed grass for said cows. Perfect cycle. Better than slash and burn or charcoal production.
So cows can save the planet!

They work well in warm climates, but I can’t see the bugs surviving British temperatures very well without some serious insulation/ heating, which would no doubt alter the viability somewhat.

one of my customers has a small scale one, it was financed by the Scottish gov many many years ago, they only used it for cooking and heating the house,
 

Top cereal and oilseed growers honoured at the Yield Enhancement Network Awards 2021

Despite an average growing year for most crops, many growers managed to go above and beyond their predicted max yields, with Lincolnshire grower Tim Lamyman taking the top spots for his wheat yields and his world record breaking winter barley yield.

The highest cereal and oilseed yields achieved at harvest 2021 were announced at this year’s Yield Enhancement Network (YEN) Awards on Wednesday 24th November at the Croptec Show. With award presentations by Tom Bradshaw, Vice President of NFU, 24 farms took home the evening’s top awards for highest yield and highest potential yield achieved for wheat, winter and spring barley, oats, and oilseed. The 2021 winners came from all corners of the UK, as well as from as far afield as Finland and New Zealand.
