I was reading about BioGas and Home BioGas is a very attractive product that seems to be working - any experience?

I've never heard of either. I'll do some reading this week.

@neilsondhi, it's taken me a while, but I've contacted them to find out more. It really looks like an interesting product.

Hi Mars,

When I looked at this when it was first posted, it would appear that the daily production of gas was about enough to cook a meal on a gas hob.

@derek-m, it does look cool - I'd consider using it to make home beer brews making them more environmentally-friendly. We eat a lot of veg and have a ton of green waste so we'd have no problems keeping it "stocked" and powered.

I think an anaerobic digester has to run warm, and it uses some of the available organic material to keep itself warm.  For that reason, it works better at larger scale in the UK.  Maybe you could get scraps from other households to help out!

Dale Vince, cool founder of Ecotricity, has a great blog - saying the UK could create enough biogas to run most of our housing stock, assuming it was upgraded a bit and using most grazing land in the UK to make grass fed to biodigesters.  As gas prices are now so high I'm sure this is being worked on.  I think he said ~1/2 acre of grass makes enough biogas for his average "improved" house:

Hi @robl

I think that this is a very good idea. To supplement the supply of grass from fields, the grass cuttings from lawns and parks could also be collected and used. I feel certain that other organic waste may also be usable.

Areas designated for growing the grass could also contain solar farms or wind farms.

At last some joined up thinking. 😊

There is one of these sites near us. 

I use to drive past it on the way to work. 

Never smelly and small enough it just disappears. Generates electricity

Biogas has potential but I think most installations will choose to convert it to electricity for export rather than to export gas itself.

Sometimes, they go bang spectacularly, as at Harper Adams University,and elsewhere.

The fact that it is quite easy to produce an explosive mixture, is one of the reasons why it should be done using a controlled industrial process.

Whether it is exported  as gas or electricity is not as important as the fact that it can be stored in bulk, and is therefore available when required, which is not always the case with wind or solar.

For a general read and background on the technology and it's potential you could look at this company: https://bennamann.com/.

There are videos that are quite informative, I know the company well and the science is very sound.
