Hi all, 

 

I am looking at the feasibility of replacing diesel generators with biogas
generators to power milk cooling centres in dairy co-operatives in Central
Uganda. The site that I am looking at for a pilot currently has a 26kW
diesel generator that powers 2 refrigerators and some auxiliary equipment
(lights, a computer etc) for 6 hours per day.

 

I have some questions that I hope you can help me with:

 

1. What would be an appropriate engine for generating from biogas at this
power? I am considering a dual fuel compression engine (for the advantage of
being able to rely on diesel if the biogas is down for whatever reason) but
not sure if this is the best idea? Does anyone know of any companies that
would provide appropriate engines for this application?

 

2. What are appropriate BMP, Total Solids and Volatile Solids numbers to use
for sizing the digester (currently assuming 380m3/tonnesVS, 25%TS and 85%VS
but want to check this is correct. The feedstock is 100% dairy cow manure
from zero-grazing cows in rural Central Uganda.)

 

3. Does anyone know of any reputable companies operating in the East Africa
area who have experience of biogas at this scale?

 

Thanks in advance for any help that you can give,

Samantha
