This is biogas plant is specified to make 1,300 kWh per cow per year. 1,300 kWh x 60-cows = 78,000 kWh with 60-cows 78,000 kWh / 365 = 213.7 kWh per day 213.7 kWh per day / 24-hours = 8.9-kWh each hour This has a capacity factor of 90% to 100%. This means the biogas plant will produce energy between 90% to 100% of the time. Suppose the capacity factor was 20% This would mean that only 20% of the year it would be able to make 8.9-kWh each hour. Solar energy has approximately a 20% capacity factor since there is no sunlight at night. A photovoltaic solar array of 8.9-kWh has a cost of less than $10,000, and it would produce between 9,700 kWh to 17,800 kWh depending on where it is installed. This is between 12% to 23% of what a biogas will produce per year. The cost per installed watt for a photovoltaic solar array is less than $10,000 / 8,900 watts = $1.12 per watt and with a 20% capacity factor, the actual cost is $1.12 / 20% = $5.62 per watt This biogas plant has a cost of $100,000 / 8,900 = $11.24 per watt and with a 100% capacity factor $11.24 / 100% = $11.24 per watt This biogas plant has a cost of $100,000 / 8,900 = $11.24 per watt and with a 90% capacity factor $11.24 / 90% = $12.48 per watt As you may appreciate the biogas is fully priced per watt.
Do you have units in the United States of America? How scalable is your units? Are any of your units capable of handling a 1,500 mature head dairy farm?

If your farm was very big, could you solar by day and methane by night would eliminate the need for expensive storage

Does this work with stored slurry? That is, distribute supply through the year as cows are outside in summer.
Unfortunately not, the system needs fresh slurry otherwise the methane is lost
and pig slurry ?
Yes pig slurry can work
Until 💥 BOOM as in Texas .
How many kw per cow
Approx 0.15kw per hour per cow 🐄 so 200 cows = 30kw
What about cattle not kept in sheds?
@@michaelmulligan0 calculations need to be taken on available slurry
0.15kw per cow per hour
@lanforce energy zimbabwe
manure has no value in the food chain? really? sounds like a big fat lie to me
If directly aged for one year it becomes fertilizer this speeds up the process
