Biolectric Farm Scale slurry only Anaerobic Digesters(English)

Biolectric are farm scale Anaerobic Mono Digesters that create electricity and hot water from dairy slurry. These award winning systems allow dairy farmers to turn their waste dairy slurry into valuable renewable energy.
The systems work by simply recreating the environment of a cows stomach and further digesting dairy slurry to release environmentally damaging methane which is then filtered and turned into biogas.
Renewable biogas will then be used as fuel in a specially designed engine to create Electricity and heat for the farm. The slurry is then turned to digestate which because of the way it is broken down becomes a very valuable fertilizer, further adding to the economical and sustainable benefits of a biolectric plant.

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.

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

Until 💥 BOOM as in Texas .

manure has no value in the food chain? really? sounds like a big fat lie to me

[@PreservingHumanity]

If directly aged for one year it becomes fertilizer this speeds up the process

[@douglasbaskett2298]

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?

Does this work with stored slurry? That is, distribute supply through the year as cows are outside in summer.

[@yorkshiresingletrack4317]

Unfortunately not, the system needs fresh slurry otherwise the methane is lost

[@WhatTheRiton]

and pig slurry ?

[@biolectric5878]

Yes pig slurry can work

How many kw per cow

[@yorkshiresingletrack4317]

Approx 0.15kw per hour per cow 🐄 so 200 cows = 30kw

[@michaelmulligan0]

What about cattle not kept in sheds?

[@yorkshiresingletrack4317]

@@michaelmulligan0 calculations need to be taken on available slurry

[@biolectric5878]

0.15kw per cow per hour
