Renewable Energy In Nigeria. How to create yours for cooking and electricity by Dexpro: 12:06pm On Dec 20, 2015
With due respect to the moderator of this section, i hope this is the right section to post this very useful material. Over the past three years, research has been ongoing on how to harness the power of BIOGAS. In the present scenario of dwindling petroleum resources and global warming, exploring other avenues for eco-friendly fuels became essential. Biogas which is a clean and environmental friendly fuel emerged as one of the potential alternative fuels.

In view of this, i have decided to take any person who might be interested in generating his/her (Cooking/Electricity) energy @ home by the hand on how to construct a 500L BIOGAS TANK for domestic consumption ONLY.

This lesson is made possible by my teacher in BIOGAS TECHNOLOGY, MR J. Antoni Raj. (Rtd) Civil Engineer, Uthamapalayam and Dr. S Ajmal Khan, M.sc, P.hd, Professor- Emeritus, Centre of Advanced Study in Marine Biology, Annamalai University, Parangipettai, India.

All lectures will be supported with pictures. I need 10 nairalanders to indicate interest before i proceed. PLS DON'T DROP YOUR EMAILS.

Bubu isn't interested in this. He just allocated some money for oil exploration in NE instead of looking for alternative source of energy.

Sir i don't believe in impossibilities. As a matter of fact, those things possible today were actually impossible yesterday. Mobile phones/GSM was impossible in Nigeria like 40 years ago, but today it is possible.

Biogas Plant Using Kitchen and Food Waste

DAY 1: What is Biogas, What is Biogas Plant and How it Functions...?

What is Biogas...?

For those who are not familiar with the term Biogas :

Microorganisms who thrive in the absence of air digests the organic material and releases a mixture of gases. The gases thus produced contains mostly methane along with other gases like Carbon dioxide, Nitrogen and Hydrogen Sulphide in small quantities. This process is known as anaerobic digestion.

Methane is a colorless and odorless gas and is highly flammable. (It is Hydrogen Sulphide that smells bad) Methane is not poisonous.

Methane along with other gases occurs naturally in swamps, waste dumps and even in home toilets in the septic tank. Due to its highly flammable quality, it can be used as fuel. But capturing the methane from the atmosphere is very difficult as it is lighter than air. The Biogas Digester or Biogas Plant we see here is a device which helps us in collecting this gas and use it as fuel.

Biogas Plant

You can see the opened-up prototype of a Biogas plant in above photograph.

The Biogas plant consists of a digester tank, where the organic material is stored and the microorganisms work on them and release gas.
The gas thus produced is collected in a tank known as gas collector. In a floating type model, this tank is floating in the slurry and moves up-and-down based on the amount of gas stored in it
A guide pipe helps the gas collector tank to move up-and-down inside the digester tank.
Waste is fed through feed pipe inside the digester tank.
The fully digested slurry drains out through the outlet pipe. This can be collected, diluted and used as fertilizer for plants.
A gas pipe line from the Gas collector tank helps in utilizing the gas for cooking and lighting.

Now let's get down to business and construct a medium sized Biogas plant for home use
Re: Renewable Energy In Nigeria. How to create yours for cooking and electricity by Dexpro: 8:57pm On Dec 20, 2015
Selection of Tanks

This is my attempt at constructing a medium sized Biogas plant for home use as well for demonstration to students and others using a 750 liter capacity tank as digester and a 500 liter capacity tank as a gas holder, a floating type gas holder method. I have provided easy to understand step-by-step instructions on how to build the plant. Please go through this and feel free to post your comments and queries with respect to biogas.

Before selection of tanks, I need to consider how much of digestible kitchen and garden waste I could collect everyday for feeding the tank. In my case I can easily collect between 3.5 to 4 kilogram of waste from kitchen and home garden. This quantity will be sufficient for a biogas plant with 700 to 800 liter capacity digester tank. A simple thumb rule for biogas plant for home use is 5 kilograms of waste needs a 1000 liter capacity digester.

Now for the selection of gas holder tank, I need to consider the following before buying the tank:

The model I am building is with a floating type gas holder tank. That means the gas holder will move up and down based on the amount of gas inside. So, the gas holder tank should fit inside the digester and also should have minimum difference between their width as this will reduce in loss of gas through the sides.

During market search, I found that the 500 liters capacity tank will meet the requirement, having a width difference of about 100 mm, that means 50 mm on each side. So, I have decided to use the 500 liter tank as gas holder, which will have an up-and- down movement inside the digester using guides.

Some designs cater for a water seal between the digester and gas holder, but in my case that will considerably reduce the capacity of the digester. However, the gas loss through the sides will be very marginal with respect to providing a water seal and reducing the capacity of the digester.

In the above photographs, you can see the selection of my tanks. They are of very good quality three layered tanks that can withstand exposure to sunlight and acidic condition of the slurry inside.

Good idea. We need more of these. The FG under last admin tried something like this when the awarded contracts for production of eco-friendly cooking stoves for about N10B. It met with opposition from Nigerians who didn't understand the idea behind it fully. It was strangely reported as "cooking stove being discussed in FEC meeting".
Though we have natural gas, ideas like these will surely help get Nigerians thinking in the direction of self-sufficiency. Keep it up.

DAY 2: Tools Required

You can see here that construction of this plant does not require many tools. These are list of tools I have used:

A hacksaw with frame

A single sided hacksaw blade

A sharp knife

A medium sized hammer

Set of spanners to tighten the gas pipe connectors

For crimping the connectors with the ends of gas pipes, I got assistance from the shop from where I bought the gas pipes. They helped me with their Hand crimping equipment as per my requirement.
