Biogas energy is a renewable and sustainable energy source that is produced by the decomposition of organic matter such as animal waste, food scraps, and sewage. This process produces a mixture of gases, primarily methane and carbon dioxide, which can be captured and used as a source of fuel for cooking, heating, and electricity generation. In Nigeria, biogas energy is gaining popularity as an alternative to Liquefied Petroleum Gas (LPG), also known as cooking gas. In this article, we will explore the costs of using biogas energy and how they compare to LPG in Nigeria.

1. The Initial investment costs.Research has made it abundantly clear the gap and low cost in investing and depending on Biogas plant. The initial investment costs for setting up a biogas system can vary depending on the size and complexity of the system. On average, a small-scale biogas digester system in Nigeria can cost between ₦200,000 to ₦400,000 ($500 to $1,000). This includes the cost of materials, labor, and installation. On the other hand, the initial investment for an LPG cooking gas system can range from ₦20,000 to ₦100,000 ($50 to $250), depending on the type and size of the gas cylinder and stove purchased.

2. The Fuel costs. It has been proven that, in terms of fuel costs, biogas is significantly cheaper than LPG. Biogas is produced from waste materials, which means there is no cost associated with the raw material. LPG, on the other hand, is a fossil fuel and has to be purchased at market prices. In Nigeria, the current cost of LPG as at the period of this research, is around ₦200 ($0.50) per kilogram, while biogas is essentially free once the system is set up.

3. The Maintenance costs. Biogas systems require regular maintenance to ensure efficient and continuous production of gas. This includes monitoring the temperature and pH balance of the digester, replacing worn-out parts, and cleaning the system. The cost of maintenance can vary depending on the size and complexity of the system, but it is generally lower than the maintenance costs for an LPG system. LPG systems require regular refilling of the gas cylinders and can also require maintenance and repairs if there are any issues with the stove or gas line. What a huge difference!!!

4. The Environmental costs. Recen discovery. One of the major advantages of biogas energy is its positive impact on the environment. Biogas reduces greenhouse gas emissions by capturing methane, a potent greenhouse gas, that would otherwise be released into the atmosphere. Experience has shown that it also reduces the need for deforestation and reduces waste pollution. LPG, on the other hand, is a fossil fuel and contributes to air pollution and climate change. 5. The Availability and accessibility. The disadvantage of LPG product in Urban development area. This product is readily available and accessible in urban areas of Nigeria, but it may be more difficult to find in rural areas. Biogas, on the other hand, can be produced locally and is not dependent on distribution networks. This makes it more accessible in rural areas where LPG may not be available.

SUMMARY:

Overall, with regard to the introduction of Biogas Energy and the fast growing awareness, cost of using biogas energy can be compared to nothing, will be considered significantly lower than LPG in Nigeria. While the initial investment for biogas installation may be higher, the fuel costs and maintenance costs are much lower, making it a more cost-effective option in the long run. Significantly, biogas has positive environmental benefits and can be produced locally, making it a more sustainable and accessible energy source for communities in Nigeria.  Join the CeeCeeObed awareness campaign!!!
