As we have been discussing many BIOFUELS/Alternative Energies/Green Energies, but we are neglecting the vital importance of BIOGAS with value to Industry as well as on domestic spheres. Bio Gas is not considered a today’s phenomenon, but has been utilized across the world for many centuries, particularly in the Indian Sub-Continent, where it is known as Gobar Gas in the rural regions. In today’s article, I am not putting spot light on its Domestic Importance but on its Industrial Implications, as Pakistan is suffering from worst Energy Crisis, as many Industries, who have Gas Fired Generators are not availing Natural Gas in the winter, ultimately enduring huge loss for Country’s GDP and hurdle in achieving Export Targets.
Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Biogas is produced by anaerobic digestion or fermentation of biodegradable materials such as biomass, manures, sewage, municipal waste, green waste, and plant material and energy crops. This type of biogas comprises primarily methane and carbon dioxide. Biogas can be used as a low-cost fuel in any country for any heating purpose, such as cooking. It can also be used in modern waste management facilities where it can be used to run any type of heat engine, to generate either mechanical or electrical power. Biogas can be compressed, much like natural gas, and used to power motor vehicles. But in Pakistan, It can also be used to operate Gas Fired Industrial Generators (10KW-4MW) as well. According to statistics, there is little difference between composition of Biogas and Natural Gas; therefore, Biogas can be used in typical Gas Fired Generators.
Rationale of the Project
Germany is the largest producer of BIOGAS Plants and their Energy Production comprises on BIOGAS is more than 4,000 MWs. Besides, India and China are also exploring their horizons in this renewable energy and forming joint venture with German Companies to manufacture BIOGAS Plants in their home countries to explore the untapped potential. Within Pakistan’s Perspectives, Pakistan has one of the largest numbers of Milking/Meat Animals and Chicken. Thus, it has abundant Cow/Buffalo/Chicken’s Dung to be used for producing BIOGAS to operate typical Gas Fired Generators. In this regard, I researched, and one of the leading biogas plants manufacturers claimed that we (Pakistani Industrialists/Farm Owners) can generate 1 MW of electricity on GE JENBACHER Gas Fired Generator by utilizing biogas on their BIOGAS Plants.
For 1 MW Generation, about 150 Tons Manure/Day; Cow/Buffalo with 70% and Chicken’s Dung with 30% is required to operate 1 MW Gas fired Engine. Around 2000 Cows are required to produce 150 Ton Manure (i.e.; 75KG/COW/Day). Special Enzymes/Catalyst can be used to enhance the plant production/pressure by 20%. That kind of Biogas Plants cannot merely produce BIOGAS but also produce Soil Conditioner/Bio-Fertilizer as their by-products, which can be sold to many farmers.
Last but not the least; I do opine that Pakistan has enormous potential in this regard, so Govt. and Entrepreneurs should come up with new innovative ideas to produce Biogas for Electricity as well as to produce Biogas Plants utilize here as export it at large. Indigenous Industrialists in any field can exploit this fabulous technology by installing Biogas Plant in their premises and availing Feedstock; Manure from nearby areas to operate their usual Gas Fired Engines
that may lead to achieve more production and export targets. This project is feasible, because feedstock is easily available at very cheap prices, and its by-product; Bio-Fertilizer can also be sold at good price. Just one time cost is required to install biogas plant, and it can be operated with few personnel. Therefore, Local Business People can earn and save a lot from local untapped resource.
