Bioenergy is one of several different options that can help us satisfy our energy needs. It’s a type of renewable energy obtained from recently living organic elements called biomass, and it may be used to make transportation fuels, heat, electricity, and products.
How is electricity produced by bioenergy?
Biopower systems use procedures similar to those used with fossil fuels to transform renewable biomass fuels into heat and electricity. To generate biopower, there are three ways to liberate the energy trapped in biomass:
Burning:
Direct combustion produces the majority of the electricity generated by biomass. To make high-pressure steam, biomass is burned in a boiler. This steam causes a series of turbine blades to rotate by flowing over them. The turbine’s spin drives a generator, which generates energy.
Decomposition of bacteria (anaerobic digestion) :
Organic waste, such as animal dung or human sewage, is collected in digesters, which are oxygen-free tanks. Anaerobic bacteria degrade the material here, producing methane and other byproducts to create a sustainable natural gas that may subsequently be cleaned and utilized to generate energy.
Conversion to a liquid or gaseous fuel :
Through gasification and pyrolysis, biomass can be transformed into a gaseous or liquid fuel. Gasification is a process that involves heating solid biomass at high temperatures with very little oxygen present in order to produce synthesis gas (or syngas), which is mostly made up of carbon monoxide and hydrogen. The gas can then be used to generate power in a normal boiler. It can also be used in a combined-cycle gas turbine to substitute natural gas.
Is bioenergy renewable or nonrenewable?
Biomass is an attractive fossil-fuel alternative because it is a renewable resource that is more evenly distributed over the Earth’s surface than finite fossil-fuel energy sources such as coal, oil, and natural gas, and maybe developed using more environmentally friendly technologies.
What are the advantages of bioenergy?
1 – Net greenhouse gas emissions are little or non-existent
2 – Is a useful method of disposing of garbage that would otherwise be debris
3 – Has well-proven technology for delivering consistent energy; can be stored with low energy loss
4 – It can help to stabilize soils, improve soil fertility, and prevent erosion where there are agricultural crops and forestry.
5 – In a cogeneration power plant, it can generate both heat and electricity.
What are the disadvantages of bioenergy?
1 – When compared to fossil fuels, is often more expensive because it takes more fuel to create the same amount of energy.
2 – Uses a lot of wood from natural forests, which can lead to deforestation, and if the wood isn’t completely burned, it can emit soot-like particles that can pollute the air.
3 – Some people argue that the land and water resources needed for biomass crops might be better employed for food production.
4 – When you include the expense of harvesting, extracting, transporting, and processing biomass, it may be quite costly.
