Biomass energy

People have used biomass energy— from living things—since the earliest “cave men” first made wood fires for cooking or keeping warm.
Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals. The most common biomass materials used for energy are plants such as corn and soy, wood, energy crops and waste. These are called biomass feedstocks.
The energy from these organisms can be transformed into usable energy through direct and indirect means. For example, biomass can be burned to create heat ( it‘s direct), converted into electricity ( also direct), or processed into biofuel (indirect).
There are 3 ways we can produce it.
First way is by burning.
Most electricity generated from biomass is produced by direct combustion. Biomass is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity.
Organic waste material, such as animal or human sewage, is collected in oxygen-free tanks called digesters. Here, the material is decomposed by anaerobic bacteria that produce byproducts to form a renewable natural gas, which can then be purified and used to generate electricity.
3rd one is by conversion to a gas or liquid fuel
Biomass can be converted to a gas and liquid fuel through gasification and pyrolysis. Gasification is a process that exposes solid biomass material to high temperatures with very little oxygen present, to produce synthetic gas. The gas can then be burned in a boiler to produce electricity. It can also be used to replace natural gas in a combined-cycle gas turbine. And pyrolysis uses a similar process to gasification but under different operating conditions by producing bio-oil.
Biomass and the environment
Biomass is an integral part of Earth’s carbon cycle. The carbon cycle is the process...
