What is Biomass Energy – The Pros and Cons

Benefits of biomass energy

Most of you probably hear the term biomass energy thrown around a lot, but you’re not sure what it is.

Biomass energy is simply renewable energy from organic matter – like plants or waste products.

In general, biomass can also include everything from wood and crop waste to sewage and landfill gas.

When burned, biomass releases energy which is in the form of heat and can be used to generate electricity or power vehicles.

Because it comes from renewable sources, biomass is considered to be a sustainable option for meeting our energy needs.

Additionally, biomass combustion produces significantly less carbon dioxide than burning fossil fuels, making it a cleaner option as well.

As we continue to look for ways to reduce our reliance on fossil fuels, biomass energy will likely play an important role in our future.

With that said, there are pros and cons to using biomass energy, and today I’m going to talk about both of them. So, sit back, relax and stay tuned if you are excited to know more…

How Does Biomass Energy Work

The working of biomass energy is actually quite simple to understand. It’s basically a step-by-step process that happens as follows:

1- In the case of plants, energy from the sun is carried and stored in the form of chemical energy.

2- When cut or killed, plant matter, such as wood chips, straw, and other materials, is then supplied to the biogas energy plant.

3- Organic matter and even animal manure are then burned into energy plants to release energy in the form of heat or steam.

4- Turbines are today also powered by steam energy like this, which is sent via pipes to them. The steam rises and drives turbines, which ultimately produce electricity or heat for residences, industries, and businesses.

In most developing and developed countries like the US, biomass power plants have been cited in countryside areas throughout the country to provide electricity to the local people.

If you are using a fireplace in your home, you already have some experience in using biomass for heating.

Advantages of Biomass Energy

Wood, for many years, has been recognized as a heating fuel in ovens, fires, and other conventional heating methods. Biomass fuel, on the other hand, has rapidly outpaced fossil fuels in terms of development.

Today, biomass fuels are considered to be an innovative source of power due to the following advantages:

1- It’s a Renewable Source of Energy

The biggest advantage of biomass energy is that it is a renewable energy source.

Renewable energy sources are essential as they can be replenished after use. As many biomass fuels such as wood and plant life may be regrown, it’s genuinely a renewable source because of its ability to renew.

This also means that we will never run out of biomass as long as there is sunlight and organic materials such as crop waste, sewage sludge, garbage, and manure.

It’s interesting to note that lumber is plentiful in supply in countries like the US and Russia, making it the most crucial biomass energy source.

Whereas in a country like the United Kingdom, chicken droppings are the primary source of biomass fuel.

2- It’s Versatile

This simply means that biomass energy can be used in several ways to create power.

Depending on the type of biomass, it can be burned directly or used to create biogas, which can then be used for the generation of electricity or heat.

For example, oil from many sources, such as corn and palm trees, is refined into ethanol, which is then used as biodiesel to fuel most vehicles, including powerful jet engines. It’s also used to make certain alcoholic beverages like spirits.

There is definitely no end to the number of ways biomass can be acquired and utilized on Earth, with an incredible variety of living creatures.

3- It’s a Cleaner Energy Source with Emissions That are not Harmful

Another significant advantage of biomass energy is that it is much more environmentally friendly than other forms of energy.

For example, biomass produces significantly less carbon dioxide when burned than fossil fuels.

This is because the carbon dioxide that is released when biomass is burned is absorbed from the atmosphere by the plants used as biomass.

This means that the overall effect of biomass combustion on atmospheric carbon dioxide levels is nil.

On the other hand, when you burn fossil fuels, the carbon dioxide that is released will be trapped in the ground for millions of years.

This release of ancient carbon dioxide into the atmosphere contributes significantly to the greenhouse effect and global warming.

4- It’s also Cheaper Compared to Fossil Fuels

The cost of producing biomass energy is also cheaper than the production of fossil fuels.

This is due to the fact that the raw materials used to produce biomass are readily available and easy to find.

There is also no need for special kinds of equipment or technology to extract the materials.

This makes the entire process of producing biomass energy much cheaper than other forms of energy.

5- Reduced Dependency on Fossil Fuels

Biomass energy is a kind of energy that largely reduces our dependence on fossil fuels, which are non-renewable energy sources.

This is because it provides an alternative energy source that can be used to generate power without the use of fossil fuels.

This is significant for our planet and the people living on it because it helps to reduce our reliance on fossil fuels that are slowly being depleted.

6- Helps in Reducing the Waste that Goes to the Landfill

What I mean by this is – many biomass materials, such as agricultural and forestry wastes, can be used as fuel.

This ultimately helps reduce the waste sent to landfills, where it emits methane gas, a greenhouse gas – that is much more harmful than CO2.

7- It Creates Jobs and Boosts the Economy

Lastly, I think biomass energy production is a boon to society as it also creates jobs and boosts the economy.

This is because the process of producing biomass energy requires the use of labor and robust manpower, which creates job opportunities for people.

In addition, the money spent on buying biomass materials and products also helps to boost the economy.

Disadvantages of Biomass Energy

Biomass energy definitely has a lot of advantages, but there are also some disadvantages that need to be considered as well.

These include:

1- Limited or Inconsistent Supply

Although there is a lot of biomass material available on Earth, it is still a limited resource.

While this may sound to be counterintuitive at first, from what I said before, it’s quite logical.

Why you may ask?

Because the majority of the world’s population still relies on wood as their primary source of fuel.

And as the demand for energy increases, the supply of wood and other biomass will decrease, which will eventually lead to price hikes.

The supply of biomass materials can also be quite inconsistent depending on the location.

For example, the amount of wood available in a particular area depends on the number of trees that are cut down.

And since the growth of trees takes years, there will be times when the supply is low and times when it’s high.

2- It’s not Completely Clean When Burned

While biomass energy is a renewable and relatively clean source of energy, it’s not completely clean.

When biomass is burned, it emits CO2 and other harmful pollutants into the atmosphere.

These pollutants can cause respiratory problems, heart disease, cancer, and other health problems.

3- Not very Efficient Compared to Fossil Fuels

The efficiency of biomass energy is also quite low compared to other sources of energy such as fossil fuels.

Because biomass needs to be burned in order to produce the same amount of energy as fossil fuels, this can lead to more pollution and environmental damage.

Furthermore, biomass energy production also needs water in order to grow the crops and trees that will be used as fuel.

This means that it can put a strain on water resources, which is already a problem in many parts of the world.

Why should we continue to use water as it is? Water can be used in countless ways, and because alternative energy sources like wind turbines already do so, there’s no reason why the water couldn’t.

4- Can Lead to Deforestation

As I’ve mentioned before, most of the world’s population still relies on wood as their primary fuel source.

This reliance can lead to deforestation, as people may clear forests to make room for more farmland to grow crops for biofuel.

Deforestation can cause a number of problems, such as soil erosion, loss of biodiversity, and climate change.

5- Takes up a Lot of Space

Another significant downside of producing and using biomass energy is that it takes up a lot of space.

The crops that are grown for biofuel, as well as the storage facilities for the biomass, require a lot of land, machinery as well as industries.

This can be a problem in areas where land is already scarce.

6- Higher Costs in Comparison to Other Alternatives

Biomass fuels are generally less expensive to produce than other fossil fuels, but they often exceed the costs of many other types of renewable energy sources such as solar, water, and wind.

In certain circumstances, biomass projects are considered to be unprofitable and not to be worth the price.

Particularly in terms of irrigation, when water is scarce, the extra cost may make it a non-viable option.

Above all, the cost of machinery utilized in extraction is also a consideration since it includes the transportation of biomass.
