COAL

GENERAL

The energy crisis is continuing and has become a threat to regions and countries with a thriving industrial sector such as Europe and China. In particular, in these countries, coal is the main source of energy production for both economic and living activities. However, now, when the demand for energy is increasing after the pandemic, coal has also become a scarce commodity because supply is not enough to meet demand.

So, what kind of fuel can replace coal? And will it be as effective as coal? Let’s see a comparison table between fossil fuel (represented by coal), and a green fuel – Biomass (biomass).

BIOMASS HAY THAN ĐÁ MỚI LÀ NHIÊN LIỆU ĐỐT HIỆU QUẢ?

COAL VS BIOMASS

 

COAL

BIOMASS

Definition

a fossil fuel formed from dead organisms containing CO2, buried in the ground, decomposed and transformed into coal, oil, natural gas, ..

Biological materials including plants, industrial crops, agricultural and forestry by-products, etc., which can be used to burn to create an abundant source of energy.

Calorific value (kcal/kg)

 7,800 – 8,000

 

3,200 – 4,500

 

Formation / Mining Time

Millions of years

Several years (depending on the season, planting time, etc.)

In the industrial boiler industry

  • a common burning fuel; Widely used in the field of power generation
  • Delivers high energy efficiency and is a reliable fuel for energy production
  • Mainly used as fuel for specialized boilers to ensure that the fuel is exhausted, and to limit harmful emissions to the environment such as: Carbon, Methane, etc.

Advantage

  • Low price
  • Available and easy to find
  • Easy to transport
  • Can be regenerated by planting forests
  • Balance, reduce CO2 . emissions
  • Take advantage of a variety of waste sources: industry – agriculture – forestry
  • Environmentally friendly

Disadvatges

  • Limited (non-renewable) energy source
  • Causing large emissions (both exploitation and use emit a lot of CO2 into the environment)
  • Took a long time to form
    Adverse effects on the environment and human health.
  • Influenced by seasonality and distribution range
  • Energy efficiency is not high
  • Takes up storage space

CONCLUSION

Biomass can replace coal?

  • Through the above comparison table, although Biomass has some limitations, with effective solutions, modern technology and advanced techniques, Zero Waste can ensure the efficiency brought from this green fuel. At the same time, Zero Waste affirms that this is a potential energy source for a sustainable future.
  • Biomass is absolutely the right choice to replace coal (the fuel source is gradually depleting) with its sustainable and renewable nature and is completely an environmentally friendly energy source.
