Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.

Electrons are held in their shells by an electrical force. The protons and electrons of an atom are attracted to each other. They both carry an electrical charge. Protons have a positive charge (+) and electrons have a negative charge (-). The positive charge of the protons is equal to the negative charge of the electrons.

South Africa, being the country most globally dependent on coal, derives up to 80% of its primary energy and electricity from the commodity, a trend largely unchanged over the past two decades. The nation produces more than 200 million tons per annum, with less than 70 million tons being exported in 2023, constituting less than 7% of global ...

The same challenges apply to coal-fired power plants as well. While geothermal heat is arguably more efficient than coal, it can be very expensive. Several coal-fired power plants have very high capital costs and are not cost-effective for commercial use. A geothermal power plant can cost up to a quarter of a billion dollars to build and maintain.

The image depicts the process of making electricity from coal, starting with a mine where coal is extracted, followed by a crusher that breaks the coal into smaller pieces, then transportation of coal to a gasifier. The gasifier converts coal into gas, which goes through a cooler before reaching the gas power plant.

Although the coal-fired power plant is being replaced by renewable energy power generation, it still accounts for over 35.1% of global power in 2020 (IEA., 2021). Therefore, capturing CO 2 from coal-fired power plants is a fast and practical approach to mitigate CO 2 emissions (Saptoro and Huo, 2013).
