Coal turbines, commonly used in coal-fired power plants, generate electricity by burning coal to produce steam, which drives a steam turbine connected to a generator. Coal has historically been a dominant energy source due to its abundance and affordability. However, coal combustion releases significant greenhouse gases and pollutants, raising environmental concerns. Modern coal plants incorporate technologies like supercritical steam cycles and carbon capture and storage (CCS) to improve efficiency and reduce emissions. Despite a global shift toward renewable energy, coal turbines remain a key part of the energy mix in many countries.
- Government policies on carbon emissions and climate change affect coal turbine viability.
- Regulations on air pollution, such as sulfur dioxide (SO₂) and nitrogen oxides (NOx) limits, impact operations.
- Energy security concerns influence coal use in countries with large domestic reserves.
- Coal is often cheaper than other energy sources, but costs are rising due to environmental regulations.
- High capital investment for coal power plants, with long-term operational expenses.
- Declining profitability as many countries shift to renewable energy and impose carbon taxes.
- Job creation in mining, power generation, and maintenance, but potential losses due to industry decline.
- Provides stable and large-scale electricity generation, supporting industrial and residential demand.
- Health concerns due to air pollution and respiratory diseases linked to coal combustion.
- Public opposition to new coal plants due to environmental and climate concerns.
- Advances in supercritical and ultra-supercritical steam turbines improve efficiency.
- Carbon capture and storage (CCS) aims to reduce CO₂ emissions but remains costly.
- Co-firing coal with biomass or hydrogen can help lower environmental impact.
- Strict environmental laws regulate emissions and require pollution control technologies.
- Mining regulations affect coal extraction, transportation, and site restoration.
- International agreements, such as the Paris Agreement, push for a reduction in coal dependency.
- Coal combustion emits high levels of CO₂, SO₂, NOx, and particulate matter.
- Mining and waste disposal (e.g., coal ash) have significant land and water impacts.
- CCS and emission-reduction technologies help mitigate environmental damage but are not yet widely adopted.
