The chemical energy stored in coal is released through various processes as the fuel is burned. Coal, a commonly used source of fossil fuels, has been widely studied for its ability to be burned without damaging the environment or causing harm to wildlife.

In many ways, coal stores the chemical energy it contains in two distinct types: in coal ash and in oil. Coal ash is made up of small particles of volcanic ashes that have settled on the surface of the coal mine and are no longer present in the surrounding area. It is less than 1% of all the coal produced worldwide and it plays a crucial role in helping to prevent mineralization and reducing greenhouse gas emissions.
On the other hand, oil is a significant contributor to the release of chemical energy from coal during combustion. This can happen through various mechanisms, such as the flaring of flammable gases (such as methane) or the emission of pollutants into the air. Some estimates suggest that over 85% of all industrial burning in the United States involves the use of oil as an energy source. The release of these chemicals into the atmosphere has significant environmental impacts, including climate change and habitat loss.
One potential mechanism by which chemical energy is released from coal is through the process of combustion itself. When coal is burned, it releases heat, which is converted into light energy. This light energy is then used to power engines and other electrical equipment. As the amount of chemical energy stored in coal increases, this process becomes more efficient and cost-effective.
Another mechanism by which chemical energy is released from coal is through the process of pyrolysis. Pyrolysis involves breaking down into simpler compounds through reactions. This process can also release chemical energy, particularly if there is a high proportion of pyromethane gas, which is a key component of many industrial processes.
In addition to these processes, chemical energy is also released through the process of purification. Coal mines often produce large amounts of dust, so they may contain pollutants such as sulfur dioxide, nitrogen oxides, and cadmium. These pollutants can contribute to respiratory problems and other health issues when inhaled. By washing the coal or using an air filtration system, some companies can reduce their exposure to these pollutants and improve the quality of their air.

Overall, while coal remains a significant source of energy, its use has both positive and negative effects on the environment and human health. By better understanding the sources and mechanisms of chemical energy storage in coal, we can develop more sustainable practices and minimize our impact on the planet.
