szénforrásokból

Szénforrásokból refers to a Hungarian term that translates to "from coal sources" or "from carbon sources." In a scientific and industrial context, it primarily pertains to the extraction and utilization of coal as a primary energy and raw material. Coal, a combustible black or brownish-black sedimentary rock, is formed from the accumulation and metamorphosis of plant matter over millions of years. Its composition is largely carbon, along with varying amounts of hydrogen, sulfur, oxygen, and nitrogen.

Historically, coal has been a cornerstone of industrialization, serving as a vital fuel for steam engines, electricity generation, and metallurgy. Beyond its energy applications, coal is also a source of various chemicals through processes like coal gasification and liquefaction, yielding products such as synthesis gas, methane, and liquid fuels. However, the combustion of coal is a significant contributor to greenhouse gas emissions, particularly carbon dioxide, and releases other pollutants like sulfur dioxide and nitrogen oxides, impacting air quality and climate change. Consequently, there is a growing global emphasis on transitioning away from coal-dependent energy systems and exploring cleaner alternatives or more sustainable methods for coal utilization. The term "szénforrásokból" therefore encompasses not only the extraction and use of coal but also the ongoing societal and environmental considerations surrounding this abundant but controversial resource.
