Economic use of methane Project

Project is planned for 4 years (2018-2022) and concerns the mines “Budryk” and “Knurów-Szczygłowice”.

Hard coal mining is inherently associated with obtaining methane by-product. Using and management of methane in Poland is associated with obtaining significant economic benefits, increasing safety in mines and it is part of the implementation of the national strategy assuming further development of the circular economy which means by-products of one process are used in another process.

In 2018 JSW’s methane collected by methane drainage systems was used for the production of electricity, heat or cooling in 57% which means that there is a huge potential for improvement in this area.

The main goal of this project is to produce electricity using gas from methane drainage systems. JSW S.A. is going to achieve this by creating new infrastructure and implementing modern technologies.

The project concerns the management of methane from the KWK Budryk and KWK Knurów-Szczygłowice mines and the production of energy for the use of these mines, and then other mines owned by JSW. In the Project concept, it does not include the sale of electricity outside JSW.

Mining activity is one of the most energy-consuming industry, which is associated with significant mechanization of the production process carried out continuously with a three-shift system. This means that JSW has a significant demand for electricity at the level of approximately 1 TWh during the year.

Due to JSW's access to significant and stable methane surpluses, it is possible to reduce the costs of purchasing electricity, and to manage methane instead of releasing it into the atmosphere, which would entail additional emission costs.

Economy

Total power of cogeneration systems installed at JSW S.A. will be 43,9  MWel in 2022. Production potential of “Green Energy” in “Budryk” mine and “Knurów-Szczygłowice” mine in 2022 will amount approx. 330 000 MWh per year. The amount of produced energy covers approx. 33% of JSW’s annual electricity demand. The amount of produced energy would supply 180 thousand. medium-sized households in Poland.


Ecology

The annual amount of "Green Electricity" produced 330 thousand MWh at JSW S.A. allows you to save 165 thousand Mg of thermal coal needed to be consumed in a conventional coal-fired power plant to produce the same amount of electricity. The implementation of "Green Investments" in “Budryk” and "Knurów-Szczygłowice" mines by 2022 - will allow the reduction of methane emissions into the atmosphere by a total of 80 million m3 of CH4, which gives about 1,6 million Mg CO2e per year.
