• Issues of corrosion and clogging in hydrogeology as an important factor in the design and operation of geothermal wells
  The use of natural thermal energy stored in underground geological formations has long been one of the alternative methods in reducing CO2 emissions. Obtaining so-called green energy with limited harmfulness to the already sufficiently destroyed human environment is becoming a challenge of the moment.
  The use of thermal energy accumulated in underground geological formations with a normal or abnormal temperature gradient is widely described in numerous publications [1], [2], [3], [4], [5], [7], [8], [9], [10], [12], [13], [16].
  Based on the number of boreholes drilled in past decades in Poland, a several of already implemented projects were created, mainly of a balneological and recreational nature, such as: Bukowina Tatrzańska, Białka Tatrzańska, Chochołów, Uniejów, Mszczonów, Kleszczów and others, as well as typical geothermal projects for obtaining heat for municipal purposes, such as: Geotermia - Stargard Szczeciński or the projects currently being implemented: Geotermia Toruń, Geotermia Koło, Geotermia Konin or Geotermia Gostynin and Pyrzyce [7], [8], [9], [10], [12], [13]... dalej
• Renewable energy auctions for the sale of electricity from renewable sources as support for biogas producers
  RES auctions are a financial support system for renewable energy producers (i.e. from biogas, biomass, wind, sun, etc.), introduced in Poland by the RES Act in 2015. Thanks to this system, the state guarantees the producer that it will buy energy from them at a guaranteed price for a specified number of years (usually 15 years) - even if the price of energy falls on the market. Biogas plants, thanks to the stability and predictability of energy production, are an important complement to dynamically developing but unstable renewable sources, such as photovoltaics and wind energy. In the context of striving for a low-emission economy, biogas plants are gaining importance as regulatory sources, capable of stabilizing energy networks by flexibly adjusting production to demand. Biogas plants, as a stable and predictable source of renewable energy, perfectly fit into the assumptions of the RES auction system, which will be continued in 2025 in accordance with the schedule presented by the President of the Energy Regulatory Office... dalej
