• Poszukiwania naturalnego wodoru – ewenement geologiczny czy potencjał poszukiwawczy
  Natural hydrogen is a recently identified, clean, and low-carbon source of hydrogen generated by the Earth, capable of migrating and accumulating in geological formations. Its cost could be much lower compared to other hydrogen sources, like most common methane reforming or water electrolysis. It is not merely an energy carrier, but a resource in itself, and it does not require the depletion of one energy source to utilize another. It operates independently of human-made energy or particular raw materials. The exploration efforts and economic assessment of natural hydrogen resources is underway in some locations, such as France, Spain, and Australia, while in Mali, the exploitation of a natural hydrogen deposit in Bourakebougou has recently begun.
  This article presents the current state of knowledge regarding the processes of natural hydrogen generation and the conditions for its accumulations in rocks. The characteristics of the hydrogen system are presented, which serves as a reference to the oil system, a widely used approach in hydrocarbon exploration. Many studies indicate that the most effective hydrogen generation process is serpentinization, a low-temperature metamorphism of ultramafic rocks in the presence of water. Tectonic activity plays an extremely important role, as renewed deep faults can serve as pathways for hydrogen migration from deeper layers of the Earth... dalej
• Nanomaterials as prospective components of drilling fluids
  Drilling fluids are a key element of drilling technology, not only in the oil and gas industry, but also in geothermal energy (shallow and deep geothermal), trenchless technologies and many others. The article discusses the use of selected nanomaterials as prospective components of drilling fluids, especially those used under high pressure and temperature (HPHT) conditions. The current development of nanotechnology opens up new opportunities for the drilling fluid industry. Thanks to the use of nanomaterials, the properties of drilling fluids can have a direct impact on increasing drilling efficiency, stability of boreholes, minimizing the impact on the natural environment, but can also contribute to improving the safety of drilling operations... dalej
• Strategic purpose and opportunities for the use of biogas (biomethane) in Poland
  The article attempts to rationally use the energy values of biogas (biomethane), taking into account technical and economic aspects and limitations occurring in the Polish reality. Due to the fact that the structure of the Polish gas system differs significantly from Western European systems, the introduction of biomethane produced in biogas plants to the distribution network seems to be very limited. The most effective way to manage biogas is to use it at the place or near its production... dalej
