Energy and emission balance of the Małopolskie Voivodeship in 2020

The article presents the energy balance for the Małopolskie Voivodeship in 2020. It shows the production, import, input and output of transformation, own consumption of power plants, combined heat and power plants, network losses and consumption in the economic sectors (industry, waste), transport (road and rail), buildings (residential and tertiary), as well as in agriculture and forestry of the following energy carriers: hard coal, crude oil and petroleum products (including gasoline, diesel, LPG), non-renewable
waste, derived heat and electricity. An estimate of greenhouse gas emissions in 1990 and 2020 in the Małopolskie Voivodeship is also presented.

Key words: greenhouse gas emissions, energy scenarios, energy balance

Assessment of the potential for CO2 capture using post-combustion methods

The combustion of fossil fuels in the process of generating electricity causes the emission of carbon dioxide, which is considered the main anthropogenic reason for global warming. The paper’s subject is to assess the potential for CO2 capture using post-combustion methods. Post-combustion methods such as chemical absorption, physical separation, membrane separation, and chemical looping, are described. The thermodynamic modeling of a coal-fired supercritical power plant integrated with a post-combustion carbon capture installation using the solvent method is performed. The results obtained from the model are used to investigate the impact of the power plant when carbon capture is performed.

Key words: CO2 emissions, PCCS, amine technologies

Technological aspects of mining chain production development

This paper presents a brief historical overview of the development and types of mining chains currently in production, as well as their contribution to the global market. The directions of development for mining link chains were identified in terms of the materials and strength parameters applied. The negative influence of certain factors that decrease the performance of mining chains are also demonstrated.

Key words: chain, safety, durability

The Kalman autonomous planetary rover

The project presented in the article is proof of the usefulness of student organizations and its effectiveness in the popularization of advanced technologies as well as future solutions in industry. A student-developed planetary rover, using a Kalman filter and other algorithms responsible for dynamic terrain mapping and pathfinding, is capable of non-collision movement in the most challenging environments. Moreover, the rover uses a 6DOF arm developed by students to undertake manual actions, such as soil sampling or maintenance tasks with ease. The invention is provided with a drill to be capable of extracting a sample from a depth of 30 cm, which is expected to greatly enhance the research of the geological history of the surveyed region. The robot has been tested numerous times at planetary rover competitions with success, proving the potential of such platforms as one of starting points in space exploration and opportunities in industrial use, especially in hard-to-reach mining areas. The featured project represents an inspiration for future young engineers and scientists by opening perspectives for implementing similar technologies for more efficient and safer operations in industry.

Key words: rover, robot, autonomy, mechanization, mining
