The article is a case study of the development of cavernous weathering forms (alveoli and tafoni) on a sea cliff near Keflavik on the Reykjanes peninsula in southwestern Iceland. The majority of forms are found on vertical or inclined rock faces and cluster around the uppermost edge of the cliff. Single hollows gradually evolve due to back wearing of their sidewalls into complex caverns, until finally the whole outermost layer of basalt is removed. Particular attention is paid to mineralogical changes of basalts due to chemical and salt weathering. Chemical decomposition of feldspars, pyroxenes and olivines followed by precipitation of iron on and within the weathering rind, the presence of micro- and macro-pores such as gas bubbles and delivery of marine salts are proposed to be the key factors influencing cavern development.

Hydrogen it one of most spread radical on earth, this gas has to become alternative due to so general occurrence for mineral fuels exactly chance. Low is unchallenged advantage of employment of hydrogen in car engines emission, then hydrogen is fuel ecological completely. On way to general employment of hydrogen biggest barrier stagnant as storage of this gas is fuel and high cost of its production.

In this paper we are investigating the question of technical and economic efficiency of coal-hybrid power plants construction. We are considering a combined-cycle gas turbine plant, in which combustion heat of the coal is used to provide the necessary initial temperature in the gas cycle and before the steam turbine while the hydrogen fuel is used for intermediate steam superheating. This technical solution allows to increase significantly power and heat generation efficiency but also raises the issue of the most effective way of producing hydrogen. As the research results revealed, there are large scale production and row material bases available in Russia, therefore the question deserves further investigations.

The article aims to analyse the potential role that hydrogen could play in the post-pandemic recovery of Portugal and its climate policy. The article focuses on reducing greenhouse gas emissions and creating new workplaces. The basis for analysis is the Portuguese hydrogen strategy, published in May 2020 and other strategic documents. In the first part of the article, climate goals adopted by the European Union and Portugal are described and analysed. Then the hydrogen strategy of Portugal was analysed from the perspective of hydrogen contribution to the emission reduction by 2030. The article describes the role of hydrogen in the Portuguese economy, paying particular attention to the 2020–2030 horizon, but also covers a period till 2040. The second part analyses the impact of COVID-19 on the Portuguese economy. Based on the International Energy Agency’s estimates, the potential for creating new workplaces is described.

Artykuł podejmuje najważniejsze kwestie dotyczące produkcji wodoru w celu wykorzystania go w przemyśle oraz dziedzinach życia związanych z konsumpcją indywidualną. Autorzy starają się przybliżyć perspektywy rozwoju rynku wodoru w Federacji Rosyjskiej, nie unikając jednak odpowiedzi na pytania dotyczące rozwoju rynku wodoru w ujęciu szerszym: regionalnym oraz globalnym. Zastanawiają się nad możliwościami, które niesie ze sobą wykorzystanie wodoru w procesach produkcyjnych i sferze transportu – obecnie, jak również w przyszłości. Istotne miejsce na rynku wodoru będą ich zdaniem zajmować Rosjanie, którzy dominują w globalnym sektorze energetycznym nie tyko w sferze produkcji gazu ziemnego czy ropy naftowej, ale także w innych segmentach tego sektora.

The article deals with the most important issues linked to hydrogen production, its industrial and individual consumption. Authors focus on hydrogen market development perspectives with reference to broader, regional, and global contexts. They also analyse advantages of hydrogen use in the production processes, transport sector – currently and in the future. The Russian Federation shall occupy prominent place on the hydrogen market since this country is dominant in the global energy sector, not only in terms of natural gas and petrol production, but also in its other segments.

For years, European Union policy has been geared towards promoting energy sources that do not degrade the environment. Hydrogen could be such an energy source. The aim of this article is to familiarize readers with the methods of generating hydrogen from biomass and certain waste, and to determine its colour. In the European Union, different ‘colours’ are assigned to this element – green, pink, yellow, blue, turquoise, white, grey, brown and black. The colour depends on the source and method of extraction. Hydrogen, as an environmentally friendly energy source, should have green, pink or blue colour.

Polityka Unii Europejskiej od lat nastawiona jest na promowanie źródeł energii, które nie degradują środowiska. Takim źródłem energii może być wodór. Celem artykułu jest przybliżenie czytelnikom metod pozyskiwania wodoru z biomasy i niektórych odpadów oraz określenie jego koloru. W Unii Europejskiej przypisuje się temu pierwiastkowi różne kolory – zielony, różowy, żółty, niebieski, turkusowy, biały, szary, brązowy i czarny. Kolor zależy od źródła i metody pozyskania. Wodór, jako źródło energii uznawanej za przyjazną środowisku, powinien mieć kolor zielony, różowy lub niebieski.

The article addresses the issue of the implementation and development of hydrogen fuel in Poland in the near future. The first part offers a detailed description of the types of hydrogen fuel by acquisition technology, information on barriers to the introduction of this technology into the market, and an answer to why hydrogen cars are still not widely used. The second part of the article is devoted to the analysis of barriers to the introduction of hydrogen fuel in Poland. This part presents the problems of the slowly developing Polish hydrogen infrastructure and the lack of regulations governing this type of fuel. This article is a review and its purpose is to present the barriers and evaluate the introduction of hydrogen as an automotive fuel with a special focus on Poland.

Artykuł podejmuje problematykę wdrożenia i rozwoju paliwa wodorowego w Polsce w najbliższej przyszłości. W pierwszej części można znaleźć szczegółowy opis rodzajów paliwa wodorowego według technologii pozyskiwania, informacje o barierach w wprowadzeniu tej technologii na rynek oraz odpowiedź, dlaczego samochody napędzane wodorem wciąż nie są powszechnie stosowane. Druga część artykułu została poświęcona analizie barier wprowadzania paliwa wodorowego w Polsce. W tej części została przedstawiona problematyka wolno rozwijającej się polskiej infrastruktury wodorowej oraz brak przepisów regulujących ten rodzaj paliwa. Niniejszy artykuł ma charakter przeglądowy i jego celem jest ukazanie barier oraz ocena wprowadzania wodoru jako paliwa samochodowego ze szczególnym uwzględnieniem Polski.

First Polish books on the subject of electricity were published in the 70s of the 18th century. Among them were a guidebook on the installation of lightning conductors by Józef Osiński in 1784 and a physics textbook of 1777, whose extended edition was issued in 1801 (volume 1) and in 1803 (volume 2). Moreover, in the times of the reign of Stanislaus II, Polish physics textbooks appeared: by Samuel Chrościkowski (1764), Józef Rogaliński (4 volumes in the years 1765–1776), Józef Lisikiewicz (two volumes in the years 1779 and 1781), and by Jan Michał Hube (1783 and 1792). In his work the author analyses the state of knowledge at that time concerning the nature of electricity, static electricity, magnetism, lightning discharge, earth charge, conductors and insulators, influence of electricity on living organisms, aurora borealis, as well as evolution of this knowledge at the turn of the 18th and 19th centuries and its evaluation from today’s perspective.
