a b s t r a c tThe threat posed by climate change and the striving for security of energy supply are issues high on the political agenda these days. Governments are putting strategic plans in motion to decrease primary energy use, take carbon out of fuels and facilitate modal shifts.Taking a prominent place in these strategic plans is hydrogen as a future energy carrier. A number of manufacturers are now leasing demonstration vehicles to consumers using hydrogen-fueled internal combustion engines (H 2 ICEs) as well as fuel cell vehicles. Developing countries in particular are pushing for H 2 ICEs (powering two-and three-wheelers as well as passenger cars and buses) to decrease local pollution at an affordable cost.This article offers a comprehensive overview of H 2 ICEs. Topics that are discussed include fundamentals of the combustion of hydrogen, details on the different mixture formation strategies and their emissions characteristics, measures to convert existing vehicles, dedicated hydrogen engine features, a state of the art on increasing power output and efficiency while controlling emissions and modeling.

“…The presence of hydrogen in metals is an essential technical and scientific problem, since hydrogen, penetrating in structural materials, initiates the formation of various types of defects and significantly affects physical and mechanical properties of metals and alloys [1][2][3][4][5][6]. Hydrogen embrittlement leads to accelerated depletion of the constructional element resource, which is especially characteristic in cases of the development of damage accumulation processes localised near various defects in the metal structure.…”

Positron Spectroscopy of Hydrogen-Loaded Ti-6Al-4V Alloy with Different Defect Structure

The defect structure of annealed cast, electron beam melted and ultrafine-grained titanium Ti-6Al-4V alloys before and after hydrogenation was studied. It has been established that before hydrogenation the predominant types of defects in electron beam melted and ultrafine-grained titanium alloy are dislocations and low-angle boundaries, respectively. The cast alloy after annealing is defect-free material. Hydrogenation from the gas phase to 1.00 ± 0.15 wt% leads to an increase of the concentration of the predominant type of defects. Moreover, vacancy complexes also presented in electron beam melted and ultrafine-grained Ti-6Al-4V alloys interact with hydrogen and form hydrogen-vacancy complexes.

“…Hydrogen accumulators are investigated for maximum storage capacity [2], the conditions for the introduction and withdrawal of hydrogen and the number of such cycles are studied [3]. In nuclear power engineering and in those industries where such hydride-forming materials as zirconium alloys [4], various grades of steel [5], titanium alloys [6] are subjected to hydrogenation…”

Metal hydrides are one of the types of functional materials that allow safe and compact storage of a large amount of hydrogen, which is increasingly used today as an alternate fuel or energy source. The possibility of obtaining the initial energy necessary for the production of hydrogen by electrolysis process from renewable energy sources, such as solar panels and wind generators, makes hydrogen energetic quite attractive and rapidly developing industry sector. Solid form of hydrogen storage with the possibility of reversible sorption, gives opportunity for creation autonomous energy storage systems. La-Ni based alloys allow hydrogen storing at ambient temperatures and pressure not higher than 15 bar, which makes the application of these alloys quite practical, interesting and prospects for analysis and modifications on the ways of stored hydrogen capacity increasing, alloys price reducing and application for renewable energy storage.
