Accelerating process of the transport and energy sectors increases the interest in fuels derived from renewable sources. The predicted three-fold increase in hydrogen production by 2050, driven by its falling production costs, justifies the direction of research aimed at its popularisation as a fuel for internal combustion engines (H2ICE). Presented article provides an overview of the state of knowledge on hydrogen combustion systems, which are currently the most attractive development path, mainly due to the well-developed production technology and relatively low recycling cost compared with fuel cells. The paper contains a comprehensive analysis of currently available solutions covering issues related to the production, storage, and transmission of hydrogen, with particular emphasis on the Polish market, which is one of the largest in Europe in terms of its production. The authors also propose their own concept of a hydrogen combustion system for application in an internal combustion engine. The presented solution is based on the idea of prechamber introduction in order to improve combustion process parameters and hence overall engine efficiency.

“…NO 2 is a globally regulated air pollutant that is harmful to one's health and which, in turn, contributes to photochemical ozone pollution and particulate matter (PM2.5). [Stępień et al 2021, Stępień 2021, Brzeżański et al 2013.…”

“…However, there is a risk that the adoption of hydrogen as a combustion fuel, if not properly managed, may lead to some unintended consequences due to the co-emission of harmful NOx. Ciniviz and Brzeżański in the articles [Ciniviz et al 2012, Brzeżański et al 2013 Thanks to the dilution effect, EGR effectively reduces NOx emissions, where the oxygen concentration in the intake decreases. Furthermore, a significant decrease in volumetric efficiency is observed as EGR rates increase (reductions of approximately 15% are noted compared to dual-fuel hydrogen without EGR).…”

Hydrogen is expected to be one of the most important fuels meeting stringent emission standards shortly. Using hydrogen as a fuel in an internal combustion engine (ICE) is an alternative application to replace hydrocarbon fuels that, when burned, produce harmful gases such as carbon monoxide and hydrocarbons, particulate matter, and greenhouse gases. This work provides an overview of the latest research results and future challenges and opportunities related to the use of hydrogen to power ICEs. The article presents the work of various research centres describing the technical use of hydrogen as a fuel in motor vehicles with combustion engines. Specific chemical and physical properties of hydrogen used in combustion engines were presented. The article presents modern research on a hydrogen-powered ICE. First, the basics of hydrogen engines are described, examining the engine-specific properties of hydrogen, followed by a review of the existing literature. Attention was paid to the fundamental importance of optimising the air composition from the point of view of combustion quality, NOx emissions, engine efficiency, and performance. Another issue under consideration is cleaning exhaust gases to meet future emissions regulations for hydrogen-fuelled combustion engines.

“…7) assumes the formation of a lean or ultra-lean mixture in the space of the main combustion chamber by means of indirect hydrogen injection. It is also considered to apply direct injection system in the future as it gives better results in real conditions tests [4]. In the space of the preliminary chamber, the volume of which Possible applications of prechambers in hydrogen internal combustion engines is assumed to be a few percent of the volume of the main chamber, integrated with the cylinder head, the ignition of the stoichiometric or lean mixture is initiated.…”

The use of hydrogen as a fuel for an internal combustion engines has caused many problems for years, the most significant of which seems to be the excessive emission of nitrogen oxides and the tendency to knock combustion. In order to ensure better control of the combustion process in a internal combustion engine powered by hydrogen, it has been proposed to use a split combustion chamber solution. Following paper contains a description of a hydrogen combustion system that includes an analysis of possible technical solutions. The considerations take into account the issues of the dual nature of hydrogen knocking and the problem of burning a stratified charge of a hydrogen-air mixture in a cylinder.
