Hydrogen, the future of aviation

Maciorowski Damian, Ludwiczak Aleksandra, Kozakiewicz Adam

Combustion Engines

2024

R. 63, nr 2

126--131

One of the biggest challenges of modern aviation is the development of technologies that reduce or eliminate emissions of harmful combustion components into the atmosphere. European authorities are imposing increasingly stringent emissions regulations. Therefore, new models of combustion chambers, new combustion methods, as well as new types of aviation fuels must be developed. This article presents the possibilities of using hydrogen propulsion in aviation. The reasons for conducting research on hydrogen propulsion are discussed, as well as the history of the introduction of hydrogen propulsion into aircraft engines. Problems that can be encountered in the production and storage of hydrogen are identified and explained. Proposals for the use of hydrogen combustion or the use of fuel cells to power turbine engines are also presented, and the economic aspect of this type of fuel is discussed.

Types and applications of hydrogen fuel cells in transport

Gallas Dawid, Stobnicki Paweł, Bolzhelarskyi Yaroslav

Pojazdy Szynowe

2022

Nr 3-4

31--36

The article summarizes the types of hydrogen sources and the possibilities of using hydrogen in fuel cell technologies. The types of hydrogen fuel cells and solutions used in hydrogen powered drives were discussed. The current economic and ecological aspects affecting the possibilities and profitability of using various types of hydrogen as an alternative fuel in various forms of transport were analyzed, and forecasts for the development of this form of propulsion and power supply in transport for the coming years were presented. It was concluded that only a simultaneous increase in hydrogen production, through an increase in demand or technological development, combined with a decrease in the cost of hydrogen cells down to a level of at least $40/kW, would enable the proliferation of hydrogen technologies in all modes of transport.

Use of Hydrogen Fuel Cells in Rail Transport

Siwiec Jakub

Problemy Kolejnictwa

2021

Z. 190

125--131

The article presents the most technologically advanced alternative propulsion of rail vehicles that, at the same time, has great development potential, i.e. hydrogen fuel cells. The current condition of the rolling stock and electrification of the traction network is described, and domestic and foreign plans for the deployment of fuel cells are presented and accompanied by legislative work aimed at the application of environmentally friendly solutions.
