Introduction
Hydrogen is receiving more and more attention in Europe and around the world. The most important aspect is the fact that the energy recovery of green hydrogen in fuel cells produces no air emissions. Thus, it represents a possible solution to partially decarbonize industrial processes and economic sectors.
In the field of transport infrastructure, it is necessary to focus on alternative fuels and systems that will be created from renewable energy sources. Of course, these systems will also support the reduction of greenhouse gases. Currently, two technological platforms appear as long-term fuel sources, for example electromobility and hydrogen transport systems. Today, Slovakia has a commitment that more than 20% of vehicles in public administration should be free of combustion emissions in 2021.
Currently, hydrogen fuel is stored at extremely high pressures of 35-95 MPa. Today, there are options for storing hydrogen in various compounds that provide better storage options.
The implementation of hydrogen technologies with metal hydride reservoirs provides scope for increasing the safety and storage of H2 at lower pressures. To be able to use this type of hydrogen storage, it is necessary to design a reservoir that will meet the working conditions.
Conclusion
The main task of this work was to design a two-wheeled device that uses a type of hydrogen storage based on absorption into the metal alloy structure. It is also a hybrid two-wheeled device using a fuel cell and an electric motor, whose estimated range based on calculations is approximately 75 km. The next step of this work will be the construction of a real functional prototype and subsequent testing of the designed metal hydride vessels in this device.
