Description
Satisfying the rapidly growing needs for green energy supply is the challenge of today’s science. The project aims at the development of clean energy storage systems based on hydrogen as an energy carrier. The main objective of this project is to develop the modern hydrogen storage tank. The novel nanomaterials based on titanium-nickel and titanium-magnesium multicomponent alloys will be synthesised, optimised and used for this purpose.The intended outcomes of the project are to develop the cost and performance-efficient nanomaterials for environment-friendly energy storage, to support the wider usage of renewable energy and increase the popularity of the cost-efficient energy storage solutions. The increased hydrogen capacity for the developed nanomaterials will be achieved. The nanomaterials will exhibit better applications-related properties.
Summary of project results
General conclusions that can be drawn are of a bimodal nature. At first, it was shown that it is possible to produce the amorphous or icosahedral hydrides on a routine basis using a standard procedure that seems to be suitable for the Ti-Zr-Ni based alloys. The completed basic research extended the current knowledge related to the amorphous materials, encouraging to search for different compositions (e.g. Mg-based materials, alanates, etc.). Moreover, the results revealed that the nanostructure of the active material is of the utmost importance for tailoring of the reaction kinetics and enthalpy of the hydrides formation. On the other hand, the project succeed in defining the problems that must be overcome before the ready-to-use hydrogen storage system is constructed. The developed, quantitative, live neutron imaging technique of the operating hydrogen storage containers provided the first-hand information about the processes inside of the container. Those achievements enable launching a collaboration with the other groups working on the constructions of hydrogen storage tanks. It is worth mentioning that that technique was successfully applied to the other types of hydrogen storage containers giving very important hints for their further optimisation. That is a remarkable indicator of the project impact on the field of the hydrogen storage. The scientific collaboration between the research team and Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) in Dresden was established within the project. Due to that collaboration, the ideas that evolved from the project will be developed, especially those connected with the optimisation of the matrixes used for the nano-composites. Also, the invented solutions will be tested in real hydrogen storage systems in frame of their potential commercial application. Moreover, the results of the project account the general know-how, particularly those related to the obtained nano-composites and therefore might be implemented in all classes of nano-materials. Besides this, the systems for the in-situ tests that were designed in frame of the project, will provide the extremely important data that might applied for a wide variety of hydrogen storage nano-materials. In addition, the project results are a solid background with reference to the next grant applications.
