Ekonomická efektivnost ukládání energie do vodíku pomocí katalyzátoru z karbidu wolframu

Abstract

In this thesis, cubic tungsten carbide was studied: methods of its synthesis (possible and used), its application in energy storage through electrolysis, other possible ways of energy storage, as well as the economic efficiency of these technologies. Unfortunately, cubic tungsten carbide at this stage of development proved to be economically inefficient: the gain in capital investments does not offset the increase in operating costs. The material needs further study and development. Sensitivity analysis of electrolysis and methane reforming steam was also performed. For electrolysis, efficiency remains a key parameter. In the past (2018), a significant increase in the cost of gas was required in order for the production of green hydrogen to be cost-effective. At the moment (2022) economically viable production of hydrogen through electrolysis looks possible
