Hydrogen as a green secondary of energy is one of the most promising solutions for our future energy supply. Hydrogen can be ideally used as a link between the energy sectors of electricity, heat and mobility and reduces the use of fossil energy sources in present. Green hydrogen production will fundamentally change our energy economy.
Fuel cells as an energy conversion system with Hydrogen increase the overall efficiency, reducing greenhouse gas emissions and the dependencies of fossil energy sources.
This article shows the context between the primary energy sources and fuel cell applications. The efficiency chain and the environment dependencies are explained unequivocally. The aim of the scientific paper is to show the possible consequences of environmental impacts using hydrogen as an energy source in hydrogen business applications.
Methodologically the proposed model is used on two case studies, to determine greenhouse gas emissions to reveal the different dependency of fuel and application. The latest data's of hydrogen production and fuel cell applications are implemented in the model.
The results of the research show the crucial aspects to use hydrogen as a secondary energy carrier in two case studies. The results can help all groups and institutions that want to deal with hydrogen and their energy conversion processes to get a better understanding from an environmental and technical view.
