STUDIES REGARDING THE ENERGETIC PROPERTIES OF HYDROGEN AND METHANE MIXTURES FOR DOMESTIC AND INDUSTRIAL APPLICATIONS

One of today's world challenges is represented by the implementation of greenhouse gases free technologies, in which the utilisation of hydrogen as energy vector is an essential element in order to obtain a sustainable global development. Natural gas (methane) represents the most important energy source in Europe, being used in electric energy production, in residential and commercial sectors, and also for transportation. Being responsible for a significant part of the carbon dioxide emissions, the elimination of its utilisation in these sectors represents a major challenge. A viable solution for reducing the dependency on fossil fuels is to use different hydrogen and methane mixtures in energy production, having as result a decrease of greenhouse gases emissions into the atmosphere. This work addresses some issues regarding of transition from the present system that utilises methane gas towards a system completely based on hydrogen. A literature review is done in view of identifying the properties of these mixtures for the characterisation of its combustion in a premixed flame burner. Properties like, laminar burning velocity, the behaviour of adiabatic flame temperature and the concentration limits of flame propagation, are evaluated for future use of hydrogen and methane mixture in the domestic and industrial sector. The evaluation is done by simulating the combustion in a premixed flame burner, providing data about the effect of adding hydrogen into methane.
