Tehno-ekonomska analiza proizvodnje vodonika iz biodizela i njegove upotrebe za proizvodnju električne energije u gorivnim ćelijama za pogon električnih vozila

Abstract

One of the possible directions of decarbonisation and electrification of freight and passenger transport is the use of fuel cells with hydrogen as a fuel. Considering that the use of biomass for electricity generation is largely uncompetitive compared to wind and solar power plants, its use for hydrogen production is one of the possible directions of development of this renewable energy source. In this paper, technologies for hydrogen production from biodiesel were analyzed. An analysis of the structure and total costs of hydrogen production from biodiesel was performed, as well as the energy balance of this process. The conditions of using hydrogen to drive fuel cells in electric vehicles were considered. The efficiency of the energy cycle analysis was performed: biodiesel - hydrogen - electricity - mechanical energy to drive electric vehicles. As a final result, an estimation of the costs of production of kWh of electricity from biodiesel and a comparative analysis with a vehicle powered by a diesel engine and an electric motor powered by batteries was performed.
