Abstract

Abstract: Apart from being a major feedstock for chemical production, hydrogen is also a very promising energy carrier for the future energy. Currently hydrogen is predominantly produced via fossil routes, but as green energy sources are gaining a larger role in the energy mix, novel and green production routes are emerging. The most abundant renewable hydrogen sources are water and biomass, which allow several possible processing routes, such as electrolysis, thermochemical cycles and gasification. By introducing heat to the process the required electricity demand can be reduced (high temperature electrolysis) or practically eliminated (thermochemical cycles). Each renewable hydrogen production route has its own strength and weaknesses; the choice of the most suitable method is always dependent on the economical potentials and the location. The aim of this paper is to evaluate the different high temperature, renewable hydrogen production technologies. Graphical abstract: Image 1 Highlights: Today 85% of world's energy is fossil based; in future larger share for renewables. Using high temperature processes reduces the electricity demand. Most promising renewable ways: electrolysis, thermochemical cycles, BM gasification. Shift to renewable technologies in the long term scenario.
