Prerequisites for a competitive hydrogen economy: Promoting and inhibiting factors in the transport sector and the chemical industry

Abstract:

From today's perspective, the use of hydrogen is inevitable in order to achieve the climate protection goals. At the moment, however, hydrogen hardly plays a role for direct use or for further processing in the energy system. CO2-free hydrogen, which is produced on the basis of renewable energies ("green" hydrogen), is sustainable in the long term. For the rapid market ramp-up of hydrogen technologies for decarbonization in various application areas, CO2-neutral ("blue") hydrogen will also have to play a role for economic reasons. An important lever for the use of hydrogen in transport is lowering the price of hydrogen in order to make fuel cell mobility economical. In mobile applications, fuel cells are in direct competition with battery technology. The high burden of electricity with duties and taxes currently limits the increased use of hydrogen from renewable energies z. B. in the areas of traffic, chemistry and as energy storage. The target model for the regulatory framework should lead to both an economically efficient overall system and an extensive internalization of environmental costs (e.g. through CO2 emissions). It is basically to be designed in a technology-neutral manner. [...]
