Power-to-Gas: Die Rolle der chemischen Speicherung in einem Energiesystem mit hohen Anteilen an erneuerbarer Energie

Abstract: Die Umstellung der Energieversorgung auf erneuerbare Quellen (Wind, Photovoltaik) wird in Zukunft verstärkt die Volatilität in der Stromerzeugung erhöhen. Um eine ausgeglichene Leistungsbilanz im Stromnetz sicherzustellen, werden Speicher benötigt -nicht nur kurzzeitig, sondern auch saisonal. Die bidirektionale Kopplung bestehender Energieinfrastruktur mit dem Stromnetz kann hier Abhilfe schaffen, indem der Strom in Elektrolyseanlagen zur Wasserstofferzeugung genutzt wird. Der Wasserstoff kann Erdgas in der vo… Show more

“…The CH 4 formation rates could be increased when applying high cycling frequencies and a stoichiometric cycle-split ratio, but optimal rates were always achieved with steady state values. Lehner et al (2017) concluded that for synthesising steelworks gases to methane a load flexible reactor setup is favourable to meet the fluctuations in process gas and hydrogen availability. Hauser et al (2021) performed steady state and dynamic methanation experiments with synthetic gases from the steelworks industry using a structured reactor with a heat pipe cooling system.…”

“…In addition, the significant amount of catalyst poisons present in the already cleaned by-product gases needs to be addressed. Lehner et al [11] added that, for converting steelworks gases to methane, a load flexible reactor setup is favourable to meet the fluctuations in the process gas and hydrogen availability.…”

“…Although the applicability of steelworks gases as feed for the synthesis of methane was addressed and confirmed by multiple authors [7][8][9][10][11], experiments with real gases, including contaminations poisonous to catalysts, have not yet been performed. Consequently, the main aim of this work is to show the degree of degradation when using real BFG and BOFG (including nitrogen) as an input for a methanation unit in a composition, as given in Table 1, as well as to present a working solution to overcome the problem of catalyst deactivation.…”

“…The additional hydrogen is needed for the conversion of a majority of the carbon dioxide which is part of the steel mill exhaust gases. Furthermore, hydrogen is considered to be a key component for other "carbon to chemicals" and "power to gas" applications and could be a competitive energy carrier for the energy transition from fossil to renewable sources .…”
