Abstract

Povećana integracija obnovljivih izvora energije u elektroenergetski sustav i dekarbonizacija energetskih i industrijskih procesa otvara nove mogućnosti primjene tehnologija proizvodnje, pohrane i korištenja vodika.
Vodik se može koristiti u smjesi goriva plinskih kogeneracija. Za to je potrebno instalirati elektrolizator i spremnik vodika za proizvodnju vodika na licu mjesta za plinsku turbinu. Kada su cijene električne energije niske, elektrolizator će proizvoditi vodik, a kada su visoke,... More vodik će se koristiti u plinskoj turbini za proizvodnju električne energije i za namirenje toplinskog tereta.
Zbog visokih kapitalnih troškova elektrolizatora i niskih cijena emisija CO2 i prirodnog plina, investicija u prenamjenu kogeneracijskog postrojenja na postrojenje koje koristi vodik upitne je isplativosti. Less

Abstract (english)

The increased integration of renewable energy sources into the power system and
the decarbonization of energy and industrial processes open up new possibilities for
the application of hydrogen production, storage, and utilization technologies.
Hydrogen can be used in the fuel mixture of gas-fred cogeneration plants. This requires the installation of an electrolyzer and a hydrogen storage tank for on-site hydrogen production for the gas turbine. When electricity prices are low, the... More electrolyzer will produce hydrogen, and when prices are high, hydrogen will be used in the gas turbine for electricity generation and meeting the thermal load.
However, due to the high capital costs of the electrolyzer and the low prices of CO2 emissions and natural gas, the investment in converting a cogeneration plant to a hydrogen-based facility raises questions about cost-effectiveness. Less
