How Power-to-Gas strategy could reduce national Natural Gas consumption over the energy crisis period

Abstract Europe is facing an energy crisis caused by the dramatic rise in gas prices. This situation damaging European economy and urgent measures to reduce consumption are crucial short term. paper aims analyse potential contribution of Power-to-Gas strategy Italian Natural Gas (NG) context current crisis. To do so, system has been modelled means EnergyPLAN software. The electrolysers’ installation systems simulated combination with different levels additional RES installation. hydrogen production NG abatement have calculated each scenario. Furthermore, Abatement Cost (NGAC) assessed. By installing 1.5 GW electrolysers, along 25 renewables, about 140 ktonH2/year can be produced only exploiting excess. total reduction due both generation injection more than 60 TWh/year. cost varies between 45 54 €/MWh. At prices, it therefore extremely cheaper invest a drastic natural buy same amount on wholesale market. Therefore, opportunity accelerate transition process. proposed solutions allow substantial consequent emissions country’s dependency.
