Abstract: This paper presents a qualitative and quantitative feasibility analysis of the Power-to-Gas (PtG) technology in the future Swiss power grid which will be characterized by a significant share of intermittent renewable energy sources (RES), especially Photovoltaic (PV) energy.The Energy Strategy 2050 set forth by the Swiss federal government includes a plan of a strong expansion of renewable energy sources. PV, for example, shall make up one fifth of Switzerland’s total energy production in 2050. Such a drastic expansion rate of PV can lead to so-called reverse power flow in the low voltage (LV) grid, as indicated in a previous case study conducted in a Zürich area.This paper demonstrates the impact of the PtG technology through three different scenarios in the above-mentioned case. The scenarios are established with respect to the input energy source to the PtG plant. The PtG plant is integrated into the LV grid for absorbing the excess PV energy for producing hydrogen. For each scenario, the produced hydrogen is assumed to be sold in the mobility sector. The results of this simulation give the insights concerning the technical as well as economical feasibility of the integration of PtG into the existing LV grid.
