7 Green Hydrogen from Power-to-Gas can directly lead to significant Greenhouse gas (GHG) reductions Hydrogen (H 2 ) GHG-Emissions CO 2 reduction total for a 20 MW PtG-installation Land Use GHG values in gco 2-eq. /MJ SMR² 20 MW PtG 4 762,000 Land use in ha -91% GHG emissions 280, tco 2 ³ tco 2 ³ 4 H 2 from SMR² H 2 from PtG 4 [FQD] 1 [FQD] 1 H 2 from PtG 4 [estimated for PEM 5 ] tco 2 reduction per year Bioethanol 7 Biodiesel 8 H 2 from PtG 4 GHG count for Green Hydrogen is reduced by 91% compared to hydrogen produced via SMR² out of natural gas tons of CO 2 will be reduced by using a 20 MW Power-to-Gas electrolysis. Green Hydrogen requires significantly less land than other biofuels. 1 Default value of the life cycle GHG intensity according to Annex I of Council Directive COM (2014) 617 [FQD]. 2 Steam Methane Reforming - Conventional production process for hydrogen out of natural gas. ³ Total emission for the production of 3,43 Mio. Nm³H 2 per year. That equates the amount of hydrogen produces with a 20 MW Power-to-Gas installation at 80% availability per year. CO 2 default value according to Annex I of the Council Directive COM (2014) 617 [FQD]. 4 Power-to-Gas. 5 Proton Exchange Membrane. 6 Required surface for the production of 0.5 % of final energy consumption of German road transport (= 3.09 x 10 6 MWh) 7 average of absolute land use of sugar beets, wheat and corn basis respectively: sugar beets basis 40 GJ/ha = 11.1 MWh/ha, wheat basis 8.8 GJ / ha = 2.44 MWh / ha, corn basis 15 GJ / ha = 4.17 MWh / ha 8 on raps basis: 1000 kg/ha with 40 MJ/kg = 40 GJ/ha = 11.1 MWh/ha; 5 GHG = Green House Gas Emissions

9 Green Hydrogen for refineries can open doors to hydrogen economy 1 Cost efficient rollout Green Hydrogen for refineries Reduce emissions and provide flexibility for the electricity grid No need for infrastructural investments Cost reductions for electrolyzers Efficiency improvements Kick-start for a Power-to-Gas industry in the EU 2 Spill-over to other applications Green Hydrogen for industries Substantial emission reductions Limited infrastructure changes Green Hydrogen mobility Scaling up hydrogen mobility (fueling stations, cars, trains) Alternative to battery vehicles 3 Industrialization new economy emerges Green Hydrogen economy Utilization of natural gas infrastructure directly or after methanation Re-electrification makes from PtG a flexible back-up for Renewables Development of hydrogen infrastructure in form of grids and storage ? Usage of PtG in refinery process will accelerate technology development, reduce cost and enable deployment in other industries and in transport
