Green Hydrogen @ OMV (Technology Talk)

Green Hydrogen @ OMV Sorin Ivanovici OMV Downstream GmbH 23.10.2025 We continue our transformation toward an integrated energy, fuels and chemicals company –with a strong focus on value 2 Strategy 2030 Accelerate chemical growth through BGI, feedstock integration and driving circular innovation Strengthen profitable fuels business while capturing opportunities in sustainable mobility Net zero by 2050 in Scope 1, 2 and 3 High cash flow generation | Clear investment criteria | Attractive and reliable shareholder returns Grow gas and selectively advance renewables OMV GREEN HYDROGEN Green Hydrogen is an essential feedstock for reducing the Scope 1 emissions and the carbon footprint of all refinery products. It is key for the future production of synthetic fuels and chemical feedstocks 3 Synthetic Bio Chemicals Green Hydrogen e-Fuels syn. Chemicals HVO/SAF Other biofuels Sustainable & Renewable Chemicals Traditional feedstock Traditional Fuels & Chemical Feedstocks OMV GREEN HYDROGEN Green Hydrogen Value chain in OMV 4 Supports refinery decarbonization Improves profitability of traditional fuels Enhances renewable fuel cost effectiveness by lowering feedstock cost Further explore partnerships for green hydrogen and future drive innovation for e-fuels and e-chemicals Green H2 Green hydrogen drives value creation via supporting differentiated, higher-margin products OMV GREEN HYDROGEN •In Operation •Largest electrolyser in operation in AT •Under construction •Close to refinery Schwechat •Planned start of operation 2027 UpHyII is the largest electrolyzers in Austrian in operation, producing up to 1500 tpa Green Hydrogen in the refinery Schwechat OMV GREEN HYDROGEN •PEM electrolyser technology •4x2,5 MW process units •Up to 1.500t/a green hydrogen production (2000 Nm³/h with H2 quality of 99,999%) •Pressurized system >30bar •Supply with green electricity via Power Purchase Agreements (PPA) secured •CO2 savings of up to 15.000 t/a •Mechanical completion •Hot Commissioning finalized •Functional safety checked by TÜV Austria •RFNBO certification by TÜV Süd based on ISCC EU •Successful production of first H2 and delivery to the refinery network achieved April 2025 •Finalization of Site-Acceptance-Test (SAT) in Q4/2025 General project data Achievements Next steps UpHyLarge will reduce Scope 1 emissions, enable meeting the RFNBO product mandates and provides feedstock for potential future e-Methanol production in Schwechat 6 •To be installed electrolysis capacity: 140 MW •Nameplate capacity: 23 kta hydrogen •Location: Bruck a.d.
