Equinor ASA
Norwegian state energy company (Oslo Stock Exchange: EQNR; 67% owned by Norwegian government, HQ Stavanger; ~$150B revenue); world's 5th-largest natural gas supplier and the dominant supplier of natural gas to Europe via Norwegian North Sea pipeline infrastructure (Gassled pipeline network). Following Russia's invasion of Ukraine in February 2022 and the subsequent sanctions on Russian gas (Gazprom), Equinor became the single most important gas supplier to continental Europe — Norway replaced Russia as Europe's largest gas supplier in 2022. For industrial gas companies (Linde, Air Liquide, Air Products European operations) using natural gas for Steam Methane Reforming (SMR) hydrogen production, Equinor's Norwegian pipeline gas is the critical feedstock. Equinor also operates in the US (Marcellus shale, Gulf of Mexico), Angola, Brazil, and Canada. The Norwegian government's 67% stake means European industrial hydrogen supply depends significantly on Norwegian state energy policy decisions.
