That hydrogen taxis have a future in and around Paris is not guaranteed: in mid-2025, a dispute erupted between HysetCo and its closely partnered hydrogen taxi operator Hype<\/a>. The latter subsequently announced a radical strategic shift towards battery-electric taxis, citing frustrating experiences with energy supply and sharply rising costs. The final straw was the insolvency of electrolyser manufacturer McPhy.<\/p>\n\n\n\n Hype was already operating hydrogen taxis in Paris before the joint venture HysetCo even existed: the Hype fleet has been active in the French capital since 2015. At the time, the goal was to expand this fleet to 600 hydrogen taxis by 2020. To achieve this, the founding members\u2014Air Liquide, Idex, Soci\u00e9t\u00e9 du Taxi \u00c9lectrique Parisien (STEP), and Toyota\u2014launched the joint venture HysetCo in February 2019<\/a>. TotalEnergies joined in 2021. However, the expansion of the Hype fleet did not gain significant momentum.<\/p>\n\n\n\n Over the years, HysetCo gradually distanced itself from Hype and increasingly specialised in Mobility-as-a-Service (MaaS) offerings for hydrogen mobility in and around Paris. In 2024, the joint venture stated that it delivers nearly 30 tonnes of H\u2082 to its customers each month and manages a fleet of over 500 hydrogen vehicles (including, but not limited to, Hype\u2019s hydrogen taxis). That same year, HysetCo raised \u20ac200 million in fresh capital and gained hydrogen fund Hy24 as its new largest shareholder.<\/p>\n\n\n\n Since 2015, Hype\u2019s operational business has been coordinated by the eponymous operator. Over the years, the two sides had clearly drifted apart. In any case, during the publicly aired dispute last summer, Hype openly criticised two of HysetCo\u2019s parent companies\u2014TotalEnergies and Air Liquide. While Hype is now focusing on battery-electric taxis, HysetCo can now count Uber\u2019s entry as a success.<\/p>\n\n\n\n
