Coca-Cola has revealed its plans to unveil the world's first hydrogen-powered vending machines at the upcoming World Expo 2025 in Osaka, Japan. Developed in partnership with Fuji Electric, these machines will not rely on traditional power sources but will use replaceable hydrogen cartridges to generate electricity through a chemical reaction involving oxygen. The machines, equipped with an additional generator module, will educate visitors about hydrogen power. Despite the innovative approach, questions remain about the efficiency and sustainability of the project, especially regarding the duration of the hydrogen cartridges. While the announcement has sparked a range of reactions on social media, with some expressing doubt about the environmental impact and others recognizing the potential benefits for the vending industry, the success of this initiative will hinge on overcoming challenges related to hydrogen supply infrastructure and cost-effectiveness for wider implementation.
