Green hydrogen has a wide range of applications across various industries, driving decarbonization efforts globally. In the transportation sector, it powers fuel cell vehicles (FCVs), including passenger cars, trucks, and drones, emitting only water vapor and eliminating tailpipe emissions. Industrial applications are equally significant: it serves as a clean alternative to fossil fuels in steelmaking (replacing coke), reducing carbon emissions from one of the most energy-intensive industries. In chemical manufacturing, green hydrogen is used in ammonia production, a key component in fertilizers, and in refining processes to reduce reliance on fossil-based hydrogen. For residential and commercial use, it can be integrated into home energy systems, where excess solar energy is converted to hydrogen via electrolysis, stored, and later used for electricity or heating through fuel cells. Additionally, green hydrogen can generate electricity in stationary fuel cell power plants, supporting grid stability and providing backup power, further solidifying its role as a multi-purpose clean energy solution.
