Green hydrogen, derived from renewable sources like wind, solar, and hydropower, is gaining prominence as a crucial element in the global energy transition. Unlike conventional hydrogen, green hydrogen is entirely emission-free, aligning with climate goals and offering a sustainable alternative for industries and governments. Through electrolysis, green hydrogen is produced by splitting water molecules using electricity from renewable sources, enabling its versatile applications in sectors such as transportation, heavy industry, and power generation. The global green hydrogen market is experiencing rapid growth, with a projected value of $89.2 billion by 2030, fueled by increasing demand, declining renewable energy costs, and government support. Europe leads in green hydrogen adoption, followed by Asia-Pacific and North America, each showcasing significant advancements and investments in the sector. Technological innovations, cost efficiency, and infrastructure developments are driving the expansion of the green hydrogen market, supported by public-private partnerships and a focus on creating sustainable supply chains.
