Decarbonizing the global economy by mid-century is crucial in the fight against climate change, necessitating a major shift in energy systems. Hydrogen has emerged as a viable long-term solution to reduce emissions in carbon-intensive sectors like power generation, transport, steel, and cement. Green hydrogen, produced through electrolysis using renewable energy sources, offers a low-carbon alternative to grey hydrogen derived from fossil fuels. China showcases significant advancements in green hydrogen adoption, particularly in fuel-cell vehicles and heavy-duty transport, with over 30 large-scale projects underway. These projects, backed by substantial investments, aim to leverage China's renewable energy resources for sustainable hydrogen production. Despite challenges such as high costs and technical complexities, ongoing research and development focus on enhancing efficiency and driving commercialization. Green hydrogen presents promising opportunities in various sectors like steel production, offering a cleaner and more energy-efficient alternative. The article highlights key pilot projects in China, including a solar-powered green hydrogen plant by China Petroleum & Chemical and a project by China Huadian Group in Baotou. Investors show a growing interest in green hydrogen opportunities, signaling a positive outlook towards the potential of hydrogen as a sustainable energy source.
