LONGi Green Energy Technology Company, known for its success in solar power, has expanded into green hydrogen production through LONGi Hydrogen Energy Technology Company. Despite its small revenue contribution, green hydrogen is seen as crucial for decarbonization efforts across various industries. The global demand for hydrogen is forecasted to rise substantially, prompting investments from major companies like Saudi Aramco, NextEra Energy, and BP. The development of low-carbon steel plants further illustrates the growing interest in green hydrogen technologies. However, challenges such as high costs and infrastructure limitations persist, highlighting the need for policy support and technological advancements. Green hydrogen, although currently a small fraction of the energy market, is positioned to play a pivotal role in the transition to a greener economy. Incorporating hydrogen into existing energy systems is already underway, but significant changes are required to shift from grey hydrogen production to cleaner green hydrogen processes.
