Hydrogen, an age-old fuel concept dating back to pre-World War II, is experiencing a resurgence in the modern energy landscape. Initially patented for use in cars in the USA by a German emigrant, hydrogen has evolved from a niche idea to a potential game-changer in global energy markets. Japan's early experimentation with water-fueled cars in the 1960s hinted at hydrogen's promise, though widespread adoption was elusive. Today, Ilham Shabanov, an energy expert, highlights the green and blue production methods of hydrogen, emphasizing the environmental benefits of electrolysis from renewable sources. While green hydrogen, obtained from water, is deemed environmentally friendly, blue hydrogen from natural gas involves carbon capture and storage to mitigate emissions. Azerbaijan, rich in gas reserves, is poised to tap into its energy potential, transitioning to hydrogen to meet the evolving energy demands and environmental regulations. By increasing the production and export of green energy, including hydrogen and electricity, Azerbaijan aims to play a significant role in the global energy market. However, challenges such as hydrogen transportation remain, with solutions like blending it with natural gas or exploring alternative transport methods like tanker shipping. Despite obstacles, the positive sentiment towards hydrogen as an alternative fuel source prevails, with the EU investing substantially in research and development to drive the hydrogen economy forward.
