Governments and industries are increasingly turning to hydrogen as a sustainable energy source to combat greenhouse gas emissions. The Boston Consulting Group highlights low-carbon hydrogen's pivotal role in decarbonizing industries like aviation, steel, and shipping. While hydrogen is environmentally friendly when burned, its leakage can indirectly contribute to global warming. Energy experts stress the importance of enhancing hydrogen leakage detection technology. Fixed gas detectors are recommended to monitor and prevent leaks across the hydrogen value chain, safeguarding the environment and workers. Various forms of hydrogen production exist, with gray hydrogen being the most common but the focus shifting towards blue and green hydrogen. Initiatives in steel, fertilizer, and petroleum refining sectors showcase the transition to clean hydrogen solutions. Examples include Tata Steel's hydrogen trial in steel production and the Yuri Renewable Hydrogen to Ammonia Project. These initiatives aim to significantly reduce emissions and combat climate change.
