The article discusses the projected rise of clean hydrogen demand in the Walls scenario, indicating a shift towards sustainable energy sources. Clean hydrogen is expected to see a substantial increase from its current near-zero levels to almost 200 million tonnes of oil equivalent (Mtoe) by 2050. This surge in demand underscores the increasing importance of hydrogen in the global energy transition towards cleaner and greener alternatives. The positive sentiment towards hydrogen in this scenario aligns with the broader efforts to reduce carbon emissions and combat climate change. As countries and industries seek to decarbonize and achieve net-zero emissions, the growth of clean hydrogen usage plays a crucial role in fostering a more sustainable future. The article highlights the potential for hydrogen to play a significant part in transforming the energy landscape and driving the adoption of renewable energy technologies. Overall, the projected increase in clean hydrogen demand signifies a step in the right direction towards achieving environmental goals and promoting a greener economy.
