The report titled 'Turning hydrogen demand into reality: Which sectors come first?' delves into the transformative potential of clean hydrogen as an energy carrier and feedstock to decarbonize various sectors, particularly hard-to-abate sectors. Authored by a Professor of Energy Economics at Biberach University of Applied Sciences in Germany, in collaboration with another expert from the same university, the report emphasizes the scale of renewable electricity demand required for green hydrogen production, presenting both unprecedented opportunities and challenges. It predicts that heavy industries will drive global hydrogen demand until 2050, focusing on markets like South Korea, Japan, and Europe. The report also discusses the volatility and uncertainty in current hydrogen demand scenarios, emphasizing the need for strategic planning to navigate the evolving landscape. By highlighting the necessity of up to 411 new hydrogen vessels and significant electricity capacity to meet global green hydrogen demand, the report underscores the immense potential and implications of transitioning to clean hydrogen for a sustainable future.
