Hydrogen Storage and Conversion

New Landmark Review Published in Nature Reviews Clean Energy

Hydrogen has the highest gravimetric energy density of any energy carriers, it can operate in a closed cycle with no carbon emissions and will play an important role as a secondary energy carrier in the future. What problems have already been solved, and what challenges still need to be addressed to ensure efficient and safe transportation as well as safe storage, and use of hydrogen? In a landmark review article, Claudia Weidenthaler, Michael Felderhoff, and experts from Task 40 of the International Energy Agency (IEA) summarized current and future research activities on these topics.

Their article, “Hydrogen-based materials for energy storage and conversion,” has just been published in Nature Reviews Clean Energy, offering a timely and authoritative overview of cutting-edge research. From novel solid-state storage materials to advanced catalysts for ammonia decomposition: This review article provides an overview of the current state of research, highlights breakthroughs, and examines the open questions that will shape the future of hydrogen technology.

The IEA task 40 is part of the International Energy Agency (IEA) Hydrogen Technology Collaboration Programme (TCP). The TCP is a unique global network of scientific experts that drives cutting-edge energy technology research through international cooperation.

You’ll find this article alongside other review articles, perspectives, and opinions on hydrogen from experts in materials science, engineering, and society.
