N2 - Hydrogen is an attractive future energy source. Developing a hydrogen carrier, without any safety risk, i.e., high pressure and toxicity, is an urgent issue. Herein we present a fluorenone/fluorenol polymer sheet as a hydrogen carrier featuring high safety, moldability, and ease of handling. An iridium catalyst allows the polymer sheet to fix and release hydrogen gas under milder conditions (< 100 °C and ambient pressure), compared to those required by other hydrogen carriers. The polymer sheet, swollen with a small amount of water including the iridium complex catalyst, was hydrogenated at 25 °C and ambient hydrogen pressure, stored hydrogen via chemical bond formation, and then released it within 5 h when simply being warmed to 95 °C.
