Research Summary

Naoki  Uchiyama(Ph.D.) Daigo Miyajima

RIKEN developed the first highly ordered graphitic carbon nitride film. With this new technology, we tackle to develop a novel porous material featuring ultra-high hydrogen storage capacity and excellent hydrogen desorption. We believe that our challenge can reduce the size of conventional hydrogen storage tanks by half. Furthermore, we will realize a flat tank for hydrogen storage and reduce hydrogen filling pressure.
