Scientists in Japan, particularly from Tokyo Institute of Technology and Tokyo University of Science, have made significant progress in solving the challenge of hydrogen storage through the development of a novel compound named 1a. Led by Associate Professor Kosuke Ono, the research team has successfully created a crystalline solid, 1a (N), that efficiently adsorbs and desorbs ammonia (NH3). This breakthrough offers a practical solution to the difficulties associated with storing and transporting hydrogen gas. NH3, being an alternative to hydrogen, presents several advantages such as not requiring cold storage or high pressure, utilizing existing industrial infrastructure, and producing environmentally friendly by-products upon combustion. The innovative material, 1a (N), with its CO2H functional groups in parallel nanochannels, allows for high-density NH3 adsorption at room temperature, with easy release through a simple decompression process. This advancement not only improves NH3 storage efficiency but also opens up possibilities for adsorbing other reactive gases, potentially expanding its applications in sustainable energy storage and beyond. The research findings have been published in the Journal of the American Chemical Society, showcasing the promising future of NH3 as an energy carrier and the potential for sustainable hydrogen economies.
