Japanese scientists from the RIKEN Institute of Physical and Chemical Research have announced a breakthrough in the field of hydrogen fuel storage and utilization. They have discovered a method for the efficient transportation of hydride ions (H-) under ambient conditions, which could greatly facilitate the production of safe, high-capacity, and efficient batteries and fuel cells.
Hydrogen is considered an ideal fuel because its combustion only produces water. However, storing hydrogen and extracting energy from it has been a challenge so far. Hydrogen fuel cells, used in some vehicles, require special membranes and continuous system watering, among other things.
The Japanese scientists decided to utilize hydrogen in a different form, as hydride ions in solid bodies, with an additional electron. The material they developed, based on lanthanum hydride with the addition of strontium atoms, allows for easy capture, transfer, and release of hydrogen ions. This is a significant discovery that could lead to the development of solid electrolytes that conduct hydride ions.
The scientists plan to conduct further research to enhance the efficiency of their invention and create a material that will reversibly capture and release hydrogen. Such a material would enable the creation of rechargeable hydrogen batteries and improved hydrogen storage tanks.
This groundbreaking discovery has the potential to change the future of energy, contributing to the development of eco-friendly energy sources and the reduction of CO2 emissions.
