(Phys.org)—By using solar energy to reversibly attach and detach hydrogen atoms on a 6-carbon ring called benzene,scientists occupy developed a simple and efficient method to store, transport, or release hydrogen potentially on a large scale. The hydrogen storage problem is currently one of the biggest challenges facing the development of hydrogen as a widespread energy carrier,and the researchers hope that the unusual strategy may lead to a safe and inexpensive solution to this problem.
