报告题目∶Solid-State Hydrogen Storage
报告摘要：Hydrogen is one of the most promising clean energy sources in the future. It can transmit energy just like electricity, and after combustion, it only produces water, making it extremely environmentally friendly. However, hydrogen is also quite "mischievous" - it has a large volume, is not easy to compress, poses difficulties in transportation, and is prone to leakage. Therefore, how to store hydrogen safely and conveniently has always been a problem that scientists have been striving to solve.
This English lecture will introduce a brand-new method of hydrogen storage: Solid-state Hydrogen Storage. That is to say, it means "hiding" hydrogen in some very special materials. These materials, like sponges, have many tiny pores that can absorb hydrogen, greatly reducing the space occupied by hydrogen just like "compressed biscuits," and at the same time, it is safer.
We have used an advanced "in-situ neutron scattering technology," which is like an "X-ray perspective eye" and can observe the movement and changes of hydrogen within the materials. This technology has helped us capture, for the first time, the image of hydrogen existing in a solid state within these tiny pores, confirming the feasibility of this hydrogen storage method. More importantly, based on these research results, we have also designed some new materials that can store more hydrogen, with higher efficiency and greater convenience in use. This research not only provides new ideas for the widespread application of hydrogen energy but also takes an important step towards achieving a low-carbon and sustainable future energy system.
