On March 5, 2021, the 2021 State Council Government Work Report pointed out that it should do a good job in carbon peaking and carbon neutrality, formulate an action plan for peaking carbon emissions by 2030, and optimize the industrial structure and energy structure
.
Hydrogen energy can well realize the transition from high-carbon to low-carbon.
With the continuous acceleration of hydrogen energy development, hydrogen energy will shoulder the important mission of achieving carbon neutrality
"How to better store and use hydrogen energy" is a question that scientists have been working hard to study
.
Traditional hydrogen storage and transportation are mainly realized by high-pressure gaseous method or low-temperature liquid method.
The high-pressure gaseous method has high requirements on the quality of the container, is likely to cause hydrogen leakage, and has low safety
In response to the above problems, the team of Professor Zhang Jinying from the School of Electrical Engineering of Xi’an Jiaotong University developed a graphene interface nanovalve solid hydrogen storage material.
Using highly active light metal hydrides as raw materials, a graphene interface nanovalve structure was established at the interface of different components.
The non-catalytic kinetic regulation mechanism realizes the safe, controllable and stable hydrogen release of hydrogen storage materials
.
At the same time, the interface nano valve structure can effectively isolate water and oxygen, prevent spontaneous hydrogen leakage, improve the safety of storage and transportation of materials, avoid the use of bulky high-pressure metal tanks or add additional protective devices for transportation, and greatly improve the portability of materials And the hydrogen storage density of the system
