Since the 1970s, hydrogen has been recognized as an ideal alternative energy carrier for fossil fuels. The burning of hydrogen will not release greenhouse gases and toxic pollutants. It will only produce water. This feature allows hydrogen to be given more hope as a clean, environmentally friendly renewable energy source. However, we have not yet entered the era of hydrogen economy. This is because there are huge loopholes and deficiencies in the safe and intensive hydrogen storage technology. All along, the United States, Japan, Germany, the United Kingdom, Switzerland, Canada, and other countries have conducted a lot of research work on hydrogen storage technology. Recently, good news finally came. American scientists have successfully invented a new nano-scale composite material that can safely and densely store hydrogen and keep hydrogen in a stable state so that users can easily extract hydrogen for power generation. The materials currently used in the market contain a limited amount of hydrogen, and the conditions of use are also very demanding. Ultra-low or ultra-high temperatures are often required to achieve peak efficiencies, but this new material does not have the above-mentioned limitations on use. These scientists are from the Lawrence Berkeley National Laboratory. The results show that by spraying magnesium metal nanocrystals on a polymer matrix, a soft nanocomposite material is formed. The material can rapidly absorb and release hydrogen at a suitable temperature during the storage and release of hydrogen gas. Magnesium is no longer required for oxidation. Erben, Deputy Director of the Inorganic Nanomaterials Manufacturing Department at Lawrence Berkeley National Laboratory, stated: “The results of this work demonstrate our ability to produce nanoscale composites. The advent of this material subverts the basic principles of thermodynamics and overcomes the Obstacles to movement have truly put an end to the obstacles that are not easily controlled by the atomic combination of materials. The composite material can be widely used in related energy research fields." For this successful study, Earnburn was very excited and proud. “This is a major breakthrough in the history of the design of hydrogen storage materials, batteries and fuel cells. Of course, finding a new type of material that can help find more sustainable energy solutions is the core task of the energy sector, and we Outstanding experiments have successfully completed this task, and at the same time, our success can not be separated from the strong support of the Lawrence Berkeley National Laboratory and the strong cooperation between the partners, as well as to provide us with cutting-edge microscopes, scientific research tools, and scientific research. Collaborators of materials and expertise," he said. Mao, Director of Clean Energy Laboratory at Lawrence Berkeley National Laboratory, also stated: “We have been working closely with the industry to maintain hydrogen storage facilities and develop hydrogen storage performance testing protocols. Erben's team has developed new composite materials that can We are very happy to cooperate and provide them with hydrogen storage research equipment.†It is reported that the research work of Ubern’s scientific team is funded by the U.S. Department of Energy’s Science Office. At the same time, the U.S. Department of Inorganic Nanomaterials Manufacturing is one of the five major nanotechnology research centers of the U.S. Department of Energy, providing researchers with the most advanced nano-manufacturing equipment, nanotechnology, and nanomaterials models, and establishing infrastructure for national nanotechnology research. Investment funds. It is reported that this new nanocomposite material is extracted from a matrix of a methyl acrylate polymer derived from the resin glass. Erben's team used an electron microscope with a minimum resolution of 0.5 angstroms to observe individual magnesium nanocrystals dispersed on a polymer, and used the microscope's high-resolution imaging capability to track defects and hydrogen stored in new composites. Activities to observe. In the end, through spectral investigations, they confirmed the presence of hydrogen in this novel material with unprecedented accuracy.
