The paper describes the synthesis and characterization (chemical, structural, and thermal) of a new crystal phase of lithium hydrazinidoborane (LiN2H4BH3, LiHB), is a new material with potential for solid-state chemical hydrogen storage.
Turning the “hydrogen economy” concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels. Their report on a new solid, stable material that can pack in a large amount of hydrogen that can be used as a fuel appears in the American Chemical Society journal Chemistry of Materials.
Umit B. Demirci and colleagues explain that storing hydrogen in solids is a recent development and a promising step toward building a hydrogen economy. That’s the idea originated in the 1970s and promoted by former President George W. Bush that we replace fossil fuels with hydrogen, which can serve as a clean fuel. Although a promising alternative to conventional energy sources, hydrogen has posed a number of technological challenges that scientists are still overcoming. One of those issues has to do with storage. Previously, researchers were focused on developing hydrogen-containing liquids or compressing it in gas form. Now, solid storage is showing potential for holding hydrogen in a safe, stable, and efficient way. In the latest development on this front, Demirci’s team looked to a new kind of material.
They figured out a way to make a novel crystal phase of a material containing lithium, boron and the key ingredient, hydrogen. To check how they could get the hydrogen back out of the material, the scientists heated it and found that it released hydrogen easily, quickly, and with only traces of unwanted by-products.
