Hydrogen carriers, such as hydrazine (N H ), may facilitate long duration energy storage, a vital component for resilient grids by enabling more renewable energy generation. Lanthanide coordination chemistry with N H as well as efforts to displace N H from the metal coordination sphere to develop an efficient catalytic production cycle were detailed. Modeling the equilibrium of different ligand coordination, it was predicted that strong sigma donor molecules would be required to displace N H . Monitoring competition experiments with nuclear magnetic resonance confirmed that trimethyl phosphine oxide, dimethylformamide, and dimethyl sulfoxide displaced N H in large or small lanthanide complexes.
氢载体，如肼（N₂H₄），可促进长时间的能量存储，这是弹性电网的一个重要组成部分，通过实现更多可再生能源发电来达成。详细介绍了镧系元素与N₂H₄的配位化学以及从金属配位球中取代N₂H₄以开发高效催化生产循环的努力。对不同配体配位的平衡进行建模后预测，需要强σ供体分子来取代N₂H₄。用核磁共振监测竞争实验证实，三甲基氧化膦、二甲基甲酰胺和二甲基亚砜在大或小的镧系配合物中取代了N₂H₄。
