High density mechanical energy storage with carbon nanothread bundle [PDF]
Nature Communications, 2020 AbstractThe excellent mechanical properties of carbon nanofibers bring promise for energy-related applications. Through in silico studies and continuum elasticity theory, here we show that the ultra-thin carbon nanothreads-based bundles exhibit a high mechanical energy storage density.

Molecular solar thermal energy storage in photoswitch oligomers increases energy densities and storage times [PDF]
Nature Communications, 2018 AbstractMolecular photoswitches can be used for solar thermal energy storage by photoisomerization into high-energy, meta-stable isomers; we present a molecular design strategy leading to photoswitches with high energy densities and long storage times. High measured energy densities of up to 559 kJ kg−1 (155 Wh kg−1), long storage lifetimes up to 48.5 ...

International Journal of Hydrogen Energy, 2018 Thermochemical energy storage based on metal hydrides has gained tremendous interest in concentrated solar power systems (CSP). In such systems, two metal hydride beds are connected and operating in an alternative way as energy storage or hydrogen storage. However, the selection of metal hydrides is essential for a smooth operation of these CSP systems
