“…The studies performed at the Savannah River National Laboratory (United States) resulted in the development of the lanthanide borosilicate glass with a PuO 2 content of up to ~9.5 wt % [5,6]. However, detailed investigations with the use of X-ray powder diffraction analysis and electron microscopy revealed that this glass contains residual unreacted plutonium dioxide.…”

The elemental and ionic quantitative analyses of the synthetic lanthanide borosilicate glass (Al-B-Gd-Hf-La-Nd-Pu-Si-Sr-O) are performed using the characteristics of the X-ray photoelectron spectra of the outer-shell and inner-shell electrons in the binding energy range 0-1000 eV. The oxidation states of the metal ions in this glass are determined and correspond to the Al 3+ , La 3+ , Nd 3+ , Gd 3+ , Hf 4+ , Pu 4+ , Si 4+ , and Sr 2+ ions. Taking into account the binding energies of the O 1 s electrons for the glass sample under investigation, the average lengths of metal-oxygen bonds on the surface of the sample are estimated to be 0.191 and 0.176 nm, which correspond to oxygen binding energies of 531.3 and 532,3 eV, respectively.

“…The LNG storage tank is charged slowly (typically in 200 days) and discharged (LNG regasification) rapidly on short notice to meet seasonal natural gas demand, primarily for heating applications . As the U.S. Northeast region has the largest share (85%) of the country’s LNG storage capacity, LH 2 could also potentially provide high value to the region, which requires future studies to explore viability of repurposing the large LNG storage inventory to store LH 2 .…”

Hydrogen can be valuable for deep decarbonization of electricity systems as well as energy end-uses where direct electricity is challenged. While most hydrogen supply chain analyses focus on storing hydrogen as compressed gas hydrogen (CGH 2 ) storage, hydrogen storage systems with lower capital cost of storage capacity such as liquefied hydrogen (LH 2 ) and liquid organic hydrogen carriers (LOHC) may provide a differentiated value for energy system decarbonization. However, the latter systems have disadvantages (e.g., higher capital cost of charge/ discharge capacity, boil-off, high energy requirement for conversion/ reconversion) that could impede their deployment. In this study, we expand upon a previously developed electricity-hydrogen infrastructure planning model, DOLPHyN, to explore the value of liquid hydrogen solutions for energy storage and transport in a deeply decarbonized energy system. First, we show that TOL-LOHC (i.e., toluene-based LOHC) and LH 2 are beneficial as seasonal energy storage systems, while CGH 2 is more suitable for shorter-duration storage (e.g., weekly) cycling. The addition of LH 2 and LOHC enables more efficient utilization of deployed electric generation and power-to-hydrogen generation infrastructures. Second, we show that LH 2 is more favorable than LOHC for providing long-term storage for the power sector because its primary capital costs and energy penalty for conversion are incurred during charging periods, which typically correspond to when renewable energy is more abundant. Cost effectiveness of LH 2 is based on accounting for boil-off rates of largescale LH 2 systems. Third, we show that commercial viability of LOHC is strongly tied to the ability to lower the energetic consumption of the dehydrogenation process as well as its capital cost.
