In terms of cost, the primary limiting factors for mono HKUST-1 production include the starting materials’ cost, high solvent usage, and centrifuge cycling times. − Solvent reduction and recovery combined can massively reduce mono HKUST-1 production costs (Figure S50). Additionally, by employing liquid-assisted grinding, it is possible to significantly reduce mixing times by using prepared nanocrystalline powders to form high-density mono HKUST-1 materials while maintaining monolith quality (Figure S49).…”

We are currently witnessing the dawn of hydrogen (H 2 ) economy, where H 2 will soon become a primary fuel for heating, transportation, and longdistance and long-term energy storage. Among diverse possibilities, H 2 can be stored as a pressurized gas, a cryogenic liquid, or a solid fuel via adsorption onto porous materials. Metal−organic frameworks (MOFs) have emerged as adsorbent materials with the highest theoretical H 2 storage densities on both a volumetric and gravimetric basis. However, a critical bottleneck for the use of H 2 as a transportation fuel has been the lack of densification methods capable of shaping MOFs into practical formulations while maintaining their adsorptive performance. Here, we report a high-throughput screening and deep analysis of a database of MOFs to find optimal materials, followed by the synthesis, characterization, and performance evaluation of an optimal monolithic MOF ( mono MOF) for H 2 storage. After densification, this mono MOF stores 46 g L −1 H 2 at 50 bar and 77 K and delivers 41 and 42 g L −1 H 2 at operating pressures of 25 and 50 bar, respectively, when deployed in a combined temperature− pressure (25−50 bar/77 K → 5 bar/160 K) swing gas delivery system. This performance represents up to an 80% reduction in the operating pressure requirements for delivering H 2 gas when compared with benchmark materials and an 83% reduction compared to compressed H 2 gas. Our findings represent a substantial step forward in the application of high-density materials for volumetric H 2 storage applications.

“…As gleaned from research on hydrogen carriers, there are a number of properties to consider when selecting a storage material. 17 These include technical and nontechnical properties such as safety, toxicity, compatibility with existing infrastructure, cost, availability, storage duration, storage capacity, reversibility, durability/cyclability, energy efficiency, and life cycle impacts. As many of the materials evaluated in this analysis have yet to be properly explored for CO2 storage and transport, there are a number of data gaps limiting the ability to estimate these properties.…”

Finding means of storing and transporting captured carbon dioxide (CO2) has become increasingly important. Not all capture technologies (sources) can be co-located with sequestration options (sinks), and the development of an expansive CO2 pipeline network to connect sources and sinks requires significant time and capital. Additionally, temporary storage of CO2 in a solid or liquid state could prove useful for allowing today’s capture technologies to come online before permanent and ideally lucrative CO2 sequestration options open up. There are several methods for reversible solid-state and chemical CO2 storage, but their advantages and limitations have yet to be reviewed. This article focuses on the physical and chemical aspects of CO2 storage via liquid and solid chemical carriers and sorbents, and gives an overview of the energetics around their use, as well as prospects for their future development. Exciting opportunities for co-transporting hydrogen with CO2, for energy efficient long-distance transportation, and for coupling capture and multi-year storage could open up new options for carbon supply chains. Key findings of the analysis are the remarkable storage capacity of oxalic acid and formic acid (CO2-density of 1857 kg/m3 and 1152 kg/m3, compared with condensed liquid CO2 at 993–1096 kg/m3, respectively), the relative scalability and compatibility of carbonate salts for stationary storage with direct air capture, and the potential promise of multiple carriers for CO2 transportation. Solid sorbents do not achieve such ultra-high storage capacities, but could improve storage over compressed gas tanks on a capacity and energetics basis.
