“…of Energy has started a new methane storage program [4] with the following targets: 0.5 g (CH 4 ) per g (sorbent) for gravimetric capacity and r = 0.188 g/cc (11.741 mmol/cc) for volumetric capacity, which corresponds to the density of compressed natural gas (CNG) at 250 bar and 298 K. The new volumetric target is equal to 263 cc (STP: 273.15 K, 1 atm) per cc, which is significantly higher than the previous target of 180 cc (STP) per cc at 35 bar [5]. So far, methane is typically compressed in a pressure containment vessel at ca.…”

Abstract.A comparison synthetic strategy of Metal-Organic Frameworks, namely, Hongkong University of Techhnology-1 {HKUST-1[Cu 3 (BTC)] 2 } (BTC = 1,3,5-benzene-tri-carboxylate) through solvothermal and electrochemical method in ethanol:water (1:1) has been conducted. The obtained material was analyzed using powder X-ray diffraction, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Thermo-Gravimetric Analysis (TGA) and Surface Area Analysis (SAA). While the voltage in the electrochemical method are varied, ranging from 12 to 15 Volt. The results show that at 15 V the texture of the material has the best degree of crystallinity and comparable with solvothermal product. This indicated from XRD data and supported by the SEM image to view the morphology. The thermal stability of the synthesized compounds is up to 320 °C. The shape of the nitrogen sorption isotherm of the compound corresponds to type I of the IUPAC adsorption isotherm classification for microporous materials with BET surface area of 629.2 and 324.3 m²/g (for solvothermal and electrochemical product respectively) and promising for gas storage application. Herein, the methane storage capacities of these compounds are also tested.

“…However, how to use it in a safe and economical way is still a hot topic nowadays. The US Department of Energy (DOE) volumetric storage target for methane is 180 v/v at 35 bar and 298 K. 50 Physisorption of methane onto a support can in principle provide an effective approach for storage with energy densities comparable to compressed gas at much lower pressures. We measured the CH 4 uptake for the two carbazole based networks up to 1.1 bar, as shown in Fig.…”

Two novel conjugated microporous networks, P-1 and P-2, with carbazole-spacer-carbazole topological model structures, were designed and prepared by FeCl 3 oxidative coupling polymerization. Monomer m-1 (fluorenone spacer) was modified with a thiophene Grignard to form the fluorenyl tertiary alcohol monomer m-2, and this step can increase the polymerization branches from four to five and incorporate the polar -OH group into the building block. N 2 adsorption isotherms show that, after modification, the Brunauer-Emmett-Teller (BET) surface area of P-2 (1222 m 2 g À1) is two times that of P-1 (611 m 2 gand the total pore volume increases 1.63 times from 0.95 to 1.55 at P/P 0 ¼ 0.99. However, the domain pore size (centred at 1.19 nm) and the pore distribution of both networks are not changed. It demonstrates that the domain pore width may be determined by the size of the rigid carbazole-spacercarbazole backbone, not the degree of crosslinking when the networks were prepared under same polymerization conditions in this system. Hydrogen physisorption isotherms of P-1 and P-2 show that the H 2 storage can be up to 1.05 wt% and 1.66 wt% at 77 K and 1.1 bar, and the isosteric heat is 9.89 kJ mol À1 and 10.86 kJ mol À1 , respectively. At 273 K and 1.1 bar, the CO 2 uptake capacity of P-2 can be up to 14.5 wt% which is 1.63 times that of P-1 under the same conditions. The H 2 and CO 2 uptake capacities of P-2 are among the highest reported for conjugated microporous networks under similar conditions. The CO 2 /CH 4 and CO 2 /N 2 selectivity results indicate that P-1 exhibits a slightly higher separation ability than P-2. There is often a trade-off between absolute uptake and selectivity in other microporous organic polymers. Fine design and tailoring the topological structure of the monomer can change the adsorption isosteric enthalpy and optimize the gas uptake performance. The obtained networks with the carbazole-spacer-carbazole rigid backbone show promise for potential use in clean energy applications and the environmental field.

“…A recent discovery, monolithic, microporous carbon fiber composite material for storage of natural gas by relatively low-pressure adsorption, may enable extensive use of natural gas in transportation. 9 The objective of the gas storage project (part of the OHVT Systems Technology Program) is to develop a monolithic, adsorbent, carbon material capable of storing greater than 180 V/V of natural gas at 3.5 MPa and ambient temperature. Retentivity, the tendency of activated carbon to retain adsorbed gases, will be minimized using a novel electrical desorption technique.…”

The Heavy Vehicle Propulsion Materials Program was begun in 1997 to support the enabling materials needs of the DOE Office of Heavy Vehicle Technologies (OHVT). The technical agenda for the program grew out of the technology roadmap for the OHVT and includes efforts in materials for: fuel systems, exhaust aftertreatment, valve train, air handling, structural components, electrochemical propulsion, natural gas storage, and thermal management. A five-year program plan was written in early 2000, following a stakeholders workshop. The technical issues and planned and ongoing projects are discussed. Brief summaries of several technical highlights are given.
