“…Since they work under high pressures, a failure of pressure vessel can be very dangerous, causing gas leaks, fires, and even explosions. To answer this problem and increase performances of high-pressure hydrogen storage tanks, a multi-layered pressure vessel design was proposed featuring the dynamic wall capable of absorbing hydrogen [2,3].…”

“…Adsorbed Natural Gas (ANG) became competitive to the CNG method because of the high energy density capability achievements [5][6][7]. ANG storage tanks use activated carbon as an adsorbent and can achieve storage densities as high as 24 Ib/ft 3 (384 kg/m 3 ) at 500 psia [8]. The disadvantage of ANG storage comes from the heat generated during the adsorption process.…”

The development of adsorptive natural gas storage tanks for vehicles requires the synthesis of many technologies. The design for an effective Adsorbed Natural Gas (ANG) tank requires that the tank be filled isothermally within a five-minute charge time. The heat generated within the activated carbon is on the order of 150 MJ/m 3 of storage volume. The tank can be effectively buffered using Phase Change Material (PCM) to absorb the heat. The effective design of these tanks requires knowledge of the thermal properties of activated carbon with adsorbed methane. This paper discusses experimental measurements of the thermal conductivity of activated carbon with adsorbed methane. It was found that within the tank the thermal conductivity remains almost constant within the temperature and pressure ranges that ANG tanks will operate.

Investigating the Impact of Economic Uncertainty on Optimal Sizing of Grid-Independent Hybrid Renewable Energy Systems

et al. 2021

One of the many barriers to decarbonization and decentralization of the energy sector in developing countries is the economic uncertainty. As such, this study scrutinizes economics of three grid-independent hybrid renewable-based systems proposed to co-generate electricity and heat for a small-scale load. Accordingly, the under-study systems are simulated and optimized with the aid of HOMER Pro software. Here, a 20-year average value of discount and inflation rates is deemed a benchmark case. The techno-economic-environmental and reliability results suggest a standalone solar/wind/electrolyzer/hydrogen-based fuel cell integrated with a hydrogen-based boiler system is the best alternative. Moreover, to ascertain the impact of economic uncertainty on optimal unit sizing of the nominated model, the fluctuations of the nominal discount rate and inflation, respectively, constitute within the range of 15–20% and 10–26%. The findings of economic uncertainty analysis imply that total net present cost (TNPC) fluctuates around the benchmark value symmetrically between $478,704 and $814,905. Levelized energy cost varies from an amount 69% less than the benchmark value up to two-fold of that. Furthermore, photovoltaic (PV) optimal size starts from a value 23% less than the benchmark case and rises up to 55% more. The corresponding figures for wind turbine (WT) are, respectively, 21% and 29%. Eventually, several practical policies are introduced to cope with economic uncertainty.

“…Hydrogen storage is one of the main challenges in the realization of “The Hydrogen Economy”. During the last two decades, many groups have been dedicated to developing a high-efficiency hydrogen storage method both in experiments and theory, including high pressure hydrogen storage tank, , liquid hydrogen, , metal hydrides, complex hydrides, , porous solid materials, − and carbon-based nanostructures. − However, none has been shown experimentally to realize a hydrogen economy; a number of scientific and technical issues still remain. The storage of hydrogen has been identified as a central concern, especially in the on-board application to automobiles.…”

Multiscale Study of Hydrogen Adsorption, Diffusion, and Desorption on Li-Doped Phthalocyanine Covalent Organic Frameworks

et al. 2012

In this paper, we performed a multiscale study on the hydrogen storage capacity of Li-doped phthalocyanine covalent organic frameworks (Li-doped Pc-PBBA COF). We combine the first-principles studies of hydrogen adsorption and migration energies with the kinetic Monte Carlo simulations of hydrogen adsorption, diffusion, and desorption processes in Li-doped Pc-PBBA COF. The first-principles calculations revealed that the Li atoms can be doped on the surface of the channel of Pc-PBBA COF with a binding energy of 1.08 eV. Each Li cation can bind three H2 molecules with an average adsorption energy of 0.11 eV. At most, 24 H2 molecules can be adsorbed in one formula unit, corresponding to a maximum of gravimetric density of 5.3 wt % and volumetric uptake of 45.2 g/L. The diffusion barriers of H2 between different Li-adsorption sites are in the range 0.027–0.053 eV. The KMC simulations have predicted that the optimum conditions of hydrogen storage for Li-doped Pc-PBBA COF are at T = 250 K and P = 100 bar, with a gravimetric density of 4.70 wt % and volumetric uptake of 40.23 g/L. At T = 300 K and P = 1 bar, the adsorbed H2 molecules have fast desorption kinetics, and 97% hydrogen can be released from the adsorbed phase to the gas phase. A two-step modification method (the B-substitution is first) was also advanced to suppress the Li clustering behavior and further improve the binding energy of H2 molecules to doped Li atoms.
