PURPOSE: A carbon nano-tube-based hydrogen storing media is provided to improve the hydrogen storing capability of carbon nano-tubes by ball-milling the carbon nano-tubes under an extreme low temperature. CONSTITUTION: A carbon nano-tube-based hydrogen storing media is obtained by ball-milling ...
By performing density functional theory calculations we show that the HSF is stable over hydrogen molecule attack and thus qualified for acting as a potential hydrogen storage medium. The interaction between the HSF with hydrogen molecules is found to be essentially via van der Waals force, making ...
Mathis,D.A 摘要: The production of hydrogen as an energy storage medium appears particularly attractive in connection with schemes for the utilization of primary energy sources for which a storage of the provided energy is vital because of the intermittent nature of operation or the remoteness of ...
Hydrogen can be considered an energy storage medium in the same way other chemical fuels store energy (i.e., in the chemical bonds that make up the molecules). At standard temperatures and pressures, hydrogen exists as a gas similar to natural gas (i.e., methane), and can be stored by...
To expand, oil or gas reserves, also referred to as hydrocarbon reservoirs, are geological structures that have gone through different diagenetic processes including formation from a source rock, subsequent movement, and maturation to eventually function as a storage medium for hydrocarbons. Predominantly...
The recent discovery of borospherene Bmarks the onset of a new kind of boron-based nanostructures akin to the Cbuckyball, offering opportunities to explore materials applications of nanoboron. Here we report on the feasibility of Li-decorated Bfor hydrogen storage using the DFT calculations. The...
In this work, using density functional calculations, we systematically investigated the hydrogen storage properties of the two-dimensional (2D) Ti2C phase, which is a representative of the recently synthesized MXene materials (ACS Nano 2012, 6, 1322). As a constituent element of 2D Ti2C phase,...
Dihydrogen (H2), commonly named ‘hydrogen’, is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen ...
One special concern has been to demonstrate, on one hand, how these developments would fit into existing energy supply structures, and, on the other, how they would contribute to further development of the energy system as a whole. With that goal in mind it is nec...
When used as an energy storage medium within an electricity system, hydrogen will generally be burned today in aconventional power plantwhich cannot be brought into service as rapidly as some of the fast-acting storage systems discussed earlier. It should therefore be considered as a system for ...
