6 FAQs about [Hydrogen energy storage fuel cell capacity]
Why do we need hydrogen energy storage?
Solar and wind power intermittency and demand non-coincidence require storage. Hydrogen energy storage is one of the only options with sufficient storage capacity. Hydrogen can provide seasonal storage, zero emissions fuel and chemical feedstock. Gas grid can evolve, store and distribute increasing hydrogen amounts at low cost.
How many miles can hydrogen be stored in a car?
Initiatives such as the Hydrogen and Fuel Cell Technologies Office (HFTO) have focused on onboard hydrogen storage for over 300 miles of driving . Currently, materials such as SSHS and alternative storage methods are being investigated. The International Energy Agency has promoted the use of hydrogen for various applications.
Why is hydrogen a potential energy storage medium?
Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.
What is the target density for hydrogen storage in fuel cell cars?
The DOE has also established comprehensive targets (including a gravimetric density of 2.2 kWh/kg and a volumetric density of 1.7 kWh/L) for onboard hydrogen storage in fuel cell automobiles. These targets serve as benchmarks for achieving specific gravimetric and volumetric densities as well as system costs , , .
How can hydrogen storage capacity be enhanced?
Hydrogen storage capacity can be enhanced through doping, functionalization, hybridization, and nanostructuring. MOFs are ideal for fuel cells because of their high porosity and surface area, which allow them to adsorb hydrogen via weak van der Waals forces.
Can hydrogen provide fuel for a fuel cell system?
Alternatively, and possibly most efficiently, hydrogen can provide the fuel for a fuel cell system. For a future energy economy based on hydrogen, this offers one of the most promising solutions with 60% efficiency achievable in a simple fuel cell and perhaps 70%–75% with a hybrid system.
