U S Hydrogen Fuel Energy Storage System

How much hydrogen can be stored in a fuel cell vehicle?

Table 1. Technical System Targets: Onboard Hydrogen Storage for Light-Duty Fuel Cell Vehicles a (updated May 2017) For a normalized comparison of system performance to the targets, a usable H2 storage capacity of 5.6 kg H2 should be used at the lower heating value of hydrogen (33.3 kWh/kg H2).

What is hydrogen storage?

Hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell technologies in applications including stationary power, portable power, and transportation.

What is an onboard hydrogen storage system?

As noted above, the onboard hydrogen storage system includes every component required to safely accept hydrogen from the delivery infrastructure, store it onboard, and release conditioned hydrogen to the fuel cell system. U.S. DRIVE performed extensive modeling to evaluate the targets for advanced vehicle technologies, including FCEVs.

What is the DOE hydrogen program?

The DOE Hydrogen Program activities for hydrogen storage are focused on advanced storage of hydrogen (or its precursors) on vehicles or within the distribution system. Hydrogen storage is a key technological barrier to the development and widespread use of fuel cell power technologies in transportation, stationary, and portable applications.

How much energy does a hydrogen storage tank hold?

For example, if a storage tank is rated as holding 5.6 kg usable hydrogen, the total amount of energy in the rated tank would be 5.6 kg multiplied by (33.3 kWh/kg) or approximately 186.5 kWh. For the target to be achieved, at least 90% of 186.5 kWh or 168 kWh needs to be delivered to the fuel cell system.

How much does a hydrogen storage system cost?

Specific system targets include the following: $10/kWh ($333/kg stored hydrogen capacity). The collaborative Hydrogen Storage Engineering Center of Excellence conducts analysis activities to determine the current status of materials-based storage system technologies.
