6 FAQs about [Sodium hydrogen energy storage for energy storage vehicles]

What is the energy consumption of a sodium hydride-based hydrogen storage system?

In a sodium hydride-based hydrogen storage system, there are four sources of energy consumption: 1) drying the sodium hydroxide, 2) raising the temperature of the system to 980C, 3) regenerating the hydride from the hydroxide, and 4) producing hydrogen from the hydride on-board.

Which hydrogen storage approach is best for pure electric vehicles?

Among the hydrogen storage approaches mentioned above, the development of liquid organic hydrogen carriers or liquid organic hydrides for hydrogen storage is more favorable for the application of pure electric vehicles. 2.2. Energy power systems 2.2.1. Fuel cell systems

What is hydrogen storage technology?

Hydrogen storage technology, in contrast to the above-mentioned batteries, supercapacitors, and flywheels used for short-term power storage, allows for the design of a long-term storage medium using hydrogen as an energy carrier, which reduces the consumption of traditional fossil energy sources .

Can hydrogen be stored on a vehicle?

Hydrogen can be stored on-board a vehicle in the form of plastic-encapsulated sodium hydride (NaH) pellets. When the pellets are cut and immersed in water, hydrogen is produced and released. The exposed NaH surface reacts with water, forming sodium hydroxide (NaOH) as a byproduct.

How much does sodium hydride storage cost?

The cost for a sodium hydride storage system is $4.76/kg (including profit from sale of NaOH). This narrows the gap on the overall cost compared to compressed hydrogen ($2.3/kg) and liquid hydrogen ($3.3/kg).

Is sodium hydride energy efficient?

Sodium hydride-based hydrogen storage systems do not require heat integration with the on-board power system, as they release hydrogen directly. However, because the heat generated onboard is lost, the sodium hydride system is inherently less energy-efficient.
