6 FAQs about [Energy storage and electrolysis of aluminum to produce hydrogen]

What is the energy requirement for aluminum-based hydrogen production?

According to a life cycle assessment (LCA) conducted by Hiraki et al. considering both the processes of the required deionized water production and residue treatment, the energy requirement of aluminum-based hydrogen production is only 2% and its carbon dioxide emission is 4% of conventional production methods.

Can aluminum be used as a source of hydrogen?

MIT researchers have developed practical guidelines for generating hydrogen using scrap aluminum and water. When combined with water, aluminum can provide a high-energy-density, easily transportable, flexible source of hydrogen to serve as a carbon-free replacement for fossil fuels.

How can you produce hydrogen from aluminum?

Reacting aluminum with water at room temperature produces hydrogen. The reaction also forms aluminum hydroxide.

Does aluminum compete with hydrogen based electrolyzers?

Nonetheless, the proposed approach based on aluminum appears to compete with P2P systems based on hydrogen implementing low and high temperature electrolyzers, especially in terms of storage needs (23.5 kWh L −1 volumetric energy density) and safety (aluminum, e.g., as ingots, is neither toxic nor dangerous when stored).

Why is aluminum useful for hydrogen production?

Aluminum and its alloys are rather useful for hydrogen production. The high activity of aluminum makes it able to extract hydrogen from different sources including water and hydrocarbons.

How does aluminum hydroxide react with water?

In the vicinity of room temperature, the reaction between aluminum metal and water to form aluminum hydroxide and hydrogen is the following: 2Al + 6H2O = 2Al(OH)3 + 3H2. The gravimetric hydrogen capacity from this reaction is 3.7 wt.% and the volumetric hydrogen capacity is 46 g H2/L.
