Are aluminum-based energy storage technologies defensible?

The coming of aluminum-based energy storage technologies is expected in some portable applications and small-power eco-cars. Since energy generation based on aluminum is cleaner than that of fossil fuel, the use of aluminum is defensible within polluted areas, e.g. within megapolises.

What is aluminum based energy storage?

Aluminum-based energy storage can participate as a buffer practically in any electricity generating technology. Today, aluminum electrolyzers are powered mainly by large conventional units such as coal-fired (about 40%), hydro (about 50%) and nuclear (about 5%) power plants , , , .

What is the feasibility study of aluminum based energy storage?

To provide the correct feasibility study the work includes the analysis of aluminum production process: from ore to metal. During this analysis the material and energy balances are considered. Total efficiency of aluminum-based energy storage is evaluated. Aluminum based energy generation technologies are reviewed.

Why is aluminum a strategic energy buffer?

In this field aluminum can play a role of strategic energy buffer. Due to zero self-discharge aluminum is a long term storageable and manoeuvrable fuel, which can be utilized on demand promptly. In future, if inert anodes are developed, aluminum production technology can be also integrated into distributed energy.

Can aluminum be considered a perspective energy carrier?

So, aluminum can be regarded as perspective energy carrier and has a good chance for large-scale integration in global energy storage. To provide the correct feasibility study this work will be started from aluminum production process analysis, which will examine the whole chain: from ore to metal.

What is the calorific value of aluminum based energy storage?

Calorific value of aluminum is about 31 MJ/kg. Only this energy can be usefully utilized within aluminum-fueled power plant. So, it shows the efficiency limit. If 112.8 MJ are deposited, the maximum cycle efficiency of aluminum-based energy storage is as follows: 31 MJ 72.8 MJ = 43 %. This percentage represents the total-thermal efficiency.
