Only metals can store energy

Can metals be used as energy storage media?

In addition, the stored metal could be integrated in district heating and cooling, using, e.g., water–ammonia heat pumps. Finally, other abundant reactive metals such as magnesium, zinc, and even sodium could be exploited as energy storage media and carriers as alternative to hydrogen and other liquid or gaseous fuels.

Can aluminum be used as energy storage?

Extremely important is also the exploitation of aluminum as energy storage and carrier medium directly in primary batteries, which would result in even higher energy efficiencies. In addition, the stored metal could be integrated in district heating and cooling, using, e.g., water–ammonia heat pumps.

Can reactive metals be used as energy storage media?

Finally, other abundant reactive metals such as magnesium, zinc, and even sodium could be exploited as energy storage media and carriers as alternative to hydrogen and other liquid or gaseous fuels. Open-access funding enabled and organized by Projekt DEAL. The authors declare no conflict of interest.

Can aluminum be used as energy storage and carrier medium?

To this regard, this study focuses on the use of aluminum as energy storage and carrier medium, offering high volumetric energy density (23.5 kWh L −1), ease to transport and stock (e.g., as ingots), and is neither toxic nor dangerous when stored. In addition, mature production and recycling technologies exist for aluminum.

Is hydrogen a good energy storage media?

Hydrogen is one of the most promising energy storage and carrier media featuring a very high gravimetric energy density, but a rather low volumetric energy density.

Could unheralded metal be a key part of the renewables Revolution?

The metal is extracted from brightly coloured ore. - Image Credit: Cagla Acikgoz via Shutterstock / HDR tune by Universal-Sci An unheralded metal could become a crucial part of the renewables revolution. Vanadium is used in new batteries which can store large amounts of energy almost indefinitely, perfect for remote wind or solar farms.
