Solutions like energy batteries are vital for creating a more resilient, reliable, and sustainable energy infrastructure, supporting the integration of renewable sources and addressing the challenges posed by the variability and intermittency of certain energy generation technologies.
Chicken eggshells can contribute to the evolution of rechargeable battery storage systems, making them more accessible, safe and sustainable.
How can eggshells be the answer to energy batteries systems?
A study by the University of Murdoch developed a mechanism that uses chicken eggshells as electrodes, transporting electricity to power batteries, as they contain a large amount of calcium carbonate. Their chemical makeup transforms into an electrode when cooked and crushed, improving the efficiency of energy transportation.
Lithium-ion batteries, which are used to conserve water-based renewable energies, are expensive, dangerous in the event of a malfunction and use fossil fuels. On the other hand, the reuse of waste such as eggshells is beneficial to the field of renewable energy.
This discovery is significantly relevant, as renewable energy sources are privileged and chicken eggshells are a possible solution for a greener world, where sustainability is prized.
Eggshells contain a variety of active chemical substances that can be used in the following ways
The areas of food processing and manufacturing, nutrition, the pharmaceutical industry and even the family sphere are where hen’s eggs are used in large proportions. However, the shells are transferred to landfills as solid waste.

Electrodes can be adjusted to improve their performance by adding suitable additives, such as biodegradable redox polymers, titanium boride/sulfide (TiB2, TiS2) or bismuth oxide compounds (Bi2O3).
In addition, the study shows that aqueous lithium and sodium electrolytes, which are highly conductive and have varying salt concentrations, could be a viable alternative to the non-rechargeable primary energy batteries currently in use.
In short, there is an urgent need to change from a linear economy to a circular one, where waste is reduced, reused and recycled, enhancing sustainable development by focusing on waste management.

Our efforts in energy storage
For many years, Universal Kraft has been experimenting with compressed air storage systems, integrating the production of renewable energy from solar or wind power with a compressed air energy storage system stored in tanks or the ground. We are currently working with partners to create a new technology that uses a compressor to pump air into a tank or the ground for storage, and then reverses the process to feed energy into a generator when needed.
