CO2 is a major greenhouse gas that accounts for three-quarters of all global man-made emissions.
Renewable energy such as solar and wind power is one of the main weapons we have in our fight against global warming, but its intermittency is a problem. Because of this, we desperately need a cost-effective energy storage system to manage its ups and downs.
Lithium-ion batteries are often used to store this energy, but a problem arises when it comes to long-duration energy storage (LDES), and there are sustainability and waste disposal issues associated with electrochemical storage.
