The discussion about electric batteries has long been centred around lithium-ion batteries, which use lithium resources in their development. The large-scale rollout of these batteries relies on the development of vast mining projects to source the lithium and other metals and minerals required for their production.
The firm believes that thermal battery technology can complement other forms of energy storage, rather than replace them, to support the green transition. The benefit of using salt is that is widely available and easy to extract. Salt is good at storing heat and does not produce toxic by-products. It is also thought that salt tanks can be recharged thousands of times for a period of up to 40 years, around three times longer than other existing storage solutions.
