12 times More Storage Capacity than Conventional Storage Batteries

A thermal battery with 12 times more storage capacity than conventional batteries (TED: Thermal Energy Device) has appeared in the storage battery market where demand is increasing. TED has been introduced by CCT Energy Storage based in South Australia and is attracting attention as a practical thermal battery.

TED has four distinct features from other storage batteries.
i) TED receives the electricity generated by different ways such as photovoltaic (PV) power generation, wind power generation and fossil fuels, and can convert its energy into thermal energy and store. And the stored thermal energy can be easily converted to the electrical energy. In other words, TED is versatile.
ii) TED is efficient. It can store the energy at more than 12 times the density of lead-acid batteries and 5 to 6 times that of lithium ions.
iii) TED is affordable. It may be economical to store thermal energy from phase change materials (PCM), convert it to electrical energy, then use it when needed.
iv) TED has no negative impact on the environment. Batteries have no harmful chemicals and can be recycled.

TED is used to provide electricity to remote communities, commercial businesses, telecommunications networks, and transportation systems. Manufacture of TED will begin at the Lonsdale plant in South Australia, and the European energy partner, MIBA Group, will manufacture TED and distribute them to Denmark, Sweden and the Netherlands. It is expected that 10 TEDs will be supplied to customers as commercial in 2019 and that production in 2020 will exceed 200 units.

CCT Chief Executive Serge Bondarenko said “TED had the ability to change the global energy market by providing the most affordable and environmentally friendly alternative power source.” TED is an important technology to realize the future of clean energy. We hope that TED, which is likely to be useful as a preparation for natural disasters, will be deployed all over the world.
