As energy storage and home battery schemes dominate headlines internationally, thermal energy continues to be a silent achiever.

Perhaps one of the oldest technologies known to mankind, thermal energy dates back to the cavemen when ‘hot rocks’ would be used to heat food and water.

It’s a relatively simple concept but the benefits are significant.

So how does thermal energy storage work?

All substances hold an amount of heat energy. When a solid is heated to the point of phase change, when it becomes a liquid or a gas, the energy generated from this change is able to be stored.

CCT’s Thermal Energy Device (TED) uses a unique phase change material that can store energy at more than 12 times the density of a lead acid battery. The stored energy can then be extracted from the battery via a thermic generator to provide electricity when needed.

The benefits of thermal energy storage include affordability, versatility and minimal environmental impact.

•         Affordability

We need electricity 24 hours a day – not just when the sun is shining and the wind is blowing.

TED’s ability to store latent heat from an inexpensive phase change material and convert it to usable energy – to be used when and where it is needed – is extremely economical.

For a small initial outlay, TED can provide clean energy on demand, significantly reducing electricity charges and even powering entire communities for little or no-cost.

The longevity of TED provides the peace of mind that it will pay for itself in energy savings for its users within as little as a year (depending on application).

•         Versatility

TED is not only suitable for renewable energy such as wind and solar, it is adaptable to non-renewable energy sources from fossil fuels, biofuels and grid supply.

What’s more, TED can accept any electrical input and convert that energy to heat – making it versatile and long-lasting.

•         Environmental impact

Storing energy has many environmental benefits that can help businesses achieve their sustainability goals by improving efficiency within the power grid.

On a local level, storage systems like TED have no emissions and can be placed anywhere with no immediate environmental impacts.

TED is totally recyclable with no element hazardous to the environment.

Energy is a resource that should be accessible to everyone by remaining cost effective, environmentally safe and sustainable. That’s why TED has a key role to play.
