EnergyNest - The Thermal Battery Company

Energy-saving on an industrial scale

Our thermal battery technology is modular, flexible, scalable and built for purpose. The principle of the technology is to store thermal energy within a solid state material. Steel pipes run through a concrete-like material, transferring the heat throughout the storage system, ready for release when required.

Commercially viable and easily deployable

Our systems pay for themselves within 2–5 years, increase profits for decades and reduce our customers’ carbon footprint. Unlike many other energy storage solutions, they can be deployed anywhere and cater to medium and long-duration storage, from 10 MWh to 10 GWh.

Made by experts invested in your success

We have a deep understanding of the changes happening in the energy business and the new demands that are arising. Our team of experienced scientist, engineers and business professionals will work with you to customise a solution, from initial assessment through to commissioning and operation.

Balancing the grid, efficiently

As we move further towards a world of renewables, our thermal battery technology will enable a more responsible use of intermittent energy, helping to balance the power grids and ensure a clean future.

    This is our 1st commercial thermal battery module coming to life. It will be made "only" of steel and the high performance contrete HEATCRETE. This radical new tech will help industrial players, energy companies and/or various types of power plants to use energy more efficiently, effectively (i.e. profits!) and to reduce CO2. Next step... transport to our @Mebin manufacturing site for casting.

    We are the first company to develop an economically viable system for large-scale thermal energy storage. Our energy storage solutions help industrial manufacturers and power plants monetizing their waste heat streams. Currently, process heat is usually generated by burning natural gas – it’s not a climate-friendly process. Just as with burning any fossil fuel, CO2 is emitted. According to PwC, 473 terrawatt hours of process heat are needed every year (2013). Imagine using your own waste heat to supply the process heat you need – on demand! Our thermal energy storage allows you to do just that, with strong benefits for the environment and for business. Edison of Handelsblatt Media Group reports on our technology (German language):

    Discussing the changing energy landscape and its implications with high school students in Lima, Peru Our CEO Dr. Christian Thiel visited Colegio Reina del Mundo, Lima’s German-Peruvian High School, last month to speak about the future of energy systems. During the lively workshop students discussed current energy sources and debated the environmental threats of climate change as well as future opportunities for the environment and society. The students were particularly interested in fossil fuel conservation, renewable energies, the reduction of CO2 and energy storage as a key enabler, and shared ideas on how energy systems could be adjusted to make a positive contribution for future generations.#energy #change
