Our first commercial thermal battery is in production. It will be made „only“ of steel and the high-performance contrete Heatcrete®. This radical new technology helps industrial players, energy companies and various types of power plants to operate more energy-efficiently, more effectively (i.e. profits!) and to reduce CO2. Next, it will be transported to our Mebin manufacturing site in Europoort, Port of Rotterdam, for casting.

This view shows 63 thermal elements inside our TO6-7×9 steel cassette. Made of carbon steel piping, that works under pressure, and spirowound steel casing, they’re designed to be used with thermal oil as Heat Transfer Fluid (HTF). You can also see the spacers inside the spirowound casing, grabbing the piping, and ensuring that the piping remains in the right position during the next steps to follow: transport, casting and construction.
EnergyNest is working to make large-scale thermal energy storage globally viable. Its thermal battery enables power producers and energy-intensive industries to utilise excess heat in a flexible manner.
Das Start-up EnergyNest hat einen Wärmespeicher aus Beton entwickelt. Der kann beispielsweise Prozesswärme aus Kraftwerken und Industrieunternehmen lagern.
Our CEO Dr Christian Thiel recently visited Colegio Reina del Mundo, Lima’s German-Peruvian High School, 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.

Wärme in Beton zu speichern ist insbesondere im Neubau durch Nutzung der Gebäudehülle ein erprobtes Mittel. Doch auch hochgradige Prozesswärme kann man so speichern. Nötig ist hier ein Spezialbeton.
EnergyNest has launched a new hub for manufacturing their thermal battery technology at Europoort in Rotterdam. The cleantech company is responding to Europe’s growing demand for flexible and scalable energy storage solutions. Establishing mass-manufacture capability for their battery modules will allow the company’s energy storage projects to be real- ised more quickly and cost-competitively. In collaboration with HeidelbergCe- ment and Mebin, EnergyNest will start its first run in the third quarter of 2018. Manufacturing for two commercial projects will commence at the end of the year.
Norska EnergyNest har lanserat ett nytt nav för tillverkning av företagets termiska batteriteknik på Europoort i Rotterdam. Tillverkningen av nya batterimoduler börjar vid slutet av året vid Mebin RMC-fabrik i Rotterdam, enlig ett pressmeddelande från EnergyNest.
Together with HeidelbergCement, we have launched a manufacturing hub for supplying our thermal battery to the European market. Located strategically in Europoort, Port of Rotterdam, the site will produce the ready-to-use battery modules at a fully automated RMC plant operated and owned by Mebin.
Pre-fabricated module cassettes are cast with Heatcrete®, cured and quality controlled, before being transported directly to project sites for final assembly. The structure provides a consolidated platform for facilitating higher volume output and securing all quality aspects to accommodate the widely expected market growth for energy storage solutions for years to come.
Our VP Supply Chain Jon E. Bergan states that “the manufacturing setup we have established with our partners HeidelbergCement and Mebin is a critical step for the successful roll-out of this important technology, and consequently, contributing to improved energy usage and reducing carbon emissions in the European industrial landscape at a much faster rate”.
Volker Klapperich, Product Manager Civil Engineering at HeidelbergCement, says “expanding our footprint into this green, high potential market is an exciting new opportunity for the HeidelbergCement group”.
Upon invitation by the Wirtschaftsrat der CDU e.V. our CEO Dr Christian Thiel joined 50 selected energy experts at Energy Lab 2030 to develop ideas for the energy system of the future.
