Round-trip efficiency
TheStorage converts renewable energy into heat, stores it in sand, and delivers it as industrial steam on demand. It helps you to optimize your heat processes and allows you to utilize low-cost electricity periods in the most cost-efficient way. It is great in serving both needs and continuous non-interruptive processes.
Because the charger, storage, and heat exchanger are independent units, we can configure the best combination to suit your process and economics. These are the ranges we build.
We deliver all temperatures and pressures used in process steam.

Applications
TheStorage Thermal Energy Storage integrates with existing production systems to deliver clean steam across multiple industries.
Steam
Steam is the primary source of process heat in food and beverage production. It is used for cooking, pasteurization, evaporation, and drying at temperatures typically between 100°C and 200°C. This range also fits well with what TheStorage's thermal energy storage can deliver.

Steam
Precast and aerated concrete gain their strength from heat. Atmospheric steam curing runs at 40 °C to 100 °C, while autoclaved aerated concrete needs saturated steam at 160 °C to 190 °C. Both are batch cycles with sharp, repeated peaks in demand — exactly the pattern a thermal store is built to absorb.

Hot Oil
Chemical production needs precise, uninterrupted heat across a wide band — reactor and jacket heating, distillation, evaporation, drying and calcination. TheStorage delivers steam up to 550 °C and thermal oil up to 350 °C from the same store, holding setpoints steady while decoupling your heat supply from fuel markets.

Steam
Hot Oil
Polymer processing runs on tightly controlled heat. Extrusion and compounding sit between 160 °C and 300 °C, and the thermal oil loops that serve presses, dies, rolls and curing ovens operate up to 350 °C. Stored renewable heat replaces fired heaters and gas without changing the line.

Steam
Pharmaceutical plants run on clean utilities. Sterilisation-in-place uses saturated steam above 121 °C at around 2 bar, and the same steam heats the water for clean-in-place cycles and the air for drying. All of it has to be available on demand, every shift, without interruption.

Hot Oil
Around 80 % of industrial heat still comes from burning fossil fuels, and much of that duty is served by steam or thermal oil. If your process needs steam up to 550 °C or hot oil up to 350 °C — textiles, minerals, ingredients, laundries, district heat — TheStorage is likely a fit.
