Do you want to replace the fossil fuel consumption of your manufacturing business with inexpensive CO2-free energy?

More and more companies and consumers are paying attention to the environmental impact of the goods and services they buy. A Lumenion high temperature storage system significantly reduces your carbon footprint and increases the attractiveness and competitiveness of your products. Become independent from the increasing costs of fossil fuels by investing in an eco-friendly, long-term solution that keeps your energy prices low.

Do you want to prepare your combined heat and power station for the CO2-free age?

Lowering CO2 emissions is the task of our time, especially for local energy providers. With a high-temperature storage system from Lumenion for your CHP power plant, you can help both existing and new customers meet CO2 targets and satisfy regulatory requirements. Reduce your investment risk significantly by investing in a tried, tested and robust renewable energy storage solution.

Are you a project developer who wants to realize new wind and PV farms?

Increase public acceptance and administrative approval of your project by providing clean, inexpensive heat to surrounding industries and communities. With our Menion high temperature storage system, local residents and businesses can profit directly from nearby wind and PV farms. In addition, you can increase your plant's profitability by saving at peak times and using your stored energy during off-peak hours.

Is your company doing business in a region dominated by coal and steel, and needs to prepare for the post-carbon age?

We support your entrepreneurial spirit by helping you take full advantage of renewable energy opportunities. With our high temperature storage system you can make the most of existing legacy infrastructure in your area, successfully transform your company, and lead your region into a future free of fossil fuels.



    • With Vattenfall Energy Solutions and Gewobag, a housing society, we are piloting a steel-based district storage system in the disused heating station of a large apartment block in Berlin. The sector-coupling steel storage system will absorb regional generation peaks from wind and solar energy and later provide renewable energy as heat and electricity. This project aims to show how well our steel-storage technology is suited to effectively store large amounts of wind and solar energy.
    • With this pilot project we want to demonstrate in a very practical way the special technical and economic suitability of thermal storage systems for the effective use of large amounts of wind and solar energy.
    • Storage capacity: 2.4 MWh
    • Implementation period: April 2018 to October 2020
    • This project is co-financed by the European Regional Development Fund [ERDF].


  • Since 2018 we have been testing our steel storage systems under real conditions in the grid simulation laboratory of the University of Applied Sciences (HTW). In particular, we are testing the fast charging of the steel storage with high power current – as it would occur at times of high solar and wind power peaks.
  • Storage capacity: 450 kWh
  • Implementation period: April 2018 to October 2020
  • This project is co-financed by the European Regional Development Fund [ERDF].



  • Example: Processing plant for organic frozen vegetables with a production capacity of 10 tons per hour.
  • The plant is operated in a highly efficiently and CO2-neutral way.
  • Wind turbines within close geographical reach can be connected directly to the storage system.
  • Our solution: 50 MWh Lumenion-high temperature storage system + steam turbine + electrolizer.


  • Example: Refinery in Northern Germany with wind turbines in close proximity
  • 5 GWh Lumenion-high temperature storage system
  • 100 MW discharging power (thermal)
  • Charging power of 500 MW
