We have long had the technology and opportunities for successfully making renewable energy a reality – worldwide and economically. A huge milestone on the way are high-temperature steel storage elements. They allow us to leverage the full potential of wind and solar energy sources, and thus let big visions of sustainable energy finally come true. Without carbon emissions. For generations to come.


Everyone is talking about renewable electricity. But we need more than half of our energy as heat. Most of which is won by burning gas and coal, which creates a large share of the world’s carbon emissions. With Menion, we store fluctuating wind and solar energy as high-temperature heat. This means, in addition to industrial process heating, we also deliver local and district heating in a flexible and reliable way. Carbon emissions are eliminated – and added value remains in the regions.


Menion stores energy as thermal power – at 650°C in steel elements. This can then be used as process, local or district heating at any time. For larger facilities (from 5 MWh), a steam turbine can be used which also delivers electricity on a schedule from the stored heat. Carbon-free, revolutionarily affordable in its system costs, and with high scalability even at the gigawatt level.


Fossil fuels are what made industrialisation, and thus our modern life, possible. But the time has run out. Wind and solar energy are sustainable, emission-free and, today, more economical to gain than coal, oil or gas. Thanks to new technologies, we can force fossil fuels into retirement. Menion makes an important contribution to achieving this.
Advantage 1

Long-lasting and
stable in value

Menion’s number of cycles is virtually unlimited, the life cycle of the system is far beyond 40 years. The steel, about 40% of the investment, can be fully re-used through recycling.
Advantage 2

Up to 95% effectiveness thanks to cogeneration

The principle of cogeneration, combined power and heat, achieves an effectiveness of up to 95% (25% electric and 70% thermal). The heat can be instantly used for process or district heating. For reconversion, 25% to 35% of the heat is turned into power. The remaining heat, at 80°C to 120°C, can then be fed into the local heating network.
Advantage 3


The size and performance of Menion can be adapted to meet individual needs – all the way to the gigawatt level.
Advantage 4

Affordable and
low maintenance

The LCOS (Levelised Cost of Storage) is between 2 cents/kWh and 4 cents/kWh and may fall even further in the future.
