Circular economy in action

A second life for energy

Our energy storage systems give batteries from electromobility a second life. Through reuse, we lower the demand for new raw materials, reduce CO₂ emissions and create products that make it possible to use energy more efficiently and in a more environmentally friendly way.

Your next battery
has a story

Imagine a high-performance athlete ends their career in professional sports. They might no longer be fast enough for the world elite, but they are still fitter and have more stamina than average. It's the same in the world of electromobility: Batteries from electric vehicles are replaced after a few years, even though they still have an enormous capacity of 80%.

This is where our second-life batteries come into play. Instead of wasting valuable resources, we give these powerhouses a new, meaningful purpose – as stationary battery storage in your home.

Self-consumption optimization for PV systems

Why give away solar power when you can use it yourself?

Get more out of your own energy right away. Without storage, a building often only uses about 30% of its own PV production – the rest is fed into the grid at low tariffs. With a well-dimensioned storage system, you can use over 70% of your solar power yourself.

E-Mobility & Load Management

The foundation for any EV infrastructure. Our dynamic load management prevents expensive peak loads, protects the grid connection, and ensures (if desired) solar-optimized charging.

RCP & vRCP Communities

Energy communities made easy. modual ensures precise measurement, control and data-based billing for ZEV (association for self-consumption) and VZEV (virtual ZEV) – fair, transparent and compliant with the law.

Your contribution to the circular economy

By using a battery storage system, you generally reduce your ecological footprint. By purchasing a Second Life battery storage system, you additionally reduce CO2 emissions during storage production, prevent the mining of new raw materials, and give society time to build up our recycling capacities.

CO2

CO2-Reduktion wissenschaftlich belegt.

Batteriezellen verursachen den Grossteil der Emissionen eines Speichers. Durch die Weiternutzung bestehender Fahrzeugbatterien vermeidet modual die aufwendige Neuproduktion von Zellen:

Serie Basic: 62% weniger CO2 in der Herstellungs- und 2nd-Life-Phase gegenüber der Neuproduktion eines herkömmlichen Heimspeichers (entspricht einer Gesamtersparnis von 33% über den gesamten Batterie-Lebenszyklus bzw. 2’827 kg CO2e).

Serie Pro: >80% CO2-Vermeidung in der 2nd-Life-Phase (Konservativ geschätzt. Die zusätzliche Reduktion wird durch gezielte Materialeinsparungen am Gehäuse erreicht; die offizielle Validierung der Daten folgt).

Neue Rohstoffe schürfen

Für unsere Heimspeicher verwenden wir exklusiv LFP-Batteriezellen. Je nach ursprünglichem Zellhersteller und Lieferkette gibt es Unterschiede.

Aber als Richtwert müssen ca. 95kg Rohstoffe gefördert werden, um 1kWh Batteriezellen herzustellen.

Hinter jedem Batteriespeicher stehen also mehrere Tonnen Rohstoffe.

Recycling-Kapazitäten

Die Menschheit besitzt das Know-how, um nahezu 100% der Rohstoffe in einer Batterie zurückzugewinnen.

Leider sind neu geschürfte Rohstoffe oft noch billiger, als welche aus einem Recycling-Prozess. Aus diesem Grund gibt es nur limitierte Kapazitäten und die Menschheit tut sich schwer zusätzliche aufzubauen.

Im 2024 hätte man in Europa z.B. nur ca. 10 Prozent der Elektrofahrzeug-Batterien recyceln können, die im Jahr 2030 aus dem Markt zurückkommen werden.

Unsere Umweltbilanz wurde von der Stiftung myclimate in einer umfassenden Studie (LCA) berechnet und durch die Umweltberatung Carbotech nach den strengen ISO-Normen 14040 und 14044 unabhängig geprüft und bestätigt.
