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.
From the street into your cellar: A Swiss success story
Each of our batteries has already rendered valuable service for mobility in Switzerland. We use components that have proven themselves in tough everyday use:
The pioneers: We built our first storage systems using batteries from the iconic yellow "Post-Töffli" (mopeds of the Swiss Post). These batteries have reliably delivered letters and parcels over thousands of kilometres.
The powerhouses: Later, we expanded our spectrum to include batteries from public transport (buses) and from municipal vehicles that keep our cities clean.
The milestone: Since spring 2026, we at Modual have succeeded for the first time in using complete battery packs from electric passenger cars (cars) as highly efficient stationary storage systems.
Circular economy: Because our raw materials are precious
The production of batteries requires valuable raw materials such as lithium and cobalt. It would be ecologically irresponsible to dispose of these materials as long as they are still fully functional.
With a second-life storage system, you become part of the circular economy. You ensure that the energy already invested and the raw materials remain in the cycle for as long as possible. This protects the environment, reduces the carbon footprint of your energy supply, and shows respect for our planet's resources.
For us, sustainability does not mean sacrifice,
for us, sustainability means smart reuse.
Swiss precision and its own "brain"
We believe in local quality. That is why our storage systems are manufactured directly in Brunnen, Switzerland. At the heart of it all, however, is our in-house battery management system (BMS):
Tailor-made control: We programmed the software for the BMS ourselves to perfectly master the special requirements of second-life cells.
Maximum safety: The BMS monitors every cell around the clock and ensures optimal and safe operation.
Longevity: Thanks to the intelligent Swiss control system, we guarantee that the second life of your battery is particularly long and efficient.
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
The battery cells account for about 80% of the CO2 emissions of a battery storage system. By reusing already produced battery cells, modular storage solutions have an ecological footprint that is about 60% lower than that of new storage.
Extract new raw materials
For our home storage systems, we exclusively use LFP battery cells. Depending on the original cell manufacturer and supply chain, there are differences. But as a guideline, about 95 kg of raw materials need to be mined to produce 1 kWh of battery cells. Therefore, several tons of raw materials are behind each battery storage system.
Recycling capacities
Humanity has the know-how to reclaim nearly 100% of the raw materials in a battery. Unfortunately, newly mined raw materials are often still cheaper than those from a recycling process. For this reason, there are only limited capacities, and humanity struggles to build additional ones. In 2024, for example, Europe would only have been able to recycle about 10 percent of the electric vehicle batteries that will return to the market in 2030.
Become part of the solution
Use energy that is already there - safely regulated, locally manufactured, and with a story that continues to be written in your home.
