Technology company creates sustainable storage solutions from used lithium-ion batteries
Wolfurt (Austria), September 18, 2023 – e.battery systems produces sustainable energy storage systems (ESS) for industry and commerce. The battery technology specialist utilizes used lithium-ion batteries from electric and hybrid vehicles of well-known manufacturers for its innovative second-life solutions. The first modular energy storage systems were installed in July. Through automated self-consumption optimization and peak shaving, they enable safe and efficient operation while saving resources. e.battery systems aims to produce a total capacity of 15 megawatt hours in 2023. One gigawatt hour per year is planned for the future.
Easy, efficient and environmentally friendly: The battery technology specialist e.battery systems is contributing to the energy transition with its innovative second-life energy storage systems (ESS). After a development and pilot phase of around 18 months, the technology company, based in Wolfurt (Austria), is now launching its first systems based on lithium-ion batteries from electric and hybrid vehicles. This resource-friendly recycling solution extends the life of batteries by around 10 years as well as reducing costs by 30% and material consumption by 70% in comparison with new systems.
Flexible modular storage solutions
Energy storage systems provide a reliable way to enable autonomous operation using power generated from clean production means such as photovoltaics and wind/hydro power. “Sustainable products are the basis for tomorrow’s circular energy economy. With our modular systems, we offer optimized solutions for a wide range of industrial applications.” — Christopher Schöpf, founder and CEO of e.battery systems. The capacity of the storage systems ranges from 260 kilowatt hours to several megawatt hours. Intelligent charging and discharging management ensures top efficiency.
The storage solution uses 19″ server cabinets that can be flexibly scaled for inside and outside spaces. For outside applications, IP-certified server cabinets are used, or standard server cabinets are installed in 10, 20 and 40-foot containers. The modular solution allows the storage systems to reach capacities of 800 kWh (10-foot), 2 MWh (20-foot) and 4.7 MWh (40-foot). In addition to self-consumption optimization, the systems implement peak shaving and support the charging infrastructure.
“Often, the power grid cannot provide the power required for the public charging infrastructure. Storage systems like ours can help with this. Each system supplies a power of 67.5 kW and can be expanded on a modular basis.” — Project Manager Nikolai Abel. The storage systems also offer protection against power outages and blackouts. In combination with other systems, they are also suitable for 50 Hz grid frequency stabilization and overload management.
Reference projects: Optimization of renewable energy
The 20-foot container module solution at Bischof Lagerhaus AG stores around 1.6 megawatt hours of energy. The subsidiary of Bischof Lebensmittellogistik operates a fully automatic multi-temperature center for the refrigeration of foodstuffs in Sennwald, Switzerland. 10,000 freezer pallet bays, 1,000 multi-temperature bays and 15,000 dry pallet bays guarantee the perfect temperature for the stored goods. Since 2020, a photovoltaics system measuring more than 4,000 square meters on the roof of the building has ensured a sustainable source of refrigeration power. Following expansion in October 2023, more than 1,800 kWp of potential power will be available from a system measuring more than 9,000 square meters. The combination of this facility with the energy storage system of e.battery systems will now enable the optimization of self-consumption. “Every kilowatt counts. We cover most of our demand from solar power, and we’re reducing our CO2 consumption, securing our cold chain and even benefiting financially in the long term.” — Christoph Schruf from Bischof Lagerhaus.
The scalable solutions from e.battery systems can also be used to complement wind and hydro power. A small hydro power plant in Schlins, Vorarlberg, supplies the adjacent industrial park with power. Since July, a custom energy storage system with a capacity of around 260 kilowatt hours has been used to reduce peak loads. The intelligent solution is activated automatically when energy peaks occur and covers the increased power requirement from the battery storage system. “This combined solution reduces our energy costs and allows us to operate autonomously. The easy-to-integrate solution is ideal for countering load peaks and, subsequently, saving on power costs,” says Martina Walch, owner and operator.
