Used car batteries as energy storage: Munich-based start-up STABL Energy GmbH receives 15 million euros in funding to establish its technology on the market

Founders, August 2023 STABL Energy GmbH

Munich, August 9, 2023 – STABL Energy GmbH, a green tech start-up from Munich, has successfully completed its financing round of 15 million euros. Within the DACH region, the start-up thus receives one of the largest growth financing rounds in 2023 to date.

Two new investors believe in the start-up’s potential to make a significant contribution to the energy transition with its convenient, cost-effective, reliable and resource-efficient battery storage systems. Thanks to new investments from Nordic Alpha Partners’ Northern European Growth Fund and the European Innovation Council as well as funds from existing investors, the young company now has the financial basis to drive forward its vision of a CO2-neutral power supply and expand internationally.

STABL’s technology eliminates the risk of instability when used electric vehicle batteries are used for battery storage systems, taking an innovative and unique approach to the circular economy. STABL’s second-life battery storage systems thus offer a sustainable solution for energy storage, especially for commercial and industrial customers, the construction and real estate industry and the agricultural sector.

Strong partner from Denmark

Nordic Alpha Partners (NAP) from Denmark – one of Europe’s leading green tech growth funds – invests exclusively in sustainable hard tech companies that have the potential to drive and accelerate the global green transition. They support founders through their operational value creation model that helps visionary companies grow from local players to global market leaders.

Promoting breakthrough innovations

The European Innovation Council (EIC) initially funded STABL with a grant of two million euros for the further development of the technology. Now the EIC fund has provided STABL with additional capital to bring its breakthrough technology to market. Svetoslava Georgieva, Chair of the EIC Fund’s Board of Directors, said: “The EIC Fund is committed to supporting the green and digital transitions. It invests in companies that are able to deliver cutting-edge technologies to support this transformation and are in a clear position to scale their technologies and capture markets.” 
In addition to the Nordic Alpha Partners Fund II and the EIC Fund, existing investors UVC Partners with the Unternehmertum VC Fund III and the Smart Energy Innovation Fund of Energie 360 Grad are also participating in the €15 million financing round, thereby securing the growth of the Munich-based company. The fresh funds will be used to expand the customer base and further develop the technological infrastructure.

On course for growth through synergies

The collaboration is expected to further accelerate STABL Energy’s growth trajectory based on Nordic Alpha Partners’ operational value creation model. Dr. Arthur Singer, Co-CEO and co-founder of STABL Energy, commented on the new partnership as follows: “We have made considerable progress in a short period of time and have successfully installed our first second-life battery storage systems. In addition to a unique product, experience and partners are our key to success. Nordic Alpha Partners has an impressive track record as an investor and they convinced us with their unique approach to promoting and de-risking high growth and being at the forefront of technological change. The collaboration with the Danish investment company will be a valuable addition to our experienced investment team. We are excited about this partnership.” 

Dr. Nam Truong, also co-CEO and co-founder, adds: “We are delighted to have gained a strong and experienced partner for the coming years in Nordic Alpha Partners, who shares our philosophy and vision. It is particularly valuable that NAP understands our current and future challenges and is already helping us with its experience and network. The new partnerships are an important milestone for STABL to drive the energy transition through our battery storage systems.” 
Rasmus Lund, Senior Partner at Nordic Alpha Partners, added: “We see STABL Energy as one of the most promising GreenTech companies in the European storage market. We fully share the company’s vision and look forward to supporting the four founders and their team in their rapid expansion. The impressive growth and strong customer interest is a strong endorsement of STABL’s breakthrough technology and fits perfectly into Nordic Alpha Partners’ investment strategy. We look forward to the journey together with a shared vision to accelerate the path to ‘NetZero’ through a market-driven technology transformation.” 
With the successful financing round, STABL Energy has laid the foundation to both commercially expand and further develop its highly innovative battery storage technology architecture. 

Voices of existing investors

Existing investor, Johannes von Borries – Managing Partner of UVC Partners – says: “STABL solves two important problems for the energy transition: Firstly, the unique technology makes it possible to build very efficient and affordable storage systems. Secondly, used batteries from cars are made usable, thus extending their useful life by many years in line with the circular economy. This significantly reduces the CO2 footprint of the batteries and conserves resources.” 
Ruth Happersberger, Head of Strategy and Investments at Energie 360° and founder of Energie 360°’s Smart Energy Innovation Fund, said: “Our early investment in STABL Energy reflects our belief in STABL’s innovative approach to sustainable energy and its storage. The successful financing round underlines STABL’s key role in the energy transition. We look forward to continuing this journey with STABL, NAP, EIC, UVC and all investors to build a greener future.”
