  "account": "Swedish energy tech firm Rebaba has secured $4.6 million (SEK 44.1 million) in a seed round to scale its second-life battery storage solutions across Europe. The investment was led by venture capital firm Sistafund, alongside EIT Urban Mobility, with support from current shareholders and new European backers. Rebaba, founded by Paula Runsten and Felix Kruse, specializes in repurposing used electric vehicle (EV) batteries for stationary energy storage. Their technology integrates these batteries with proprietary systems to provide power for residential, commercial, and industrial uses. EV batteries often lose value before they reach their full lifespan, creating an opportunity for Rebaba to extend their utility. According to Rebaba, these batteries can retain 70 to 80 percent of their original capacity after being removed from vehicles. CEO Paula Runsten highlighted the growing demand for energy storage due to increasing electricity usage, the shift towards electrification, and the rise of renewable energy sources. She noted that repurposing EV batteries could satisfy this demand while minimizing the need for new batteries specifically designed for stationary storage. Rebaba's products include the Companion system, a small cabinet-based unit suitable for residential and small commercial settings, and the Containerised system, designed for larger commercial and industrial installations. Felix Kruse, co-founder and CTO, emphasized Rebaba's modular platform, which can work with various EV battery types while utilizing standard components for other system elements. This standardization allows for easy assembly by technicians worldwide. The company intends to use the new funds to expand its production facility in Stockholm to a capacity of 40 MWh annually and hire additional staff. Rebaba also aims to set up more CircularHubs in European countries as it enters new markets.",
