The Short Version
Rebaba is an early-stage Stockholm cleantech company building containerized energy storage systems from repurposed electric vehicle batteries. The company’s founding in 2023 coincides with a critical inflection point in European energy policy and battery supply chains. Founders Paula Runsten and Felix Kruse bring direct experience from Northvolt and Tesla [RocketReach.co]. Their product, marketed through an initial wholesale partnership with KP Energy, targets commercial and industrial customers seeking cost-effective storage [KP Energy, 2024].
Financing is in a pre-seed phase, with a company announcement citing a 5.5 million SEK raise [rebaba.se]. The business model is B2B, focusing on hardware sales and deployment of standardized container units. Over the next 12-18 months, key signals include the scaling of the partnership with Smartports, commercial traction following the KP Energy launch, and the company’s ability to secure a larger funding round.

The Company in Brief
Rebaba was founded in 2023 in Stockholm, Sweden, with a focus on extending the lifecycle of electric vehicle batteries [rebaba.se]. In 2024, the company's containerized product was featured in a brochure from Swedish energy wholesaler KP Energy [KP Energy, 2024]. In October 2025, Rebaba announced a collaboration with Smartports to scale circular battery-powered solar carports across Europe [news.cision.com, 2025]. The company also participates in a Vinnova-funded industrial scaling project alongside Stena Recycling and RISE Research Institutes of Sweden [miningmetalnews.com, 2025].
Data Accuracy: YELLOW -- Core founding details confirmed by company website; partnership announcements corroborated by third-party press. Funding specifics rely solely on company announcement.
What They Have Built
Rebaba builds stationary energy storage systems by repurposing used electric vehicle batteries into containerized units. The company claims its systems feature “automotive-grade performance and state-of-the-art safety” [rebaba.se]. The collaboration with El och Marinteknik for a grid-connected system suggests integration work with electrical engineering partners [cbinsights.com]. The “Made in Sweden” supply chain is highlighted as a point of differentiation [rebaba.se].
Data Accuracy: YELLOW -- Product description and key partnerships are confirmed by company and partner sources; technical specifications and performance data are not publicly detailed.
Market Size and Demand
The market for second-life battery energy storage is driven by electrification and the need for grid stability. According to BloombergNEF, the global market for stationary energy storage is projected to reach 679 gigawatt-hours annually by 2030 [BloombergNEF, 2024]. By 2030, the volume of batteries reaching end-of-life in EVs is expected to surpass 200 gigawatt-hours per year globally [Circular Energy Storage, 2023]. The European Union's Battery Regulation mandates increasing levels of recycled content, incentivizing circular battery business models [European Parliament, 2023].
| Metric | Value |
|---|---|
| Global Stationary Storage Market (2030 projection) | 679 GWh |
| Annual EV Batteries Available for 2nd Life (2030 projection) | 200 GWh |
Data Accuracy: YELLOW -- Market sizing figures are from cited third-party reports (BloombergNEF, Circular Energy Storage) and provide a relevant analogous context.
Who Else Is Fighting for This
Rebaba's position is defined by a focus on second-life EV battery systems for the commercial and industrial sector.
| Company | Positioning | Stage / Funding | Notable Differentiator |
|---|---|---|---|
| Rebaba | Second-life EV battery storage for C&I | Pre-seed (~5.5 million SEK) | Circular supply chain focus, 'Made in Sweden' assembly |
| BatteryLoop | Second-life battery storage solutions | Venture-backed (Series A) | Part of Stena Recycling group |
| Fortum | Energy company with battery storage services | Publicly traded | Utility-scale projects, deep balance sheet |
| Octave | AI-powered energy storage optimization software | Venture-backed | Software-only, agnostic to battery hardware |
| Evyon | Second-life EV batteries for stationary storage | Venture-backed | Proprietary diagnostics and repackaging technology |
Data Accuracy: YELLOW -- Competitor identification is confirmed, but detailed funding and differentiation claims for rivals are inferred from general market knowledge.
Opportunity
Rebaba aims to become a provider of standardized, containerized second-life battery systems for commercial and industrial energy management. Early execution includes a strategic collaboration with Smartports to scale circular battery-powered solar carports [news.cision.com, 2025] and participation in a Vinnova-funded industrial scaling project [miningmetalnews.com, 2025].
Data Accuracy: YELLOW -- Opportunity framing relies on confirmed partnerships and project participation; growth scenarios are extrapolations from these early signals.
