Rimac Energy, a division of Rimac Technology, represents a significant advancement in stationary energy storage solutions. The company specializes in developing high-performance battery energy storage systems (BESS), building upon the expertise gained from its parent company’s success in electric vehicle technology. Founded by Mate Rimac, this European-engineered venture aims to transform the energy storage sector through innovative battery solutions. Their flagship product, SineStack, exemplifies their commitment to efficiency, delivering exceptional performance with a 92% round-trip efficiency and an impressive 12,000-cycle lifetime capability.
Battery Technology
The company’s technological foundation centers on its SineStack system, which incorporates advanced lithium iron phosphate (LFP) cells. This system features a distributed inverter architecture, often described as an “AC battery,” enabling precise control and enhanced redundancy across modules. The electrical design reduces energy losses by up to 50% compared to existing solutions while decreasing the system footprint by 40%.
SineStack’s integration of power conversion systems and liquid thermal management results in near-silent operation and optimal space utilization. The system’s intelligence extends to state-of-health monitoring and prediction algorithms, ensuring consistent energy capacity throughout its operational life. Their in-house Operating Platform EMS also utilizes advanced analytics for automated operations, offering detailed insights into system performance and battery health monitoring.
Production plans include manufacturing these systems at the Rimac Campus in Croatia, with pilot systems being tested. The company anticipates reaching full-scale production by 2025, with a projected annual capacity exceeding 10GWh.
Recent Projects
In early 2024, Rimac Energy initiated the deployment of its SineStack system at a site in Colchester, UK. The company has guaranteed zero energy capacity fade for the first two years of operation starting in 2025. Additionally, Rimac Technology established a partnership with the BMW Group to develop high-voltage battery solutions for electric vehicles. The company also announced collaboration with ENNA, a Croatian renewable energy company, for strategic energy storage projects.
Investors
Rimac Energy operates under the Rimac Group umbrella and is supported by notable investors, including SoftBank Vision Fund 2, Goldman Sachs Asset Management, Porsche, and InvestIndustrial. Mate Rimac maintains his position as the largest shareholder, while Hyundai Motor Group continues as a strategic investor. These partnerships provide substantial financial backing and industry expertise to support the company’s expansion plans.
