Electric vehicle technology specialist launches stationary energy storage business

Rimac Technology, a Croatian developer of EV components and systems, is entering the stationary energy storage systems (ESS) market with the launch of Rimac Energy.

The new business has created a novel battery architecture claimed to reduce efficiency losses by up to 50 per cent whilst decreasing the system footprint by up to 40 per cent compared to current advanced solutions.

Additional technological benefits include improved cycle life, and built-in redundancy for increased availability.

Teddy Szemberg O’Connor, Rimac Energy’s advanced battery software manager, said the solution is highly scalable - enabling systems ranging from 770kWh to over 1GWh - and designed to meet the specific needs of the company’s customers.

“We then select from a set of common building blocks, providing an optimal solution,” he said. “Our clean-sheet design takes the best learning from our vehicle technology and tailors it for stationary storage. Large-scale manufacturing is key; we are set to start mass manufacturing in 2025, scaling up to double digit GWh.”


Rimac Energy will focus primarily on continental Europe where primary use cases will be for large commercial, industrial, and utility-scale applications. Battery-buffered solutions for fast and MW charging are underway also, the company said.

Szemberg O’Connor added that Rimac Energy is developing systems to be battery cell chemistry agnostic and that the company is working on multiple cell chemistries to offer its customers systems that best fit their needs.

The company currently has several customer projects in discussion, including a pilot with a renewable energy company to provide battery storage solutions for their solar and wind power plants. These pilot systems are expected to be produced by the end of this year and commissioned in 2024.

Rimac Energy’s technology is being developed and manufactured at Rimac’s facilities on the outskirts of Zagreb, Croatia and will be revealed later this year.
