Croatian companies ENNA and Rimac Energy established a strategic partnership for the production and storage of renewable energy. The central point is SineStack, an innovative battery energy storage system developed by Rimac Energy.

The partnership was declared at Birmingham Tech Week, the most significant regional technology fair in the United Kingdom. At the event, Rimac Energy presented SineStack, its most advanced battery energy storage system (BESS), ENNA said.

ENNA develops solar and geothermal projects and operates in transport, logistics, and food production and distribution. Rimac Energy is a brand of Rimac Technology owned by Rimac Group. It specializes in designing, developing, and manufacturing innovative stationary energy storage systems (ESS) solutions in Europe.

Companies plan to launch initial pilot projects in 2024

ENNA said it would harness the potential of renewable resources, including wind and solar energy, while that Rimac Energy is set to store and deliver the power via ESS.

According to Rimac Energy, both companies intend to deploy SineStacks to ENNA’s grid-tied renewable energy investments and beyond.

The first pilot project will be delivered to ENNA’s sites in 2024, enabling the partnership to refine the plans, Rimac Energy said.

The companies could also deploy up to 1 GW of energy storage systems

According to ENNA, they are committed to pursuing additional projects, including the deployment of energy storage systems of up to 1 GW in total.

SineStack contains innovations that push down the levelized cost of storage, increase round-trip efficiency and significantly improve energy stored per square meter, Rimac Energy stressed.

The company claimed that the solution enables a system lifetime of up to 12,000 cycles and more than 92% round-trip efficiency and draws all energy from every cell, minimizing inaccessible energy during operation.

The integrated power conversion system also allows customers to add 790 kWh blocks at a time without the need for inverter changes or additions.

SineStack pushes the limits of what grid-tied batteries can offer customers

Zoran Miliša, CEO of ENNA Opskrba, said that SineStack introduces the next generation of energy storage systems.

“We could not wish for a better partner to realize our shared ambitions for sustainability and pioneering development of energy storage solutions in key markets in Southeast Europe,” he stressed.

Sarwar Dilov: We can’t wait to see SineStack in customers’ hands across Europe

According to Wasim Sarwar Dilov, Rimac Energy CEO, SineStack pushes the limits of what grid-tied batteries can offer customers.

“We can’t wait to see SineStack in customers’ hands across Europe, and we are ramping up our European production to meet demand,” he said.
