New standards in Energy Storage Technology: We are the Efficiency Champion!

STABL Energy has achieved a significant breakthrough in energy storage: In the latest efficiency tests conducted by TotalEnergies, impressive round-trip efficiencies (RTE) of 90.8% and 93.4% were measured. Our values are far above the industry standard of 75% to 85% and illustrate our potential to transform the energy storage industry in the long term.

High efficiency even under extreme conditions

Total’s tests aimed to validate the exceptionally high efficiency of STABL’s energy storage technology. Remarkably, these values were achieved even when using heavily aged battery modules. The tests with modules that only have low and varying functional capacities after a few years of operation put our technology to the test, a challenge that we mastered with flying colours.

What does Round Trip Efficiency mean?

Round-trip efficiency (RTE) is a key indicator for evaluating energy storage systems. It indicates how efficiently a system can absorb, store, and release energy from the power grid without significant losses. Therefore, a high RTE is extremely important to keep energy storage costs low and to optimise the system’s overall performance.

Proving the Potential of Modular Energy Storage

We take an innovative modular approach to building energy storage systems. Compared to conventional products in the market, this can reduce energy losses by up to 70 % and cut operating costs by up to 40% while keeping investment costs low. The dynamic interconnection of the modules also ensures that the weakest battery does not affect the system’s overall performance.
