HOME / bidirectional energy storage technology the game changer in
Bidirectional charging technology has the potential to save billions of euros annually by optimizing electricity usage and reducing system costs. A recent study by Transport & Environment (T&E) reveals that this innovative technology could transform Europe's energy and mobility sectors.
Bidirectional charging (BiDi) could thus achieve a technological and economic breakthrough in Europe but it requires clear regulatory framework conditions. Without these, the potential will remain untapped.
The event will take place from May 7–9, 2025, at Messe München. The Fraunhofer Institutes estimate that the savings potential from bidirectional charging in the EU could amount to up to €22 billion annually, equivalent to around 8% of the costs of constructing and operating the EU energy system.
A new study by Transport & Environment (T&E) shows that this could save billions by optimizing the use of generation capacity, reducing curtailment, and lowering fuel consumption. Bidirectional charging (BiDi) could thus achieve a technological and economic breakthrough in Europe but it requires clear regulatory framework conditions.
We will explore its advantages, applications across various industries, and a comparative analysis with other storage methods. Flywheel technology is a sophisticated energy storage system that uses a spinning wheel to store mechanical energy as rotational energy. This system ensures high energy output and efficient recovery.
The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs).
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
A dynamic model of an FESS was presented using flywheel technology to improve the storage capacity of the active power distribution system . To effectively manage the energy stored in a small-capacity FESS, a monitoring unit and short-term advanced wind speed prediction were used . 3.2. High-Quality Uninterruptible Power Supply
