Levron Dynamics - Flywheel Energy Storage System for Power Grid Stabilization

AI Quick Summary

Die Umstellung auf ein erneuerbares Stromnetz erfordert mehr als nur das implementieren von immer mehr renewables– jede Windturbine und jedes Solarmodul muss in das Stromnetz integriert werden, ohne den stabilen Betrieb des Netzes zu beeinträchtigen. Aus diesem Grund ist unser Ziel bei Levron Dynamics, ein Schwungrad-Energiespeichersystem zu entwickeln, das dem Stromnetz primäre und sekundäre Regelreserven zur Verfügung stellen kann, um einen Betrieb mit 100% erneuerbaren Energiequellen zu ermöglichen.

Project Idea Description

Challenge

Within the European power grid, the imperative is for electricity production to consistently match the demand in real time. Any deviation from this equilibrium results in a frequency shift from the critical 50 Hz benchmark. Even minor deviations can disrupt the grid and lead to potentially catastrophic blackouts.

Sustaining stable operation of the power grid requires the energy producers to maintain control reserves. In the event of an unforeseen power plant outage or an unexpected spike in demand, it becomes essential to rapidly redistribute the energy from the grid to reestablish the balance between production and consumption.

Nowadays, a substantial part of primary and secondary control reserves are supplied by the rotational inertia of turbines in nuclear and combustion power plants. Yet, as the shift towards renewable energy gains momentum, these turbines are gradually phased out of the grid. This impending transition poses the critical challenge for power grid stability in the years ahead. Compounding on this issue: energy generation from renewable sources displays higher volatility, necessitating increased capacity of control reserves.

Solution

Our objective centers on the development of a Flywheel Energy Storage System (FESS), tailored to upholding control reserves. The FESS converts rotational energy into electrical energy and vice versa, achieving remarkable rotational speeds of up to 35,000 rpm. High speed goes hand in hand with high energy density and rapid energy dispatch.

This performance is made possible by our innovative patent pending passive magnetic bearing system [DE102018002179A1], which is the first milestone of this project. Compared to active magnetic bearings available on the market, our suspension system does not require complicated control systems, which allows us to cut system costs, increase safety and shorten the commissioning time.

Market Opportunity

The market for control reserves already exists in Switzerland and is structured by a tender-system. Among early adopters of our technology, we are looking for collaborations among 15 energy companies already taking part in the market. After this, we aim to be able to provide 213 electricity producers in Switzerland with our viable FESS technology. The goal is to develop the technology serving to uphold control reserves across the European continent.

Value Proposition

FESS distinguish themselves from other Energy Storage Technologies through its rapid responsiveness, prolonged operational lifespan, and a comparatively modest capital investment per power unit. Notably, flywheels exert a significantly lower environmental impact than batteries, without the use of any toxic materials.
