Kinetic Energy Storage

As opportunities for renewable power generation and power storage grow in the energy sector, the flywheel is resurging as a highly implementable energy storage solution globally. At its element, a flywheel is a mechanical battery that stores energy in the form of kinetic energy, resulting from electrically induced high rotational velocity. Although, the rotational velocities of traditional flywheels were less than 10,000 Revolutions per Minute (rpm), advancements in our current flywheel model seek to achieve an increase in rotational velocity, ranging from 60,000-100,000 rpm, by reducing and optimizing the overall mass of the flywheel to less than 10 kg.

Our flywheels have a high likelihood for improving energy storage, enhancing power reliability, and reducing manufacturing costs, therefore making it a superior option for large scale power management and Uninterruptible Power Supply (UPS). Depending on regulations surrounding licensed configurations in each country, our flywheels can be potentially used worldwide as a primary energy storage solution to meet power demands for multiple grid systems.

Our flywheel design guarantees low impacts on the environment as it is not dependent on the use of water or fuels as working components, has zero air emissions and does not discharge hazardous waste by-products. The small mass and high energy storage of our flywheel coupled with an existing demand for high energy consumption offers a competitive advantage for its use in both large industrial systems (frequency control, railway transport) and in systems with low power consumption (underground stations, trams, trolleybus). Besides applications in large-scale power grids and UPS, our flywheel can be used in a variety of applications in multi-billion dollar sectors of the automotive industry, electrification of rail brake systems, and space science laboratories.

Currently, the global energy storage market is worth more than $21.4 billion and consists of 3 categories: UPS, power system support and large power system management. Billions of dollars are continually invested in the optimization of energy infrastructure, to build more flexible systems with high performance and the low construction, operations, and maintenance costs. At the same time, the market volume is growing at a rate of approximately 20% per year.

Due to advancements in design and improved efficiency of our flywheel we guarantee a much more affordable cost of installation than the current estimate of $1,500 – 6,000 USD per kWh. We have conducted experiments on a prototype to test rotational velocities of more than 100,000 rpm. Our prototype was also reviewed for the integrity of its associated structural elements at such high velocities and no violations were found. This leads us to conclude that our flywheel is a safe and superior energy storage option available with state-of-the-art features.
