Flywheel Energy Storage Market Overview

The expanding energy storage and automobile industries have increased the demand in the market. The increased demand for UPS and data center application segments has driven the flywheel energy storage system market. In addition, the practice of distributed energy generation, which comprises the production of energy at the point of consumption, is projected to lead to increased demands for the systems.

The flywheel energy storage market offers many opportunities with the integration of renewable sources of energy and the need for a reliable storage solution for energy. With the ever-increasing use of solar and wind energy, the flywheel energy storage can solve the issues related to the fluctuations of energy by storing the surplus during peak hours of production and distributing it during a surge in demands.

The market is also constrained by various factors that may limit market growth. The initial cost associated with flywheels remains high, the cost of flywheel energy storage ranges from $1,500 and $6,000 per kWh. This makes it less attractive compared to other energy storage alternatives such as lithium-ion batteries.

Flywheel Energy Storage Market Dynamics

Market Drivers

Rising Focus on Grid Stability

• One of the recent trends in the global flywheel energy storage market is the increasing attention toward grid stability and resilience. With the growing deployment of renewable energy sources, such as wind and solar, which are growing steadily, the need to moderate the variability in power generation has increased, hence there is a need for energy storage solutions that will ensure stability in the grid. Flywheel energy storage systems provide rapid response times and fast charge/discharge capabilities and, as a result, can be used efficiently in offering voltage support, frequency regulations, and grid balancing services. Further, advances in flywheel technology, including better energy density, efficiency, and reliability, are driving the adoption of flywheels in various applications, including UPS systems and grid-scale energy storage. In addition, growing interests in decarbonization and sustainability further accelerate the demand for environmentally friendly flywheel energy storage as opposed to conventional, fossil fuel-based peaker plants to cater to temporary requirements for grid stabilization. Therefore, the need to enhance grid stability and resilience, combined with advancements in technology, is governing the trajectory of growth within the global flywheel energy storage market.

Increasing Demand for Electricity

• Energy storage systems can balance the electrical energy supply and demand by consuming the stored energy when the need is high, the generation cost is high, or when there is no other alternative available to generate energy. Demand for energy is increasing in the developing countries including Brazil, India, China, Russia, and South Africa. Thus, this has raised the energy prices. Energy storage systems are the need of the hour to aggregate the conventional generating plants to meet the growing demand and supplement the alternating Renewable Energy Storage (RES) for integration of these systems into the electrical network.

Market Restraints

Availability of Alternate Systems

• The rise in the use of alternate energy storage solutions is creating a few challenges for the growth of the flywheel energy storage market. These energy storage solutions are batteries, thermal storage schemes, Pumped Hydropower, Compressed Air, and others. For instance, the estimated capacity of pumped hydro energy storage, as estimated by the International Hydropower Association, is projected to grow by nearly 50% in order to reach 240 GW by 2030. Further, batteries are the most scalable form of storage, and the market has seen robust deployment in the recent past. As per the International Energy Association, the total investment in battery energy storage worldwide has exceeded USD 20 Billion in the year 2022, largely in the form of deployment in the grid-scale storage, which comprises more than 65% of the investments in 2022.

High Initial Capital Cost 

• One of the key restraining factors in the flywheel energy storage market is the high initial investment required with regard to the installation of the energy storage system and the use of high-quality material such as carbon rotors and magnetic bearings. Moreover, the applications of flywheels are more appropriate for short-term energy storage and quick discharge purposes rather than long-term energy shift applications. Due to these limitations on energy storage, the market growth is projected to be hampered in other applications such as extended energy backup systems.

Market Opportunities

Integration of Eco-friendly Storage Systems

• As a complement to the modern electricity grid, a high demand exists for a reliable, cost-efficient, durable, and environmentally sound energy storage system. Based on advancements in the fields of materials technology, bearings, and power electronics, the technology of fly wheels in energy storage systems has progressed considerably. With increasing development and application of this technology in the area of energy storage, several companies functioning in the market have been increasing their production capacities, thereby giving rise to the demand for flywheel energy storage.

Increasing Demand for Fast-response Grid Stabilization Solutions

• One of the major opportunities in the market for flywheel energy storage is the requirement for fast-response, high-cycle energy storage. With the increased usage of renewables in the energy mix, as well as the increased usage of digital data, there will be an increased requirement for instant frequency, as well as voltage control. Flywheels provide high lifespan, non-degrading, high rate-of-charge-and-discharge performance, which makes them an attractive solution in these areas.
