7 Companies Researching Hybrid Energy Storage System
We all know that the energy crises have been weighing down the world. But what exactly is the problem with energy storage systems? And how can a Hybrid energy storage system help overcome this problem?
Well, typically, both power and energy are required. But the two types of the single-nature energy storage system (ESS), i.e., ESSs for high-energy systems and ESSs with high-power capability, either provide energy for hours or even several days or offers high amounts of instantaneous power but with reduced discharge times in the range of seconds to minutes.
As a result, the traditional ESS approach of using only one energy storage technology frequently results in suboptimal solutions, despite the well-known tradeoff between system performance and overall cost.
A Hybrid Energy Storage System (HESS) is an optimal solution for mitigating this issue.
HESS comprises two or more types of energy storage systems that work together to outperform any single-component energy storage device. These include batteries, flywheels, super-capacitors, and fuel cells.
The system is poised to be the long energy solution for micro-grids and a sustainable alternative for energy production in standalone applications.
Further, hybrid storage provides additional cost-cutting opportunities; two or more units can utilize much of the same power electronics and grid connection gear, lowering initial and ongoing expenses. (Source)(Source)(Source)(Source)
The following are three forms of hybrid storage that have emerged beyond the pilot stage:
- Power-to-heat/battery
- Battery/Battery
- Ultracapacitor/battery
Global Hybrid Energy Storage Market
In 2021, the global hybrid energy storage system market was valued at $11.93 billion and is expected to increase and reach $22.30 billion by 2030. The market anticipates HESS to grow at an approximate CAGR of 7.2% during the forecast period.
A boost in demand for high-energy storage systems for load shifting and an expansion in small and medium-sized businesses are driving its market expansion. (Source)

Hybrid Energy Storage System Advantages
Provide both high energy and high power system – Hybrid energy storage system is made up of two or more ESSs, so it could provide both high energy and high power system that other ESSs don’t offer.
So, Hybrid ESS can provide a high amount of instantaneous power for an extended time. (Source)
Improved utilization of existing energy resources – Hybrid energy storage systems improve the overall efficiency of existing energy systems by reducing looping and changing output, resulting in reduced emissions and a smaller carbon footprint. A high-power-operations-capable technology increases system efficiency for applications that demand storage to address short-term power fluctuations, such as renewables ramping/smoothing. Utilizing the same hybrid system for low-power, long-duration applications such as backup power, on the other hand, will maintain its overall health. (Source)
Other Advantages: Hybrid Energy Storage System (HESS) flexibility permits the coverage of a broader range of applications, which is impossible with a single-nature ESS.
Taking into account one specific application, using a HESS allows for avoiding the oversizing of a single-nature ESS; this can reduce the cost of the system (in some cases, by up to 15%).
Introducing a new ESS in the system to build a HESS reduces the stress of the principal ESS, significantly extending its lifetime (up to 40% in some cases). (Source)
Hybrid Energy Storage System Challenges
Limited Energy Production – The Hybrid Energy Storage System may encounter obstacles since the storage system’s limited energy production will be restricted to the quantity of energy stored. The absence of power flow control and energy management options results in inefficient storage utilization. (Source)
