Advantages of Using Battery Energy Storage System

Self-Sufficiency

Battery energy storage systems aren’t simply appealing to renewable energy providers but are also being adopted by forward-thinking enterprises. Energy purchased during off-peak hours can be stored using battery storage systems. It can be activated to distribute electricity when tariffs are at their highest, hence lowering energy expenses. Battery storage systems can also be set up to function as an uninterrupted power source. This is a useful insurance policy for enterprises.

Integration of the Grid

Renewable energy is fed directly into the grid, where it is available to customers. However, grid demand swings, with highs and lows. Battery storage systems now provide a viable and cost-effective solution for medium-sized renewable energy producers to capture the electricity generated. When working with electricity, safety is critical. This is why experts install and set up the import/export controller and converter to ensure safe functioning and overload protection.

Frequency Control

Battery storage systems can control grid frequency, ensuring that it is within the needed range. The frequency can go above or below its nominal value if the power generated doesn’t match the real electricity consumption. Such inconsistencies may cause temporary disconnections, power outages, or blackouts. BESS can respond promptly to power outages, offering sub-second frequency response and grid stabilization.

Shift in Energy Time

Energy time-shifting is possible with battery energy storage systems. Energy is purchased at a low cost during off-peak intervals and sold or consumed when the price rises. As a result, regardless of the season or electrical demand, BESS can equalize energy prices and reduce risks. (Source)(Source)

Challenges of Battery Energy Storage System

Installing BESS necessitates a significant capital outlay

Due to their high energy density and enhanced performance, battery energy storage technologies such as lithium-ion batteries, flow batteries, and lead-acid batteries necessitate higher installation investments. Lithium-ion batteries are expensive because they have a high energy density, a low rate of self-discharge, and need minimal maintenance. Furthermore, the high upfront investment cost necessary for flow battery manufacturing may function as a key obstacle to market growth.

Installation of BESS in remote locations

Battery energy storage devices are mostly used in remote locations.  These systems are challenging to deploy in remote places because they are tough to reach. Islands and off-grid distant places are common examples of remote regions that confront a variety of issues due to fluctuating production and supply of power from renewable energy sources. Ambient circumstances such as temperature variation during the day and night, costly maintenance due to commuting problems to these sites, and a shortage of equipment installation facilities are all challenges.

Trend 3: Thermal Energy Storage

Thermal Energy Storage System (TES) is a technology that stores thermal energy by heating or chilling a storage medium so that it can be used for heating and cooling purposes as well as power generation. TES devices are extremely useful in construction and industrial processes. TES is a collection of technologies that use various methods to store accessible heat energy in insulated repositories. A TES system typically consists of a tank storage medium, a compact cooler or built-up refrigeration system, pipework, pumps, and controls.

The TES system can hold vast amounts of energy safely, and its regular self-loss is minimal (0.05-1%). The reservoir has a high energy density and specific energy (80-500 W h/L, 80-250 W h/kg). The system is financially feasible with a low capital cost (3-60 $/kW h). The cycle efficiency of TES systems, on the other hand, is often low (30-60%). (Source)(Source)(Source)

In 2020, the global thermal energy storage market was valued at $20.8 billion and is expected to increase and reach $51.3 billion by 2030. The market is expected to increase at an approximate CAGR of 8.5% during the forecasted period. The COVID-19 epidemic reduced demand for thermal energy storage devices due to a global standstill in the production, construction of utility infrastructure, and renewable energy infrastructure due to government-imposed lockdown restrictions.

Advantages of Using Thermal Energy Storage System

Energy efficiency improvement

Increased energy efficiency is one of the benefits provided to power systems by thermal energy storage. District heating systems, for example, promote energy efficiency by conserving heat and then utilizing it as required. As a result, less fossil fuel is needed, and plant emissions are decreased, resulting in lower product costs. However, TES cannot deliver these advantages on its own. To contribute to improved energy management, it must be helped by intelligent control systems and information and communication technologies (ICT).

Boost generating capacity

The need for heating, cooling, or power is rarely consistent over time. The surplus production capacity available during low-demand periods can be charged to a TES to improve efficient generation capacity during high-demand periods. This procedure enables the installation of a smaller manufacturing unit, resulting in a higher load capacity for the units.

Minimal maintenance cost

Thermal storage systems have lower maintenance expenses since they use smaller chillers, cooling towers, and pumps than conventional technologies. While increasing hours of operation may somewhat negate these savings, stops, and starts have a greater impact on maintenance than hours of operation. Furthermore, a conventional system often operates in a partial-load mode for the majority of the year, which is equally demanding maintenance as a full-load operation. (Source)(Source)(Source)(Source)

Challenges of Thermal Energy Storage System

Expensive initial setup costs

Thermal energy storage system costs vary according to application, size, and heat insulation technique. Thermal storage technologies based on phase transition materials and thermo-chemical storage are typically more expensive than the storage capacity they offer. Storage systems account for about 30% to 40% of total system costs. Latent-heat storage systems built on PCMs are predicted to cost between Є10/kWh-50/kWh ($10.7/kWh-53.5/kWh), whilst TCS expenses are expected to be between Є8/kWh-100/kWh ($8.56/kWh-107/kWh). The economic feasibility of a TES is strongly dependent on application and operation requirements, such as the quantity and frequency of storage cycles.

Boosted competition from pumped storage and battery storage

Understanding the benefits of battery and thermal energy storage is critical for utilities and power plant managers. Batteries are excellent for providing standby power for lights, elevators, and computers. Whereas, thermal energy storage is the simplest approach for a structure to reduce peak electric consumption. The majority of battery storage projects developed by system operators (ISOs/RTOs) are for short-term energy storage and are not designed to replace the existing grid. The majority of these installations employ lithium-ion batteries, which produce enough energy to power the local grid for 4 hours or fewer. Even though thermal energy storage requires lower project costs, it is not as desired as battery storage and pumped-hydro storage due to lesser efficiency at larger scales. As a result, these replacements function as obstacles to the expansion of the thermal energy storage sector. (Source)(Source)(Source)

Trend 4: Distributed Energy Storage System

A Distributed Energy Storage (DES) System is a pre-packaged solution for storing energy for later consumption. The two essential parts of the system are the DC-charged batteries and the bi-directional inverter. This equipment is housed in a shipping-friendly chassis that can endure harsh conditions. Distributed energy storage systems utilize lithium-ion batteries and advanced technologies to collect and discharge excess power quickly. Thus, providing users with a variety of benefits. (Source)(Source)

In 2021, the globally distributed energy storage market was valued at $11.70 billion and is expected to increase and reach $19.20 billion by 2027. The market is expected to grow at an approximate CAGR of 8.6% during the forecast period. In 2021, the Asia-Pacific region held the highest market share of 33%, out of the globally distributed energy storage market, due to rising electricity demand in this area, increasing buying power, and growing investment in renewable energy projects.

The International Energy Agency (IEA) estimated that the annual expenditure needed to fulfill global energy demand would reach $1.9 trillion in 2021. Distributed energy storage systems assist in the conservation of excess energy generated for use during power outages. In 2021, according to the IEA, China’s investments in renewable energy production were approximately 30% of global investments. (Source)(Source)(Source)

There will be significant climate advantages if it is used to increase reliance on renewables. Electric vehicles utilized as distributed energy storage can have a big impact on the environment.

System-level capacity

DESSs add value to the system by deferring or avoiding investment in generation and transmission assets. DESSs’ system capacity value is determined by their utilization capacity during peak load times. When DESSs are utilized to enhance supply or reduce consumption on the grid in place of central generators that would normally be employed in the event of a contingency, such as a forced outage, they provide operating reserve value. (Source)(Source)

Challenges of Distributed Energy Storage System

Expensive setup and battery costs

The upfront cost of distributed energy storage systems is significant, and the ongoing maintenance costs are even higher. Rising pricing of numerous key minerals used in battery manufacture, supply chain disruptions caused by the Russia-Ukraine conflict, and COVID-19 lockdowns in some regions of China have all acted as a barrier to the expansion of the market.

Thermal exhaustion and expensive capital investment

Even though the Distributed Energy Storage industry is quickly expanding, the thermal instability issue of batteries is impeding its expansion. Internal cell faults, mechanical failures or damage, or excess voltage are the primary causes of thermal runaway, which results in high temperatures, gas buildup, and potentially catastrophic rupture of the battery cell, ending in fire or explosion. Aside from that, this market necessitates a substantial capital expenditure to manufacture such a system. As a result, the aforementioned issue will hinder the expansion of this market.

Challenges of Advanced Lithium-Ion Batteries

Excessive Heating

Batteries are utilized in a variety of applications, including automobiles, electrical systems, and civil airlines. These batteries can store very significant amounts of energy in compact places, but they heat up quickly and may catch fire if something goes wrong with them. Overheating of the batteries can occur as a result of high-rate discharge or an anomalous rate of discharge, such as a short circuit. This phenomenon is called thermal runaway. (Source)

Conclusion

The energy crisis in Europe has affected the continent to a great extent. Its repercussion can be felt in other parts of the world too. 

Europe has the alternative of gas for producing energy such as nuclear plants. But some disasters have made Europe think twice to use nuclear power plants for energy production.

Take Germany for example. Nuclear power, generated by six power plants, accounted for 13.3% of the German electricity supply in 2021. But they shut down three plants at the end of 2021, with the other three set to close by the end of 2022, according to the 2011 nuclear phase-out plan.

Nuclear is a good option but it certainly comes with big disasters like Chernobyl and Fukushima. So, the energy sector needs other options and innovation trends to tackle this crisis and to enhance energy storage. 

The global market trend of energy storage is growing at a fast pace. (Source) The graph below shows how it would be growing 15-fold by 2030. 

Global Cumulative Energy Storage Installations

An estimated 387GW/1,143GWh of new energy storage capacity will be added globally from 2022 to 2030 – more than Japan’s entire power generation capacity in 2020. The US and China are set to remain the two largest markets, representing over half of the global storage installations by the end of the decade.

These metrics tell us that the future is bright for the energy storage sectors. However, nothing can be taken for granted. Nature or geopolitical battles can make things worse. So, it’s better for countries and companies to prepare now.
