Grid-scale storage plays an important role in the Net Zero Emissions by 2050 Scenario, providing important system services that range from short-term balancing and operating reserves, ancillary services for grid stability and deferment of investment in new transmission and distribution lines, to long-term energy storage and restoring grid operations following a blackout.
pumped-storage hydropower is the most widely used storage technology and it has significant additional potential in several regions. Batteries are the most scalable type of grid-scale storage and the market has seen strong growth in recent years. Other storage technologies include compressed air and gravity storage, but they play a comparatively small role in current power systems. Additionally, hydrogen – which is detailed separately – is an emerging technology that has potential for the seasonal storage of renewable energy.
While progress is being made, projected growth in grid-scale storage capacity is not currently on track with the Net Zero Scenario and requires greater efforts.
The total installed capacity of pumped-storage hydropower stood at around 160 GW in 2021. Global capability was around 8 500 GWh in 2020, accounting for over 90% of total global electricity storage. The world''s largest capacity is found in the United States. The majority of plants in operation today are used to provide daily balancing.
The grid-scale battery technology mix in 2022 remained largely unchanged from 2021. Lithium-ion battery storage continued to be the most widely used, making up the majority of all new capacity installed.
The rapid scaling up of energy storage systems will be critical to address the hour‐to‐hour variability of wind and solar PV electricity generation on the grid, especially as their share of generation increases rapidly in the Net Zero Scenario. Meeting rising flexibility needs while decarbonising electricity generation is a central challenge for the power sector, so all sources of flexibility need to be tapped, including grid reinforcements, demand‐side response, grid-scale batteries and pumped-storage hydropower.
Grid-scale battery storage in particular needs to grow significantly. In the Net Zero Scenario, installed grid-scale battery storage capacity expands 35-fold between 2022 and 2030 to nearly 970 GW. Around 170 GW of capacity is added in 2030 alone, up from 11 GW in 2022. To get on track with the Net Zero Scenario, annual additions must pick up significantly, to an average of close to 120 GW per year over the 2023-2030 period.
Based on cost and energy density considerations, lithium iron phosphate batteries, a subset of lithium-ion batteries, are still the preferred choice for grid-scale storage. More energy-dense chemistries for lithium-ion batteries, such as nickel cobalt aluminium (NCA) and nickel manganese cobalt (NMC), are popular for home energy storage and other applications where space is limited.
Besides lithium-ion batteries, flow batteries could emerge as a breakthrough technology for stationary storage as they do not show performance degradation for 25-30 years and are capable of being sized according to energy storage needs with limited investment. In July 2022 the world''s largest vanadium redox flow battery was commissioned in China, with a capacity of 100 MW and a storage volume of 400 MWh.
Moreover, the impacts of Russia''s invasion of Ukraine are also apparent in the battery metals market. Both cathode (nickel and cobalt) and anode (graphite) materials are affected. Russia is the largest producer of battery-grade Class 1 nickel, accounting for 20% of the world''s mined supply. It is also the second and fourth largest producer of cobalt and graphite respectively.
Ranging from mined spodumene to high-purity lithium carbonate and hydroxide, the price of every component of the lithium value chain has been surging since the start of 2021. 2022 saw the first increase in the price of lithium-ion batteries since 2010, with prices rising by 7% compared to 2021. Some relief was observed only in the first quarter of 2023.
Global investment in battery energy storage exceeded USD 20 billion in 2022, predominantly in grid-scale deployment, which represented more than 65% of total spending in 2022. After solid growth in 2022, battery energy storage investment is expected to hit another record high and exceed USD 35 billion in 2023, based on the existing pipeline of projects and new capacity targets set by governments.
The most significant investment in new pumped-storage hydropower capacity is currently being undertaken in China: Since 2015, the vast majority of final investment decisions for new capacity have been take there, with additions far exceeding those in other regions.
Governments should consider pumped-storage hydropower and grid-scale batteries as an integral part of their long-term strategic energy plans, aligned with wind and solar PV capacity as well as grid capacity expansion plans. Flexibility should be at the core of policy design: the first step needs to be a whole-system assessment of flexibility requirements that compares the case for different types of grid-scale storage with other options such as demand response, power plant retrofits, smart grid measures and other technologies that raise overall flexibility.
In liberalised electricity markets, long lead times, permitting risks and a lack of long-term revenue stability have stalled pumped-storage hydropower development, with most development occurring in vertically integrated markets, such as in China. Dedicated support mechanisms, such as capacity auctions for storage, could help promote deployment by providing long-term revenue stability for pumped-storage hydropower and battery storage plants.
Regulatory frameworks should continue to be updated to level the playing field for different flexibility options, which would help to build a stronger economic case for energy storage in many markets. One example would be ending the double charging of taxes or certain grid fees.
In liberalised electricity markets, measures to increase incentives for the deployment of flexibility that is able to rapidly respond to fluctuations in supply and demand could help improve the business case for grid-scale storage. These include decreasing the settlement period and bringing market gate closure closer to real time, as well as updating market rules and specifications to make it easier for storage to provide ancillary services. The business case for storage improves greatly with value stacking, i.e. allowing it to maximise revenue by bidding into different markets.
The production of critical minerals used in the production of batteries is highly concentrated geographically, raising security of supply concerns. The Democratic Republic of Congo accounts for 70% of the world''s cobalt production, while Australia and Chile combined account for 75% of global lithium production. In the midstream segment, China dominates the announced refining capacity (95% for cobalt and around 60% for lithium and nickel).
A comprehensive suite of policies in support of minerals security needs to include recycling. Battery recycling has the potential to be a significant source of secondary supply of the critical minerals needed for future battery demand. Targeted policies, including minimum recycled content requirements, tradeable recycling credits and virgin material taxes all have the potential to incentivise recycling and drive growth of secondary supplies. International co-ordination will be crucial because of the global nature of the battery and critical minerals markets.
Batteries that no longer meet the standards for usage in an electric vehicle (EV) typically maintain up to 80% of their total usable capacity. With EV numbers increasing rapidly, this amounts to terawatt hours of unused energy storage capacity. Repurposing used EV batteries could generate significant value and benefit the grid-scale energy storage market.
With 60% of global greenhouse gas emissions coming from energy, there''s a universal need to make our power system as clean and cost-effective as possible. Renewable energy sources like solar and wind are excellent options, but they''re intermitten by nature, meaning they''re effective only when the sun is shining and the wind blowing.
When asked to define grid-scale energy storage, it''s important to start by explaining what "grid-scale" means. Grid-scale generally indicates the size and capacity of energy storage and generation facilities, as well as how the battery is used. The size of a battery storage facility is its standard physical dimensions, and the capacity is the amount of electricity the facility can put out and store, measured in kilowatt hours (kWh), megawatt hours (MWh), gigawatt hours (GWh), and at some point in the future terawatt hours (TWh).
Grid-scale is different in terms of battery size and use cases than residential scale or commercial and industrial sale. Here is a breakdown of the differences between the three main levels of energy storage systems:
Today''s systems using lithium-ion batteries are different from those pumped hydro, compressed air, or gravity because they are fast, providing power almost instantly when needed. They are also scalable if there''s a need for expansion. Batteries are also portable, unlike other storage systems that need to be on mountaintops or in underground tunnels.
