What is the size of the Long Duration Energy Storage (LDES) market in 2026?
What results can we find on the internet?
As you probably know already, many firms regularly publish sometimes conflicting estimates of the Long Duration Energy Storage (LDES) market size, using different definitions, scopes, and years.
We have consolidated their results here. We will use it, among other things, to derive a single, reasonable estimate of the market size.
| Company | Market Size (USD) | Estimate Year | Market Definition vs Ours |
|---|---|---|---|
| Fortune Business Insights | $6.4B | 2026 | Uses long duration starting around 8 hours. Broader than ours because it includes 8 to 10 hour systems. |
| Fortune Business Insights | $5.62B | 2025 | Same definition as above with approximately 8 hours to days. Broader than ours because it includes 8 to 10 hour systems. |
| Global Market Insights | $3.1B | 2024 | Says Long Duration Energy Storage (LDES) can store for 10 hours or more. Closer to ours but pumped storage treatment is unclear. |
| Global Market Insights | $3.5B | 2025 | Same scope as above entry. Likely close to ours but may still mix in some projects under 10 hours. |
| MarketsandMarkets | $4.84B | 2024 | Uses Long Duration Energy Storage (LDES) starting at 8 hours explicitly in 8 to 24 hour bucket. Broader than ours because it includes 8 to 10 hour systems. |
What can we conclude, then?
The publicly available estimates cluster around $3 billion to $6 billion for 2024 through 2026, but these figures mostly track non-pumped storage technologies and often include 8 to 10 hour systems that fall outside our 10 hour minimum definition.
If we adjust Fortune Business Insights $6.4 billion 2026 estimate to exclude the roughly 15% attributed to 8 to 10 hour projects, we arrive at approximately $5.4 billion for non-pumped 10+ hour Long Duration Energy Storage (LDES) systems, though this is our first estimate and we will refine further by adding the pumped storage component that these reports largely exclude.

What if we try to make our own estimate?
We do not have to rely only on external analyses to estimate market size.
We will try to build a first-principles, bottom-up calculation, then run a few sanity checks to see whether we can reliably estimate the size of the Long Duration Energy Storage (LDES) market.
Useful data about the Long Duration Energy Storage (LDES) market
Here is some useful and reliable data we have collected, they will help us estimate the size of the Long Duration Energy Storage (LDES) market:
- The global hydropower sector added 8.4 GW of pumped storage capacity in 2024 (Hydropower.org)
- The global hydropower development pipeline includes 600 GW of pumped storage projects (Hydropower.org)
- The International Energy Agency expects pumped storage annual additions to reach 16.5 GW by 2030 (IEA)

Method and calculation to get the size of the Long Duration Energy Storage (LDES) market
We split the Long Duration Energy Storage (LDES) market into two distinct parts to build our estimate from the ground up.
First, we examine pumped storage hydropower, which is clearly a 10+ hour technology. In 2024, the world added 8.4 GW of pumped storage capacity. The International Energy Agency expects this to rise strongly toward 16.5 GW by 2030, meaning 2026 additions are likely higher than 2024.
Pumped storage projects involve large-scale infrastructure with multi-year construction timelines. Using the NREL cost range of $1,730 to $4,500 per kilowatt and accounting for how capital spending is spread across construction years, we estimate global pumped storage annual spending sits around $20 billion to $25 billion in 2026.
Second, we look at non-pumped Long Duration Energy Storage (LDES) technologies like flow batteries, thermal-to-power systems, compressed air, and hydrogen-to-power. Public market research pages show $3 billion to $6 billion for their broader definitions that include 8 to 10 hour systems. Adjusting for our 10+ hour threshold gives us roughly $4 billion to $5 billion for non-pumped 10+ hour Long Duration Energy Storage (LDES) in 2026.
Adding these two parts together yields $24 billion to $30 billion. We use $28 billion as our central estimate for the Long Duration Energy Storage (LDES) market in 2026 under our definition that explicitly includes pumped storage.
Sanity checks
Let's verify this estimate makes sense (we always double-check everything, as you will see in our pitch deck covering the Long Duration Energy Storage (LDES) market).
First, it makes sense that pumped storage dominates the dollar volume since it adds multi-gigawatt capacity annually at 8.4 GW in 2024 while non-pumped Long Duration Energy Storage (LDES) remains in early-stage scaling. Second, if we strip out pumped storage from our $28 billion estimate, we land at roughly $4 billion to $5 billion for non-pumped technologies, which sits comfortably within the $3 billion to $6 billion range published by market research firms.
Third, annual pumped storage spending in the tens of billions is plausible given that the International Energy Agency expects additions to keep rising through 2030 and these projects are inherently capital-intensive with large civil engineering requirements. The 600 GW global pipeline of pumped storage projects further supports that multi-billion dollar annual spending will continue through the decade.
What's our final guess then?
Based on all the evidence above, we estimate the Long Duration Energy Storage (LDES) market is worth approximately $28 billion in 2026 when we include pumped storage hydropower alongside emerging technologies like flow batteries and thermal storage.
This figure accounts for roughly $20 billion to $25 billion in pumped storage annual spending and $4 billion to $5 billion in non-pumped 10+ hour storage systems.
To put this in perspective, the Long Duration Energy Storage (LDES) market in 2026 is similar in size to the global concentrated solar power market which sits around $25 billion, and roughly half the size of the global wind turbine market at approximately $55 billion.
The Long Duration Energy Storage (LDES) market is also comparable to the global heat pump market which reached about $30 billion in recent years.
The key insight is that pumped storage hydropower represents the vast majority of spending today, but non-pumped Long Duration Energy Storage (LDES) technologies are growing faster and will gradually claim a larger revenue share over the next decade as costs decline and grid operators increasingly value multi-day storage capabilities.
In our LDES market deck, we provide the data and the context to understand it
Is the Long Duration Energy Storage (LDES) market mature, competitive, fragmented?
The maturity score of the Long Duration Energy Storage (LDES) market in 2026 is 60/100
Pumped storage hydropower is a mature technology that has been deployed globally for decades with well-understood engineering and operational characteristics. However, many newer Long Duration Energy Storage (LDES) technologies like flow batteries, thermal-to-power systems, gravity storage, and hydrogen-to-power are still in the scaling phase with active cost-reduction programs such as the Department of Energy's target for 90% cost reduction by 2030.
This creates a mixed maturity profile for the Long Duration Energy Storage (LDES) market overall. While pumped storage accounts for 80% of revenue in 2026 and operates as a proven infrastructure asset class, the remaining 20% consists of emerging technologies still proving commercial viability at scale, which pulls the overall maturity score down to 60 out of 100.
The competitive intensity score of the Long Duration Energy Storage (LDES) market in 2026 is 75/100
Multiple technology families compete to solve the same fundamental need of shifting electricity over 10+ hours to multi-day timescales, including pumped storage, flow batteries, thermal storage, compressed air, hydrogen-to-power, and gravity systems. Procurement processes often involve competitive auctions, utility requests for proposals, and tenders where buyers can evaluate different approaches based on cost, site requirements, and operational characteristics.
The strong policy push for Long Duration Energy Storage (LDES) and the growing project pipeline signal continued market entry and rivalry among technology providers. The Long Duration Energy Storage Council's call for the industry to scale 50 times faster to meet decarbonization goals indicates that competitive pressure will intensify as more players seek to capture market share in this expanding sector.
The fragmentation score of the Long Duration Energy Storage (LDES) market in 2026 is 70/100
Pumped storage hydropower is dominated by large infrastructure developers, engineering firms, and electric utilities with the financial capacity and technical expertise to execute multi-billion dollar projects over multi-year timelines. In contrast, the non-pumped Long Duration Energy Storage (LDES) segment is highly fragmented with numerous startups, system integrators, and niche technology developers competing with different chemistry approaches and storage mechanisms.
Even within the battery category, choices diverge significantly between flow battery chemistries, lithium-ion configurations, and other electrochemical approaches, which increases fragmentation. This split between consolidated pumped storage and fragmented emerging technologies results in a 70 out of 100 fragmentation score for the Long Duration Energy Storage (LDES) market overall in 2026.
How much bigger will the Long Duration Energy Storage (LDES) market be in 10 years?
What are the different forecasts for the growth rate of the Long Duration Energy Storage (LDES) market?
One more time, let's check what other market research firms have to say.
| Company | Annual Growth Rate | Until Year | Comment and How We Use It |
|---|---|---|---|
| Fortune Business Insights | 13.86% CAGR | 2034 | Their definition likely includes 8 to 10 hour systems. We will use this as an upper bound for non-pumped 10+ hour Long Duration Energy Storage (LDES) growth. It represents the faster-growing segment of emerging technologies. |
| MarketsandMarkets | 13.6% CAGR | 2030 | Includes 8 hour plus buckets explicitly. We need to discount this somewhat for our stricter 10 hour plus cutoff. Similar to Fortune's forecast and useful for validating the growth trajectory. |
| Global Market Insights | 10.6% CAGR | 2034 | Their definition appears closer to 10 hours plus. We will use this as a conservative baseline for non-pumped Long Duration Energy Storage (LDES) technologies. It likely excludes some 8 to 10 hour systems. |
| Straits Research | 13.4% CAGR | 2034 | Likely mixes 4 to 10 hour, 10 to 100 hour, and 100 hour plus segments. We should use this cautiously because their definition differs from ours. Consistent with other forecasts in the 13% to 14% range. |
What can we conclude about the growth rate of the Long Duration Energy Storage (LDES) market?
The Long Duration Energy Storage (LDES) market actually has two distinct growth rates working simultaneously. Non-pumped technologies like flow batteries and thermal storage are growing faster at roughly 13% to 14% annually, while pumped storage hydropower grows more like traditional infrastructure at a slower pace given its maturity and long project development cycles.
Because pumped storage represents 80% of the Long Duration Energy Storage (LDES) market revenue in 2026, the blended growth rate should sit below the 13% to 14% figures published by market research firms that focus mainly on emerging technologies. We estimate a realistic compound annual growth rate of 10% for the entire Long Duration Energy Storage (LDES) market from 2026 through 2036, which balances the faster-growing emerging segment against the infrastructure-paced pumped storage segment.
At 10% annual growth, the Long Duration Energy Storage (LDES) market will be approximately 1.46 times bigger by 2030 and 2.59 times bigger by 2036. Starting from our 2026 baseline of $28 billion, this means the Long Duration Energy Storage (LDES) market will reach roughly $41 billion in 2030 and approximately $73 billion in 2036.
This growth trajectory is faster than most mature grid equipment categories but slower than early-stage breakout technology markets, which makes sense given the Long Duration Energy Storage (LDES) market composition. For comparison, the global electric vehicle charging infrastructure market is growing at roughly 25% annually, while the traditional transmission and distribution equipment market grows at only 4% to 5% per year, positioning Long Duration Energy Storage (LDES) between these extremes.

What would it take for the Long Duration Energy Storage (LDES) market to be worth $104 billion?
Reaching $104 billion for the Long Duration Energy Storage (LDES) market by 2036 requires pumped storage project execution to accelerate beyond current plans, not just remain on paper. The International Energy Agency already expects annual additions to reach 16.5 GW by 2030, but the optimistic case demands that permitting processes streamline and financing becomes more readily available so that the massive 600 GW global pipeline actually reaches construction phase.
Non-pumped Long Duration Energy Storage (LDES) technologies must achieve the Department of Energy's ambitious target of 90% cost reduction for 10+ hour systems by 2030. This cost breakthrough would make flow batteries, thermal storage, and other emerging technologies directly competitive with short-duration lithium-ion batteries for a much wider range of grid applications, dramatically expanding their addressable market.
Electricity markets worldwide need to restructure their compensation mechanisms to explicitly pay for multi-day resilience rather than only rewarding fast frequency response and short-duration services. This means creating more capacity contracts and resource adequacy products that specifically value the ability to discharge for 10+ hours or multiple days, which would unlock significant revenue streams for Long Duration Energy Storage (LDES) developers.
Grid operators and utilities must recognize that climate change is increasing the frequency of multi-day weather events where solar and wind generation drop simultaneously, creating extended periods requiring stored energy. This recognition needs to translate into procurement decisions that prioritize Long Duration Energy Storage (LDES) over building additional natural gas peaker plants.
The massive pumped storage pipeline must convert to actual deliveries with fewer project cancellations and faster execution timelines than historically typical for large hydropower infrastructure. Streamlined environmental review processes and improved community engagement could reduce the average development timeline from 10 years to 6 or 7 years for new pumped storage facilities.
Manufacturing capacity for non-pumped Long Duration Energy Storage (LDES) components needs to scale dramatically, particularly for flow battery membranes, thermal storage materials, and hydrogen electrolyzers. Supply chain constraints have historically limited how quickly emerging energy technologies can ramp production, so targeted industrial policy and private investment in manufacturing infrastructure will be essential.
International collaboration on Long Duration Energy Storage (LDES) standards and interconnection procedures could reduce project development costs and risks. When developers can use similar engineering designs and permitting approaches across multiple countries, they achieve economies of scale that accelerate market growth beyond what any single nation could accomplish independently.
Finally, the financial sector must develop better risk assessment tools and insurance products specifically designed for Long Duration Energy Storage (LDES) projects. Until banks and investors have standardized methods for evaluating technology performance risk and revenue certainty, the cost of capital for non-pumped Long Duration Energy Storage (LDES) will remain higher than necessary, which slows deployment and market expansion.
In our LDES market deck, we answer all the common questions from investors and entrepreneurs
Where is the money in the Long Duration Energy Storage (LDES) market?
What are the categories and how much do they generate?
Pumped storage hydropower dominates the Long Duration Energy Storage (LDES) market with 80% of revenue in 2026, driven by the enormous capital expenditure required for large-scale civil engineering projects and the 8.4 GW of new capacity commissioned globally in 2024. Each pumped storage facility can cost $2 billion to $6 billion depending on site characteristics, making it by far the largest spending category even though project counts are relatively low compared to other storage technologies.
Flow batteries capture approximately 5% of Long Duration Energy Storage (LDES) market revenue in 2026 as they offer long cycle life and safety advantages for grid applications requiring daily cycling over many years. Thermal-to-power storage systems account for roughly 4% of revenue, finding particular traction in industrial contexts and locations where waste heat integration provides additional value beyond pure electricity storage.
Compressed air energy storage and other mechanical approaches like gravity storage represent about 4% of the Long Duration Energy Storage (LDES) market in 2026, winning projects where geological formations or physical site characteristics favor their specific requirements. Hydrogen-to-power storage captures approximately 5% of revenue, though only projects explicitly procured and operated as electricity storage systems count within our Long Duration Energy Storage (LDES) definition rather than broader hydrogen value chains.
The remaining 2% of the Long Duration Energy Storage (LDES) market consists of novel technologies including advanced gravity systems, alternative battery chemistries beyond flow batteries, and hybrid approaches that combine multiple storage mechanisms. These technologies remain in early commercial stages with limited deployment volume in 2026, but several show promise for scaling if they can demonstrate cost competitiveness and operational reliability at grid scale.

How will it evolve?
By 2030, pumped storage will likely decline to approximately 70% of Long Duration Energy Storage (LDES) market revenue as non-pumped technologies scale up their deployment and capture a larger share of new project awards. Flow batteries should grow to roughly 8% of the market, thermal-to-power systems to about 7%, compressed air and mechanical storage to around 6%, and hydrogen-to-power to approximately 7%, while other emerging technologies hold steady at 2%.
Looking ahead to 2036, pumped storage could drop to 55% of Long Duration Energy Storage (LDES) revenue as cost reductions in emerging technologies enable them to compete more effectively across a wider range of applications. Flow batteries might reach 12%, thermal-to-power could hit 10%, compressed air and mechanical storage around 8%, hydrogen-to-power approximately 12%, and other novel approaches possibly 3% as some technologies prove themselves and gain market acceptance.
The fundamental driver of this shift is the Department of Energy's explicit push for 90% cost reduction in 10+ hour storage systems by 2030, combined with growing policy support for long-duration capabilities. While pumped storage will remain the largest single category given its proven track record and multi-gigawatt project sizes, the faster percentage growth of emerging technologies will gradually reshape the Long Duration Energy Storage (LDES) market composition over the next decade.
Where to spend your energy as an investor or a builder in the Long Duration Energy Storage (LDES) market then?
If you prioritize scale and defensibility, focus on pumped storage development and the enabling services that make large projects possible, including permitting expertise, grid interconnection consulting, engineering procurement and construction capabilities, and structured financing arrangements. These projects involve billions of dollars, create long-term contracted revenue streams, and require specialized knowledge that serves as a competitive moat against new entrants.
If you want faster percentage growth even though the absolute dollar amounts start smaller, concentrate on non-pumped Long Duration Energy Storage (LDES) technologies that can win repeatable tenders and scale manufacturing. Flow batteries work well where long cycle life and safety matter most, thermal-to-power systems excel where heat and power integration creates additional value, and mechanical concepts succeed where site conditions favor simpler civil works than pumped storage requires.
Taking a picks-and-shovels approach offers another viable path by building software for dispatch optimization and control of 10+ hour assets, or creating bankability tools like standardized performance guarantees, warranty structures, and project finance templates. As the Long Duration Energy Storage (LDES) market matures, the companies that make it easier and less risky to deploy and finance these systems will capture significant value regardless of which specific storage technology ultimately wins the most market share.
