Global Energy Storage Cell Shipments Surpass 460 GWh in H1 2026: Why the Rankings Diverge

<p>InfoLink, SMM and TrendForce agree on the market's rapid growth, but diverge on company rankings and segment definitions.</p><p>A key takeaway is that the three leading research institutions reached highly similar conclusions on the overall size of the same market, while showing systematic differences in company rankings and segment structures. This is essentially not a matter of data errors, but a reflection of the fact that the energy storage cell industry is entering a stage of "multiple statistical methodologies coexisting."</p><p>In the first half of 2026, the global energy storage cell market continued its explosive growth. InfoLink Consulting, Shanghai Metals Market (SMM), and TrendForce EnergyTrend successively released their semi-annual data. The three institutions estimated global shipments at 467.84 GWh, approximately 486 GWh, and more than 460 GWh, respectively, with year-on-year growth remaining between 93% and 95%.</p><p>While the three reports are highly consistent in their assessment of the overall market size, they show significant differences in company rankings, market concentration, and segment classifications. These differences do not necessarily mean that one is "right" and another is "wrong." Instead, they signal something more important: the statistical methodologies used to measure the energy storage cell industry are becoming increasingly complex and difficult to standardize.</p><h2>Consensus Is Emerging: The Market Remains Characterized by Both Rapid Growth and High Concentration</h2><p>From the perspective of overall market trends, the three institutions are highly aligned in their assessment of the industry's fundamentals—the global energy storage cell market remains in a period of rapid expansion.</p><p>According to InfoLink, global shipments reached 467.84 GWh in H1, with a CR5 of 56.5% and a CR10 of 82.3%. TrendForce estimates that the market exceeded 460 GWh, with a CR3 of approximately 44% and a CR10 of approximately 84%. Although SMM did not fully disclose concentration data, it likewise confirmed that the market maintained strong growth.</p><p>Despite differences in specific figures, one common conclusion is clear: the industry is entering a phase in which "scale expansion and increasing concentration" are occurring simultaneously.</p><p>In terms of demand structure, overseas markets have become the core source of incremental growth. European residential storage entered a restocking cycle after the destocking period ended, while large-scale energy storage projects in the Middle East and North America saw concentrated deliveries. New demand also continued to emerge from India, Australia, and the Nordic markets.</p><p>Against this backdrop, the focus of competition among companies is shifting from price toward delivery capabilities, global service capabilities, and supply chain stability.</p><h2>The Essence of the Ranking Divergence: The Fourth Place Onward Has Entered a "Narrow-Difference Competition Zone"</h2><p>In terms of company rankings, the three institutions show a high degree of consistency in the top three: CATL, Hithium, and EVE Energy remain the top three global suppliers.</p><p>CATL ranks first in all three rankings, and TrendForce points out that its shipment volume has exceeded that of the second-ranked company by more than two times, with its lead remaining substantial.</p><p>The real divergence begins from fourth place onward.</p><p>BYD ranks fourth in some rankings and sixth in others, while CALB, Chuangneng New Energy, Great Power, and Envision/AESC-related entities also show fluctuations of one to two positions. Gotion High-Tech and Sunwoda enter or exit the Top 10 in some rankings.</p><p><img src="https://energyplanet.oss-cn-shenzhen.aliyuncs.com/uploads/images/20260820161229_9ac8551f.png" alt="" loading="lazy" decoding="async" /></p><p>The key reason for these differences is not that the competitiveness of these companies has changed dramatically, but rather a more practical characteristic of the industry: the shipment gap among mid-tier companies has narrowed to the scale of a single large project.</p><p>Whether a project is delivered before the statistical cutoff date, whether direct cell shipments or the system integration segment are included, and even whether shipments are recognized across different quarters can directly affect the half-year ranking.</p><p>Therefore, fluctuations between fourth and tenth place are essentially the result of the combined effects of "delivery timing + statistical boundaries," rather than a fundamental change in the competitive landscape.</p><h2>Segment Divergence Is Even Greater: The Issue Is Not the Data, but "How the Market Is Divided"</h2><p>If differences in overall rankings can still be regarded as boundary-related fluctuations, then differences in market segmentation directly stem from the lack of a unified classification system. All three institutions confirm that utility-scale storage remains the absolute backbone of the market, but their classification methods differ significantly:</p><p>• InfoLink: Utility-scale storage cells + small-scale storage cells</p><p>• TrendForce: Utility-scale &amp; C&amp;I energy storage + residential storage</p><p>• SMM: Grid-side + C&amp;I + residential storage</p><p>Under these systems, an important question emerges: InfoLink's "small-scale storage" cannot be directly equated with the "residential storage" categories used by TrendForce and SMM.</p><p>This means that the same market may be divided, combined, or reclassified differently across different research institutions, making direct horizontal comparisons of segment data impossible.</p><p>At the trend level, however, the three institutions still reach the same conclusion: utility-scale storage accounts for the vast majority of shipments, while residential and small-scale storage are becoming the fastest-growing segments.</p><p>In the residential/small-scale storage market, the structural consensus is also clear, but the rankings are not consistent.</p><p>All three institutions rank EVE Energy, Great Power, and REPT BATTERO among the top three global residential storage cell suppliers, with their combined market share generally exceeding 60%.</p><p>However, the specific rankings differ. InfoLink and TrendForce swap the top position, while SMM's structure is closer to that of TrendForce.</p><p>This points to an important fact: the competitive landscape of the residential storage market has become relatively stable, but there is still no unified statistical standard for determining who ranks first.</p><p>The reasons mainly include differences in application definitions, whether communications and small C&amp;I products are included, how overseas channel inventory is recognized, and whether cells are reclassified at the Pack stage.</p><p>In other words, the core question in the residential storage market has shifted from "Who is leading?" to "How should the market boundary be defined?"</p><h2>Methodological Differences: Why Do the Three Institutions Reach Different Conclusions?</h2><p>From a methodological perspective, none of the three institutions relies solely on company disclosures. Instead, all adopt a hybrid approach combining industry research, modeling, and supply chain verification.</p><p>InfoLink relies on industry interviews and model-based estimates, supplementing data for companies that do not disclose figures.</p><p>SMM combines domestic supply chain data, operating rates, and tender information to develop its estimates.</p><p>TrendForce, meanwhile, bases its analysis on a global supply chain database and conducts cross-regional modeling.</p><p>The differences are mainly concentrated in five key areas: shipment recognition points, product scope definitions, company attribution methodologies, whether vertically integrated companies are double-counted, and deviations between model estimates and company disclosures.</p><p>When these factors are combined, the same market can show an approximately 5% difference in total market size and one to three positions of fluctuation in company rankings across different institutions.</p><h2>Surpassing 1 TWh for the Full Year Has Become a Consensus, but the Pace Remains Uncertain</h2><p>Despite differences in statistical methodologies, the three institutions are highly aligned in their outlook for the full year: global energy storage cell shipments are expected to exceed 1 TWh for the first time in 2026. InfoLink forecasts approximately 1,026 GWh for the full year, while TrendForce expects approximately 1,012 GWh, both pointing toward the beginning of the "1,000-GWh era."</p><p>However, it should be noted that H1 data cannot simply be extrapolated linearly to the full year. The second half of the year will still be affected by multiple factors, including overseas policies, project grid-connection schedules, inventory cycles, and the ramp-up of production capacity for large-format cells.</p><h2>Final Thoughts</h2><p>The real divergence is not in the rankings, but in "whether the industry can still be described using a single statistical standard." Overall, the greatest value of the three reports does not lie in providing a single definitive ranking, but in jointly revealing a change that is already underway: <strong>The energy storage cell industry has moved from a "growth stage with relatively standardized data" into a "complex stage characterized by multiple statistical systems."</strong></p><p>At this stage, ranking differences themselves are no longer the core issue. What truly matters is understanding the statistical boundaries behind each set of data. For the industry, what ultimately determines the competitive landscape will no longer be a single quarter's ranking, but global delivery capabilities, product iteration speed, and the ability to consistently fulfill commitments across different market systems.</p><p><br /></p><p><strong>Source:</strong></p><p>InfoLink 🔗: <a href="https://www.infolink-group.com/energy-article/energy-storage-topic-global-battery-shipment-ranking-1h26" target="_blank" rel="noopener noreferrer">https://www.infolink-group.com/energy-article/energy-storage-topic-global-battery-shipment-ranking-1h26</a> </p><p>SMM 🔗: <a href="https://news.metal.com/newscontent/104039629-smm-h1-2026-ess-cell-shipment-rankings-stable-top%E2%80%90tier-landscape-vs-cut%E2%80%90throat-competition-among-second%E2%80%90tier-players" target="_blank" rel="noopener noreferrer">https://news.metal.com/newscontent/104039629-smm-h1-2026-ess-cell-shipment-rankings-stable-top%E2%80%90tier-landscape-vs-cut%E2%80%90throat-competition-among-second%E2%80%90tier-players</a> </p><p>EnergyTrend 🔗: <a href="https://www.energytrend.com/research/20260814-51941.html" target="_blank" rel="noopener noreferrer">https://www.energytrend.com/research/20260814-51941.html</a> </p>
