Compressed Air Energy Storage Modularity Patent Landscape 2026
What this landscape covers
This dataset isolates patent families that combine compressed air energy storage language with modularity terms — modular system, containerized storage, standardized module — inside the claims or description, restricted to IPC codes covering gas-turbine plant components, smart-grid interconnection, and fluid-pressure actuators. That is a narrow cut: 23 published families across roughly a decade of filing activity. The receiving-office spread is thin and international, with no single jurisdiction taking a clear lead.
Publication typically lags filing by around 18 months, so the most recent year in any trend undercounts real filing activity. Read the flat-to-zero recent-year figures with that lag in mind rather than as proof the field has stopped moving.
Filing trend and technology composition
Two views of the same 23-family dataset: how filing activity moved year over year, and which IPC subclasses carry the modularity claims.
Filing trend, 2017–2026
Filings peaked at zero in 2017 and stayed flat through the tracked midpoint of 2022, with the most recent year still partial. There is no visible growth phase in this cut of the data — the flat line reflects either a genuinely quiet sub-field or a search string narrow enough to miss adjacent modular-CAES filings classified outside the chosen IPC codes.
IPC subclass composition
F02C (gas-turbine plants) leads with 19 of the records, followed closely by F01K (steam and thermal power plants) at 15 — many families span both, reflecting hybrid CAES-turbine architectures. F01D and F15B each hold 4 records, and F04B a single one, showing that positive-displacement pumping and fluid actuation are present but marginal to how modularity is currently claimed.
Shares are the percentage of the 23 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Hydraulic actuator for a compressed air energy storage system
A hydraulic actuator adapted to be coupled to one or more pistons of a compressed air energy storage (CAES) system includes a housing forming a plurality of aligned bores, with a shaft disposed therein for reciprocating movement. For a three-bore configuration, the shaft has three pistons subdividing the three bores into six pressure chambers. Four valves fluidically connected to the six chambers selectively provide pressurized hydraulic fluid, permitting three levels of hydraulic shaft force for each direction of shaft motion.Filed by General Compression, Inc. — the actuator claims sit at the mechanical core of several higher-cited adsorption-enhanced CAES records in this dataset.

Citation counts inside a bounded search corpus skew toward older filings that have had more time to accumulate citations — treat them as a measure of influence on this specific cluster, not as a ranking of current commercial importance.
Publication numbers are shown where the record carries one (7 of 7 rows); clicking a row searches Eureka by that number.

Three read-throughs from the trend, composition and citation data above.
A quiet sub-field, not a growing one
The flat trend across the tracked window means claim space here has not been aggressively contested year over year. That can mean genuine white space, or it can mean the modularity language this search targets simply hasn't caught on as a drafting convention yet — worth checking against a broader keyword set before concluding the field is empty.
Modularity is being claimed through turbine hardware
Most families frame modularity as a property of the turbine or thermal-cycle equipment rather than of a standalone storage module or software-defined control layer. A filer targeting containerized or plug-and-play storage architecture independent of turbine design is claiming into comparatively open space.
Adsorption-enhanced CAES anchors the cluster
The most-cited records all describe adsorption-enhanced CAES, and by a wide margin over the next tier. That concentration suggests later filers in this space have consistently had to design around or build upon that adsorption approach rather than an alternative storage medium.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to compressed air energy storage modularity and standardization, with the prior art for and against each one.

The dataset's single strongest co-assignee pair links one organisation to one named inventor across three records — a small, closely held inventive core rather than a distributed multi-company collaboration network.
Where to take this analysis
The dataset points to specific next checks rather than a single conclusion.
Widen the keyword net
A flat trend built on a narrow TACD string may be undercounting filings that use different modularity vocabulary. Re-running with broader synonyms before concluding this is genuinely white space is worth the extra pass.

The three most-cited records all describe adsorption-enhanced CAES. Isolating that sub-cluster and tracing its citation network would clarify whether later filers are designing around it or licensing into it.

The representative hydraulic-actuator record sits at the mechanical core of several higher-cited families. Any new filing on piston or valve configuration in a CAES system should be checked against its claim scope first.

This dataset identifies 23 published patent families matching a search string that combines compressed air energy storage terms with modularity language (modular system, containerized storage, standardized module) inside claims or descriptions, restricted to gas-turbine, smart-grid and fluid-actuator IPC codes. That is a narrow, purpose-built cut rather than a count of all CAES patents generally. Broader CAES searches without the modularity and IPC restrictions would return a substantially larger set.
The tracked filing trend shows zero at the 2017 peak and zero again at the 2022 midpoint, with no visible growth phase across the window. This can reflect genuinely low interest in the specific modularity vocabulary this search targets, or it can reflect that most modular-CAES innovation is being claimed under different terminology or classified into IPC codes outside this search's scope. Publication lag of roughly 18 months also means the very latest year is always undercounted, so recent flatness should not be read as a definitive stop in activity.
F02C, covering gas-turbine plants, carries the largest share of records in this dataset at 19 of 23. F01K, steam and thermal power plants, is close behind at 15, and many families overlap both classes because hybrid CAES-turbine architectures are common. F01D, F15B and F04B are present but marginal, together accounting for a small remainder — a sign that modularity claims are currently anchored to turbine and thermal hardware rather than to standalone storage-module or control architecture.
US20140260948A1, assigned to General Compression, Inc., claims a hydraulic actuator built around a housing with multiple aligned bores and a shaft carrying pistons that subdivide those bores into pressure chambers. In its three-bore configuration, four valves connect to six pressure chambers to deliver three discrete levels of hydraulic shaft force in each direction of motion. Anyone designing a piston-and-valve hydraulic drive for compressing or expanding air in a CAES system should check this claim scope before finalizing a bore-and-valve arrangement, since it sits at the mechanical core of several higher-cited adsorption-enhanced CAES families in this dataset.
Based on the IPC composition in this dataset, the thinnest coverage sits outside gas-turbine and thermal-cycle hardware: standalone containerized storage-vessel modules, grid-interconnection control logic under H02J3/28, protocols for interlinking multiple standardized modules, and fluid-pressure actuation designed independently of a specific turbine architecture. These are inferred from what is absent or lightly represented in the 23-family set, not confirmed as empty by a freedom-to-operate search, so they should be treated as leads for deeper diligence rather than settled conclusions.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
