Compressed Air Energy Storage Design Optimization Patent Landscape 2026
- One family covers this exact intersection. the search string combining CAES with thermodynamic optimization, system sizing, cavern design and expander design IPC codes returns a single published record.
- Filing activity is flat at zero. the trend from 2017 through 2026 shows no year with a filing under this precise claim combination, including the peak year.
- The one record straddles two IPC subclasses. F02C (gas-turbine plants) and H02J (power supply & grid systems), pointing to where any future filing would need to sit.
A narrow, largely unclaimed intersection
Searching for compressed air energy storage design-optimization language against IPC classes for gas-turbine plants, fluid-power systems and grid power supply turns up one published family. That is a signal in itself: the broader CAES field is active elsewhere, but the specific combination of thermodynamic optimization, cavern design and expander design claim language is not where most filers have chosen to compete. The single representative record, WO2013152285A1, filed by CHAMISA ENERGY COMPANY, LLC, describes a multi-cavern architecture with a shared compressor, generator, combustion chamber and recuperator piping network.
With one family and a flat trend, this dataset should be read as a scope check rather than a competitive map. It tells a filer or diligence team what has already been staked out at this narrow intersection, not what the wider CAES patent landscape looks like.

Filing trend and technology split
Two views of the same single-family dataset: how filings moved over time, and which IPC subclasses the record touches.
Filing trend, 2017–2026
Filings under this exact claim combination sat at zero in 2017, the peak year so far, and remained at zero through the 2022 midpoint and into the partial 2026 count. Publication lags filing by roughly 18 months, so the most recent year understates true activity, but a flat line across the full window means this is not a data-lag artefact alone.
IPC composition
The one record classifies under F02C (gas-turbine plants) and H02J (power supply & grid systems), reflecting a design that couples a combustion-assisted expander path with grid-facing power delivery rather than a pure mechanical-storage claim.
Shares are the percentage of the 1 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Multiple cavern compressed air energy storage system and method
An energy system for storing pressurized air and utilizing the pressurized air to generate electricity includes a first storage cavern, a second storage cavern, an air compressor in fluid communication with the first and second storage caverns, an electric generating mechanism, a combustion chamber, a controller and a recuperator. The air compressor is in fluid communication with a compressor piping system, the electric generating mechanism and the combustion chamber are in fluid communication with a generator piping system, and the recuperator is in fluid communication with an exhaust piping system and the generator piping system. The controller is configured to operate the energy system such that stored air can be drawn from either cavern independently.Abstract shown as filed; number, assignee and date are rendered above.

Citation count reflects influence inside this searched corpus, not current commercial relevance — older filings accumulate citations simply by being available longer.

With a single published record, the useful reading is structural: what the claim covers, what subclasses it touches, and what the absence of a filing wave implies.
A single occupant, not an empty field
One family sits at the exact intersection of CAES and design-optimization claim language. That does not mean CAES itself is unclaimed elsewhere — it means this narrow combination of terms and IPC codes has one entrant on record.
No filing wave to react to
The trend line is flat across the full ten-year window, including the 2022 midpoint. There is no growth curve here to time an entry against — the record predates the window and nothing has followed it under this exact claim scope.
Combustion-turbine and grid claims, side by side
The one record spans gas-turbine plant classification and grid power-supply classification, which tells a filer that a combustion-assisted expander design tied to grid delivery is the shape already on file — a purely adiabatic, non-combustion architecture would sit outside this claim's core.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to compressed air energy storage design optimization, with the prior art for and against each one.
Who holds ground here
One assignee appears in this dataset. Recent-year momentum confirms there is no active filer pushing new claims into this specific combination right now.
CHAMISA ENERGY COMPANY, LLC
Holds the sole representative family, a multi-cavern CAES system with shared compressor, generator, combustion chamber and recuperator piping, filed via PCT (WIPO) and published 2013-10-10.
PCT filing, no visible national-phase cluster in this dataset
The single record entered via the PCT route. This dataset does not surface a national-phase filing pattern to assess jurisdictional strategy beyond the international application.
No active filing programme detected
CHAMISA ENERGY COMPANY's latest-year count is zero, meaning this dataset shows no ongoing claim-building activity to monitor at this specific intersection today.

How to use a thin dataset like this one
A single-family result is itself informative, provided the next steps match that reality.

Within this specific search — CAES combined with thermodynamic optimization, system sizing, cavern design or expander design claim language, restricted to a small set of IPC codes — only one published family surfaces. That is not a statement about CAES patents in general, which is a much larger field; it is a statement about this narrow claim intersection. Broader searches without the design-optimization claim terms would return substantially more results.
The representative record in this dataset, WO2013152285A1, is assigned to CHAMISA ENERGY COMPANY, LLC and was published on 2013-10-10. It describes a multi-cavern system with a shared compressor, electric generating mechanism, combustion chamber, controller and recuperator, allowing air to be drawn independently from either cavern. No other assignee appears in this specific dataset.
Under this exact claim combination, no — the filing trend is flat at zero from 2017 through the 2022 midpoint and into 2026, with the identified peak year also at zero filings beyond the one legacy record. Publication typically lags filing by around 18 months, so the very latest year is always undercounted, but a flat line across the full decade is not explained by lag alone. Readers should treat this as evidence of low activity in this narrow slice, not stagnation in CAES technology broadly.
Based on its abstract, the patent claims an energy system with two storage caverns, a compressor connected to both via a compressor piping system, a generating mechanism and combustion chamber connected via a generator piping system, and a recuperator connected to an exhaust piping system and the generator piping system. A controller operates the system so stored air can be drawn from either cavern independently. Anyone designing a multi-cavern CAES architecture with combustion-assisted generation should review the full claim set, not just this summary, before finalising a design.
Based on the IPC split in this dataset (F02C gas-turbine plants and H02J grid power supply), the one existing claim centres on a combustion-assisted, multi-cavern architecture tied to grid delivery. That leaves non-combustion adiabatic expander cycles, independent cavern-draw control logic beyond what is claimed, and cavern-sizing models explicitly tied to grid-dispatch signals as areas worth checking for filing room. Any white-space conclusion should be verified with a broader search, since this dataset is intentionally narrow.

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.
