Patent Landscape · Carbon Capture, Utilization & StorageCarbon Capture, Utilization & Storage Patents: Who Is Filing and Where the Field Is Still Open
- Filing nearly doubled from 2021 to 2024, up 114% (71 to 152 records), with 2023 the peak year so far at 219 records.
- The field is not a single-leader market: the top 5 assignees hold just 21.8% of all 1,163 records, and the top 10 only 31.6% — a long tail does the rest of the filing.
- Separation processes dominate the claim map, with B01D present on 31.6% of records, more than double the next-largest class.

Leading Jurisdiction
Filing growth compares 2021 (71 records) with 2024 (152) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 1,163 records in scope (CR5), not by the ranked leaders only.

Overview
What the CCUS patent record actually shows
Carbon capture, utilization and storage spans a wide set of engineering disciplines: gas separation, well drilling and injection, mineralization chemistry, electrolytic conversion, and combustion-plant retrofits all show up in the same search scope. That breadth means the 1,163 records analysed here are not a single technology race but a set of loosely connected claim territories, each with its own leaders and its own filing pace. Post-combustion capture and geological storage are the two poles most readers have in mind, but the IPC composition shows electrolytic and cement/ceramics routes carrying real filing weight too.
Publication lags filing by roughly 18 months, so the most recent one or two years in any trend understate real activity. The usable signal runs through 2024, where filing volume nearly doubled from three years earlier — a genuine acceleration, not an artefact of the data cut-off.

The Data
Filing trends and technology composition
The numbers below are drawn directly from the 1,163 records in scope: a nine-year filing trend and an IPC subclass breakdown showing where claim density concentrates.
A three-year filing surge, not yet cooling
Annual filings rose from 23 in 2017 to a peak of 219 in 2023, and the 2021-2024 span alone shows +114% growth (71 to 152 records). 2025 and 2026 figures are still filling in behind the publication lag, so the apparent plateau in the latest years is not evidence of a slowdown.
Separation and wellbore classes lead a wide technology spread
B01D (separation processes) touches 31.6% of records, well ahead of C01B (15.6%), E21B well/drilling technology (11.8%) and F02C gas-turbine plants (11.5%). Because records carry multiple IPC classes, these shares sum past 100% — the pattern to read is relative claim density across routes, not a partition of the field.
Shares are the percentage of the 1,163 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the composition and citation data mean for strategy
Three patterns stand out once volume, class distribution and citation weight are read together: a fragmented ownership base, a separation-technology centre of gravity, and an older core of highly-cited prior art that any new filing has to work around.
Ownership concentration
21.8%
top 5 share of 1,163 records
No single owner controls the field
The leading assignee holds 70 records and the top 5 combined reach only 21.8% of all records in scope; the top 10 add up to 31.6%. That leaves the large majority of filings distributed across a long tail of single- and few-filing entrants, which is unusual for a field with this much recent filing growth.
Ranking covers 100 companies, not a top-50 or top-100 cut.
Technology centre of gravity
31.6%
of records touch B01D separation processes
Separation claims are the densest territory
B01D appears on nearly a third of all records, more than double the next class (C01B at 15.6%). A new filing aimed squarely at gas-separation mechanics is entering the most crowded part of the map; adjacent classes like C25B electrolytic conversion (8.2%) and F01K steam plants (8.2%) carry noticeably less density.
IPC shares sum past 100% because records carry multiple classes.
Citation weight
374 citations
on the most-cited record in scope
Influence skews toward older filings
The most-cited record in the dataset, on systemic properties of regulated reaction networks, and the next several most-cited records predate the 2021-2024 filing surge by years. That is expected of citation counts inside any searched corpus — older filings have simply had more time to accumulate citations — and should not be read as a ranking of present-day importance.
Five most-cited records span priority dates from the early 2000s to 2020.
Filing acceleration
+114%
growth 2021 to 2024
Growth is real but the tail end is incomplete
Filings nearly doubled between 2021 and 2024, with 2023 the peak year so far at 219 records. Because publication lags filing by roughly 18 months, 2025 and 2026 counts will continue to rise as more records publish — reading them as a decline would be a data-lag artefact, not a market signal.
2024 is the most recent year treatable as complete.

Who's Filing
A fragmented leaderboard with a few concentrated pockets
The assignee ranking runs 100 companies deep, and even the leader accounts for only 70 of 1,163 records. A handful of co-assignee pairs point to internal group filing patterns rather than external alliances, and recent-year momentum is thin across the board — most tracked leaders show flat or falling counts in the latest year, consistent with the publication lag rather than a genuine pullback.
Leader position
70 records
held by the top-ranked assignee
The largest single filer still holds a small share
Even the top-ranked assignee's 70 records amount to a modest fraction of the 1,163-record field, underscoring how distributed CCUS filing activity is across energy majors, industrial gas companies, universities and newer specialist entrants.
Fifth place holds 31 records; tenth place holds 20.
Co-filing pattern
10 pairs
co-assignee pairs identified
Co-assignments cluster inside corporate groups
The strongest co-assignee pairs link related entities within the same corporate family — a consumer goods group's global and regional IP-holding arms, an energy major and its services subsidiary, a power-systems firm and a named inventor. These read as internal filing structure, not cross-company collaboration.
Strongest pair: 11 shared records.
Recent momentum
-88% YoY
at one tracked assignee
Momentum is cooling across most tracked leaders
Several assignees in the momentum data show zero or declining filings in the latest tracked year, including year-over-year drops as steep as -88% and -100% at specific firms. Given the roughly 18-month publication lag, this likely reflects incomplete recent-year data rather than firms exiting the space.
Latest-year counts should be read as provisional.

What's Next
Where to take this analysis
The dataset points to a field that is still filling in at the edges even as its core separation and wellbore claims get denser. The next steps depend on whether the goal is freedom-to-operate, portfolio benchmarking, or spotting where to file next.
Map freedom-to-operate against the densest classes
B01D separation claims and E21B wellbore claims carry the highest density in this dataset; any new filing there should be checked against the existing claim map before drafting.
Run a freedom-to-operate check in EurekaTrack the long tail, not just the leader
With the top 10 assignees holding only 31.6% of records, competitive monitoring needs to cover single- and few-filing entrants, not just the largest names.

FAQ
Common questions about CCUS patents
No single company dominates this field: the leading assignee in the ranked dataset holds 70 of the 1,163 records in scope, and the top 5 assignees combined reach only 21.8% of all records. The top 10 combined reach 31.6%. That leaves the majority of filings spread across a long tail of smaller filers, including energy majors, industrial gas suppliers, universities and newer specialist entrants, so tracking the field by a handful of names alone will miss most of the activity.
Filing activity grew sharply in recent years: annual records rose from 23 in 2017 to a peak of 219 in 2023, and 2021 to 2024 alone shows growth of 114% (71 to 152 records). Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in any dataset pulled today will still be incomplete, so an apparent flattening at the very end of the trend reflects the data lag rather than a real slowdown.
Separation processes, covered under IPC class B01D, appear on 31.6% of the 1,163 records in scope, making it the densest single technology route in the dataset. Non-metallic inorganic compound chemistry (C01B) and wellbore/drilling technology for storage (E21B) follow at 15.6% and 11.8% respectively. Because a single patent can carry several IPC classes, these figures describe relative claim density across routes rather than a strict partition of the field.
The IPC composition shows several branches with meaningfully lower filing density than separation and wellbore claims, including electrolytic CO2 conversion pathways (C25B, 8.2% of records), steam and thermal power plant integration (F01K, also 8.2%), and cement/ceramics-based carbon mineralization (C04B, 6.7%). Lower density in a class means the claim space is less occupied, not that the underlying technology is immature or commercially weak, so these branches are worth a closer freedom-to-operate look before assuming they are crowded.
Ownership is notably unconcentrated for a field with this much recent filing growth. The ranked assignee list covers 100 companies, and even combined, the top 10 hold only 31.6% of the 1,163 total records. This pattern, a fragmented base with a modest leading cluster, suggests competitive dynamics are still being set rather than locked in by a small number of dominant portfolios.
