Blue Hydrogen Advanced Materials Patents: Leaders & White Space 2026
- Filing has already peaked. 2022 recorded 7 of the 16 families in this dataset, and activity has not returned to that level since — a sign the earliest catalyst and sorbent chemistries were staked out early.
- One IPC subclass dominates almost every filing. 15 of 16 records sit in C01B (non-metallic elements & inorganic compounds), meaning the CO2-capture and hydrogen-generation chemistry itself, not adjacent hardware, is where the claim density concentrates.
- No single assignee controls the field. Recent-year momentum for the most active filers shows flat or falling activity — including a 100% year-on-year drop for two of them — pointing to a fragmented, still-open competitive set rather than an entrenched leader.
What this landscape covers
This dataset tracks patent families at the intersection of blue hydrogen production and the advanced materials that make carbon capture practical inside that process: reforming catalysts, water-gas-shift catalysts, and CO2 sorbents. The search combines process-level terms (“steam methane reforming with capture”, “autothermal reforming hydrogen”) with material-level claim language (“reforming catalyst”, “CO2 sorbent”, “catalyst material”), restricted to the IPC classes that cover catalysis, gas separation and inorganic hydrogen chemistry.
Sixteen published families meet these criteria across the 2015-2026 window, a small enough corpus that individual filings move the picture meaningfully. Publication lags filing by roughly 18 months, so the 2026 count in particular understates real filing activity that has not yet published.
Filing trend and technology composition
Two views of the same 16-family dataset: how filing volume has moved year over year, and which IPC subclasses carry the claim weight.
Filing trend, 2017-2026
Filings rose to a peak of 7 families in 2022 and have not matched that level since; the 2017 baseline and 2026 partial-year figure both sit at zero, framing a corpus that built quickly around one peak year rather than climbing steadily.
Technology composition by IPC subclass
C01B (non-metallic elements and inorganic compounds, including hydrogen generation chemistry) accounts for 15 of 16 records — nearly the entire dataset. B01D (separation processes) and B01J (catalysis) each carry 3 records, with single mentions in C01D, F01D, F01K and F17C marking where the technology touches turbines, thermal power plant and gas storage but has not yet been claimed there in depth.
Shares are the percentage of the 16 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Novel hybrid sorbent-catalyst composition and method of making thereof for blue hydrogen production
Filed by the Council of Scientific & Industrial Research, this application claims dual functional materials (DFMs) that combine CO2 sorption and catalytic activity in one particle for sorption-enhanced steam methane reforming. The sorbent is calcium oxide derived from biowaste sources — snail shells, seashells or eggshells — paired with a nickel catalyst from nickel nitrate hexahydrate, prepared by wet mixing, wet impregnation or sol-gel routes.Filed 2026-07-02 — the most recent record in this dataset.

Three findings that change where a team should file next, drawn directly from the trend and composition data above.
The peak has already passed
Filing rose to 7 families in 2022 and has since cooled. For a field this early in commercial deployment, a peak-then-plateau pattern usually means the first wave of obvious material combinations — nickel catalysts, calcium-based sorbents — has already been claimed, and later filers are working narrower variations.
Almost everything sits in one subclass
C01B covers the hydrogen-generation and inorganic-compound chemistry itself. With 15 of 16 records there, the dataset says the fight is over the reaction chemistry and sorbent composition, not over separation hardware or plant integration — those sit at 3 records or fewer.
No filer is compounding its lead
The assignees with the most recent-year activity in this corpus show flat or sharply negative year-on-year change, including two drops of 100%. That is consistent with a field where early filers staked a position and have not followed up, rather than one where a leader is pulling away.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to blue hydrogen advanced materials, with the prior art for and against each one.
Who is active, and where the gaps sit
With only 16 families total, this is a fragmented field: activity is thin enough that receiving-office choice and IPC subclass reveal more about strategy than any single assignee's count does.
Filers are hedging jurisdiction, not concentrating it
Europe (EPO) and WIPO (PCT) each carry 3 records, with AE, Canada, India and the United States at 2 apiece. No single office holds a majority, which suggests filers are still testing where blue hydrogen capacity will actually be built rather than defending one home market.
Recent activity has gone quiet
The assignees with any recent-year filings in this corpus report zero in the latest year — a -100% year-on-year change for two of them. That is a small-sample effect as much as a strategic one, but it means no filer currently has visible filing momentum to react to.
Adjacent hardware is barely claimed
Turbine integration (F01D), thermal power plant design (F01K) and gas storage vessels (F17C) each appear once. These are the points where blue hydrogen materials meet plant equipment, and the claim record there is thin enough to be worth checking before assuming it is occupied.
| Assignee | Recent year | YoY |
|---|---|---|
| Haldor Topsoe | 0 | -100% |
| Council of Scientific & Industrial Research | 0 | -100% |
| L'Air Liquide | 0 | — |
Where to take this analysis
The trend and composition data point to specific next questions rather than a single conclusion.
Check the adjacent hardware classes before assuming they're clear
F01D, F01K and F17C each carry only one record in this dataset. That could mean genuine white space, or it could mean the relevant claims are filed under a different search string entirely — worth a targeted follow-up search before relying on it.
Explore white space in EurekaWatch whether the 2022 peak repeats
A single peak year followed by a decline is a pattern worth revisiting once 2025-2026 filings finish publishing, since the current 2026 figure is necessarily incomplete.

This dataset of 16 patent families does not show a dominant leader. The most recently active assignees — including the Council of Scientific & Industrial Research, which filed the newest record in July 2026 — show flat or declining year-on-year filing activity rather than sustained growth. That makes this a fragmented competitive set where filing position, not incumbency, decides who controls a given chemistry. Anyone assessing freedom to operate should check individual filings rather than assume one company controls the space.
The dataset centres on two material classes: catalysts that drive steam methane reforming or the water-gas-shift reaction, and CO2 sorbents that capture the carbon released during that process. The most recent representative filing combines both in a single dual functional material — a nickel catalyst paired with a calcium oxide sorbent derived from biowaste such as snail shells, seashells or eggshells. Nearly all filings in this corpus (15 of 16) sit in IPC subclass C01B, which covers this reaction and sorbent chemistry directly.
Filing peaked at 7 families in 2022 and has not returned to that level since, based on the 2015-2026 trend in this dataset. That pattern — a single peak followed by a plateau or decline — usually indicates that early, obvious material combinations have already been claimed and later filers are working narrower or more specific variations. The 2026 figure is partial because publication typically lags filing by around 18 months, so recent activity is understated in any trend chart.
The clearest gaps sit outside the dominant C01B chemistry class: turbine-integrated reforming heat recovery (F01D), thermal power plant design (F01K) and gas storage vessel materials (F17C) each carry only a single record in this dataset. Within the core chemistry, sorbent regeneration cycles and dual functional material particle architecture are also thinly claimed relative to the base catalyst and sorbent compositions. These are starting points for a freedom-to-operate search, not confirmed open territory — a targeted search against each subclass is still needed before filing.
WO2026139975A1 claims a process for preparing dual functional materials that combine CO2 sorption and catalytic activity in a single particle, intended for sorption-enhanced steam methane reforming in blue hydrogen production. The sorbent is calcium oxide derived from biowaste sources including snail shells, seashells or eggshells, and the catalyst is nickel sourced from nickel nitrate hexahydrate. The application covers multiple preparation routes — wet mixing, wet impregnation and sol-gel synthesis — which means it likely blocks straightforward combinations of biowaste-derived CaO with nickel catalysts prepared by any of those three methods.

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.
