CO2 Concrete Curing

Injects captured CO2 into concrete during curing, mineralising it permanently within the building material.

Ocean Alkalinity Enhancement

Increases ocean alkalinity to boost the ocean's natural capacity to absorb and store atmospheric CO2.

Electrochemical Ocean Carbon Removal

Uses electrochemical processes to extract CO2 from seawater, enabling the ocean to absorb more from the atmosphere.

DAC

Mechanically captures CO2 directly from ambient air for storage or utilisation - Direct Air Capture.

In Practice

Purpose-built machinery draws in ambient air and chemically strips out the CO2 it contains.

Captured CO2 is compressed and routed to storage or a utilisation pathway.
Can be sited wherever the storage or utilisation destination makes sense, not tied to a specific source.

The Carbon Case

Removal is direct and precisely measurable - it doesn't depend on land, weather or growing season.

Volume captured is metered at the point of extraction, not modelled or estimated.
Delivers a consistent removal rate independent of season.

The Payoff

Delivers a permanent, engineered removal credit with no reversal risk from fire or land-use change.

Can be sited independent of arable land or specific climate conditions.
Scales by adding capture units rather than requiring new land.

Bioenergy with Carbon Capture and Storage (BECCS)

Combines biomass energy generation with captured and stored CO2, delivering net-negative emissions.

In Practice

Biomass is burned for energy, and the resulting CO2 is captured before it reaches the atmosphere.

Captured CO2 is then routed to permanent geological storage.
Runs alongside existing bioenergy generation rather than as a standalone process.

The Carbon Case

Net-negative, since the biomass already absorbed CO2 while growing and the combustion emissions are then captured too.

Removal volume depends on both biomass carbon uptake and capture efficiency at the plant.
Verified against metered capture rates at the facility.

The Payoff

Generates usable energy and a carbon removal credit from the same process.

Uses existing bioenergy infrastructure rather than requiring an entirely new asset class.
Can be retrofitted onto some existing bioenergy plants.

CCUS

Captures CO2 from industrial point sources for storage or productive use - Carbon Capture, Utilisation and Storage.

In Practice

CO2 is captured directly at an industrial emission source before it's released.

Captured CO2 is then stored geologically or routed to a productive utilisation pathway.
Retrofitted onto the existing industrial process rather than replacing it.

The Carbon Case

Prevents a specific, measurable volume of industrial emissions from reaching the atmosphere at all.

Capture rate is metered continuously against the facility's total emission stream.
Reduction is avoidance-based, tied directly to the source it's captured from.

The Payoff

Lets hard-to-abate industrial processes keep operating while materially cutting their emissions footprint.

Buys time for a sector to transition without requiring an immediate process redesign.
Applicable across cement, steel and chemicals processes alike.

Enhanced Weathering (ERW)

Applies crushed silicate rock to accelerate natural mineral weathering and remove atmospheric CO2.

In Practice

Crushed silicate rock is spread across land, accelerating a mineral weathering process that already occurs in nature.

Application rate and rock type matched to the specific site's soil chemistry.
Deployed across agricultural or industrial land depending on the project.

The Carbon Case

Each tonne of rock applied mineralises a calculable volume of atmospheric CO2 over time.

Removal is verified through soil and water chemistry sampling over the weathering period.
Reaction rate depends on rock type, particle size and local climate.

The Payoff

Delivers soil health improvements to the land it's applied to, alongside the carbon removal.

Can be deployed across land already in active use, without displacing production.
Adds a secondary soil-mineral benefit beyond the carbon credit.

In-situ Mineralisation

Injects CO2 into suitable rock formations, converting it into stable mineral form underground.

In Practice

Captured CO2 is injected into suitable rock formations, where it reacts and converts into solid mineral form.

Injection site selected for rock chemistry known to react readily with CO2.
Delivered as a downstream storage step for CO2 captured elsewhere.

The Carbon Case

Mineralised CO2 is locked away permanently, with essentially no reversal risk once the reaction completes.

Reaction can be monitored to confirm the CO2 has actually converted to stable mineral form.
Storage security improves over time as more CO2 mineralises.

The Payoff

Provides a disposal pathway for captured CO2 that doesn't rely on long-term monitoring of a living system.

Frees up capacity for continued capture once early injection sites reach mineralisation.
Requires less ongoing oversight than storage pathways reliant on containment alone.

Industrial Waste Mineralisation

Uses industrial waste streams such as slag or tailings as a substrate for accelerated CO2 mineralisation.

In Practice

Uses existing industrial waste such as mine tailings or slag as the reactive material for CO2 mineralisation.

Waste material is already crushed and exposed, reducing the processing needed before reaction can begin.
Delivered at the same site the waste is already stockpiled.

The Carbon Case

The waste's existing reactivity makes mineralisation faster and cheaper to achieve than with fresh rock.

Removal volume scales with the quantity of reactive waste material available on site.
Reaction rate benefits from the waste's already-fine particle size.

The Payoff

Turns an existing waste liability into a carbon removal asset, rather than requiring new feedstock.

Can address a legacy waste disposal problem alongside the carbon outcome.
Avoids the cost of sourcing and transporting fresh rock feedstock.

Geologic CO2 Storage

Stores captured CO2 in deep geological formations for long-term containment.

In Practice

Stores captured CO2 in deep geological formations engineered to contain it long-term.

Storage site selected and characterised for long-term containment integrity before injection begins.
Serves as the storage step for capture projects such as DAC, BECCS or CCUS.

The Carbon Case

Provides a high-volume storage pathway for CO2 captured from DAC, BECCS or CCUS projects.

Storage integrity monitored on an ongoing basis after injection.
Capacity assessed against the volume the formation can safely hold.

The Payoff

Makes large-scale capture projects viable by giving them somewhere permanent to put the CO2.

Can serve multiple capture projects from a single storage site.
Unlocks capture project financing by de-risking the storage step.

Bio-oil Geological Storage

Converts biomass into bio-oil and injects it into geological storage, locking away biogenic carbon.

In Practice

Converts biomass into a stable bio-oil, which is then injected into geological storage.

Conversion process designed to stabilise the biomass carbon before it can decompose.
Delivered as an alternative to burning or leaving biomass to decompose.

The Carbon Case

Locks away the biogenic carbon the biomass absorbed while growing, before it can be released again.

Storage volume tracks directly with the quantity of biomass converted and injected.
Verified through metering of bio-oil volume injected.

The Payoff

Turns otherwise low-value biomass waste into a durable carbon storage pathway.

Avoids the emissions that would occur if the biomass were left to decompose or was burned.
Provides an outlet for biomass with no other economic use.

Synthetic Carbon Materials

Converts captured CO2 into durable synthetic materials, storing carbon in a usable product.

In Practice

Chemically converts captured CO2 into durable synthetic materials rather than storing it underground.

Conversion process tailored to the specific end material being produced.
Delivered as a productive-use alternative to geological storage.

The Carbon Case

The carbon stays locked in the material for as long as the product itself exists.

Storage duration depends on the specific material's expected service life.
Verified against the carbon content of the material produced.

The Payoff

Produces a saleable material alongside the carbon storage, offsetting some of the project's cost.

Creates a market-facing product rather than a purely disposal-oriented outcome.
Can improve project economics compared to storage-only pathways.

CO2 Concrete Curing

Injects captured CO2 into concrete during curing, mineralising it permanently within the building material.

In Practice

Injects captured CO2 into concrete during the curing process instead of venting or storing it separately.

Dosing calibrated to the specific concrete mix and curing conditions used.
Delivered directly within existing concrete production.

The Carbon Case

The CO2 mineralises permanently within the concrete itself as it cures.

Mineralisation can improve the concrete's compressive strength alongside storing carbon.
Verified through the CO2 dosage metered during curing.

The Payoff

Uses a material the construction industry already needs at scale, requiring no separate storage infrastructure.

Integrates into existing concrete production lines rather than requiring a new facility.
Adds a performance benefit to the concrete itself.

Ocean Alkalinity Enhancement

Increases ocean alkalinity to boost the ocean's natural capacity to absorb and store atmospheric CO2.

In Practice

Adds alkaline material to seawater, increasing the ocean's chemical capacity to absorb atmospheric CO2.

Dosing and location selected to manage local marine chemistry impact.
Delivered at coastal or open-ocean sites suited to the method.

The Carbon Case

A more alkaline ocean draws down additional CO2 from the atmosphere to restore chemical equilibrium.

Removal volume calculated from the quantity and type of alkaline material added.
Verified through ocean chemistry monitoring at the deployment site.

The Payoff

Taps the ocean's vast natural carbon sink capacity, at a scale land-based approaches can't match.

Doesn't compete with land use the way most terrestrial removal pathways do.
Offers a removal pathway with substantial theoretical scale.

Electrochemical Ocean Carbon Removal

Uses electrochemical processes to extract CO2 from seawater, enabling the ocean to absorb more from the atmosphere.

In Practice

Uses an electrochemical process to extract dissolved CO2 directly from seawater.

Processed seawater is returned to the ocean, where it can absorb more CO2 from the air.
Delivered from shore-based or vessel-based processing units.

The Carbon Case

Directly measurable removal from the ocean-atmosphere system, verified at the point of extraction.

Extraction rate is metered continuously at the processing facility.
Removal is engineered and precisely quantifiable, not modelled.

The Payoff

Offers a precisely engineered, land-independent removal pathway.

Doesn't compete for agricultural land the way many terrestrial approaches do.
Can be scaled by adding processing capacity.
Why this approach

When it makes sense, and what the trade-off is.

Technology-based approaches typically deliver faster, more precisely measurable outcomes, at a higher capital cost. They suit sites and sectors - cement, mining, industrial waste streams - where the physical process itself has to change, not just the land use around it.
