Permanent atmospheric carbon removal

Carbon removal.
Built to multiply.

AIR-ROCK is engineering a radically simple mineral carbon-removal platform: move ordinary air across reactive alkaline material, lock CO₂ into stable carbonate, then replicate the hardware at industrial scale.

AIR-ROCK is an early-stage technology under development. Performance figures on this site that are labelled targets or projections are forward-looking engineering goals, not measured AIR-ROCK production.

The AIR-ROCK thesis

Make the machine cheap enough that scale becomes repetition.

Most carbon-removal systems chase a bigger plant. AIR-ROCK is taking the opposite route: simple modules, inexpensive mineral feedstocks, ultra-low-pressure airflow and continuous chemistry optimisation.

01

Capture from ordinary air

Outdoor air is pulled through a low-pressure contactor containing reactive alkaline mineral media.

02

Lock it into rock

CO₂ reacts with calcium- and magnesium-bearing material to form stable solid carbonates.

03

Replicate, don’t overbuild

Standardised AIR-BRICK modules are intended to be copied by the hundred or thousand rather than replaced by one complex plant.

The hardware is intentionally boring.

The value is in what passes through the cartridge, not in an expensive steel box. The launch chassis is designed around a cheap frame, removable mineral cartridge, simple moisture control and a fan.

Chemistry-agnostic removable UC-16 media cartridge.
Low-pressure air path designed to keep fan energy small.
Launch hardware can evolve without replacing the whole installed base.
Designed for outdoor industrial sites with simple rain protection.
Post-optimisation engineering target
2.5–5 tCO₂ / year

per AIR-BRICK, after the R&D programme optimises feedstock, moisture, particle size, geometry and operating strategy.

This is a design target based on first-principles airflow modelling and published mineralisation science. AIR-ROCK has not yet measured this output in its own hardware.
Renewable-powered scale-up

Low-energy hardware designed to pair with renewables.

AIR-ROCK's scale-up architecture is designed around very low electrical demand, with production sites planned to combine rooftop solar, wind where appropriate, and grid electricity during build-out and balancing.

Large rooftop solar on permanent production sites.
Wind generation where site planning and resource support it.
Grid power used during commissioning, build-out and renewable shortfalls.
Measured site data will determine the renewable share of delivered removals.
Design principle
Low energy

Every watt avoided improves both carbon-removal economics and net-removal accounting.

This describes AIR-ROCK's planned deployment architecture. It is not a claim that current development hardware is already powered by renewable electricity.

Founders 1,000 is intended as a forward purchase of future independently verified carbon removal, subject to contract. These are not currently issued carbon credits and no removal may be claimed by a buyer until delivery and verification. *Proposed preference: 15% below then-current AIR-ROCK list price for 5 years, capped at 5× the original founding allocation, subject to final contract.
Why now

The pathway already exists. The engineering is the opportunity.

Published work has demonstrated atmospheric carbonation of cementitious material. Frontier is actively funding surficial mineralisation R&D, and Isometric maintains an open-system mineralisation protocol that includes waste cement and demolition waste as potentially applicable feedstocks.

Published science
Natural-air carbonation

A 2023 Journal of Advanced Concrete Technology study reported 11.75 g CO₂ per 100 g of hydrated cement paste after 120 hours in a wet natural-air carbonation setup.

Isometric protocol

Open-system ex-situ mineralisation via Enhanced Air Capture already has a protocol framework, including waste cement and demolition waste among applicable feedstock categories.
