Hydroxyl dispersal delivers rapid climate and air‑quality benefits while CO₂ removal secures long‑term stability. Hydroxyl radicals (OH) are the atmosphere’s primary oxidant; when generated and dispersed locally, they accelerate the breakdown of methane and other short‑lived climate forcers, producing measurable reductions in radiative forcing within years. By contrast, removing the same mass of CO₂ yields durable, permanent benefit but changes global temperatures on decadal to centennial timescales. That difference makes OH‑driven approaches uniquely valuable as a near‑term lever: they will critically lower peak warming risk, reduce surface ozone and harmful pollutants, andbuy significant time (at scale -of 35% of needed cooling), allowing for large‑scale CO₂ removal to scale. ReductionTech pairs rapid OH‑based atmospheric restoration with permanent CO₂‑to‑materials conversion, delivering immediate climate relief and a durable pathway to net‑zero. Can we afford to be without the hydroxyl lever; likely not, given record CO2 levels in 2026 and beyond. In our pilot work, we will evaluate whether and characterize how our hydroxyl is catalytically accelerating GHG removal, if it is, this is the holy grail of non-CO₂ GHG solutions.

Technology Design and Operational Controls

• Membrane generator: low‑moving‑parts membrane module converts oxygen in feed air or CO₂ streams into controlled OH· flux using catalytic surfaces, modest heating, and low pressure.
• Modularity: units are containerized and networkable for airshed coverage or facility scaling.
• Tunable output: real‑time control adjusts OH· generation to meteorology, ambient pollutant loads, and regulatory thresholds.
• Monitoring: redundant sensors for CO₂, CH₄, N₂O, O₃, NOx, PM, temperature, humidity, and flow; mass‑flow meters record product streams.
• Meteorological gating: continuous local meteorology and dispersion modeling determine safe generation windows; operations pause under inversion or poor dispersion.
• Automated safety: hard interlocks trigger throttling or shutdown if ozone, NOx, PM, or other thresholds are exceeded.
• Operator oversight: trained technicians supervise controls, maintenance, and QA/QC; MSDS for OH· and site‑specific EHS procedures are provided.

Verification, Safety and Environmental Assurance

• MRV: baseline monitoring, continuous telemetry, tamper‑evident logs, and chain‑of‑custody for samples support third‑party verification.
• Secondary pollutant prevention: catalyst selection, thermal windows, and control logic minimize ozone and NOx formation; continuous ambient monitoring ensures no adverse air‑quality impacts.
• Product characterization: solids are sampled and analyzed to confirm inertness and stability before reuse or storage.
• Pilot validation: Kamloops pilot provides peer‑reviewed operational data; the CO₂ Crusher pilot scales capture‑to‑solid pathways with independent verification packages.

Practical Outcome

When operated within conservative and more ideal control envelopes, the combined membrane OH· generator and CO₂ Crusher accelerate removal of methane, VOCs, and other reactive gases, address many synthetic GHGs via oxidation or catalytic decomposition, and convert captured carbon into a durable, verifiable solid. Continuous monitoring, meteorological gating, and conservative operational limits ensure pollutant removal without creating secondary air‑quality harms, delivering a safe, scalable pathway for measurable climate impact.

Overview

ReductionTech’s platform pairs a membrane‑based Hydroxyl Emitter with a catalytic CO₂ Crusher to accelerate removal of short‑lived greenhouse gases, short‑lived climate pollutants, and a range of synthetic GHGs while converting captured carbon into a stable, tetrahedral amorphous, diamond‑like solid. Both systems are modular, low‑maintenance, and can operate independently or in parallel. They accept ambient air or waste CO₂ feed and use catalysts, controlled heat, and low pressure to generate hydroxyl radicals and to drive CO₂ cleavage and stabilization. Continuous monitoring, meteorological gating, and automated controls ensure safe operation, prevent secondary air‑quality impacts, and produce verifiable MRV datasets.

Hydroxyl radical chemistry and targeted reaction pathways

The hydroxyl radical OH· is the troposphere’s primary oxidant and initiates rapid oxidation chains that convert many climate‑active species into less potent or more readily removed products. In a controlled, localized emitter, OH· fluxes are tuned to maximize removal while minimizing secondary chemistry.

Methane oxidation sequence

$$\mathrm{C}{\mathrm{H}}_4+\mathrm{O}\mathrm{H}\to \mathrm{C}{\mathrm{H}}_3\cdot +{\mathrm{H}}_2\mathrm{O}$$

$$\mathrm{C}{\mathrm{H}}_3\cdot +{\mathrm{O}}_2+\mathrm{M}\to \mathrm{C}{\mathrm{H}}_3{\mathrm{O}}_2\cdot +\mathrm{M}$$

$$\mathrm{C}{\mathrm{H}}_3{\mathrm{O}}_2\cdot +\mathrm{N}\mathrm{O}\to \mathrm{C}{\mathrm{H}}_3\mathrm{O}\cdot +\mathrm{N}{\mathrm{O}}_2$$

$$\mathrm{C}{\mathrm{H}}_3\mathrm{O}\cdot \to \mathrm{H}\mathrm{C}\mathrm{H}\mathrm{O}\to \mathrm{C}\mathrm{O}\to \mathrm{C}{\mathrm{O}}_2$$

Net effect: stepwise oxidation shortens methane’s atmospheric lifetime and reduces near‑term warming.

VOCs and carbon monoxide

$$\mathrm{R}\mathrm{H}+\mathrm{O}\mathrm{H}\to \mathrm{R}\cdot +{\mathrm{H}}_2\mathrm{O}$$

$$\mathrm{C}\mathrm{O}+\mathrm{O}\mathrm{H}\to \mathrm{C}{\mathrm{O}}_2+\mathrm{H}\cdot$$

OH· converts VOCs and CO into oxygenated intermediates that partition to particles or are removed by deposition, lowering ozone precursors and improving air quality.

Synthetic GHGs including HFCs CFCs PFCs and SF₆

• Partially fluorinated species and many HFCs undergo hydrogen abstraction by OH·:

$$\mathrm{R}\text{\hspace{0.17em}⁣}-\text{\hspace{0.17em}⁣}\mathrm{H}+\mathrm{O}\mathrm{H}\to \mathrm{R}\cdot +{\mathrm{H}}_2\mathrm{O}$$

Subsequent radical chemistry leads to fragmentation and oxidation, progressively degrading the molecule.

• Chlorofluorocarbons CFCs and some PFCs are more resistant but can be gradually degraded under elevated OH· fluxes and in the presence of catalytic surfaces and thermal activation; degradation proceeds via stepwise dehalogenation and radical intermediates that are then oxidized and captured.
• Perfluorocarbons PFCs and fully fluorinated gases are the most persistent; OH· attack is slow in the troposphere, but combined strategies—localized OH· enhancement plus catalytic/thermal decomposition in the CO₂ Crusher—can promote defluorination and conversion to captureable fragments.
• Sulfur hexafluoride SF₆ is highly inert to OH·; targeted catalytic or thermal pathways are required for effective removal and are found in the air emitter and warmer conditions outside.

Nitrous oxide N₂O

$${\text{N}}_2\text{O is relatively unreactive with OH in the troposphere; mitigation requires catalytic decomposition or process controls.}$$

CO₂ cleavage stabilization and product formation

The CO₂ Crusher couples catalytic activation with controlled heat and low pressure to convert CO₂ and reactive carbon fragments into a condensed, inert carbon matrix. Conceptual steps:

Adsorption and activation

$$\mathrm{C}{\mathrm{O}}_2+\ast \to \mathrm{C}{\mathrm{O}}_2\text{\hspace{0.17em}⁣}-\text{\hspace{0.17em}⁣}\ast$$

Catalytic cleavage and intermediate formation Catalyst and thermal energy facilitate C–O bond weakening to form reactive intermediates (CO, C· species) and oxygenated fragments.

Recombination and condensation

$$\mathrm{n}\mathrm{C}\cdot \to ({\mathrm{C}}_{\text{amorphous}}{)}_{\mathrm{n}}$$

Controlled recombination yields a tetrahedral amorphous carbon product; oxygenated byproducts are captured, treated, and routed to appropriate waste streams. Process parameters steer product speciation toward solid, inert carbon and minimize volatile side‑products.

System design monitoring and operational safeguards

• Membrane generator design: a low‑moving‑parts membrane module produces a controlled OH· flux from oxygen in ambient air or CO₂‑rich feeds using catalytic surfaces, modest heating, and low pressure.
• Modularity and scalability: containerized units are networkable to scale coverage across a facility or airshed; units operate in parallel or independently.
• Real‑time tuning: OH· output and CO₂ Crusher conditions are adjusted in real time to match meteorology, ambient pollutant loads, and regulatory thresholds.
• Comprehensive monitoring: redundant sensors for CO₂, CH₄, N₂O, O₃, NOx, PM, temperature, humidity, and flow; mass‑flow meters record product streams.
• Meteorological gating: continuous local meteorology and dispersion modeling determine allowable generation windows; operations pause under inversion or poor dispersion.
• Automated interlocks: hard limits throttle or shut down generation if ozone, NOx, PM, or other thresholds are exceeded.
• Operator oversight: trained technicians supervise controls, maintenance, QA/QC, and emergency response; an MSDS for OH* and site‑specific EHS procedures are provided.

Verification safety and staged validation

Pilots produce auditable MRV datasets with baseline monitoring, continuous telemetry, tamper‑evident logs, and chain‑of‑custody for samples. Catalyst selection, thermal windows, and control logic are chosen to minimize ozone and NOx formation. Solids are sampled and analyzed to confirm inertness before reuse or storage. The Kamloops Hydroxyl Emitter pilot and the CO₂ Crusher scale‑up are delivering peer‑reviewed operational data and independent verification packages to validate efficacy, safety, and environmental neutrality.
