The Carbon to Crystals Solution: Modular Mineralization & Dual Revenue
Turn industrial CO₂ emissions into $85/ton 45Q tax credits and $400-850/ton CaCO₃ product. Skid-mounted, 5-12 month deployment.
Traditional carbon capture is a multi-year, multi-million dollar construction project that generates zero revenue until operational. Tandem Carbon 's Carbon to Crystals solution redefines industrial mineralization. By utilizing proprietary, skid-mounted modules that attach directly to your existing flue stacks, we turn a compliance liability into a verifiable, revenue-generating asset in 5-12 months.
The Carbon to Crystals Process: From Flue Gas to Financial Assets
Our process is engineered specifically for dilute CO₂ streams (3–5%), such as those found in gas data centers and power generation.
Flue Gas Conditioning
Our integrated MVR (Mechanical Vapor Recompression) heat exchangers reduce parasitic power draw by up to 95% compared to traditional shell-and-tube systems, using a fraction of the physical footprint. Hot flue gas is cooled and conditioned for maximum chemical capture efficiency.
Triple-Stream Chemical Capture
The conditioned gas passes through an aqueous scrubber that absorbs CO₂, NOx, and SOx simultaneously. This single-pass process isolates the carbon oxides and leaves a clean effluent gas ready for atmospheric release.
Mineralization to High-Purity CaCO₃
The captured carbonates are reacted with calcium chloride (CaCl₂) to precipitate high-purity Calcium Carbonate (CaCO₃). This reaction is highly efficient, achieving a verified 99% capture rate and producing a solid, permanently sequestered mineral product.
Product Purification & Closed-Loop Recycling
The resulting CaCO₃ is purified to 98% purity with a 4.0 µm particle size—specs that command premium pricing in the industrial PCC market. The remaining chemical solution is regenerated via bipolar membrane electrolysis, requiring only 10% makeup and recycling 95% of process water.
Third-Party Validated at Industrial Scale
This technology has moved beyond theoretical modeling. The Carbon to Crystals process has been validated through rigorous, real-world industrial testing:
Stable Capture Capacity
Successfully processed over 1.5 TPD (1,130 lbs/hr gas flow), exceeding design specs while maintaining 98% CaCO₃ purity.
Autonomous Operation
Independent engineering firms confirmed stable, fully autonomous hydraulic mineralization operation.
Global Recognition
Designated a Semi-Finalist in the 2017 Carbon Removal XPRIZE, validating technical viability on a global stage.
The Economics: From Compliance Liability to 10-Year Revenue
Most capture pathways are pure OPEX drains. Carbon to Crystals is a dual-revenue engine. At a standard 25 MW facility, capturing 99% of emissions unlocks a massive dual-revenue baseline over 10 years:
The Government Floor
$85/ton in 45Q federal tax credits for permanent mineralization (under the OBBBA parity provision).
The Commodity Upside
$400–$850/ton in sellable CaCO₃ mineral sales to paper, paint, and plastic manufacturers.
The Bottom Line: $314M Base Case Value per facility.
This represents a 9.4× to 20× higher return than single-credit paths.
