Technical deep dives, industry analysis, and project updates from the CleanCycleCarbon team.
The tax code and the carbon registries ask different questions about the same captured ton. One pays for utilization. The other rejects it as a removal. Both are right.
Finding a backup CO₂ supplier takes a phone call. Approving one takes a supply-chain program under 21 CFR 117, and it cannot be built during a shortage.
Daily volume and delivery radius decide which CO₂ vent stacks are worth capturing, long before anyone runs a gas analysis.
CO₂ becomes immediately dangerous at 4 percent, a point where oxygen is still above 20 percent and no oxygen monitor will alarm.
A bulk CO₂ tank holds liquid near 0°F and 300 psi. What happens between the delivery ticket and the can, and why that gap is never zero.
Suppliers can cut volumes from inside the contract. Why two CO₂ agreements can still be one source, and what to check before the next shortage.
The One Big Beautiful Bill Act leveled Section 45Q: using captured CO₂ now earns the same credit as storing it. Beverage grade is the real bar.
From carbonation and cold chain to water treatment and welding, a field guide to where industrial CO₂ goes and why purity decides which jobs it can do.
Carbon dioxide is a regulated food ingredient. Beverage grade is the food safety compliance standard behind it, from FDA GRAS status to ISBT limits.
Merchant CO₂ tightens every summer as ammonia plants take maintenance and beverage demand peaks. The seasonal economics, and how buyers reduce the risk.
RNG upgraders produce a concentrated CO₂ stream, but concentration is not beverage grade. The value comes from purification, testing, and documentation.
Beverage grade CO₂ is not proven by the source alone. It is proven by purification, testing, documentation, and delivery controls before the product reaches.
Capturing CO₂ is only the first step. For food and beverage buyers, the sustainability value only matters when the product is purified, documented.
The RFS, LCFS, and Section 45Q were built for different goals. Together they are creating the conditions for a distributed, domestic CO₂ supply chain.
Every RNG upgrader built under the RFS or LCFS produces a concentrated CO₂ stream. RNG policy is quietly creating a distributed, domestic CO₂ supply chain.
The journey from raw industrial gas to the carbonation in your drink involves more steps than most people realize.
RNG upgraders vent tens of thousands of tons of CO₂ each year. Purified to beverage grade, that CO₂ becomes a second revenue stream most operators miss.
Most businesses never consider the emissions embedded in their CO₂ supply. Source, purification method, and transport distance all shape that footprint.
Cryogenic purification is the most reliable path to beverage grade CO₂. How the process works, why temperature matters, and what it means for quality.
A conflict involving Iran could disrupt urea and ammonia markets, tightening CO₂ supply for beverage and food producers who depend on reliable domestic sources.
The US CO₂ supply chain depends on a handful of large sources. When one goes down, whole regions feel it. Distributed domestic production fixes that.
The 2022 CO₂ shortage left beverage producers scrambling and prices up 50 percent. It was a predictable failure of a supply chain built without resilience.
Beverage grade CO₂ must meet 99.90 percent purity with strict limits on moisture, sulfur, benzene, and dozens of other contaminants.
RNG upgraders vent 35 to 45 percent of their gas stream as CO₂. Purifying that byproduct to beverage grade is a fast path to new domestic CO₂ supply.
An analysis of the U.S. industrial CO₂ market: supply concentration, demand growth, pricing trends, and where new supply will need to come from.
CO₂ enrichment in greenhouses can boost crop yields 20 to 30 percent. As controlled environment agriculture scales, demand for reliable CO₂ grows fast.
Large centralized plants dominate CO₂ supply today. Distributed capture at RNG facilities offers better economics and regional supply resilience.
Cryogenic distillation and chemical absorption are the two dominant CO₂ purification methods. A technical comparison of cost, purity, and operational tradeoffs.
Food grade CO₂ is FDA-defined under 21 CFR 184.1240 at 99.5 percent purity. What it covers, where it is used, and why beverage grade is the stricter bar.
Direct air capture, point-source capture, biogenic, and fossil-byproduct CO₂ are four different things with four different carbon-accounting outcomes.
The 45Q tax credit provides $60 per ton for CO₂ that is captured and utilized. Here is how it works, who qualifies, and how it affects project economics.
A practical walkthrough of how on-site carbon capture systems take raw waste gas and turn it into purified, beverage grade CO₂ ready for distribution.
