Today, we’re talking about carbon capture, more specifically, about how carbon capture evolves into industrial manufacturing.
The central question behind this investment was simple: Can carbon capture integrate into heavy industry in a way that strengthens business fundamentals rather than weakening them?
To answer that, we need to walk through: the structural gap in carbon capture, the biological lens to it, and how Intrinsic is addressing this.
The Structural Gap in Carbon Capture
For the last several decades, the dominant carbon capture technology has been the amine system.
An amine system uses chemical solvents - typically amine-based liquids - that absorb CO₂ from flue gas streams. The flue gas is passed through a column where the solvent chemically binds to carbon dioxide. The solvent is then heated in a separate unit to release the CO₂ in concentrated form, after which the solvent is reused in a continuous cycle.
It works. The chemistry is well understood. Large-scale facilities have been built globally.
So why hasn’t adoption scaled? Because the economics create a structural gap.
In simple terms, installing an amine system means:
Spending large upfront capital - Capture costs typically range between $60–100 per tonne when regeneration and storage are included.
Consuming additional energy to run the system - power plants can lose 20–30% of output just to operate the capture unit.
Paying to compress, transport and store CO₂- Storing the CO₂ without generating new product revenue
As an industrial operator, this would mean higher capex and opex costs - without selling anything new. In other words, you spend money to remove something, and then you pay more money to bury it.
In markets with strong carbon compliance policies, that cost can be justified. In India, where cement and steel operate on thin margins and where there is no widespread CO₂ storage infrastructure, the financial incentive is weak.
That is the structural gap.
Carbon capture reduces emissions, but it does not improve the income statement. If that equation remains unchanged, adoption remains limited.
The Biological Lever in CCUS
So far, most carbon capture approaches have focused on physical, chemical separation and storage. The biological lever introduces a different idea: instead of separating CO₂ and burying it, convert it into something valuable.
Biologically, microalgae naturally fix carbon through photosynthesis, converting roughly 1.8–2x their weight in CO₂ into biomass. That biomass contains proteins, pigments, lipids, and specialty compounds that already have established markets.
Conceptually, this reframes carbon as feedstock.
However, previous biological approaches faced real-world constraints: industrial flue gas is not clean.
It fluctuates between 8–15% CO₂ and contains SOₓ, NOₓ, and particulates. Many algal strains optimized in laboratories struggled above 35°C, while industrial zones in India regularly reach 48–50°C. Productivity in earlier systems often stayed at 0.2–0.3 g/L/day, with capture efficiency around 40–60%. Photobioreactors made of borosilicate glass were capital-intensive and fragile, costing ₹20–30 lakh per kL
The biological pathway was promising, but the architecture was not built for industrial volatility.
Enter Intrinsic Foundries.
What Intrinsic Foundries did differently was design the system around industrial conditions.
They developed a carbon banking mechanism that buffers CO₂ as bicarbonate within the growth medium, storing up to 6 g/L equivalent per liter. When the flue gas supply dips, photosynthesis continues using stored carbon, and the capture efficiency remains in the 70–80% range.
They curated a non-GMO strain library tolerant to high CO₂ concentrations, impurities, and ambient heat up to 50°C.
They also redesigned the reactor manufacturing through on-site PMMA extrusion, reducing per-kL capex by roughly 60% at scale.
The shift is subtle but important: the system adapts to the factory, not the other way around.
Why This Matters to Transition VC
Here are Gaurav Patil’s thoughts:
At Transition VC, we invest in engineering-led infrastructure that can stand on its own economics. Our mandate has always been clear: back companies that build real systems for the energy transition, particularly in markets where capital discipline and operating constraints are non-negotiable.
We focus on platforms that do not rely solely on subsidies, sentiment, or regulatory timing. We look for architectures where environmental impact compounds because the business model compounds. Where throughput drives both revenue and decarbonization. Where technology is designed for industrial reality, not laboratory conditions.
Intrinsic Foundries fits squarely within that lens.
India, and the broader Global South, will not decarbonize through imported solutions optimized for different cost structures and infrastructure environments. The transition here will be built by companies that understand heat, volatility, capital efficiency, and margin pressure. It will be built by founders who breathe these constraints.
To us, Intrinsic doesn’t simply promise carbon utilization, they have the clarity of integration: capture embedded at point source, modular hardware designed for industrial environments, and downstream value creation that strengthens the income statement of the emitter. This is the type of platform we believe defines the next decade of industrial decarbonization: Engineering-first, economically aligned, and globally relevant.
And that is precisely why we are backing them.
