CarpeCarbon's First Italian DAC Plant Runs on Waste Heat, Not Just Megawatts

The most honest part of any direct air capture proposal is the energy bill. For every ton of CO₂ you pull from the atmosphere, you pay in kilowatt-hours, a hard number that tells you if the math works. Most startups in the space talk about their novel sorbents or elegant engineering. CarpeCarbon, a Turin-based company founded in 2022, starts with a different premise: find the heat that’s already being wasted, and plug in there.

Its first project is a pilot plant in Piedmont, designed to capture just under a thousand tons of CO₂ annually and lock it away as rock [Perplexity Sonar Pro Brief, retrieved 2024]. The more interesting figure is the one they claim for electricity: less than 300 kilowatt-hours per ton [Perplexity Sonar Pro Brief, retrieved 2024]. For context, that’s roughly the energy needed to run a residential air conditioner for two weeks. It’s a number that, if real, changes the conversation from whether DAC is possible to where you’d put it first.

The Wedge: A Plug for Every Chimney

CarpeCarbon’s bet is on integration, not isolation. Instead of building massive, energy-hungry standalone facilities, it designs modular, plug-and-play DAC units meant to slot into existing industrial sites [Forest Valley, retrieved 2026]. The core input isn’t grid electricity but low-grade waste heat,the kind billowing from factory chimneys, data centers, or power plants, typically too cool to be useful for anything else.

• OPEX arbitrage. By leveraging this otherwise-lost energy, the company claims it can reduce operating expenses by up to 90% compared to conventional DAC systems [Perplexity Sonar Pro Brief, retrieved 2024]. The unit economics hinge entirely on this free or very cheap thermal input.
• The non-intrusive sales pitch. The units are designed to connect without altering a host’s production cycles, a key concession for risk-averse plant managers [Forest Valley, retrieved 2026]. The value proposition to the host is either a share of the carbon credits generated or a supply of carbon-negative CO₂ for their own processes.
• The output options. Captured CO₂ can be directed toward permanent storage via mineralization or sold as a carbon-negative feedstock for synthetic fuels, beverages, or construction materials [Perplexity Sonar Pro Brief, retrieved 2024]. This flexibility aims to tap both compliance markets and voluntary industrial demand.

The First Italian Move

In November 2023, CarpeCarbon secured a €1.75 million (estimated $1.9M) pre-seed round to prove its concept [CDP Venture Capital, November 2023]. The investor syndicate is a who’s who of Italian public-private venture capital, suggesting a strong national strategic interest.

The funding announcement explicitly called CarpeCarbon “the first Italian company” dedicated to developing DAC for large-scale removal and storage, planting a flag in a country with significant industrial heat resources [CDP Venture Capital, November 2023]. The team, reportedly 13 professionals strong, spans engineering, physics, chemistry, and geology [Perplexity Sonar Pro Brief, retrieved 2024]. Founder and CEO Giuliano Antoniciello leads the effort, with co-founders covering commercial, financial, and human resources roles [RocketReach, retrieved 2026].

The Energy Math That Has to Hold

The grand claim of a 90% OPEX reduction is the linchpin. It’s also the hardest thing to verify from the outside. DAC is notoriously energy-intensive, primarily for the heat required to regenerate the chemical sorbents that catch the CO₂. If that heat is free, the model flips. But ‘free’ has conditions.

• Heat quality and consistency. Industrial waste heat isn’t always steady or at the right temperature. The unit’s design must be resilient to fluctuations, or the capture rate,and the credit revenue,becomes unpredictable.
• The host partnership. This is a B2B sale with a long lead time. Convincing a factory to host a first-of-its-kind unit involves permits, liability discussions, and integration work that go far beyond a simple equipment purchase.
• The competition. CarpeCarbon is entering a field with well-funded players like Climeworks and a crop of new entrants like Greenlyte Carbon Technologies and NeoCarbon. Their differentiation rests on the waste-heat wedge, but others are chasing similar efficiency gains through different means.

The company’s most plausible answer is its pilot. Building Italy’s first DAC plant, even at a modest scale, is a tangible milestone that moves the discussion from slides to steel [ToTeM, retrieved 2026]. Success will be measured in continuous runtime, actual energy draw from the grid, and the cost per ton verified by a third party.

What to Watch in Piedmont

The next twelve months are about turning a site plan into operating data. The Piedmont pilot is the company’s entire argument made physical. Key things to track:

• Final site and host announcement. Which industrial partner is providing the waste heat? The host’s profile will signal the model’s appeal to heavy industry.
• First captured ton and credit issuance. The timeline to generate and sell a verified carbon removal credit will test the entire operational and commercial stack.
• The next round. €1.75 million builds a pilot. Scaling to commercial units capable of capturing tens of thousands of tons annually will require a significantly larger round, likely Series A. The metrics from the pilot will determine its size and valuation.

Running the numbers on their energy claim provides a sense of the stakes. At 300 kWh per ton, capturing 1,000 tons a year requires about 300 MWh of electricity. In Italy, that might cost around €60,000 annually at industrial rates. The real savings are in the several gigawatt-hours of thermal energy they’re not buying. If a competitor’s system needs 2,000 kWh of electricity and 3,000 kWh-equivalent of heat per ton, CarpeCarbon’s back-of-the-envelope advantage is substantial. But only if the heat is truly there, and the capture works as advertised.

CarpeCarbon’s path to relevance doesn’t require beating Climeworks on global capacity tomorrow. It requires proving that the lowest-cost ton of CO₂ captured from air will come from the factory next door, not a standalone plant in the desert. That’s a different race entirely, and one just starting in Northern Italy.
