Eni has taken a bold step in its energy transition journey by signing a power offtake agreement worth more than $1 billion with Commonwealth Fusion Systems (CFS). The deal secures clean energy from CFS’s upcoming 400 MW ARC fusion power plant in Virginia, expected to deliver power to the grid in the early 2030s.
This agreement expands the long-term partnership between Eni and CFS, positioning fusion energy as a cornerstone of the future clean power market.
Eni CEO Claudio Descalzi said,
“This strategic collaboration, with a tangible commitment to the purchase of fusion energy, marks a turning point in which fusion becomes a full industrial opportunity. Eni has been strengthening its collaboration with CFS through its technological know-how since it first invested in the company in 2018. As energy demand grows, Eni supports the development of fusion power as a new energy paradigm capable of producing clean, safe, and virtually inexhaustible energy. This international partnership confirms our commitment to making fusion energy a reality, promoting its industrialization for a more sustainable energy future.”
Driving the Energy Transition: Eni’s Fusion Power Strategy
Eni, headquartered in San Donato Milanese, Italy, has been active in the US since 1968. Traditionally an oil and gas producer, the company has transformed into a broad energy leader. Today, Eni operates across oil, gas, renewables, and biofuels while also investing in cutting-edge energy transition technologies through its Boston-based venture arm, Eni Next.
The agreement with CFS underscores Eni’s role as both an energy provider and a pioneer in clean innovation. By locking in future fusion power supply, Eni gains an early-mover advantage in a market expected to revolutionize global electricity generation.
How CFS’s ARC Plant Is Shaping the Future of Energy
The centerpiece of the deal is CFS’s ARC plant, the world’s first grid-scale fusion power facility, currently under development in Chesterfield County, Virginia. Once operational, ARC will generate 400 MW of zero-carbon electricity, enough to power hundreds of thousands of homes.
CFS sees ARC as the launchpad for a new era of energy. After the Virginia project comes online, the company plans to replicate the model worldwide—building thousands of ARC plants to meet rising electricity demand.
ARC isn’t just about scale. It’s designed to integrate smoothly with existing grids and mimic the flexibility of natural gas plants—except without the carbon emissions. Operators will be able to adjust output quickly, making ARC an ideal partner for renewable sources like wind and solar.
Game-Changing Features
Fusion power has long been seen as a distant dream. ARC, however, is built for real-world deployment. Its design checks every box utilities look for in a new capacity:
-
Firm, clean power available on demand.
-
Compact footprint, about the size of a big-box store.
-
Rapid siting, thanks to its small land requirements compared to wind and solar.
-
Inherent safety, with no meltdown risk or long-lived nuclear waste.
-
Affordable electricity, expected to compete with or beat the cost of fossil fuel power.
Fusion’s fuel mix—deuterium and tritium—is abundant and cheap. A single truckload can supply 30 years of fuel for an ARC plant. With no exposure to volatile global commodity markets, ARC’s economics offer long-term price stability for customers.
Here’s what CFS ARC looks like:
Drawing Big Backers
The Virginia ARC plant has already attracted high-profile partners. In addition to Eni’s offtake agreement, Google has signed a deal to buy half of the plant’s electricity. The tech giant’s involvement highlights the growing interest from corporations looking for dependable, zero-carbon power.
CFS will finance, build, own, and operate the facility itself, creating hundreds of jobs in the Richmond region. With support from strategic partners like Eni and Google, CFS is on track to turn fusion from a lab experiment into a commercial industry.
Bob Mumgaard, Co-founder and CEO of CFS, also highlighted,
“The agreement with Eni demonstrates the value of fusion energy on the grid. It is a big vote of confidence to have Eni, who has contributed to our execution since the beginning, buy the power we intend to make in Virginia. Our fusion power attracts diverse customers across the world — from hyperscalers to traditional energy leaders — because of the promise of clean, almost limitless energy.”
Eni’s Bold Bet on Fusion and Net Zero Strategy
Eni has been betting on fusion since 2018, when it became one of the first investors in CFS. The company later boosted its stake during CFS’s $863 million Series B2 round. In 2023, the two firms signed a Collaboration Framework Agreement to share expertise, methodologies, and industry connections.
This latest offtake deal cements Eni’s role as a key player in commercializing fusion. For Eni, fusion is not just a side project—it’s part of its roadmap to achieve carbon neutrality by 2050.
To achieve this, the company is also transforming its operations, investing in clean energy, and supporting breakthrough technologies that can accelerate global decarbonization.
2050 Net-Zero Plan
Key strategies of net-zero goals include:
-
Cutting Carbon from Oil and Gas
Eni is cutting emissions from oil and gas by upgrading facilities, reducing methane leaks, and streamlining production. These steps help meet energy demand while lowering its carbon footprint. -
Scaling Renewables and Biofuels
The company is expanding solar and wind projects and boosting bio-refining capacity. By turning waste and feedstocks into low-carbon fuels, Eni targets emissions in aviation and shipping. -
Advancing Carbon Capture Solutions
CCS is key to Eni’s strategy. By installing it at industrial sites and power plants, the company locks away carbon and prepares for future negative emissions technologies. -
Driving Circular Economy Practices
Through circular initiatives, Eni recycles materials, reuses resources, and cuts waste. This reduces environmental impact while improving efficiency and lowering costs.
Fusion as the Next Frontier
The promise of fusion is clear: virtually limitless clean energy without the risks of traditional nuclear or the land demands of renewables. CFS’s progress, especially its advances in high-temperature superconducting magnets, shows the technology is moving from science fiction to reality.
According to the Fusion Industry Association’s latest report, the fusion industry secured $2.64 billion in private and public funding in the 12 months ending July 2025. Global investment in fusion has surged, reaching nearly $10 billion by mid-2025, driven by both public and private capital and rapid annual growth since 2020.
The U.S. and China lead the market, accounting for roughly 85% of total funding, with the private sector attracting most new investment. This marks a notable rise from 2024 and is the second-highest annual funding total since the report began, trailing only the 2022 record year.
As fusion edges closer to commercialization, early adopters like Eni and Google stand to gain significant advantages. They will secure reliable, zero-carbon energy sources at predictable prices, while also shaping the trajectory of a new global industry.
However, Eni’s $1 billion-plus deal with Commonwealth Fusion Systems is a landmark moment for the energy transition. It also signals fusion is moving from promise to practice.

For most businesses, the emissions that matter most sit outside their own walls. Scope 3 emissions, everything generated across your value chain, from the suppliers who make your inputs to the customers who use your products, typically make up the majority of a company’s total carbon footprint. Under the Corporate Sustainability Reporting Directive (CSRD), those value-chain emissions now have to be measured and disclosed with a rigour that spend-based estimates alone struggle to satisfy. This guide sets out how to improve Scope 3 data accuracy for CSRD: the calculation methods open to you, how to move from estimates to verified supplier data, and how to govern that data so it holds up to audit.
A carbon credit is a commitment that extends well into the future. The tonne of CO₂ compensated for today from a nature-based carbon project must remain out of the atmosphere for good, which means the forest behind the credit has to remain standing long after the transaction is complete. For any buyer, this raises a defining question: What ensures that the forest endures?
What replaced the cheap REDD credit on the boardroom slide deck, and why procurement is leading the rewrite.
Three years ago, a corporate slide showing a portfolio of cheap REDD+ credits could carry a board meeting. The number was big, the price was low, and the press release wrote itself. Today, that same slide gets sent back with questions. The questions are uncomfortable, the answers are unclear, and your general counsel is suddenly in the room.
Conventional carbon offsets are not dead. The voluntary carbon market retired 202 million tonnes in 2025, and the Morgan Stanley Institute for Sustainable Investing survey published in January 2026 confirmed that interest from corporate buyers remains substantial. What changed is the credibility threshold. The integrity floor has risen, the disclosure scrutiny has tightened, and the buyer profile has shifted. This article tracks what changed, what sophisticated buyers now ask before signing, and what serious corporates are putting on the board slide instead.
What boards used to buy, and why it stopped working
The 2020 to 2022 model was simple: buy a large tranche of avoidance credits at low single-digit prices, retire them against the company footprint, announce the carbon-neutral claim, and move on. Most of those credits came from REDD+ projects, renewable energy installations in countries where the renewable energy was already economic, or methane projects with thin documentation.
Several things broke that model. Academic research published in 2023, including a widely cited Science paper, found that the majority of REDD+ credits issued under the most common methodologies did not represent additional reductions when tested against rigorous counterfactuals. The Voluntary Carbon Markets Integrity Initiative published its Claims Code of Practice, which sets requirements for what companies can credibly claim from credit use. The European Union finalised its Green Claims Directive, restricting how companies can describe products as climate-neutral. France’s Décret 2022-539 already restricts carbon neutrality advertising. California’s AB 1305 imposes disclosure requirements on any company making net-zero or carbon-neutral claims while doing business in the state.
The collective effect: the cheap credit no longer buys the announcement, and the announcement now carries litigation risk.
The integrity reset: ICVCM, VCMI, and what changed
The Integrity Council for the Voluntary Carbon Market published the Core Carbon Principles in 2023 and began assessing methodologies against them in 2024. The first methodologies received the CCP label later that year. The point of the label is to give corporate buyers a defensible quality screen they can cite in disclosure.
The Voluntary Carbon Markets Integrity Initiative complements this on the demand side. Its Claims Code of Practice defines what a buyer can say (Silver, Gold, or Platinum claims, with associated requirements) based on the quality of credits used and the underlying decarbonisation strategy. Together, CCP and VCMI build a quality stack: CCP on the supply, VCMI on the claim, with the science-based target sitting underneath both.
The reset is not a ban on offsets. It is a ratchet. Credits that meet the new bar continue to clear; credits that do not, do not. The Morgan Stanley survey found that 61% of current buyers like the CCP label concept but that supply of labelled credits remains limited. That supply constraint is now visible in pricing.
What sophisticated buyers ask before they sign
The questions on the procurement scorecard have changed. A 2022 buyer might have asked about price, vintage, and project type. A 2026 buyer asks five different questions before any of those.
- What does the counterfactual look like, and who validated it.
- What is the permanence regime, and what is the buffer pool exposure.
- What is the leakage risk, and how is it mitigated.
- What rating has the project received from the independent ratings agencies (Sylvera, BeZero, Calyx Global), and what was the rationale.
- What is the documentation discipline that survives an audit four years from now when the procurement team that signed the contract has moved on.
If the vendor cannot answer those five questions on a first call, the conversation ends. Conversely, if the vendor can answer them with documented specificity, the conversation often expands beyond a single transaction toward a multi-year engagement.
Where this leaves your near-term commitments
You probably have near-term commitments that pre-date the integrity reset. Public targets to be carbon neutral by 2025 or 2030. Product-level claims that ran in last year’s marketing. Disclosed reduction trajectories that assumed continued access to cheap credits.
You have three workable paths. The first is to re-baseline your strategy, replacing the most exposed credits with higher-quality alternatives and adjusting the public language to match what you can defend. The second is to shift the underlying spend from offsetting outside your value chain to investing inside your value chain, where reductions count against Scope 3 directly and the audit trail is cleaner. The third is to keep the strategy and absorb the risk, which is increasingly the most expensive option once you price in litigation, restatement, and reputational exposure.
Most serious buyers are choosing the second path. It moves the carbon spend from a compliance cost to a procurement and resilience investment, and it removes the central failure point of the legacy model: the disconnect between where the emissions occurred and where the reductions sat. Nature-based supply chain investments, structured under the GHG Protocol Land Sector and Removals Standard and aligned to the SBTi FLAG Guidance, are the asset class that fits this brief. They generate inventory-grade reductions, they produce audit-grade documentation, and they survive the new claim restrictions because the carbon math sits inside the value chain that the disclosure already covers.
If you are reassessing a carbon strategy under the new integrity bar, or rebuilding a board narrative that has to survive a more skeptical audience, the carbon and sustainability experts at Carbon Credit Capital can help. The Dual-Value Model gives you a defensible alternative to legacy offset purchases, with the documentation and operational integration that survives the procurement scorecard and the audit.
