DAC Offtake Markets, Hyperscalers’ $725 B Capex Cycle, 105 Mtpa CO₂ Removal Demand, and 24+ Anchor Agreements (2021 to 2026)

Grid Constraints and AI Energy Demand: Hyperscalers’ Shift to Carbon Removal as a Strategic Necessity

Hyperscalers’ transition from passive buyers of renewable energy credits to active anchor tenants for the Carbon Dioxide Removal (CDR) market is a direct response to the intractable grid and power constraints created by the AI-driven data center expansion. The sheer scale of new energy demand has made it mathematically impossible for companies to meet 2030 climate targets through renewable energy purchases and operational efficiencies alone, forcing a strategic pivot to high-durability carbon removal to manage a ballooning carbon liability.

• Between 2021 and 2024, hyperscalers primarily focused on signing Power Purchase Agreements (PPAs) for wind and solar projects, treating decarbonization as a manageable accounting exercise centered on emissions avoidance. CDR was a small, speculative component of their climate portfolios, often pursued through small-scale purchases and venture-style initiatives.
• The period from 2025 to 2026 marked a fundamental shift driven by the materialization of AI’s energy footprint. With data center energy demand in the U.S. projected to surge by 130% by 2030, it became evident that intermittent renewables and grid upgrades could not keep pace. The problem evolved from a sustainability reporting issue to a critical business constraint tied to growth.
• This strategic pivot is confirmed by the actions of companies like Microsoft and Google, which now treat CDR not as a far-off option but as an essential tool to de-risk their binding 2030 net-zero commitments against the reality of explosive energy consumption. This has led them to underwrite the CDR industry through large, multi-year offtake agreements that provide the revenue certainty needed for project financing.

$725 B in Hyperscaler Capex, Microsoft and Google’s CDR Procurement Strategies

The massive $725 billion capital expenditure cycle projected for hyperscalers in 2026 is creating a parallel, non-discretionary spending stream for carbon removal, transforming CDR project financing from venture-backed speculation to bankable infrastructure underwritten by corporate offtake agreements. This capital outlay for data centers directly correlates with future energy consumption and emissions, making carbon management a core operational cost and a strategic imperative.

• According to a Carbon Direct analysis, the four largest hyperscalers require investments of $70-80 billion in projects capable of sequestering over 105 million metric tons of CO₂ per year (Mtpa) to meet their climate goals, a volume that exceeds the entire global operational capture capacity as of April 2026.
• This demand has catalyzed institutional-grade investment mechanisms, such as the Frontier buyer’s club, which pledged to invest over $900 million into CDR companies. This signals a market shift from small, pilot-scale purchases to large, structured procurement designed to build a functioning supply chain.
• The scale of this new demand has attracted sophisticated capital from firms like Temasek, which is forming alliances to service this emerging market, and is also forcing investment into adjacent energy infrastructure, from nuclear projects explored by firms like Brookfield Nuclear to dedicated power ventures like Clean Core AI & Data Center Energy.

Table: Hyperscaler Capex and Data Center Market Growth (2026-2034)

Hyperscalers Dominate Carbon Removal Purchases
Microsoft leads corporate ‘tonnes purchased” with 626,000 tonnes, far outpacing other buyers like Altitude (425,000) and JPMorgan Chase (60,938). This extreme concentration underscores hyperscalers” critical role as anchor tenants, driving over 50% of the listed demand.

Anchor Tenants De-Risk Nascent CDR Market, But Concentration Poses Risk
The heavy reliance on a few large buyers, particularly hyperscalers, provides essential early demand signals and capital for the nascent carbon removal market. This enables CDR project developers to achieve scale and attract investment, de-risking the market for future entrants, but also highlights market fragility if these anchor tenants shift strategies.

Hyperscalers Lead CDR Market with Microsoft at the Forefront
Microsoft dominates the corporate carbon removal market, purchasing 52.35 million metric tons of CO2e in 2025, significantly outpacing all other buyers. This positions hyperscalers as the primary anchor tenants, driving demand and market liquidity for nascent CDR solutions.

US Data Center Growth, Hyperscaler Impact on CDR Projects

While the AI data center buildout is a global phenomenon, the United States has become the undisputed epicenter of hyperscaler-driven CDR demand due to the heavy concentration of new data center construction and favorable policy environments. This is creating regional ecosystems where new CDR projects are being developed in close proximity to the massive power and data infrastructure serving the AI industry.

• Between 2021 and 2024, the geography of CDR development was primarily dictated by geological suitability for sequestration or specific policy incentives, such as in Iceland or the UK. Activity was dispersed and had limited direct connection to the locations of specific corporate buyers.
• Starting in 2025, the geography of CDR began to mirror the geography of data centers. The U.S., with its projected 130% increase in data center energy demand, became the primary market where the problem of carbon liability is most acute and the demand for offtake is highest.
• Proposals for single, massive data center campuses, such as the once-planned Wonder Valley project in Utah with projected annual emissions of up to 30.5 megatons of CO 2, illustrate the scale of the localized carbon problem that hyperscalers must solve, thereby creating intense regional demand for CDR.
• Other nations like Canada are also experiencing rapid growth in their data center markets, with a projected CAGR of 16.5%, indicating that the pattern of co-locating data centers, clean power, and carbon removal infrastructure will become a global model for hyperscaler expansion.

DAC and CCUS Commercialization, Hyperscalers as Anchor Tenants for CDR Technology

Hyperscalers have fundamentally accelerated the commercialization path for high-durability CDR technologies like Direct Air Capture (DAC) and Carbon Capture, Utilization, and Storage (CCUS) by providing the long-term, bankable offtake agreements required to de-risk first-of-a-kind projects. This corporate demand has unlocked project finance and attracted institutional capital, shifting the sector from grant-funded research to industrial-scale deployment.

• Before 2025, CDR technologies like DAC were predominantly in the pilot and demonstration phase, sustained by government grants and early-stage venture funding. The primary barrier to scale was a prohibitive cost curve and the absence of a guaranteed revenue stream to secure debt financing for large projects.
• In 2025-2026, the market structure inverted. The urgent need for millions of tons of verifiable removal established hyperscalers as a new class of “anchor tenants.” Their multi-year, fixed-price purchase commitments now function as the revenue guarantees needed to make capital-intensive CDR projects bankable.
• This shift is validated by commercial discussions between industrial majors like Exxon Mobil and AI hyperscalers for large-scale carbon management services. These conversations have moved from the theoretical to the transactional, focusing on deploying industrial-scale infrastructure to meet contractual obligations.
• While DAC is a central focus, hyperscalers are pursuing a portfolio of solutions to ensure 24/7 clean operations. This includes massive renewable energy procurements, as seen with Meta‘s solar projects, and investments in enabling technologies like battery energy storage to manage grid intermittency.

Microsoft Dominates CDR Contracts, Delivery and Retirement Lag
Microsoft is the dominant anchor tenant in durable Carbon Dioxide Removal (CDR) contracting, representing 79% of the 46.4M tonnes contracted. This significant commitment underscores their role in stimulating the nascent CDR market, although their share drops to 7% of delivered and 6% of retired tonnes, indicating a substantial gap between commitments and actual verified removal across the industry.

Hyperscaler Commitments Fuel CDR, But Delivery Hurdles Persist
Hyperscaler commitments are crucial for de-risking and funding the early-stage CDR market, providing the necessary capital and market signal for developers to innovate and scale. The large disparity between contracted, delivered, and retired tonnes (46.4M vs. 1.3M vs. 723.7K) highlights the immense technical, operational, and financial hurdles in bringing carbon removal projects to full verified completion.

Hyperscalers Lead Carbon Removal Purchases by Volume
Microsoft, a leading hyperscaler, dominates carbon removal purchases with 626,000 tonnes, nearly 50% more than the next largest buyer, Altitude (425,000 tonnes). This significant volume establishes hyperscalers as critical anchor tenants, driving initial market scale and demand for nascent CDR technologies.

2027 Scenario: Will Hyperscaler CDR Demand Outstrip Supply?

The most critical variable for the CDR market in 2027 and beyond is whether the supply side can execute and scale projects fast enough to meet the compounding demand from hyperscalers. The primary signals to monitor will be project execution velocity, cost-down trajectories for key technologies, and the structure of next-generation offtake agreements.

• If this happens: Large-scale DAC and CCUS projects that were announced in 2025-2026 successfully reach Final Investment Decision (FID) and commence construction on schedule, providing a clear line of sight to new supply entering the market post-2028.
• Watch this: The market price for high-durability CDR credits. A stable or gradually declining price, particularly for DAC credits in the $400-$600/ton range, would indicate that supply is expanding in line with demand. A sharp or sustained price increase would signal a significant supply crunch and execution challenges.
• These could be happening: In a supply-constrained scenario, expect hyperscalers to move beyond simple offtake agreements toward deeper vertical integration. This could include acquiring CDR developers, providing direct project equity, or forming exclusive joint ventures with energy and engineering majors to secure a captive supply of carbon removals.
