Sustaera DAC De-risking, 1 Deep Sky Partnership, 5, 000 Ton Pilot, and 1 MOU Signed (2024-2025)

DAC Commercial Projects, Sustaera Shifts Risk with Deep Sky Testbed

Sustaera is adopting a capital-light, validation-focused strategy by partnering with project developers like Deep Sky, outsourcing the infrastructure and permitting risks that have slowed larger, single-company deployments in the direct air capture sector.

Sustaera’s Validation-First Model

This approach prioritizes technology de-risking over premature megaton-scale capital expenditure. By leveraging an external partner for site development, Sustaera can concentrate its resources on optimizing its core capture technology and proving its economic model in a real-world setting.

• Unlike competitors such as Occidental’s 1 Point Five, which is investing heavily in its standalone 500, 000-ton-per-year Stratos facility, Sustaera is using its 2025 partnership with Deep Sky to test its technology at a more manageable pilot scale. The primary goal is to validate its proprietary DAC 2.0 system’s ability to achieve carbon removal costs below $100 per ton.
• The partnership model allows Sustaera to provide its capture technology while Deep Sky supplies the “Alpha” testbed facility, which includes the site, infrastructure, and operational support. This significantly reduces Sustaera’s upfront capital requirements and accelerates its path to generating performance data.
• Deep Sky’s “Alpha” facility, which began operations in August 2025, is a technology-agnostic testbed that also hosts systems from other developers, including Airbus and GE Vernova. This multi-vendor environment creates a valuable competitive benchmark, allowing potential investors and offtakers to compare performance under identical conditions.

Industry-Wide Capital Constraints

The broader Direct Air Capture market faces significant financial and execution risks, making Sustaera’s risk-mitigation strategy particularly relevant. High costs and deployment challenges have tempered initial enthusiasm, placing a premium on demonstrated performance.

• The strategy directly addresses the high financial exposure inherent in the DAC industry, where capture costs average between $500 and $900 per ton. This risk was highlighted by the U.S. Department of Energy’s cancellation of nearly $1 billion in funding for flagship DAC hubs in June 2026.
• By participating in a multi-technology hub, Sustaera accelerates its learning curve and generates credible, third-party-verified performance data. This data is essential for securing offtake agreements from corporate buyers and carbon market platforms, including large-scale purchasing consortiums like the Frontier Alliance.

Sustaera 1 Deep Sky MOU to Validate Canadian DAC Project (2025)

The May 2025 Memorandum of Understanding (MOU) with Deep Sky is Sustaera’s most significant commercial step to date, moving its technology from the laboratory to a multi-vendor operational environment designed to generate real-world performance metrics.

The Deep Sky “Alpha” Facility

This partnership provides Sustaera access to a purpose-built carbon removal center, enabling a faster and more efficient path to field testing. The facility is designed to host and compare multiple technologies side-by-side.

• Deep Sky’s “Alpha” facility in Canada is a first-of-its-kind carbon removal center engineered to test and validate different DAC and ocean-based carbon removal technologies simultaneously. This allows technology providers to “plug and play, ” connecting their capture units to existing infrastructure for power, site access, and CO 2 management.
• By outsourcing site selection, permitting, and infrastructure development to Deep Sky, technology companies like Sustaera can bypass years of development work and significant capital investment, focusing instead on their core competency of technology optimization.

Sustaera’s Pilot Scope

The proposed pilot project is of a significant scale for a validation phase, demonstrating a clear and deliberate pathway toward commercialization. Success at this stage is a prerequisite for future expansion.

• The project outlined in the MOU targets an initial carbon removal capacity of 1, 000 to 5, 000 tons of CO 2 annually. This scale is crucial for moving beyond lab-scale results and generating the data needed to engineer and finance larger facilities.
• A successful pilot will provide the necessary proof points for Sustaera to secure project financing and offtake agreements for its next phase of growth, which includes a planned 1 million ton-per-year facility targeted for 2027.

Canada Emerges as Hub for Sustaera’s DAC Pilot Program

Sustaera’s strategic focus shifted to Canada in 2025 for its initial field deployment, leveraging the country’s growing carbon removal ecosystem and the specialized infrastructure offered by project developer Deep Sky.

Deep Sky’s Canadian Infrastructure

The choice of Canada is directly tied to the availability of Deep Sky’s unique testbed, which provides a fast-track to operational validation. This move represents a key step in Sustaera’s transition from an R&D entity to a commercial player.

• While Sustaera’s development activities before 2025 were primarily centered in the United States, the partnership with Quebec-based Deep Sky marks its first major international initiative aimed at commercial-scale validation.
• Deep Sky is actively positioning Canada, particularly Quebec, as a global hub for carbon removal. The region’s abundant renewable energy resources and favorable geology for permanent CO 2 storage create an attractive environment for deploying energy-intensive DAC technologies.

Sustaera’s Future US Ambitions

Despite the Canadian pilot, Sustaera maintains a strategic roadmap focused on large-scale deployment in the United States. The Canadian project serves as a critical, de-risking stepping stone toward this goal.

• The data and operational experience gained from the Canadian pilot are intended to directly inform the engineering and financing of future, larger projects in the U.S. This includes a planned 1 million ton-per-year facility and potential involvement in government-supported initiatives like the Colorado DAC Hub.
• This dual-track geographic strategy allows Sustaera to leverage the immediate infrastructure advantages in Canada for technology validation while simultaneously preparing for large-scale industrial deployment in the U.S., where incentives like the 45 Q tax credit are strongest.

Sub-$100/Ton Target, Sustaera DAC 2.0 Moves to Pilot Stage

In 2025, Sustaera’s DAC 2.0 technology transitioned from lab-scale validation to pilot-scale deployment, with the primary objective of proving its economic viability and achieving its sub-$100 per ton cost target in an operational setting.

From Lab Bench to Field Test

The company’s focus has decisively shifted from theoretical efficiency to practical, sustained performance. The partnership with Deep Sky is the mechanism for this crucial transition.

• Between 2021 and 2024, Sustaera concentrated on research and development for its modular, electrically powered system, which utilizes a monolithic structured sorbent and resistive heating. Lab tests of this system demonstrated over 90% heating efficiency.
• The year 2025 represents a pivotal transition to field testing through the Deep Sky partnership. The goal is to collect performance data at a scale of 1, 000 to 5, 000 tons per year, which is necessary to validate engineering models and secure financing for commercial plants.

The $100/Ton Benchmark

Achieving the sub-$100 per ton cost target is the central pillar of Sustaera’s strategy, as it would make its technology highly competitive and profitable under existing policy frameworks. It would also attract large corporate buyers like Microsoft seeking scalable solutions.

• This cost target is a significant reduction from the current industry average, which stands at $500 to $900 per ton. At that price, many DAC projects are difficult to finance and depend on a small pool of buyers willing to pay a premium for high-quality carbon removal credits.
• Sustaera’s target cost is well below the U.S. 45 Q tax credit, which offers up to $180 per ton for CO 2 captured via DAC and stored permanently. If the pilot project validates this cost structure, Sustaera’s technology would be highly profitable under this regime, reducing its dependence on the voluntary carbon market.

SWOT Analysis, Sustaera’s Capital-Light Model and Tech Risk

Sustaera’s primary strength lies in its potentially disruptive low-cost technology and its capital-efficient partnership strategy. However, its main weakness is the unproven nature of this technology at a commercial scale, a risk the 2025 Deep Sky pilot is designed to address directly.

Sustaera’s Strategic Position

The company is positioned as a technology innovator leveraging a de-risked deployment model. Its success depends on translating lab-validated efficiencies into real-world operational performance and cost savings.

• The core competitive advantage is the modular DAC 2.0 system, which promises a significantly lower cost structure than incumbent technologies. This is paired with a prudent, capital-light strategy that outsources infrastructure risk.
• The primary threat is execution risk. If the technology fails to meet its sub-$100/ton cost and performance targets at the pilot scale, it will be challenging to attract the investment needed for its planned 1 million ton-per-year facility.
